Surgery

Reintervention rates after uterus-preserving surgery for leiomyomata were lowest after vaginal myomectomy, the most frequent among four therapeutic approaches, a large cohort study reported.

Accounting for censoring, the 7-year reintervention risk for vaginal myomectomy was 20.6%, followed by uterine artery embolization (26%), endometrial ablation (35.5%), and hysteroscopic myomectomy (37%).

Hysterectomies accounted for 63.2% of reinterventions according to lead author Susanna D. Mitro, PhD, a research scientist in the Division of Research and Department of Obstetrics and Gynecology at Kaiser Permanente Northern California, Oakland, and colleagues.

The Study

In a cohort of 10,324 patients ages 18-50, 19.9% were Asian, 21.2% Black, 21.3% Hispanic, and 32.5% White, with 5.2% of other races and ethnicities. The most affected age groups were 41-45 and 46-50 years. All participants underwent a first uterus-preserving procedure after leiomyoma diagnosis according to 2009-2021 electronic health records at Kaiser Permanente Northern California.

Reintervention referred to a second uterus-preserving procedure or hysterectomy. Median follow-up was 3.8 years (interquartile range, 1.8-7.4 years), and the proportions of index procedures were as follows: 18% (1857) for hysteroscopic myomectomy; 16.2% (1669) for uterine artery embolization; 21.4% (2211) for endometrial ablations; and 44.4% (4,587) for myomectomy.

Reintervention rates were higher in younger patients after uterine artery embolization, with patients ages 18-35 at the index procedure having 1.4-3.7 times greater reintervention rates than patients ages 46-50 years. Reintervention rates for hysteroscopic myomectomy varied by parity, with multiparous patients at 35% greater risk than their nulliparous counterparts.

On the age issue, the authors note that symptom recurrence may be less common in older patients, perhaps because of the onset of menopause. “Alternatively, findings may be explained by age-specific care strategies: Older patients experiencing symptom recurrence may prefer to wait until the onset of menopause rather than pursuing another surgical treatment,” they wrote.

A recent study with 7 years’ follow-up reported a 2.4 times greater risk of hysterectomy after uterine artery embolization versus myomectomy. Reintervention rates may be lower after myomectomy because otherwise asymptomatic patients pursue myomectomy to treat infertility, the authors wrote. Alternatively, myomectomy may more completely remove leiomyomas.

These common benign tumors take a toll on healthcare resources, in 2012 costing up to $9.4 billion annually (in 2010 dollars) for related surgeries, medications, and procedures. Leiomyomas are reportedly the most frequent reason for hysterectomy.

Robust data on the optimal therapeutic approach to fibroids have been sparse, however, with a 2017 comparative-effectiveness review from the Agency for Healthcare Research and Quality reporting that evidence on leiomyoma treatments was insufficient to guide clinical care. Few well-conducted trials of leiomyoma treatment have directly compared different treatment options, the authors noted.

The rate of myomectomy is reported to be 9.2 per 10,000 woman-years in Black women and 1.3 per 10,000 woman years in White women, and the recurrence rate after myomectomy can be as great as 60% when patients are followed up to 5 years.

The authors said their findings “may be a reference to discuss expectations for treatment outcomes when choosing initial uterus-preserving treatment for leiomyomas, especially for patients receiving treatment years before the likely onset of menopause.”

A longer time between hysteroscopic polypectomy and frozen embryo transfer may improve the odds of successful pregnancy, based on data from a new analysis presented at the annual meeting of the Society for Reproductive Investigation.

Although uterine polyps have a negative effect on pregnancy rates, data supporting a specific time interval between hysteroscopic polypectomy (HP) and frozen embryo transfer (FET) are limited, according to Audrey Messelt, MD, of Baylor College of Medicine, Houston, Texas, and colleagues.

“Hysteroscopic polypectomy is a common procedure performed before embryo transfer to optimize the receptivity of the endometrium. Currently, there is no ideal recovery time lapse between surgery and an embryo transfer,” said senior author Laura Detti, MD, professor of obstetrics and gynecology at Baylor, in an interview. “This is often the last step prior to embryo transfer, and identifying a recovery time that allows the best outcome is important.”

In a retrospective analysis, the researchers examined the effect of the time between HP and FET on pregnancy outcomes. They identified 65 patients with uterine pathology based on saline-infusion sonogram who underwent hysteroscopy and FET between June 1, 2022, and September 30, 2023.

The endometrial preparation for FET included sequential administration of oral or transdermal estradiol and intramuscular progesterone.

Overall, 46 patients were diagnosed with endometrial polyps at the time of surgery; three had endometritis, one had a uterine septum that was resected, 15 had no abnormal pathology or had normal endometrium at the time of examination. No cases of hyperplasia or malignancy were identified.

A total of 58 patients underwent FET with a single euploid embryo, four with a single untested embryo, one with a low-mosaic embryo, and two with a double-embryo transfer (one euploid and one low mosaic).

After FET, 50 patients conceived and 15 did not. Patients with ongoing pregnancies who had a history of endometrial polyps had significantly more days from surgery to FET, compared to patients with a history of polyps who failed to conceive (median 70 days vs 45 days, P = .01).

By contrast, the time between hysteroscopy and FET was similar among patients with no endometrial pathology who did and did not have ongoing pregnancies (median 45 vs 52.5 days, P = .95).

The findings were limited by the relatively small sample size and exclusion of patients with pathologies other than polyps, as well as a lack of data on age group breakdowns. However, the results suggest that patients with uterine polyps may benefit from more time between HP and FET, while patients with normal surgical findings could undergo FET sooner, the researchers concluded.
 

Postpolypectomy Timing May Affect Pregnancy Outcomes

“We used to think that having had the first menses from surgery would be enough recovery time for the uterine cavity, even if it was just 2 weeks,” Dr. Detti said in an interview. “This still holds true when no endometrial polyps are diagnosed in the pathological specimen; however, we learned that if endometrial polyps are removed at the time of hysteroscopy, the ideal recovery time prior to an embryo transfer should be longer,” she said.

The current study is important because approximately 15% of women are diagnosed with endometrial polyps during their reproductive years, said Mark P. Trolice, MD, professor at the University of Central Florida, Orlando, and founder/medical director of the IVF Center of Central Florida in Winter Park, in an interview.

“Abnormalities of the uterine cavity have been shown to reduce embryo implantation and increase the risk of miscarriage,” said Dr. Trolice. Although the impact of small endometrial polyps on fertility and pregnancy are uncertain, most infertility specialists recommend removal of endometrial polyps via hysteroscopic polypectomy in general and prior to IVF embryo transfer in particular, he said.

Although infertility patients are anxious to undergo embryo transfer, the current study suggests a benefit in delaying the procedure following the removal of any polyps identified during the pretransfer evaluation, Dr. Trolice said in an interview. As for additional research, “it would be helpful to know the age group breakdown of patients and if the results were consistent among all categories,” he said.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Trolice had no financial conflicts to disclose and serves on the Editorial Advisory Board of Ob.Gyn. News.

Minimally invasive cytoreductive surgery for epithelial ovarian cancer appears to be safe and does not compromise survival, compared with open surgery, when patients have completely resected tumors.

This was a finding of a retrospective study presented by Judy Hayek, MD, during an oral abstract session at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, in San Diego.

Among 2,412 women in the National Cancer Database with tumor-free surgical margins (R0 resections) after interval debulking surgery (IDS), the median overall survival (OS) was 46 months for those who had undergone an open procedure or minimally invasive surgery (MIS) that was converted to an open procedure. In contrast, the median OS was 51 months for patients who underwent laparoscopic or robot-assisted minimally invasive surgery, reported Dr. Hayek, a gynecologic oncology fellow at SUNY Downstate Health Sciences University in Brooklyn, New York.

“R0 resection at the time of interval debulking surgery has similar survival outcomes by minimally invasive surgery versus laparotomy, while R0 resection via laparotomy is associated with higher perioperative mortality. There is no interaction between the extent of surgery and the impact of MIS on survival,” she said during her presentation.

The session included a debate on the pros and cons of minimally invasive vs. open surgery in this population.
 

Growing Use of MIS

Over the last decade, minimally invasive surgery for interval debulking was shown to be safe and feasible. More recently, two studies using National Cancer Database cohorts showed that survival was similar and perioperative outcomes were better with a minimally invasive approach at the time of IDS for patients with early disease, Dr. Hayek said (Obstet Gynecol 2017 Jul;130(1):71-79; and Gynecol Oncol 2023 May:172:130-137).

Potential limitations of MIS include the absence of haptic feedback compared with open surgery, and the possibility that limited visualization of the surgical field could lead to missed residual disease and subsequent poor outcomes for patients who were presumed to have complete gross resections, she said.
 

Outcomes Compared

Dr. Hayek and colleagues conducted their study to evaluate survival outcomes after R0 resections by MIS or laparotomy in IDS for patients with advanced epithelial ovarian cancer.

As noted before, they looked at outcomes for 2,412 women with stage IIIC or IV cancers of all histology types who were diagnosed from 2010 through 2019. A total of 624 patients (25.9%) had minimally invasive procedures, and 1,788 (74.1%) had open surgery or MIS that had been converted to open procedures.

Of the minimally invasive procedures, 48.7% were robot-assisted, and the remainder were laparoscopic.

Over the decade of the study, the frequency of minimally invasive surgery steadily increased, from 11.9% of all procedures in 2010 to 36.5% in 2019.

Also as noted, there was no difference in median overall survival, at 46 months for open/converted procedures vs. 51 months for minimally invasive procedures.

As might be expected, the mean length of stay was shorter with the less invasive surgery: 3.3 days compared with 5.3 days with open surgery (P less than .001). In addition, 30-day and 90-day mortality rates were also lower with MIS, at 0.8% and 1.9%, respectively, compared with 1.6% and 3.5% with laparotomy (P = .006 for 30-day mortality, and .003 for 90-day).

There were also no differences in overall survival between the procedure types when the cases were stratified according to extent of surgery. Within the minimally invasive surgery groups there were no differences in median OS for patients whose surgery was performed laparoscopically or with robotic assistance.

The study was limited by a lack of data on either patient-specific tumor burden, neoadjuvant chemotherapy use, progression-free survival, cause of death, or surgical morbidity, Dr. Hayek acknowledged.
 

MIS Use Debatable: CON

Despite the good outcomes with minimally invasive techniques in this favorable-risk population, critics contend that MIS interval cytoreduction is too risky in the majority of cases.

In the debate portion of the session, Kara Long Roche, MD, an associate attending in the section of ovarian cancer surgery at Memorial Sloan Kettering Cancer Center in New York, argued that the potential for MIS missing residual disease is too great.

“We know from almost every retrospective and prospective study done that the volume of residual disease after debulking, whether primary or interval, is the most important prognostic factor for our patients that we can modify,” she said.

Rather than debating morbidity, mortality, or criteria for resection, “I would argue that the question we need to debate is can MIS interval debulking achieve a completeness of resection, i.e., volume of residual disease?” she said.

Dr. Roche contended that retrospective studies such as that reported by Dr. Hayek cannot adequately answer this question because of selection bias. Patients selected for MIS have better responses to neoadjuvant chemotherapy and more favorable tumor biology; and, therefore, overall survival may not be the optimal endpoint for retrospective studies.

In addition, neoadjuvant chemotherapy does not automatically preclude the need for extensive upper abdominal surgery since almost half of patients who receive neoadjuvant chemotherapy are found to have bulky upper abdominal disease at the time of debulking.

Dr. Roche especially cautioned against what she called the WNL or “We Never Looked” phenomenon, in which patients are found on open surgery and organ mobilization to have disease that was not evident on presurgical imaging.

She acknowledged that for some patients the risks of laparotomy are likely to outweigh the benefit of a radical resection, and stressed that for such patients forgoing surgery or optimizing perioperative care may be more important than the size of the incision.

MIS IDS should be the exception, not the rule. We need prospective data with appropriate endpoints. We need surgical quality control in both arms, and we need to continue to focus on surgical education and training so that our trainees can graduate doing these procedures via any approach,” she concluded.
 

Debate: PRO

Arguing in favor of MIS for ovarian cancer, J. Alejandro Rauh-Hain, MD, MPH, associate professor of gynecologic oncology at the University of Texas MD Anderson Cancer Center in Houston, told attendees “the only bias I have is that I actually love doing open surgery, but I’m going to try to convince you that there is a potential role for minimally invasive surgery in the future for selected patients with ovarian cancer after neoadjuvant chemotherapy.”

He noted that several studies have convincingly shown that neoadjuvant chemotherapy does not adversely affect oncologic outcomes for patients with advanced-stage ovarian cancer, and decreases perioperative morbidity in patients who receive it, including reductions in serious adverse events, risk of stoma, and 30-day postoperative mortality.

In addition, low use of neoadjuvant chemotherapy is associated with increased risks for 90-day postoperative deaths in both low- and high surgical volume centers in the US, according to unpublished National Cancer Database data.

Dr. Rauh-Hain noted that neoadjuvant chemotherapy use has steadily increased from 2010 through 2020, and added that in 2022, 32% of interval cytoreductive surgeries in the United States were performed with a minimally invasive approach.

To get a better handle on the MIS vs. open-surgery question, Dr. Rauh-Hain and colleagues at MD Anderson and 13 other centers in the United States, Canada, and Europe are currently recruiting patients for the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial. In this phase 3 noninferiority study, patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who have complete or partial responses and CA125 normalization after three or four cycles of neoadjuvant chemotherapy will be randomized to laparotomy or MIS, followed by adjuvant platinum- and taxane-based chemotherapy.

The study by Hayek et al. was internally supported. Dr. Hayek and Dr. Roche reported having no conflicts of interest. Dr. Rauh-Hain disclosed financial relationships with Guidepoint Consulting, and the Schlesinger Group.

As noted before, they looked at outcomes for 2,412 women with stage IIIC or IV cancers of all histology types who were diagnosed from 2010 through 2019. A total of 624 patients (25.9%) had minimally invasive procedures, and 1,788 (74.1%) had open surgery or MIS that had been converted to open procedures.

Of the minimally invasive procedures, 48.7% were robot-assisted, and the remainder were laparoscopic.

Over the decade of the study, the frequency of minimally invasive surgery steadily increased, from 11.9% of all procedures in 2010 to 36.5% in 2019.

Also as noted, there was no difference in median overall survival, at 46 months for open/converted procedures vs. 51 months for minimally invasive procedures.

As might be expected, the mean length of stay was shorter with the less invasive surgery: 3.3 days compared with 5.3 days with open surgery (P less than .001). In addition, 30-day and 90-day mortality rates were also lower with MIS, at 0.8% and 1.9%, respectively, compared with 1.6% and 3.5% with laparotomy (P = .006 for 30-day mortality, and .003 for 90-day).

There were also no differences in overall survival between the procedure types when the cases were stratified according to extent of surgery. Within the minimally invasive surgery groups there were no differences in median OS for patients whose surgery was performed laparoscopically or with robotic assistance.

The study was limited by a lack of data on either patient-specific tumor burden, neoadjuvant chemotherapy use, progression-free survival, cause of death, or surgical morbidity, Dr. Hayek acknowledged.
 

MIS Use Debatable: CON

Despite the good outcomes with minimally invasive techniques in this favorable-risk population, critics contend that MIS interval cytoreduction is too risky in the majority of cases.

In the debate portion of the session, Kara Long Roche, MD, an associate attending in the section of ovarian cancer surgery at Memorial Sloan Kettering Cancer Center in New York, argued that the potential for MIS missing residual disease is too great.

“We know from almost every retrospective and prospective study done that the volume of residual disease after debulking, whether primary or interval, is the most important prognostic factor for our patients that we can modify,” she said.

Rather than debating morbidity, mortality, or criteria for resection, “I would argue that the question we need to debate is can MIS interval debulking achieve a completeness of resection, i.e., volume of residual disease?” she said.

Dr. Roche contended that retrospective studies such as that reported by Dr. Hayek cannot adequately answer this question because of selection bias. Patients selected for MIS have better responses to neoadjuvant chemotherapy and more favorable tumor biology; and, therefore, overall survival may not be the optimal endpoint for retrospective studies.

In addition, neoadjuvant chemotherapy does not automatically preclude the need for extensive upper abdominal surgery since almost half of patients who receive neoadjuvant chemotherapy are found to have bulky upper abdominal disease at the time of debulking.

Dr. Roche especially cautioned against what she called the WNL or “We Never Looked” phenomenon, in which patients are found on open surgery and organ mobilization to have disease that was not evident on presurgical imaging.

She acknowledged that for some patients the risks of laparotomy are likely to outweigh the benefit of a radical resection, and stressed that for such patients forgoing surgery or optimizing perioperative care may be more important than the size of the incision.

MIS IDS should be the exception, not the rule. We need prospective data with appropriate endpoints. We need surgical quality control in both arms, and we need to continue to focus on surgical education and training so that our trainees can graduate doing these procedures via any approach,” she concluded.
 

Debate: PRO

Arguing in favor of MIS for ovarian cancer, J. Alejandro Rauh-Hain, MD, MPH, associate professor of gynecologic oncology at the University of Texas MD Anderson Cancer Center in Houston, told attendees “the only bias I have is that I actually love doing open surgery, but I’m going to try to convince you that there is a potential role for minimally invasive surgery in the future for selected patients with ovarian cancer after neoadjuvant chemotherapy.”

He noted that several studies have convincingly shown that neoadjuvant chemotherapy does not adversely affect oncologic outcomes for patients with advanced-stage ovarian cancer, and decreases perioperative morbidity in patients who receive it, including reductions in serious adverse events, risk of stoma, and 30-day postoperative mortality.

In addition, low use of neoadjuvant chemotherapy is associated with increased risks for 90-day postoperative deaths in both low- and high surgical volume centers in the US, according to unpublished National Cancer Database data.

Dr. Rauh-Hain noted that neoadjuvant chemotherapy use has steadily increased from 2010 through 2020, and added that in 2022, 32% of interval cytoreductive surgeries in the United States were performed with a minimally invasive approach.

To get a better handle on the MIS vs. open-surgery question, Dr. Rauh-Hain and colleagues at MD Anderson and 13 other centers in the United States, Canada, and Europe are currently recruiting patients for the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial. In this phase 3 noninferiority study, patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who have complete or partial responses and CA125 normalization after three or four cycles of neoadjuvant chemotherapy will be randomized to laparotomy or MIS, followed by adjuvant platinum- and taxane-based chemotherapy.

The study by Hayek et al. was internally supported. Dr. Hayek and Dr. Roche reported having no conflicts of interest. Dr. Rauh-Hain disclosed financial relationships with Guidepoint Consulting, and the Schlesinger Group.

Minimally invasive cytoreductive surgery for epithelial ovarian cancer appears to be safe and does not compromise survival, compared with open surgery, when patients have completely resected tumors.

This was a finding of a retrospective study presented by Judy Hayek, MD, during an oral abstract session at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, in San Diego.

Among 2,412 women in the National Cancer Database with tumor-free surgical margins (R0 resections) after interval debulking surgery (IDS), the median overall survival (OS) was 46 months for those who had undergone an open procedure or minimally invasive surgery (MIS) that was converted to an open procedure. In contrast, the median OS was 51 months for patients who underwent laparoscopic or robot-assisted minimally invasive surgery, reported Dr. Hayek, a gynecologic oncology fellow at SUNY Downstate Health Sciences University in Brooklyn, New York.

“R0 resection at the time of interval debulking surgery has similar survival outcomes by minimally invasive surgery versus laparotomy, while R0 resection via laparotomy is associated with higher perioperative mortality. There is no interaction between the extent of surgery and the impact of MIS on survival,” she said during her presentation.

The session included a debate on the pros and cons of minimally invasive vs. open surgery in this population.
 

Growing Use of MIS

Over the last decade, minimally invasive surgery for interval debulking was shown to be safe and feasible. More recently, two studies using National Cancer Database cohorts showed that survival was similar and perioperative outcomes were better with a minimally invasive approach at the time of IDS for patients with early disease, Dr. Hayek said (Obstet Gynecol 2017 Jul;130(1):71-79; and Gynecol Oncol 2023 May:172:130-137).

Potential limitations of MIS include the absence of haptic feedback compared with open surgery, and the possibility that limited visualization of the surgical field could lead to missed residual disease and subsequent poor outcomes for patients who were presumed to have complete gross resections, she said.

For early-stage cervical cancer, non-radical surgery (simple hysterectomy or cone biopsy plus pelvic lymphadenectomy) appears safe with no lasting negative impact on quality of life, according to results of the GOG-278 trial.

In fact, patients’ quality of life was improved after surgery in both groups, and their concerns about cancer recurrence decreased, especially for those undergoing simple hysterectomy, said Allan Covens, MD, in his late-breaking abstract presentation at the Society of Gynecologic Oncology (SGO)’s Annual Meeting on Women’s Cancer. 

“Cone biopsy patients reported less concerns about reproductive fertility after surgery and over time compared to preop assessments,” he added.

Due to screening in developed countries, a large proportion of cervical cancers are discovered at an early stage. Treatment of these cancers with radical surgery is associated with high cure rates but significant adverse effects on quality of life, said Dr. Covens, who is with the University of Toronto, Toronto, Ontario, Canada.

He and his colleagues wanted to see if non-radical surgery could be safely used instead. “Multiple case series have indicated that non-radical surgery is associated with less morbidity and improved quality of life,” he explained. “If this can be proven in a prospective evaluation, it will change future practice.”

GOG-278 was a prospective cohort study of women with stage IA1 (lymph-vascular space invasion+) and IA2-IB1 (≤ 2 cm) carcinoma of the cervix who underwent non-radical surgery (simple hysterectomy or fertility-preserving cone biopsy) and pelvic lymphadenectomy. Criteria included ≤ 10 mm stromal invasion and negative margins on the final cone biopsy.

The primary objectives were to assess changes in functional outcomes of quality of life (bladder/bowel function, sexual function, cancer worry, and reproductive concerns), using validated instruments. Findings were based on 55 patients who underwent cone biopsy and 113 who underwent simple hysterectomy.

Both simple hysterectomy and cone biopsy were associated with “small” declines in sexual function and bladder/bowel function at 4-6 weeks after surgery, but function “quickly” recovered to baseline by 6 months, Dr. Covens reported.

Twelve patients reported a diagnosis of lymphedema, with a Gynecologic Cancer Lymphedema Questionnaire score change of 4 or higher on at least two consecutive evaluations from baseline. This occurred in six cone biopsy and six simple hysterectomy patients.

In a separate presentation, Dr. Covens reported secondary oncologic outcomes from GOG-278, which suggest that non-radical surgery for early-stage cervical cancer is safe, with low perioperative morbidity, although longer follow-up is needed.

He also reported 16 pregnancies in 15 patients who had undergone cone biopsies; 12 of these were successful, and there were four early pregnancy losses.
 

‘Impressive’ Data

Study discussant Kristin Bixel, MD, with The Ohio State University, Columbus, Ohio, said the data are “impressive” and clearly show that non-radical surgery has “minimal impact on bladder/bowel function, with no long-term differences from baseline.”

She added that the incidence of lymphedema was “honestly significantly lower than what I typically counsel patients about” and wondered if the percentage of patients with lymphedema would increase over time.

Dr. Bixel particularly noted the decrease in cancer worry scores after surgery, as sometimes patients who have less radical procedures fear that this comes with an increased risk for recurrence.

The “growing body of data suggests that less radical surgery is safe and effective for early-stage low-risk cervical cancer and highlights the potential reproductive success,” she concluded.

Funding for the study was provided by grants from NRG Oncology. Dr. Covens had no disclosures. Dr. Bixel has received research funding from the Intuitive Foundation.

Although tubal sterilization is common, especially among those with lower income and education levels, misunderstandings persist about the reversibility of the procedure, and previous studies suggest that many pregnant individuals are not making well-informed decisions, wrote Sonya Borrero, MD, of the University of Pittsburgh, and colleagues.

In a study published in JAMA Network Open, the researchers randomized 350 pregnant individuals with Medicaid insurance to usual care or usual care plus a web-based decision aid in English or Spanish called MyDecision/MiDecisión that included written, audio, and video information about tubal sterilization. The tool also included an interactive table comparing tubal sterilization to other contraceptive options, exercises to clarify patients’ values, knowledge checks, and a final summary report.

The two primary outcomes were knowledge of tubal sterilization based on a 10-question true/false test and decisional conflict about contraceptive choices using the low-literacy Decision Conflict Scale. The participants ranged in age from 21 to 45 years, with a mean age of 29.7 years. Participants were randomized prior to 24 weeks’ gestation, and those in the intervention group completed the intervention immediately using a personal device or a university device in the clinical setting. Further assessments occurred by phone during the third trimester and at 3 months postpartum.

Participants in the decision aid group showed significantly greater knowledge of tubal sterilization compared with controls, with a mean of 76.5% correct responses to the knowledge questions, vs. 55.6% in the control group (P < .001). Decisional conflict scores also were significantly lower in the intervention group compared with controls (mean 12.7 vs. 18.7, P = .002).

The most dramatic knowledge gap related to permanence of tubal sterilization; 90.1% of participants in the intervention group answered correctly that the procedure is not easily reversible, compared to 39.3% of the controls. Similarly, 86.6% of the intervention group responded correctly that the tubes do not “come untied” spontaneously, vs. 33.7% of controls (P < .001 for both).

The findings were limited by several factors including the focus only on pregnant Medicaid patients, the presentation of the decision tool only at a point early in pregnancy, which may have been too soon for some participants to consider tubal sterilization, and a lack of data on long-term satisfaction or regret about tubal sterilization decisions, the researchers noted.

However, the knowledge differences between the intervention and control groups remained significant at the third trimester assessment, they said.

More research is needed in other populations and using other time points, but the current study results suggest that use of the MyDecision/MiDecisión tool in a real-world clinical setting at the actual time of decision-making could improve knowledge and inform patients’ choices, the researchers concluded. Improved patient education also could inform policy decisions about the potential elimination of the 30-day waiting period for sterilization procedures, they said.

The study was supported by the National Institute on Minority Health and Health Disparities. The researchers had no financial conflicts to disclose.

TOPLINE:

Pregnancy weight gain is lower in women with a history of gastric bypass or sleeve gastrectomy than in those without such a history, especially when the interval between surgery and conception is shorter, new data suggest.

METHODOLOGY:

• Using Swedish national registers, researchers investigated the association of pregnancy weight gain with  history in 12,776 pregnancies — 6388 in women with a history of bariatric surgery and 6388 in women without such a history.
• Pregnancies were propensity score matched to patients’ early-pregnancy body mass index (BMI), prepregnancy diabetes, , smoking status, education, height, country of birth, and delivery year.
• Post-gastric bypass pregnancies were matched to post-sleeve gastrectomy pregnancies using the same matching strategy.
• Time from surgery to conception was also assessed.

TAKEAWAY:

• Across all early-pregnancy BMI strata, women with a history of bariatric surgery had lower pregnancy weight gain than matched controls.
• The magnitude of difference was largest for women with normal weight or overweight early-pregnancy BMI status (adjusted mean difference in z score, −0.33), which then decreased stepwise within the  subclasses (−0.21, −0.16, and −0.08 for obesity classes I, II, and III, respectively).
• Pregnancy weight gain did not differ by surgery type, but lower pregnancy weight gain was associated with a shorter surgery-to-conception interval (particularly within 1 year) or lower surgery-to-conception weight loss.

IN PRACTICE:

“The highest proportion of weight gain below the recommendations was found among women with a normal weight status. Hence, clinical attention to women with history of bariatric surgery and a normal weight status in early pregnancy might be warranted,” the authors advised.

The study, with the first author Huiling Xu, MD, MSc, Karolinska Institutet, Stockholm, Sweden, was published online in JAMA Network Open.

LIMITATIONS:

Despite rigorous matching, residual confounding was possible. The sample size was limited for some subgroups, possibly affecting statistical power. Although the study provides an overview of pregnancy outcomes within surgery-to-conception interval and pregnancy weight gain z scores, a more in-depth investigation is needed to understand the associations among bariatric surgery, pregnancy weight gain, and pregnancy outcomes.

DISCLOSURES:

Research for this study was supported by the Swedish Research Council for Health, Working Life and Welfare, and the Swedish Research Council. The authors have no relevant disclosures.

TOPLINE:

Pregnancy weight gain is lower in women with a history of gastric bypass or sleeve gastrectomy than in those without such a history, especially when the interval between surgery and conception is shorter, new data suggest.

METHODOLOGY:

• Using Swedish national registers, researchers investigated the association of pregnancy weight gain with  history in 12,776 pregnancies — 6388 in women with a history of bariatric surgery and 6388 in women without such a history.
• Pregnancies were propensity score matched to patients’ early-pregnancy body mass index (BMI), prepregnancy diabetes, , smoking status, education, height, country of birth, and delivery year.
• Post-gastric bypass pregnancies were matched to post-sleeve gastrectomy pregnancies using the same matching strategy.
• Time from surgery to conception was also assessed.

TAKEAWAY:

• Across all early-pregnancy BMI strata, women with a history of bariatric surgery had lower pregnancy weight gain than matched controls.
• The magnitude of difference was largest for women with normal weight or overweight early-pregnancy BMI status (adjusted mean difference in z score, −0.33), which then decreased stepwise within the  subclasses (−0.21, −0.16, and −0.08 for obesity classes I, II, and III, respectively).

SAN ANTONIO — Women with early breast cancer who have less extensive axillary surgery see no effect on their 10-year rates of locoregional recurrence and mortality than do those who have more extensive surgery, according to findings from a large meta-analysis.

Less extensive surgery also reduced patients’ risk for lymphedema, according to research (abstract GS02-05) presented at the San Antonio Breast Cancer Symposium.

These results, which included data from more than 20,000 women, may “reassure” patients and clinicians that more extensive axillary lymph node dissection “does not improve outcomes in many women with early-stage breast cancer,” said Andrea V. Barrio, MD, a breast surgeon at Memorial Sloan Kettering Cancer Center, New York City, who was not involved in the study.

Gurdeep S. Mannu, DPhil, of the University of Oxford, United Kingdom, who presented the findings at SABCS, explained that the optimal surgical management of the axilla remains uncertain in this patient population. 

To better understand the long-term risks and benefits of more vs less aggressive axillary surgery in early breast cancer, Dr. Mannu and colleagues performed a meta-analysis of 29 randomized trials conducted over six decades, which included data on 20,285 women. The trials compared more vs less extensive axillary surgery as well as axillary surgery vs axillary radiotherapy.

In trials comparing more vs less extensive axillary surgery, researchers found that 83% of locoregional recurrences occurred in the breast or in multiple sites/unspecified locations, and the remaining 17% occurred in isolated axilla or other local recurrences, such as in the supraclavicular fossa or internal mammary chain. 

Those with recurrences in the breast or multiple sites/unspecified locations did not benefit from more extensive surgery, demonstrating similar recurrence rates (RR) (RR for breast, 1.13; 95% CI, 0.92-1.40; RR for other, 0.89; 95% CI, 0.67-1.18).

The group with recurrences in isolated axilla or other local recurrences tended to do better with more extensive surgery (RR, 0.43 and 0.41, respectively).

Overall though, after a median follow-up of 10 years, differences in locoregional recurrence rates at any site did not differ among patients who had more vs less extensive axillary surgery (RR, 0.91; P = .22). This finding held even when restricting the analysis to women with node-positive disease/unknown nodal status (RR, 1.00; P = .98) and for node-negative women (RR, 0.88; P = .15).

Dr. Mannu and colleagues observed similar findings for distant recurrence, breast cancer mortality, and death from any cause.

“But where there was quite a striking difference was in morbidity,” said Dr. Mannu.

To examine rates of lymphedema — the surgical complication that has been “one of the main motivations” for the deescalation trials of the past few decades — the researchers focused on more recent trials, which “are most relevant to women treated today,” Dr. Mannu explained. 

These showed that more extensive axillary surgery was associated with almost 2.5-times the rate of lymphedema compared with less extensive treatment (odds ratio [OR], 2.43).

Finally, the team compared axillary dissection with axillary radiotherapy across five trials and found no significant differences in the treatment approaches in terms of locoregional occurrence, distant recurrence, breast cancer mortality, and death from any cause.

However, once again, a notable difference in rates of lymphedema occurred, with axillary dissection associated with higher rates compared with radiotherapy (OR, 1.79).

This is “probably the largest meta-analysis comparing more vs less axillary surgery,” Dr. Barrio said in an interview. 

“When we have one or two positive sentinel nodes, anywhere from 30%-50% of women will have additional positive lymph nodes that we’re not removing” with less extensive surgery, she explained. This study shows that, even then, this “doesn’t seem to impact on survival.”

This is “likely related to better medical treatment and radiation techniques that can treat that disease just as well as big surgery, but with less lymphedema,” she added. 

Nevertheless, Dr. Barrio believes that there are “situations where we still feel that axillary lymph node dissection is important: in women with advanced cancer, like inflammatory breast cancer, and in women who’ve received chemotherapy upfront, then had surgery, and still have positive nodes after the chemo.”

An intrauterine vacuum-induced hemorrhage control device provided prompt and effective management of bleeding in cases of obstetric hemorrhage, based on data from 800 individuals.

Morbidity and mortality related to postpartum hemorrhage (PPH) are often preventable if caught early, but the persistent rise in PPH-associated morbidity illustrates the need for new and innovative treatments, wrote Dena Goffman, MD, of New York-Presbyterian/Columbia University Irving Medical Center, New York, and colleagues.

Goffman_Dena_NY_web.jpg

The device, known as the Jada System, was cleared by the Food and Drug Administration for management of abnormal postpartum uterine bleeding or postpartum hemorrhage (PPH) in August 2020 and showed safety and effectiveness in a registrational study of 106 patients, the researchers said.

In a postmarket registry medical record review known as RUBY (Treating Abnormal Postpartum Uterine Bleeding or Postpartum Hemorrhage with the Jada System), the researchers examined data collected from Oct. 8, 2020, to March 31, 2022, at 16 centers in the United States. The findings were published in Obstetrics & Gynecology.

The study population included all individuals treated with an intrauterine vacuum-induced hemorrhage control device; of these, 530 were vaginal births and 270 were cesarean births. A total of 94.3% had uterine atony, alone or in conjunction with other causes of bleeding. The median maternal age was 30.3 years; approximately 60% and 53% of patients in the vaginal and cesarean groups were White, and approximately 43% and 49% of patients in the two groups, respectively, were nulliparous.

The median blood loss at the time of device insertion was 1,250 mL in vaginal births and 1,980 mL in cesarean births, and the median time from delivery of the placenta to device insertion was 31 minutes and 108 minutes in the two groups, respectively.

The primary endpoint was treatment success, defined as control of bleeding after device insertion, with no escalation of treatment or recurrence of bleeding after the initial bleeding control and device removal.

Treatment success was achieved in 92.5% of vaginal births and 83.7% of cesarean births, and in 95.8% and 88.2%, respectively, among patients with isolated uterine atony. The median insertion time was 3.1 hours for vaginal births and 4.6 hours for cesarean births.

The safety profile was similar to that in the registrational trial and adverse effects were those expected in patients with PPH, the researchers noted.

A total of 14 SAEs were reported in 13 patients with vaginal births, and 22 SAEs were reported in 21 patients with cesarean births. Of these, three were identified as possibly related to the device or procedure (two cases of endometritis in the vaginal birth group and one case of hemorrhagic shock in the cesarean group); no uterine perforations of deaths were reported during the study.

The study was limited by several factors including the use of data mainly from academic centers, which could limit generalizability, and by the use of a mix of estimated and quantitative reporting of blood loss, the researchers noted. Other limitations include the inability to make direct comparisons to other treatments for PPH.

However, the results confirm the safety and efficacy of the device in a real-world setting and support its use as an important new tool in the management of PPH and reducing maternal morbidity and mortality, they concluded.

Two companies were involved in the study; Alydia Health contributed to the concept, design, and analysis, and Organon contributed to data analysis and reviewed the manuscript.

Dr. Goffman disclosed research support from Organon and Alydia Health, as well as serving as a speaker for Haymarket and PRIME PPH education and for Laborie, participation in the Cooper Surgical Obstetrical Safety Council, and serving as an editor for UpToDate. Several coauthors disclosed relationships with multiple companies including Organon and Alydia Health.

For preventing rejection of cardiac transplants in children, the combination of everolimus and low-dose tacrolimus should now be considered an alternative to mycophenolate mofetil (MMF) plus standard-dose tacrolimus, according to the first phase 3 trial to compare antirejection strategies in the pediatric setting.

Even though MMF and tacrolimus have never been evaluated for pediatric cardiac transplant in a controlled trial, this combination is widely considered a standard based on adult data, said Christopher Almond, MD, a professor of pediatric cardiology at Stanford (Calif.) Medicine.

Everolimus has not been widely used in an antirejection regimen in children following heart transplant in part because of a boxed warning. The warning was added to labeling when this agent was associated with increased infection and increased mortality in adults if given within 3 months of transplant.

In this non-inferiority trial, called TEAMMATE, patients were randomized to the MMF-based or everolimus-based regimen 6 months after transplant.
 

Everolimus- vs. MMF-based antirejection

The study enrolled 210 children and adolescents 21 years of age or younger. The control arm treatment consisted of MMF (660 mg/m² every 12 hours) plus standard dose of tacrolimus (initially 7-10 ng/mL followed at 6 months by 5-8 ng/mL).

In the experimental arm, patients received everolimus (3-8 ng/mL) plus a low dose of tacrolimus (initially 3-5 ng/mL followed at 6 months by 2.5-4.5 ng/mL).

The primary endpoint was score on the major adverse transplant event (MATE-6) tool. Based on gradations of severity, this assigns values for cardiac allograft vasculopathy (CAV), chronic kidney disease (CKD), acute cellular rejection (ACR), antibody-mediated rejection, infection, and posttransplant lymphoproliferative disorder (PTLD).

Thirty months after randomization, the MATE-6 scores were 1.96 in the everolimus group and 2.18 in the MMF group, which conferred the everolimus-based regimen with a numerical but not a significant advantage over the MMF-based regimen. For the goal of noninferiority, the everolimus regimen “met the prespecified safety criterion for success,” Dr. Almond said.
 

Numerical advantage for everolimus on efficacy

The primary efficacy endpoint was the MATE-3 score, which is limited to CAV, CKD, and ACR. Again, the mean score on this metric (0.93 vs. 1.25) was lower on the everolimus-based regimen but not significantly different.

Looking at specific events in the MATE-6 score, the everolimus-based regimen was associated with lower numerical rates of CAV and CKD, but a higher rate of PTLD, Dr. Almond reported.

On the MATE-3 efficacy analysis, the everolimus-based regimen was again associated with lower numerical rates of CAV and CKD but higher rates of ACR.

In terms of adverse events, including those involving the gastrointestinal tract, blood cells, proteinuria, and interstitial lung disease, most did not differ markedly even if many were numerically more common in the MMF-based arm. The exception was aphthous stomatitis, which was more common on everolimus (32% vs. 7%; P < .001). There were more discontinuations for an adverse event in the MMF arm (21% vs. 12%; P < .001).

Other differences included a lower proportion of patients in the everolimus arm with anti-HLA antibodies (17% vs. 30%; P < .05). Total cholesterol levels at the end of the study were lower but not significantly different in the MMF group, while the higher median glomerular filtration rate was higher on everolimus, and this did reach statistical significance (P < .05).

Infection rates overall were similar, but cytomegalovirus (CMV) infection was more common on the MMF-based regimen. The 30% lower rate of CMV infection in the everolimus proved to be potentially clinically meaningful when it was considered in the context of MATE-3. When these two endpoints were combined (MATE-3 and CMV infection as a prespecified secondary endpoint, the difference was statistically significant (P = .03) in favor of the everolimus-based regimen,
 

Study supports safety of everolimus regimen

The take-home message is that the everolimus-based regimen, which “is safe in children and young adults when initiated at 6 months after transplant,” can be considered as an alternative to MFF, Dr. Almond concluded.

However, one of the coauthors of the study, Joseph Rossano, MD, chief of the division of cardiology, Children’s Hospital of Philadelphia, suggested a stronger message.

“These data provide compelling reasons to consider initiation of the combination of everolimus and tacrolimus at 6 months post transplant in pediatric heart transplant recipients,” Dr. Rossano said.

Even though the everolimus-based regimen met the terms of noninferiority overall, patients who received this combination rather than the MMF-based regimen “were less likely to have the combined endpoints of vasculopathy, CKD, rejection and CMV infection. Additionally, they were less likely to make donor specific antibodies,” he said.

He also said that this study challenges the current boxed warning for everolimus. He pointed out that the warning, based on early use of everolimus in adults, does not appear to be an issue for children treated at 6 months.

Early mortality based on infection “was not observed in our study,” he said.

The AHA-invited discussant, Antonio G. Cabrera, MD, division chief of pediatric cardiology, University of Utah, Salt Lake City, drew the same conclusions. Based on the study, the everolimus-based regimen can only be described as noninferior to the MMF-based regimen, but Dr. Cabrera listed the same relative advantages as Dr. Rossano, including better kidney function.

Overall, either regimen might be more appealing based on several variables, but Dr. Cabrera said these data suggest everolimus-based treatment “should be considered” as one of two evidence-based options,

Dr. Almond reported no potential financial conflicts of interest. Dr. Rossano reports financial relationships with Abiomed, Bayer, Cytokinetics, Merck, and Myokardia. Dr. Cabrera reported no potential financial conflicts of interest.

For preventing rejection of cardiac transplants in children, the combination of everolimus and low-dose tacrolimus should now be considered an alternative to mycophenolate mofetil (MMF) plus standard-dose tacrolimus, according to the first phase 3 trial to compare antirejection strategies in the pediatric setting.

Even though MMF and tacrolimus have never been evaluated for pediatric cardiac transplant in a controlled trial, this combination is widely considered a standard based on adult data, said Christopher Almond, MD, a professor of pediatric cardiology at Stanford (Calif.) Medicine.

Everolimus has not been widely used in an antirejection regimen in children following heart transplant in part because of a boxed warning. The warning was added to labeling when this agent was associated with increased infection and increased mortality in adults if given within 3 months of transplant.

In this non-inferiority trial, called TEAMMATE, patients were randomized to the MMF-based or everolimus-based regimen 6 months after transplant.
 

Everolimus- vs. MMF-based antirejection

The study enrolled 210 children and adolescents 21 years of age or younger. The control arm treatment consisted of MMF (660 mg/m² every 12 hours) plus standard dose of tacrolimus (initially 7-10 ng/mL followed at 6 months by 5-8 ng/mL).

In the experimental arm, patients received everolimus (3-8 ng/mL) plus a low dose of tacrolimus (initially 3-5 ng/mL followed at 6 months by 2.5-4.5 ng/mL).

The primary endpoint was score on the major adverse transplant event (MATE-6) tool. Based on gradations of severity, this assigns values for cardiac allograft vasculopathy (CAV), chronic kidney disease (CKD), acute cellular rejection (ACR), antibody-mediated rejection, infection, and posttransplant lymphoproliferative disorder (PTLD).

Thirty months after randomization, the MATE-6 scores were 1.96 in the everolimus group and 2.18 in the MMF group, which conferred the everolimus-based regimen with a numerical but not a significant advantage over the MMF-based regimen. For the goal of noninferiority, the everolimus regimen “met the prespecified safety criterion for success,” Dr. Almond said.
 

Numerical advantage for everolimus on efficacy

The primary efficacy endpoint was the MATE-3 score, which is limited to CAV, CKD, and ACR. Again, the mean score on this metric (0.93 vs. 1.25) was lower on the everolimus-based regimen but not significantly different.

Use of a standard algorithm significantly reduced the time from decision to incision in urgent, unscheduled cesarean deliveries, based on data from more than 600 procedures.

No specific recommended decision-to-incision time exists for cases of unscheduled, nonemergent cesarean deliveries, although a target of 30 minutes is recommended for emergent deliveries, Lina T. Bernal, MD, of Boston University and colleagues wrote.

The researchers developed a quality improvement project in which a multidisciplinary team defined which unscheduled cesarean deliveries should qualify as urgent, and identified a goal of 40 minutes or less for decision-to-incision time in these cases.

“We defined urgent, unscheduled cesarean delivery as cesarean delivery in patients with the following diagnoses: active phase arrest at 6 cm or greater, category II fetal heart rate tracing during labor requiring delivery per the Shields algorithm, but not meeting emergent category III criteria, any unscheduled cesarean delivery complicated by chorioamnionitis, and failed trial of labor after cesarean,” they wrote.

In a study published in Obstetrics & Gynecology, the researchers compared times from decision to incision before and after the implementation of a multidisciplinary algorithm. The study included 199 urgent, unscheduled deliveries in a single center between May 2019 and November 2019, and implementation period with 283 deliveries from December 2019 to September 2020, and a postimplementation period with 160 deliveries between October 2020 and May 2021.

The primary outcome was the mean time from decision to incision; secondary outcomes were neonatal status based on 5-minute Apgar score and quantitative blood loss during delivery.

Overall, the mean decision-to-incision time improved from 88 minutes during the preimplementation period to 50 minutes in the postimplementation period.

For Black non-Hispanic patients, the mean decision-to-incision time improved from 98 minutes during the preimplementation period to 50 minutes in the postimplementation period. Similarly, mean times among Hispanic patients decreased from 84 minutes to 49 minutes during the pre- and postimplementation periods, respectively.

No significant improvement in decision-to-incision time was noted among patients in other racial and ethnic groups.

In cases of cesarean delivery for fetal indications, 5-minute Apgar scores were significantly higher in the postimplementation period compared with the preimplementation period (8.5 vs. 8.8, P < .01).

No significant associations appeared between maternal quantitative blood loss and the implementation of the algorithm across treatment periods.

Over the course of the study, adjustments to the algorithm included clarification of the criteria, streamlined communication, and expanded use of resources. “There are no prior studies regarding the effects of creation of an urgent category on decision-to-incision time or maternal or neonatal outcomes,” the researchers wrote. “As a result of improved outcomes and appreciation of a standardized approach, the urgent cesarean delivery designation has been incorporated into the labor unit work flow.”

The findings were limited by several factors including the retrospective design, use of data from a single medical center, and the inability to address confounding variables such as age, parity, body mass index, time of delivery, and staffing, the researchers noted. Other limitations include a lack of data on measures of maternal morbidity beyond quantitative blood loss and other neonatal morbidities, and lack of data on patient satisfaction.

However, the results support the use of a standard algorithm to successfully reduce decision-to-incision time in urgent and unscheduled cesarean deliveries, and next steps for further improvement of care should identify which patients are most likely to benefit from a more rapid delivery, the researchers concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.
