Salpingectomy for the Risk Reduction of Ovarian Cancer: Is It Time for a Salpingectomy-alone Approach?

ABSTRACT:

Objective

To summarize published evidence supporting current strategies for the prevention of epithelial ovarian cancer in women with a genetic, elevated risk for the development of this disease, as well as the emerging data on the novel salpingectomy with delayed oophorectomy (SDO) strategy. Furthermore, we will explore whether salpingectomy alone is a viable risk-reducing strategy for these women. We will also discuss current national guidelines for risk-reducing surgery based on patients' individual genetic predisposition.

Data sources

MEDLINE, PubMed, EMBASE, and the Cochrane Database, with a focus on randomized controlled trials and large prospective, observational studies.

Methods of study selection

The key search terms for our review included Medical Subject Headings: "salpingectomy," "ovarian cancer," and "risk-reducing surgery."

Tabulation, integration, and results

The fallopian tube is now well established as the site of origin for most ovarian cancers, particularly high-grade serous carcinomas. This finding has led to the development of new preventive surgical techniques, such as SDO, which may be associated with fewer side effects. However, until the results of ongoing trials are reported and the impact of SDO on ovarian cancer risk reduction is established, it should not be recommended outside of clinical trials, and bilateral salpingo-oophorectomy remains the treatment of choice for risk-reducing surgery, especially in women with a genetic, high risk for ovarian cancer.

Conclusion

The decision to undergo risk-reducing surgery among women with an elevated risk for ovarian cancer should be made after comprehensive consultation and individually based on genetic predisposition, childbearing status, and personal preference.

Project description:BackgroundOvarian cancer is the leading cause of death among gynaecological cancers. The identification of the fallopian tube epithelium as the origin of most ovarian cancers introduces a novel prevention strategy by removing the fallopian tubes during an already indicated abdominal surgery for another reason, also known as an opportunistic salpingectomy. This preventive opportunity is evidence based, recommended and established at the time of gynaecologic surgery in many countries worldwide. To expand interest among surgeons in performing a salpingectomy during non-gynaecological surgery, the aim of this review is to identify knowledge gaps during those surgeries.MethodsA scoping review was performed following the PRISMA-Scoping Review (ScR) checklist. PubMed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL) database and Cochrane Library were systematically searched from inception to November 2024. Trial registers were searched for ongoing trials. All studies reporting original data on salpingectomy during non-gynaecological surgery were included. Outcomes were provided narratively.ResultsEighteen studies were identified reporting on the implementation, surgical feasibility, patients' perspectives, physicians' knowledge and cost-effectiveness of an opportunistic salpingectomy during non-gynaecological surgery. Population-level data indicate that an opportunistic salpingectomy is rarely performed in non-gynaecological surgeries. High success rates and no complications of an opportunistic salpingectomy were observed during bariatric surgery and cholecystectomies. However, performing an additional salpingectomy appeared more time-consuming. Patients had strong interest in information on and willingness to undergo opportunistic salpingectomy. Cost-effectiveness analysis encourages opportunistic salpingectomy use, as models show reduced ovarian cancer incidence and mortality rate while being cost-effective.ConclusionsOpportunistic salpingectomy during non-gynaecologic surgery appears to be a promising method to prevent ovarian cancer. Implementing such a strategy will require education of multiple surgical disciplines, training and resolution of organizational issues.

Project description:Evidence suggesting that high-grade serous ovarian cancers originate in the fallopian tubes has led to the emergence of opportunistic salpingectomy (OS) as an approach to reduce ovarian-cancer risk. In the U.S., some national societies now recommend OS in place of tubal ligation for sterilization or during a benign hysterectomy in average-risk women. However, limited data exist on the dissemination of OS in clinical practice. We examined the uptake and predictors of OS in a nationwide sample of inpatient and outpatient claims (N = 48,231,235) from 2010 to 2017. Incidence rates of OS were calculated, and an interrupted time-series analysis was used to quantify changes in rates before (2010-2013) and after (2015-2017) national guideline release. Predictors of OS use were examined using Poisson regression. From 2010 to 2017, the age-adjusted incidence rate of OS for sterilization and OS during hysterectomy increased 17.8-fold [95% confidence interval (CI), 16.2-19.5] and 7.6-fold (95% CI, 5.5-10.4), respectively. The rapid increase (age-adjusted increase in quarterly rates of between 109% and 250%) coincided with the time of national guideline release. In multivariable-adjusted analyses, OS use was more common in young women and varied significantly by geographic region, rurality, family history/genetic susceptibility, surgical indication, inpatient/outpatient setting, and underlying comorbidities. Similar differences in OS uptake were noted in analyses limited to women with a family history/genetic susceptibility to breast/ovarian cancer. Our results highlight significant differences in OS uptake in both high- and average-risk women. Defining subsets of women who would benefit most from OS and identifying barriers to equitable OS uptake is needed. PREVENTION RELEVANCE: Opportunistic salpingectomy for ovarian-cancer risk reduction has been rapidly adopted in the U.S., with significant variation in uptake by demographic and clinical factors. Studies examining barriers to opportunistic salpingectomy access and the long-term effectiveness and potential adverse effects of opportunistic salpingectomy are needed.

Project description:ImportanceA body of pathological and clinical evidence supports the position that the fallopian tube is the site of origin for a large proportion of high-grade serous ovarian cancers. Consequently, salpingectomy is now considered for permanent contraception (in lieu of tubal ligation) or ovarian cancer prevention (performed opportunistically at the time of surgical procedures for benign gynecologic conditions).ObjectiveTo evaluate the association between salpingectomy and the risk of invasive epithelial ovarian, fallopian tube, and peritoneal cancer.Design, setting, and participantsThis population-based retrospective cohort study included all women aged 18 to 80 years who were eligible for health care services in Ontario, Canada. Participants were identified using administrative health databases from Ontario between January 1, 1992, and December 31, 2019. A total of 131 516 women were included in the primary (matched) analysis. Women were followed up until December 31, 2021.ExposuresSalpingectomy (with and without hysterectomy) vs no pelvic procedure (control condition) among women in the general population.Main outcomes and measuresWomen with a unilateral or bilateral salpingectomy in Ontario between April 1, 1992, and December 31, 2019, were matched 1:3 to women with no pelvic procedure from the general population. Cox proportional hazards regression models were used to estimate the hazard ratios (HRs) and 95% CIs for ovarian, fallopian tube, and peritoneal cancer combined.ResultsAmong 131 516 women (mean [SD] age, 42.2 [7.6] years), 32 879 underwent a unilateral or bilateral salpingectomy, and 98 637 did not undergo a pelvic procedure. After a mean (range) follow-up of 7.4 (0-29.2) years in the salpingectomy group and 7.5 (0-29.2) years in the nonsurgical control group, there were 31 incident cancers (0.09%) and 117 incident cancers (0.12%), respectively (HR, 0.82; 95% CI, 0.55-1.21). The HR for cancer incidence was 0.87 (95% CI, 0.53-1.44) when comparing those with salpingectomy vs those with hysterectomy alone.Conclusions and relevanceIn this cohort study, no association was found between salpingectomy and the risk of ovarian cancer; however, this observation was based on few incident cases and a relatively short follow-up time. Studies with additional years of follow-up are necessary to define the true level of potential risk reduction with salpingectomy, although longer follow-up will also be a challenge unless collaborative efforts that pool data are undertaken.

Project description:ImportanceOpportunistic salpingectomy (OS), which is the removal of fallopian tubes during hysterectomy or instead of tubal ligation without removal of ovaries, is recommended to prevent ovarian cancer, particularly serous ovarian cancer. However, the effectiveness of OS is still undetermined.ObjectiveTo examine observed vs expected rates of ovarian cancer among individuals who have undergone OS.Design, setting, and participantsThis is a population-based, retrospective cohort study of all individuals in British Columbia, Canada, who underwent OS or a control surgery (hysterectomy alone or tubal ligation) between 2008 and 2017, with follow-up until December 31, 2017. Those with any gynecological cancer diagnosed before or within 6 months of their procedure were excluded. Data analysis was performed from April to August 2021.ExposuresRemoval of both fallopian tubes at the time of hysterectomy or instead of tubal ligation while leaving ovaries intact.Main outcomes and measuresAn ovarian cancer diagnosis listed in the British Columbia Cancer Registry. Age-specific rates of epithelial and serous ovarian cancer in the control group were combined with the specific follow-up time in the OS group to calculate expected numbers (and 95% CIs) of ovarian cancers in the OS group. These were compared with observed numbers. Age-adjusted expected and observed numbers of breast and colorectal cancers were also examined in the OS group.ResultsThere were 25 889 individuals who underwent OS (mean [SD] age, 40.2 [7.1] years; median [IQR] follow-up, 3.2 [1.6-5.1] years) and 32 080 who underwent hysterectomy alone or tubal ligation (mean [SD] age, 38.2 [7.9] years; median [IQR] follow-up, 7.3 [4.6-8.7] years). There were no serous ovarian cancers in the OS group and 5 or fewer epithelial ovarian cancers. The age-adjusted expected number was 5.27 (95% CI, 1.78-19.29) serous cancers and 8.68 (95% CI, 3.36-26.58) epithelial ovarian cancers. Age-adjusted expected vs observed numbers of breast cancers (22.1 expected vs 23 observed) and colorectal cancers (9.35 expected vs 8 observed) were not significantly different.Conclusions and relevanceIn this cohort study, the OS group had significantly fewer serous and epithelial ovarian cancers than were expected according to the rate at which they arose in the control group. These findings suggest that OS is associated with reduced ovarian cancer risk.
