Preventing Ovarian Cancer: A quarter of Cases Could Be Avoided Through Concurrent Salpingectomy
october 27, 2023
A startling revelation in gynecologic oncology suggests that a significant portion of high-grade serous carcinoma (HGSC) cases, commonly known as ovarian cancer, might have been preventable. New research indicates that nearly one-fourth of patients diagnosed with this aggressive cancer could have potentially avoided it if they had undergone a concurrent salpingectomy-the removal of the fallopian tubes-during an unrelated abdominal surgery. This finding underscores a critical missed opportunity in cancer prevention strategies for women.
Opportunistic Salpingectomy: A proactive Approach
The concept of performing a salpingectomy as a prophylactic measure, particularly in women with an average lifetime risk of ovarian cancer, is gaining traction. This surgical option is being explored for individuals undergoing other elective abdominal procedures. The study identified “missed opportunities” as instances where a salpingectomy was not performed, either during procedures leading to permanent sterilization like bilateral tubal ligation or hysterectomy, or during other abdomino-pelvic surgeries for patients aged 45 and older, at least a year before their HGSC diagnosis.
Analysis of nearly 1,900 patients with HGSC revealed that 23.7% experienced such missed preventive opportunities. A substantial majority of these patients (over 54%) had undergone procedures for permanent contraception. The remaining nearly half had other abdominal surgeries, including common procedures like gall bladder removal, hernia repair, and bowel surgeries.
Furthermore, the research highlighted disparities in preventative care among women with a family history of ovarian cancer. Among these individuals,a concerning 43.2% missed the chance for genetic testing and risk-reducing surgery.
An accompanying survey of patients with HGSC reinforced these findings. Out of 348 respondents from a national ovarian cancer organization, 15.5% reported having a missed opportunity for a salpingectomy.
“Addressing the full spectrum of missed opportunities is crucial for eradicating HGSC, especially given the lack of effective screening and limited treatment options,” stated the study’s lead author, Dr. Sara Moufarrij, a gynecologic oncology fellow at Memorial Sloan Kettering Cancer Center. Her team emphasized that maximizing these preventive interventions is key.
Understanding the Scope and Patient Profiles
The retrospective study examined data from 1,877 patients diagnosed with HGSC between june 2015 and June 2021 at major medical centers. The median age of diagnosis was 64 years, with the cohort predominantly being White, followed by Black and Asian American and Pacific Islander individuals. A significant 89.7% of cases were diagnosed at late stages (FIGO stage III or IV), underscoring the aggressive nature of the cancer and the importance of early detection and prevention.
A notable percentage of patients (12%) had no documented genetic testing for mutations like BRCA1 and BRCA2, which are strongly associated with ovarian cancer risk. Among those tested, percentages of mutations were as follows:
| Genetic Mutation | Percentage of Patients |
|---|---|
| BRCA1 | 11% |
| BRCA2 | 6% |
| ATM | 9% |
| Mixed Mutations | 14% |
| Other Unspecified Mutations | 14% |
| Negative BRCA1/2 & No Test | 69% |
The study also noted that 34.3% of the patients had passed away by the time the data was collected, highlighting the lethality of advanced-stage HGSC.
Moving Forward: Strategies for Prevention
The researchers propose the development of a risk-assessment algorithm to help prioritize salpingectomy in appropriate patients. This algorithm could guide clinicians in identifying individuals who would benefit most from this preventive surgery.
“High-risk patients due to genetic susceptibility should be counseled and managed according to established guidelines,” the authors recommended. They further advised individualized counseling for patients with a family history of ovarian cancer, even with negative genetic tests, suggesting stand-alone salpingectomy as a risk-reducing strategy. for those considered average risk, maximizing the opportunity for opportunistic salpingectomy during other indicated operations, particularly after reproductive years, is encouraged.
Did You Know? High-grade serous carcinoma (HGSC) originates most frequently enough in the fallopian tubes, making salpingectomy a direct preventive measure.
Pro Tip: Discuss your family history of gynecologic cancers with your doctor to assess your personal risk and explore potential preventive options.

The Path to Ovarian Cancer Eradication
The findings from this extensive analysis offer a critical roadmap for enhancing ovarian cancer prevention efforts. By recognizing and acting upon “missed opportunities” for salpingectomy, healthcare providers can significantly impact the incidence of HGSC. Continued research and implementation of these preventive strategies, coupled with increased awareness and patient education, hold the potential to drastically reduce the burden of this devastating disease.
