ACOG Strengthens Support for Fallopian Tube Removal to Prevent Ovarian Cancer

The American College of Obstetricians & Gynecologists (ACOG) has strengthened its support for fallopian tube removal during hysterectomy to prevent ovarian cancer. Known as opportunistic bilateral salpingectomy (OBS), this procedure has a strong evidence base showing it can reduce a patient's lifetime risk of ovarian cancer by up to 78%. ACOG's updated guidance represents the most robust recommendations yet, emphasizing the importance of empowering patients through education and evidence-based practice.

Studies have demonstrated the safety and effectiveness of salpingectomy. For instance, a Canadian study involving over 80,000 patients found that those who underwent bilateral salpingectomy during hysterectomy had an 80% lower risk of developing serous ovarian cancer compared to those who had hysterectomy alone. Additionally, only 23.1% of these cases were high-grade serous ovarian cancers, compared to 68.1% in a historical control group.

ACOG's guidance encourages clinicians to recommend salpingectomy to patients who do not wish to have future children and are undergoing non-hysterectomy gynecologic surgeries that involve the peritoneal cavity. It also stresses the importance of cross-specialty collaboration, noting that nongynecologic abdominal or pelvic surgeries may present opportunities for risk-reducing salpingectomy with minimal additional risk.

This guidance aligns with recent recommendations from the European Society of Gynaecological Oncology, which also supports OBS for ovarian cancer prevention based on evidence from 129 published articles.
