Ovarian Cancer Prevention: Why Routine Surgeries May Hold the Key to Reducing Risk
Nearly half of women diagnosed with high-grade serous ovarian cancer (HGSC) may have missed crucial opportunities for preventative measures, according to new research published in JAMA Surgery. This isn’t about a failure in healthcare, but a rapidly evolving understanding of the disease – and a potential shift towards proactively addressing risk during common surgical procedures.
The Missed Window: Salpingectomy and Beyond
The study, led by Dr. Sara Moufarrij of Memorial Sloan Kettering Cancer Center, retrospectively analyzed over 1,800 patients and found a significant number had prior surgeries – like tubal ligations, hysterectomies, or even hernia repairs – where a salpingectomy (removal of the fallopian tubes) could have been performed. Why is this important? Increasingly, research points to the fallopian tubes as the origin of many HGSCs, not the ovaries themselves. Removing the tubes reduces the risk, even if the ovaries are retained.
Specifically, 54.2% of patients with missed opportunities had undergone tubal ligation/hysterectomy, procedures where salpingectomy could have been easily added. Another 45.8% had other abdominal surgeries where the opportunity presented itself, particularly in women over 45. This highlights a critical gap: current guidelines don’t universally recommend routine salpingectomy during these procedures, even though the potential benefit is substantial.
Genetic Testing: A Parallel Opportunity
The study also revealed a concerning trend in genetic testing. Among patients with a family history of ovarian cancer – a key indicator of increased risk – over 43% missed the opportunity for germline genetic testing and subsequent risk-reducing surgery. This underscores the need for improved family history screening and proactive referral for genetic counseling. Identifying genetic predispositions like BRCA mutations allows for informed decisions about preventative options, including prophylactic salpingo-oophorectomy (removal of both tubes and ovaries).
The Rise of Targeted Prevention and Polygenic Risk Scores
The future of ovarian cancer prevention isn’t about blanket recommendations, but about personalized risk assessment. As the authors of the study note, we’re moving towards a model of “targeted salpingectomy” based on polygenic risk modeling. What does this mean?
Polygenic risk scores (PRS) analyze thousands of genetic variants to estimate an individual’s overall risk of developing the disease. Combined with family history and other risk factors, PRS can help identify women who would benefit most from preventative surgery. This approach avoids unnecessary surgeries for those at low risk while ensuring those at higher risk receive appropriate intervention.
The Role of Opportunistic Salpingectomy
While PRS are still evolving, the concept of opportunistic salpingectomy – performing the procedure during other abdominal surgeries – is gaining traction. This approach is cost-effective and minimizes the need for separate surgical procedures. However, widespread adoption requires increased awareness among surgeons and clear guidelines for implementation.
Implications for Patients and Healthcare Providers
This research has significant implications for both patients and healthcare providers. Patients should proactively discuss their family history and risk factors with their doctors. If undergoing abdominal surgery, they should specifically ask about the possibility of adding a salpingectomy. Healthcare providers need to stay informed about the latest research on ovarian cancer prevention and incorporate risk assessment into routine care.
The conversation needs to shift from simply treating ovarian cancer to actively preventing it. By leveraging advancements in genetics and embracing a more proactive approach to surgical prevention, we can significantly reduce the burden of this devastating disease.
