  • BACKGROUND: Women with Lynch syndrome who have completed childbearing should be offered prophylactic hysterectomy and bilateral salpingo-oophorectomy for gynecologic cancer prevention. The benefit of prophylactic gynecologic surgery at the time of colon cancer resection is unclear.OBJECTIVE: This study aimed to compare the cost, quality of life, and likelihood of being alive and free from colon, endometrial, and ovarian cancer between operative choices for patients with Lynch syndrome undergoing surgery for colon cancer.DESIGN: A Markov decision tree spanning 40 years was constructed for a hypothetical cohort of 30-year-old women with Lynch syndrome who had been diagnosed with colon cancer. Outcomes of 6 surgical strategies were compared, including segmental or total abdominal colectomy with or without hysterectomy alone or combined with bilateral salpingo-oophorectomy.SETTINGS: A Markov cost-effectiveness analysis was performed at a single center.PATIENTS: A literature search was performed identifying studies of patients with genetically diagnosed Lynch syndrome that described cost, risk of mortality, and quality of life after colon cancer resection and prophylactic gynecologic surgery.MAIN OUTCOME MEASURES: The primary outcomes measured were quality-adjusted life-years and the likelihood of being alive and free from colon, endometrial, and ovarian cancer 40 years after surgery.RESULTS: Women with Lynch syndrome who underwent a total abdominal colectomy and hysterectomy with bilateral salpingo-oophorectomy had the highest likelihood of being alive and cancer free. Total abdominal colectomy with hysterectomy was a close second, but yielded the largest amount of quality-adjusted life-years and lowest cost.LIMITATIONS: This study is limited by the statistical method and quality of studies used.CONCLUSIONS: Total abdominal colectomy with prophylactic hysterectomy at 30 years of age was the most cost-effective surgical choice in women with Lynch syndrome and colon cancer. The addition of bilateral salpingo-oophorectomy offered the highest event-free survival and lowest mortality. However, the additional morbidity of premature menopause of prophylactic salpingo-oophorectomy for younger women outweighed the benefit of ovarian cancer prevention.
