摘　　要：AIM: To appraise the current evidence for prophylactic oophorectomy in patients undergoing primary curative colorectal cancer resection.METHODS: Occult ovarian metastases may lead to increased mortality, therefore prophylactic oophorectomy may be considered for women undergoing colorectal resection. A systematic review and meta-analysis wasperformed for English language studies from 1994 to 2014(PROSPERO Registry number: CRD42014009340), comparing outcomes following prophylactic oophorectomy(no known ovarian or other metastatic disease at time of surgery) vs no ovarian surgery, synchronous with colorectal resection for malignancy. Outcomes assessed: local recurrence, 5-year mortality, immediate post-operative morbidity and mortality, and rate of distant metastases.RESULTS: Final analysis included 4 studies from the United States, Europe and China, which included 627 patients(210 prophylactic oophorectomy and 417 non-oophorectomy). There was one randomized controlled trials, the remainder being non-randomised cohort studies. The studies were all at high risk of bias according to the Cochrane Collaboration's assessment tool for randomised studies and the NewcastleOttawa Score for the cohort studies. The mean age of patients amongst the studies ranged from 56.5 to 67 years. There were no significant differences between the patients having prophylactic oophorectomy at time of primary colorectal resection compared with patients who did not with respect to local recurrence, 5-year survival and distant metastases. There was no difference in post-operative complications or immediate post-operative mortality between the groups.CONCLUSION: Current evidence does not favour prophylactic oophorectomy for patients without known genetic predisposition. Prophylactic surgery is not associated with additional risk of post-operative complications or death.AIM: To appraise the current evidence for prophylactic oophorectomy in patients undergoing primary curative colorectal cancer resection.METHODS: Occult ovarian metastases may lead to increased mortality, therefore prophylactic oophorectomy may be considered for women undergoing colorectal resection.
