Purpose. The aim of this study was to analyze clinical and pathological characteristics after oophorectomy for ovarian metastases from colorectal cancer. Methods. Twenty patients undergoing oophorectomy for ovarian metastases from colorectal cancer in our hospital between May 2005 and August 2011 were included in the present study. Results. Fourteen patients (70%) were symptomatic, and the median ovarian tumor size was 12.5cm (range, 4-30), and the median interval from the primary surgery to the diagnosis of metachronous ovarian metastases was 15 months (range, 3-63). The location, differentiation, depth, and status of lymph node metastasis of the primary tumor were left colon/rectum in 75%, well/moderately differentiated adenocarcinoma in 100%, T3/T4 in 90%, and positive in 85% of cases, respectively. Ovarian metastases were bilateral in 7 (35%) and unilateral in 13 (65%) patients. The median survival after colorectal cancer operation was 38 months (range, 11-89), and 7 patients survived beyond 5 years. Conclusion. Oophorectomy should be considered for ovarian metastases from colorectal cancer because it may result in symptom relief and long-term survival.
