Prognostic Value of Oophrectomy in Colorectal Cancer Patients with Ovarian Metastasis

cancer death in women and causes over 4000 deaths annually in Taiwan. The incidence of metastases to the ovaries from colorectal cancer is relative uncommon and estimated to be 3~8%. Most series showed that primary colorectal cancer is the most common nongynecologic malignancy resulting in metastatic tumor to the ovary, though one series in Japan revealed that gastric primaries made up 30% of the metastatic primaries to the ovary, followed by breast (21.6%) and colon (6.7%). When ovarian metastasis is diagnosed, it may be isolated metastatic lesion, part of peritoneal involvement or associated other metastatic lesions. Although there is no definite survival benefit of prophylactic oophrectomy while resection of colorectal cancer, improved overall survival has been reported in oophrectomy for patients with direct invasion to ovary or macroscopic ovarian metastasis with curative intend. This study is aimed to investigate the prognosis of surgical treatment for ovarian metastasis from coloJ Soc Colon Rectal Surgeon (Taiwan) December 2009
