Oophorectomy in primary colorectal cancer.

Colorectal cancer is a common cancer affecting women which may metastasize to the ovaries. We present five cases of ovarian metastases requiring surgery and review the debate regarding oophorectomy at the primary resection for colorectal cancer. Although prophylactic oophorectomy has not been proven to affect survival, further surgery for symptomatic ovarian metastases may be avoided and the increased risk of developing primary ovarian cancer is abolished.
