[Two cases of ovarian metastasis of colon cancer].
CASE 1: A 45-year-old female underwent sigmoidectomy, simple total hysterectomy and bilateral adnexotomy for sigmoid colon cancer and a right ovarian metastasis in December 2007. As adjuvant chemotherapy, S-1 was conducted for six months. She remains disease-free for 38 months after the surgery. CASE 2: A 61-year-old female underwent simple total hysterectomy and bilateral adnexotomy for bilateral ovarian tumors following the surgery for colon cancer, metastatic liver cancer and gastric cancer in January 2010. As adjuvant chemotherapy, capecitabine was administered seven times. Five months after the last surgery, para-aortic lymph node recurrence was diagnosed. FOLFIRI/panitumumab therapy was maintained. For both of the two cases in immune-staining, CK20 staining was positive, and CK7 staining was negative. Ovarian tumors were diagnosed as metastasis from colon cancer. Ovarian metastasis of colon cancer is a relatively rare event, but a long-term survival case has been reported by multimodality therapy including surgery.
