 A 52-year-old woman with a chief complaint of abdominal distension was admitted to our hospital with suspected bilateral ovarian cancer. After examining the gastrointestinal tract, a tumor was found in the sigmoid colon, and the patient was diagnosed as having well-differentiated tubular adenocarcinoma by biopsy. Under the circumstances, laparoscopic surgery was performed to identify whether the cancer was metastatic ovarian cancer or double cancer(ovarian cancer and sigmoid colon cancer). The biopsy of peritoneal disseminated lesion showed that the lesion was derived from the primary adenocarcinoma of the ovary, and the patient was conclusively diagnosed as having double cancer. As the prognosis is judged to be dependent upon ovarian cancer based on the disease progression, neoadjuvant chemotherapy for the ovarian cancer was first performed, followed by simultaneous curative surgery for ovarian cancer and sigmoid colon cancer, performed jointly with surgical doctors. Six courses of postoperative adjuvant chemotherapy for the ovarian cancer were then performed, and bevacizumab maintenance therapy is currently in progress.
