Intestinal metastasis and operation in ovarian cancer: a report on 62 cases.
Among numerous sites of metastasis in ovarian cancer, the most common and serious one is the intestinal tract. However, reports on ovarian malignancy with special reference to intestinal metastasis and its surgical treatment have been few. This paper is a retrospective analysis of cases of ovarian cancer with intestinal metastasis treated at the Peking Union Medical College Hospital. Sixty-two cases of ovarian cancer with intestinal metastatic tumours larger than 2 cm in diameter were treated between January 1982 and October 1987, accounting for 28.2% of a total of 221 cases of ovarian cancer admitted during the same period. Twenty-seven patients were operated on for the first time, 24 were referred from other hospitals where the cancer was considered 'inoperable' during the initial surgery, and 11 were recurrent cases. Of the 62 cases, 51 had epithelial cancer and 11 had germ-cell tumours. Metastasis to the large intestine was observed in all 62 cases, of which the rectosigmoid was involved in 59 (95.2%). Metastasis to the small bowel was observed in 26 cases (41.9%). Superficial or serosal invasion occurred in 40 cases (64.5%), and deep invasion, in which the muscularis or both muscularis and mucosa were involved, occurred in 22 cases. A complete or optimal resection of the intraperitoneal tumours was achieved in 46 cases (74.2%). Resection of metastatic tumours of the intestine was performed in 40 cases, of which a repair of the perforated intestinal wall was required in 19. Resection of the bowel was carried out in 22 cases, and a colostomy was done in 6. Postoperatively, all patients were followed up for at least 6 months. During follow-up, 17 patients (27.4%) survived, 39 died and 6 had recurrent disease. The mean survival time for 17 patients achieving complete remission was 30.3 months. Of these, ten have survived for more than 2 years, and seven for more than 3 years. The survival rate was higher in patients with germ-cell tumours and in those having superficial invasion of the intestinal wall, optimal cytoreduction of tumour and relatively sufficient postoperative chemotherapy. However, only the latter two prognostic factors were found to bear statistical significance. The role and feasibility of bowel surgery in ovarian cancer are discussed.
