Intestinal obstruction in patients with advanced carcinoma of the ovaries treated with combination chemotherapy

An analysis of incidence, risk factors and treatment results of intestinal obstruction caused by carcinoma of the ovaries was performed in 310 consecutive patients with carcinoma of the ovaries, The International Federation of Gynecology and Obstetrics stage IIB to IV, treated with combination chemotherapy. With a median observation time of 46 months, the incidence was 14 per cent and the cumulated risk was estimated to be 26 per cent at five years after treatment was begun. Risk factors were stages IIIB and IV, residual primary tumor size greater than 2 centimeters and presence of intestinal carcinomatosis at primary laparotomy. There was no difference in the survival time between 16 conservatively treated patients and 25 surgically treated patients (a median of 30 and 68 days, respectively, p greater than 0.30). The complication risk of surgical treatment was high (64 per cent), and surgical benefit--defined as survival greater than 60 days with total palliation of intestinal symptoms--was achieved in only 32 per cent.
