Bowel obstruction in patients with ovarian cancer: a search for prognostic factors

Abstract

Patients with concomitant ovarian cancer and bowel obstruction were studied in an effort to find objective prognostic factors predictive of patient outcome. A total of 62 patients were followed from 31 to 354 weeks, and a total of 20 variables were considered in the analyses. At the end of the study 49 patients were dead of their disease, and 13 were alive (six disease free and seven with persistent disease). Survival probabilities of the sample were 79% at 6 weeks, 48% at 20 weeks, and 24% at 104 weeks. Univariate analyses revealed no significant difference in the survival times of medically versus surgically treated patients; age greater than 60 years at diagnosis of cancer, presence of ascites, low serum albumin levels, elevated blood urea nitrogen levels, elevated alkaline phosphatase levels, lack of previous radiotherapy (p less than 0.002 for all), advanced tumor stage, normal/ileus x-ray results, and a short diagnosis to obstruction interval (p less than 0.04 for all) resulted in lower survival probabilities.
