Management of bowel obstruction in patients with advanced ovarian cancer.

In a retrospective study, 58 patients with bowel obstruction due to advanced ovarian cancer were analysed. In a forward stepwise proportional hazard regression analysis, we looked for factors influencing bowel obstruction-free survival. Patients who presented with bowel obstruction as the first sign of ovarian cancer and those with a longer interval between last cancer treatment and bowel obstruction did better. Patients with ascites did worse. No other independent factors were found. Based on these data, we classified patients into a favourable prognosis group (no previous treatment or interval since last treatment exceeding 6 months; no ascites) and a poor prognosis group (interval since last treatment shorter than 6 months; ascites). Patients from the favourable prognosis group had a median bowel obstruction-free survival of 8 months, compared to 1 month for the poor prognosis group (P < 0.001). Surgery had a marginally significant positive effect on bowel obstruction-free survival when compared to medical treatment in the favourable prognosis group (P = 0.052). Surgery had no effect at all in the poor prognosis patients.
