title: Malignant ascites: demographics, therapeutic efficacy and predictors of survival.
abstract: Demographics, treatment patterns, treatment efficacy and clinical predictors of survival were studied in 76 consecutive patients with malignant ascites. Sixty-four percent of patients were female, and mean age was 63 years. The most common primary malignancies were ovarian cancer, carcinoma of unknown primary, breast cancer, colorectal carcinoma and lymphoma. Ascites was present at the time of diagnosis of malignancy in 39%. Diuretics were administered in 22% of patients with a 22% response in ascites; all responding patients had hepatic metastases. Systemic anticancer therapy was administered in 38%, with a 38% objective response in ascites. Five peritoneovenous shunts were placed, with one shunt functional at 2 weeks. Paracentesis was performed in 71% of patients with complications potentially due to paracentesis occurring in 24% of these patients. Median survival was 78 days from the clinical diagnosis of ascites. Multivariate analysis revealed significantly shortened survival in patients with liver metastases and elevated serum bilirubin, while ovarian cancer was a significant independent predictor of prolonged survival.
