Pancreatitis Pathology and Treatment

Malignant ascites (MA) caused by peritoneal carcinomatosis is not uncommon in patients with pancreatic cancer. However, the clinical features and outcomes in these patients remain to be elucidated.Baseline characteristics and overall survival (OS) of consecutive patients with advanced pancreatic cancer who presented with MA were retrospectively evaluated.Of 494 patients with advanced pancreatic cancer, 73 (15%) presented with MA. Patients with synchronous MA (n = 21), compared with those with metachronous MA (n = 52), had better performance status (P = 0.02), smaller amount of ascites (P < 0.01), and higher chance of receiving chemotherapy (57% vs 17%, P < 0.01), and resulted in longer OS (115 vs 42 days, P < 0.01). Overall survival was significantly longer in patients receiving chemotherapy than in those with best supportive care alone (124 vs 50 days, P < 0.01). In a multivariate analysis, chemotherapy was prognostic in addition to performance status, CRP, and small amount of MA; the hazard ratio of chemotherapy was 0.46, compared with best supportive care alone (P = 0.02).Although the prognosis of pancreatic cancer patients with MA remains poor, selected patients may be candidate for chemotherapy, regardless of the timing of appearance of MA.
