title: Prognostic factors in the operative and palliative treatment of pancreatic cancer.
abstract: Recent studies have emphasized the importance of patient selection for the surgical resection of pancreatic adenocarcinoma based on reproducible prognostic factors. The aim of the study was to investigate the prognostic factors affecting long-term survival in patients with resectable and nonresectable pancreatic cancer and to evaluate their prognostic value. Forty six patients (25 women, 21 men, aged 44-80) with ductal adenocarcinoma of the pancreas were reviewed. Primary tumor size and regional enlargement of lymph nodes was assessed with enhanced CT scan. 13 patients were treated conservatively, 9 with standard Whipple procedure (pancreatoduodenectomy) and 24 - with palliative surgery. Survival probabilities were computed using univariate Kaplan-Meier analysis. Log-rank test was used to compare survival between groups. Overall median survival was 6 months with a 4 years survival of 2.2%. There was no difference in survival time (ST) between patients aged 65 years or younger and older (p=0.71). MeanST in patients after Whipple procedure was 10.3, after palliative surgery - 9.4 and after conservative treatment - 4.4 months (p<0.05). Thirty-day surgical mortality was 9.4%. ST was significantly longer in patients with tumors 3 cm or less of diameter compared with larger ones (p<0.05). Presenting signs and symptoms, like jaundice, diabetes, alkaline phosphatase, aspartate and alanine aminotransferase elevation and history of cholecystectomy did not have any significant impact on survival. The only significant independent factors improving survival were: operative treatment and tumor size smaller than 3 cm.
