Prognostic parameters determining survival in pancreatic carcinoma and, in particular, after palliative treatment

Prognosis and outcome of patients with pancreatic carcinoma is poor. The aim of the study was to investigate (I)which factors of medical history and clinical status as well as which laboratory parameters determine survival in pancreatic carcinoma and (2) whether specific data can be used as prognostic parameters or for early diagnosis of pancreatic carcinoma. In total, 287 patients with pancreatic carcinoma were enrolled in the study. In 193 subjects, only palliative treatment was possible. Survival was assessed using univariate survival probability curves by Kaplan-Meier. Comparison of patient groups with regard to survival was achieved using the log-rank test. Multivariate analysis was carried out using the Cox regression model. Overall, 22 factors, showing a significant impact on survival in pancreatic carcinoma were found, e.g., tumor-associated factors such as (I)tumor stage according to the UICC classification including TNM-based staging, grading, tumor site, and vascular infiltration; (2) preoperative habits and signs and symptoms (physical condition, pain, loss of appetite, ethanol consumption); (3) change of laboratory parameters (CA 19-9, bilirubin, prothrombin time, urea, C-reactive protein), and (4) type of intervention (surgical approach, R0/ 1/2 resection). Using multivariate analysis, seven factors (UICC tumor stage and site, surgical intervention including number of resected lymph nodes, chemotherapy, occurence of a carcinoma in relatives, preoperative physical condition, night sweat) were determined. In the 193 patients with palliative treatment, only ten factors (among them UICC tumor stage including the presence of metastases; data from the medical history such as physical condition, loss of appetite, and carcinoma in relatives, and laboratory parameters including prothrombin time, protein content, and aspartate aminotransferase levels) were found to be important. Chemotherapy had the strongest impact on survival which was confirmed by multivariate analysis, followed by tumor stage (UICC) and preoperative appetite. Besides tumor-associated determinants, data from the medical history, and pathological laboratory parameters, the prognosis in pancreatic carcinoma is considerably determined by the treatment such as interventional and/or using antineoplastic agents.
