[Long-term results after radical resections for pancreatic ductal adenocarcinoma--10 years experience].

INTRODUCTION
Pancreatic ductal adenocarcinoma is the most often and the most malignant type of pancreatic tumor. Effective systemic anticancer treatment is still missing and only radical resection can potentially lead to the life prolongation.


TARGET
Long-term therapeutic outcomes evaluation in patients after radical resections due to the pancreatic ductal adenocarcinoma during the 10 years period.


MATERIAL AND METHODS
Population included 42 patients after resection of pancreas due to ductal adenocarcinoma realized during the period from 1995 to 2005. Therapeutic outcomes including long-term survival in different stages of the disease were compared with data collected from patients with another histological type of periampullar tumor by statistical analysis.


RESULTS
48 radical resections of pancreas due to ductal adenocarcinoma were realized during the 10 years period. Six patients were excluded from the follow up. Median of survival with the minimum 6 months of follow up has reached 14 months and the maximal survival time was 35 months. None of the patients has survived 5 years. Five patients were alive after the end of follow up period. There were no statistical difference in survival when particular disease stages were compared (p = 0.3226). Survival of female patients in this population was statistically lower in comparison to male patients (p = 0.0222). Significantly lower survival of patients with ductal adenocarcinoma in comparison to the patients with other types of carcinoma in periampullar localization was demonstrated (p = 0.0234).


CONCLUSION
Achieved results proved that pancreatic carcinoma is solid tumor with the worst long-term prognosis. Long-term survival in this population did not exceed 35 months and was independent on per-operative staging. Long-term prognosis of ductale adenocarcinoma is significantly worse in comparison to other types of carcinoma in periampullar localization.
