ABSTRACT

Objective To analyze the factors influencing the prognosis of patients with pancreatic cancer.Methods The clinical data of 276 patients with pancreatic cancer who had been admitted to our department from September 1995 to August 2005 were retrospectively analyzed.Cox regression analysis was used to screen out independent risk factors influencing the prognosis of patients with pancreatic head cancer or pancreatic body and tail cancer,and Kaplan-Meier method to calculate the median survival time.The effects of tumor location on the prognosis were examined by Log-rank and Breslow test.Results Cox regression analysis showed that the diameter of tumor,invasion of the superior mesenteric vessel and treatment method were the independent risk factors influencing the prognosis of patients with pancreatic head cancer;while age,lymphadenectasis and treatment method were the independent risk factors influencing the prognosis of patients with pancreatic body and tail cancer.The median survival time of patients with pancreatic head cancer and pancreatic body and tail cancer after radical resection were 460 days and 480 days,which were significantly longer than 240 days and 200 days of patients who received palliative treatment or gave up treatment.The median survival time of patients with whole pancreatic cancer was 117 days,which was significantly shorter than 330 days of patients with pancreatic head cancer and 300 days of pancreatic body and tail cancer.Conclusions Radieal resection is currently the best choice for pancreatic cancer.The prognosis is poor for patients with pancreatic head cancer(diameter≥4 cm)and invasion of the superior mesenteric vessel.Patients with age≤60 and lymphadenectasis are the factors resulting in poor prognosis of pancreatic body and tail cancer.The prognosis of patients with pancreatic head cancer and pancreatic body and tail cancer are close.Patients with whole pancreatic cancer is in the terminal stage with the worst prognosis.
