EVALUATION OF SURGICAL MANAGEMENT FOR CANCER OF THE PANCREAS
WITH REFERENCE TO FACTORS Rp AND V

Factors influencing prognosis were evaluated in 71 patients who underwent pancreatectomy for ductal cancer of the head of the pancreas. Fifteen patients had lesions less than 2cm in diameter including four patients with stage 1, and their 4-year survival rate was 25.1%. This suggests that small cancer of the pancreas is not compatible with early cancer.
Prognosis of the patients with curative operation for cancer of the head of the pancreas was mainly affected by retroperitoneal (Rp) and portal vein (V) invasions. The 5-year survival rates in patients with Rp (－) and with V (－) were 30 and 53%, respectively, whereas, the 2-year survival rate in those with Rp (+) or V (+) was 0%. Factors Rp and V were closely related to the perineural and connective tissue invasions.
These results substantiate the concept that extended radical pancreatectomy is an indispensable procedure for cancer of the pancreas. Furthermore, for patients in stages III and IV, and stage II with portal vein invasion, radiotherapy in combination with extended pancreatectomy should be performed to achieve microscopical curative resection of the pancreas.
