The authors, in the period from Jan. 1980 to Dec. 1990, observed 67 patients with tumor located in the head of pancreas and 27 patient with periampullary tumors. These included 18 tumors originated from the ampulla of Vater and 9 from distal common bile duct. Operability rate ranged from 62.6% pancreatic carcinoma to 94.4% tumors of ampulla, according to the tumor location. Resectability rate ranged from 9.5% for pancreatic adenocarcinoma for 94.1% to ampullary tumors. Considering 23 resections, 18 were pancreatoduodenectomies and 5 local excisions for tumor of ampulla. Mortality was 7.7% after non resectional treatment and two patients (8.7%) died in the immediate postoperative period after radical resection. Multivariate analysis on all patients operated (n. 65) revealed that 5 years survival rate was significantly related to intent of operation (palliative = 0 - curative = 8.6%), histologic type, and site. In fact no patient with pancreatic adenocarcinoma achieved a 5 years survival rate. Two patients with adenocarcinoma of ampulla survived 5 years. Cancer of the head of pancreas is quite malignant because, owing to pancreas position, an early diagnosis is very hard. Most times resective surgical treatment is impossible because of the cancer diffusion.
