Recent reports have demonstrated an improvement in 5-year actuarial survival of patients with resected ductal adenocarcinoma. The purpose of this study was to determine the factors favoring long-term survival after pancreaticoduodenectomy. Between 1974 and 1995, 75 patients with pancreatic head carcinoma underwent pancreaticoduodenectomy in our department. The overall postoperative mortality rate was 5.3% and morbidity was 24%. Median survival following resection was 17 months. The estimated 1-, 2- and 5-year survival rates were 68%, 46.7% and 18.7%, respectively. Five-year survival was significantly greater for node-negative versus node-positive patients (41.7% vs 7.8%, P<0.001), for smaller (<3 cm) versus larger tumours (33.3% vs 8.8%, P<0.006), and for negative versus positive resection margins (23.3% vs 0, P<0.001). Other factors, including gender, age, and blood transfusion had no significant effect on survival. The multivariate analysis was done using the Cox proportional hazards model to determine independent prognostic determinants of survival. The presence of positive resection margins was the strongest independent predictor of decreased survival. Lymph node metastasis, tumour size>3 cm, and poor histologic differentiation were also independent predictors of poor survival. The most favorable subset consisted in 17 patients who had negative resection margins, negative lymph nodes, and tumor size<3 cm. Their 5-year survival rate was 52.9%.
