Prognostic Factors for Long-Term Survival in Patients with Ampullary Carcinoma: The Results of a 15-Year Observation Period after Pancreaticoduodenectomy

Introduction. Although ampullary carcinoma has the best prognosis among all periampullary carcinomas, its long-term survival remains low. Prognostic factors are only available for a period of 10 years after pancreaticoduodenectomy. The aim of this retrospective study was to identify factors that influence the long-term patient survival over a 15-year observation period. Methods. From 1992 to 2007, 143 patients with ampullary carcinoma underwent pancreatic resection. 86 patients underwent pylorus-preserving pancreaticoduodenectomy (60%) and 57 patients underwent standard Kausch-Whipple pancreaticoduodenectomy (40%). Results. The overall 1-, 5-, 10-, and 15-year survival rates were 79%, 40%, 24%, and 10%, respectively. Within a mean observation period of 30 (0–205) months, 100 (69%) patients died. Survival analysis showed that positive lymph node involvement (P = 0.001), lymphatic vessel invasion (P = 0.0001), intraoperative administration of packed red blood cells (P = 0.03), an elevated CA 19-9 (P = 0.03), jaundice (P = 0.04), and an impaired patient condition (P = 0.01) are strong negative predictors for a reduced patient survival. Conclusions. Patients with ampullary carcinoma have distinctly better long-term survival than patients with pancreatic adenocarcinoma. Long-term survival depends strongly on lymphatic nodal and vessel involvement. Moreover, a preoperative elevated CA 19-9 proved to be a significant prognostic factor. Adjuvant therapy may be essential in patients with this risk constellation.
