OBJECTIVES: The aim of this study was to identify predictors for longterm survival following pancreaticoduodenectomy (PD) for pancreatic and other periampullary adenocarcinomas.
METHODS: Clinicopathological factors were compared between short-term (<5 years) and longterm (≥ 5 years) survival groups. Rates of actual 5-year and actuarial 10-year survival were determined.
RESULTS: There were 109 (21.8%) longterm survivors among a sample of 501 patients. Patients with ampullary adenocarcinoma represented 76.1% of the longterm survivors. Favourable factors for longterm survival included female gender, lack of jaundice, lower blood loss, classical PD, absence of postoperative bleeding or intra-abdominal abscess, non-pancreatic primary cancer, earlier tumour stage, smaller tumour size (≤ 2 cm), curative resection, negative lymph node involvement, well-differentiated tumours, and absence of perineural invasion. Independent factors associated with longterm survival were diagnosis of primary tumour, jaundice, intra-abdominal abscess, tumour stage, tumour size, radicality, lymph node status and cell differentiation. The prognosis was best for ampullary adenocarcinoma, for which the rate of actual 5-year survival was 32.8%, and poorest for pancreatic head adenocarcinoma, for which actual 5-year survival was only 6.5%.
CONCLUSIONS: The majority of longterm survivors after PD for periampullary adenocarcinomas are patients with ampullary adenocarcinoma. The longterm prognosis in pancreatic head adenocarcinoma remains dismal.
