Abstract

INTRODUCTION:

Pancreatic cancer has a poor prognosis with <5% alive at 5 years, despite active surgical treatment. The study aim was to review patients undergoing pancreatic resection and assess the effect of clinical and pathological parameters on survival.

PATIENTS AND METHODS:

All patients who had undergone radical pancreatic surgery, January 1996 to December 2008, were identified from the unit database. Additional information was retrieved from the patient records. The demographic, clinical, and pathological records were recorded using Microsoft Excel. Survival was assessed using Kaplan-Meier and predictors of survival determined by multinominal logistic regression and log rank test.

RESULTS:

126 patients were identified from the database. The majority (106) had a Whipple's procedure, 14 had a distal pancreatectomy and 6 had local periampullary excision. The average age of the Whipple's group of patients was 61.7 years (± 11.7) with most procedures performed for malignancy (n=100). Survival was worse with adenocarcinoma compared to all other pathologies (p=0.013), while periampullary tumours had a better prognosis compared to other locations (p=0.019). Survival decreased with poorer differentiation (p=0.001), increasing pT (p<0.001) and pN stage (p<0.001). Survival was worse with perineural (p=0.04) or lymphovascular invasion (p=0.05). A microscopic postive resection margin (R1) was associated with a worse survival (p=0.007). Tumour differentiation (p=0.001) and positive nodal status (p<0.001) were found to be independent predictors of mortality.

CONCLUSION:

Tumour differentiation and nodal status are important predictors of outcome. A positive resection margin is associated with a poorer survival.
