OBJECTIVE: The aim of this cohort study was to investigate the clinical outcome and prognostic factors in patients after resection for ductal adenocarcinoma of the pancreatic head.
METHODS: patients with pancreatic head cancer undergoing curative resection (R0) between 1997 and 2002 were included in this study. Univariate and multivariate analyses were performed to examine factors affecting clinical outcome and recurrence of the cancer.
RESULTS: Surgical procedures consisted of 58 (43.3%) extended pancreaticoduodenectomies (EPD), 47 (35.1%) pancreaticoduodenectomies (PD) and 29 (21.6%) pylorus-preserving pancreaticoduodenectomies (PPPD). The results showed that 81.3% (109/134) of patients had a recurrence during the study period, mainly retroperitoneal combined with distant metastasis (53.7%). The median postoperative survival time was 24.7 months. The 1-, 3- and 5-year overall survival rates for the study population were 67.1%, 38.5% and 17.6%, respectively. Univariate analysis showed that preoperative abdominal and/or back pain, tumor size > 2 cm, lymph node involvement and vascular invasion, and CA19-9 level were all significant predictors for poor survival. Multivariate analysis also showed that preoperative abdominal and/or back pain, tumor size > 2 cm, lymph node involvement and vascular invasion were all significant predictors for poor survival.
CONCLUSION: Our results suggest that preoperative abdominal and/or back pain, tumor size > 2 cm, lymph node involvement and vascular invasion are significant predictors for poor survival in patients with pancreatic head cancer.
