Abstract
OBJECTIVES:
The aim of this study was to compare the survival benefits associated with gemcitabine chemotherapy and 5-fluorouracil (5-FU)-based concurrent chemoradiotherapy (CCRT) in locally advanced unresectable pancreatic cancer.
METHODS:
One hundred and thirty-eight locally advanced unresectable pancreatic cancer patients were retrospectively enrolled from January 1995 to January 2005. All cases were histologically proven, and patients received gemcitabine chemotherapy, 5-FU-based CCRT, or supportive care at Seoul National University Hospital.
RESULTS:
Median overall survival was 8.2 months. Twenty-six patients received gemcitabine chemotherapy, 56 patients 5-FU-based CCRT, and 56 patients supportive care. Weight loss and treatment modality were identified as independent prognostic factors by multivariate analysis. Patients in the 5-FU-based CCRT (overall survival, 10.4 months) and gemcitabine chemotherapy (11.3 months) groups showed survival benefit over those received supportive care (6.1 months, P < 0.0001). No grades 3 to 4 toxic adverse effects occurred in either treatment group and no statistical significant survival difference was found between gemcitabine chemotherapy and 5-FU-based CCRT (P = 0.5).
CONCLUSIONS:
Patients with locally advanced pancreatic cancer who received gemcitabine chemotherapy or 5-FU-based CCRT showed better survival than those who received supportive care only. Gemcitabine chemotherapy and 5-FU-based CCRT showed similar survival advantages.
