Abstract
Objective
The purpose of this study was to investigate the impact of combinational versus sequential gemcitabine and platinum on prognosis of advanced pancreatic cancer.
Methods
Two hundred and three patients with advanced pancreatic cancer were selected. They were divided into GemP (first-line gemcitabine and platinum), Gem-then-P (sequential gemcitabine and platinum), Gem/other (first-line gemcitabine-based therapy without subsequent platinum), and Gem (first-line gemcitabine-based therapy without subsequent systemic therapy) groups. The Kaplan–Meier method and log-rank test were used for survival analyses. Cox regression model and propensity score matching were used for prognostic analyses.
Results
The median survival was 12.5 months [95 % confidence interval (CI), 11.2–13.7] in the GemP group (N = 65), 8.3 months (95 % CI 5.0–11.7) in the Gem-then-P group (N = 35), 11.6 months (95 % CI 4.6–18.5) in the Gem/other group (N = 26), and 4.7 months (95 % CI 3.3–6.0) in the Gem group (N = 77) (P < 0.001). Considering the GemP and Gem-then-P groups, performance status, serum creatinine, and response to first-line treatment were independent prognostic factors for overall survival in the multivariate analysis. No specific factors were identified for predicting the choice between GemP and Gem-then-P.
Conclusions
First-line gemcitabine and platinum-based combinations were not superior to sequential gemcitabine and platinum for overall survival. The best sequence of chemotherapy for advanced pancreatic cancer should be explored in future clinical trials.
