We aimed to assess the cost-effectiveness of these adjuvant regimens on resected pancreatic cancer. Methods: A Markov model was established to simulate the disease process of resected pancreatic cancer (relapse-free survival, progressive disease, and death). The efficacy and toxicity profiles were collected from the ESPAC-4 trial. Transition probabilities were calculated based on survival in each group. Cost data were calculated from the perspective of the Chinese healthcare payer. The primary endpoint in the analysis was the incremental cost-effectiveness ratio (ICER), and model uncertainties were explored by one-way sensitivity analysis and probabilistic sensitivity analysis. Results: Our results demonstrated that gemcitabine monotherapy cost $36,028.45 and yielded a survival of 1.02 quality-adjusted life year (QALY), while gemcitabine plus capecitabine cost $46,095.05 and yielded a survival of 1.23 QALY. Therefore, the incremental cost-effectiveness ratio of gemcitabine plus capecitabine vs gemcitabine monotherapy was $45,191.23 which surpassed the willingness-to-pay threshold of $29,291.42 per QALY in China. Conclusion: The gemcitabine monotherapy regimen is more cost-effective compared with gemcitabine plus capecitabine regimen for the patients with postoperative pancreatic cancer from the Chinese societal perspective.
