Cost-Effectiveness Analysis of Treatments for Metastatic Pancreatic Cancer Based on Prodige and MPACT Trials

Abstract

PURPOSE: Fluorouracil, leucovorin, irinotecan, oxaliplatin (FOLFIRINOX) and gemcitabine plus nab-paclitaxel (GEM-N) have shown a significant survival benefit for the treatment of metastatic pancreatic cancer. The objective of this study was to assess the cost-effectiveness of FOLFIRINOX versus GEM-N for treating metastatic pancreatic cancer based on the PRODIGE and MPACT trials. METHODS: A decision model was performed to compare FOLFIRINOX with GEM-N. Primary base case data were identified from PRODIGE and MPACT trials. Costs were estimated and incremental cost-effectiveness ratio (ICER) was calculated at West China Hospital, Sichuan University, China. Survival benefits were reported in quality-adjusted life-years (QALY). Finally, sensitive analysis was performed by varying potentially modifiable parameters in the model. RESULTS: The base-case analysis showed that FOLFIRINOX cost $37,203.75 and yielded a survival of 0.67 QALY, and GEM-N cost $32,080.59 and yielded a survival of 0.51 QALY in the entire treatment. Thus, the ICER of FOLFIRINOX versus GEM-N was $32,019.75 per QALY gained. CONCLUSIONS: The GEM-N regimen was more cost-effective compared with the FOLFIRINOX regimen for the treatment of metastatic pancreatic cancer from a Chinese perspective.
