Purpose
Second-line chemotherapy has been shown to benefit patients with advanced gastric cancer (AGC), extending the overall survival (OS) and progression-free survival (PFS). This study aimed to assess the efficacy and cost-effectiveness of second-line treatment for elderly patients with AGC.
Methods
Medical records and follow-up information of elderly patients (≥70 years) with AGC who received second-line chemotherapy were collected. A Markov model comprising three health states PFS, progressive disease and death was developed to simulate the process of AGC. Cost was calculated from the perspective of Chinese society. Sensitivity analyses were applied to explore the impact of essential variables.
Results
Forty-three elderly patients with AGC receiving second-line chemotherapy were included in our study. The median OS was 6.0 months (95% confidence interval (CI) 3.90–8.10) and PFS was 3.1 months (95% CI 1.38–4.82). No treatment-related death occurred. The most frequently drug-related grade 3/4 AEs were diarrhea (2.3%), leukopenia (16.3%) and nausea (7.0%). The incremental cost-effective ratio was $18,223.75/QALY for second-line chemotherapy versus BSC, which was below the threshold of 3× the per capita GDP of China, $23,970.00.
Conclusion
Second-line chemotherapy was an optimal strategy for elderly AGC patients in China from the efficacy and cost-effectiveness perspective.
