Abstract

Tyrosine kinase inhibitors (TKIs) have shown to be better for progression-free survival than chemotherapy as the first-line treatment for advanced, non-small cell lung cancer (NSCLC), especially in patients with epidermal growth factor receptor mutation (EGFR M+). This study evaluates under the Thai health system context, cost-effectiveness of (A) the use of platinum doublets for all without EGFR testing, and (B) an EGFR test followed by TKIs or platinum doublets conditional on test results. A decision analysis model was constructed to estimate quality-adjusted life years (QALYs) and total cost for each option. Cancer progression and death were pooled from randomized, controlled trials. Quality of life was obtained from patient interview, using the European Quality-of-Life, 5-Dimension questionnaire. Costs associated with treatment outcomes were derived from patient chart reviews. Combining the EGFR test with each TKI, gefitinib, erlotinib and afatinib if M+ or otherwise platinum doublets, resulted in higher effectiveness than the use of platinum doublets for all by 0.15, 0.19 and 0.21 QALYs, respectively. Among the three TKIs, gefitinib was dominated economically by erlotinib, which incurred an incremental cost-effectiveness r...Continue Reading

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
