A Trial-Based Cost-Effectiveness Analysis of Bevacizumab and Chemotherapy Versus Chemotherapy Alone for Advanced Nonsquamous Non–Small-Cell Lung Cancer in China



The first-line bevacizumab plus chemotherapy resulted in a clinical efficacy for Chinese patients with advanced nonsquamous non–small-cell lung cancer (NSCLC). Some economic analyses have carried out various methods to evaluate the cost-effectiveness of bevacizumab as the first-line treatment for NSCLC in other countries. Our objective was to assess the cost-effectiveness of bevacizumab plus chemotherapy compared with chemotherapy alone for the first-line treatment of advanced nonsquamous NSCLC.


A Markov model was applied from the perspective of the Chinese health care system to assess cost-effectiveness. It was based on the clinical trial BEYOND that compared bevacizumab plus carboplatin/paclitaxel (B+CP) with placebo plus carboplatin and paclitaxel (PI+CP) for advanced nonsquamous NSCLC. Ten-year quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs) were calculated. One-way sensitivity analysis and probabilistic sensitivity analyses (PSA) were performed.


QALYs were 1.17 years in the B+CP group and 0.83 years in the PI+CP group, resulting in a difference of 0.34 years. The ICER was $130,937.09/QALY, which was far beyond the willing-to-pay threshold of $24,314/QALY. At a threshold of $130,584/QALY, addition of bevacizumab had a 50% probability of being cost-effective.


Bevacizumab is not cost-effective when combined with chemotherapy for patients with advanced nonsquamous NSCLC based on the Chinese health care system, resulting in a less demand in the Chinese market.
