Economic evaluation of bevacizumab in the treatment of non-small cell lung cancer (NSCLC)

BACKGROUND Delivering affordable cancer care is becoming increasingly important. Bevacizumab (BEV) is a costly molecular targeted agent effective for a variety of cancer including lung cancer. The objective of this review is to assess published economic evaluation of BEV in the treatment of non-small cell lung cancer (NSCLC). METHODS A literature search in PubMed, Cochrane, and the Health Technology Assessment reports for English-language publications before February 2012 was performed. Studies were independently screened by two reviewers, and eight publications were included in the review. The results of these eight articles were tabulated and all cost estimates were reported in 2011 US dollars. RESULTS Among the eight articles, three were cost studies and five were cost-effectiveness/utility analysis. For first-line treatment, BEV-containing regimen was reported to be the most costly regimen in one study but cost saving when compared with pemetrexed/cisplatin in another study. When compared with other regimens, BEV-containing regimen was reported to be cost effective in two cost-effectiveness studies (incremental cost-effectiveness ratio [ICER] in the range of US$30,318-US$54,317 per life year) but not cost effective in the other three studies (ICER over US$300,000 per life year). CONCLUSION In this review of economic evaluation of BEV in the treatment of NSCLC, it was found that the literature was not conclusive on the economic benefit of BEV. The role of BEV in other treatment settings for NSCLC was unknown. Further studies, such as clinical trials with adequate power to compare the efficacy between low dose and high dose BEV, potential impact of predictive biomarkers for BEV, and comprehensive economic evaluation will strengthen the current state of knowledge on the economic value of BEV in NSCLC.
