Abstract

INTRODUCTION:

The survival effectiveness of neoadjuvant chemotherapy in non-small cell lung cancer (NSCLC) is still unclear based on the study of most up-to-date literatures. This article contributes to this problem by conducting an updated meta-analysis.

METHODS:

Based on Burdett et al's (J Thorac Oncol 2006;1:611-621) systematic review, this meta-analysis was conducted. Articles were searched electrically. The possible survival benefit of neoadjuvant chemotherapy was assessed by hazard ratio (HR) in terms of overall survival. A subgroup meta-analysis with only stage III NSCLC was also conducted. The software of Review Manager was used for data management.

RESULTS:

Thirteen randomized control trials, 6 of which were new ones, were included into this meta-analysis. The overall survival of NSCLC patients in neoadjuvant chemotherapy arm were improved significantly, comparing with those in surgery-alone arm (combined HR = 0.84; 95% confidence interval, 0.77-0.92; p = 0.0001). When only patients with stage III NSCLC were considered, the result was similar (combined HR = 0.84; 95% confidence interval, 0.75-0.95; p = 0.005).

CONCLUSION:

Neoadjuvant chemotherapy, as an addition of surgery, would significantly improve the overall survival of operable NSCLC patients, including patients with stage III NSCLC.
