Factors affecting the efficacy and safety of docetaxel combined with platinum in the treatment of advanced non-small cell lung cancer

This study aimed to quantitatively evaluate factors influencing the efficacy and safety of the docetaxel-platinum regimen to provide reliable information for optimizing chemotherapy regimens.A parametric survival function model was used to describe the time course of overall survival (OS) of patients with advanced non-small cell lung cancer (NSCLC) receiving a docetaxel-platinum regimen. A random-effects model in a single-arm meta-analysis was used to analyze the objective response rate and grade 3-4 adverse event rates based on various docetaxel-platinum regimens.The model revealed that the risk of death in East Asians was approximately 1.5-fold higher than that in non-East Asians, with a median OS of 13.7 (95% confidence interval [CI]: 12.8-14.7) months and 9.3 (95% CI: 7.7-11.1) months, respectively. No significant impact of different administration regimens on OS was found. However, when drug exposure increased, the incidence of grade 3-4 anemia or neutropenia significantly increased.The docetaxel-platinum regimen has different efficacies in the treatment of advanced NSCLC between East Asian and non-East Asian populations. A better benefit-risk ratio can be obtained with a lower exposure regimen of docetaxel combined with platinum.
