GWAS study of myelosuppression among NSCLC patients receiving platinum-based combination chemotherapy.

ABSTRACT: Platinum-based chemotherapy remains the mainstay for non-small cell lung cancer (NSCLC), but it frequently causes dose-limiting myelosuppression, with significant individual variability in susceptibility. However, the genetic basis of myelosuppression side effects remains elusive, greatly hindering personalized therapeutic approaches. In this study, we perform a comprehensive genome-wide association analysis on 491 NSCLC patients receiving platinum-based chemotherapy, examining 4,690,998 single-nucleotide polymorphisms (SNPs) to identify relevant genetic variants. LDBlockShow, FUMA, and MAGMA are utilized to explore linkage disequilibrium, expression quantitative trait loci (eQTLs), chromatin interaction, and conduct gene-based and gene set-based analysis of candidate SNPs.
