Abstract
There is still limited comprehensive genotyping data about young patients with lung adenocarcinoma. Herein, next generation sequencing (NGS) data of lung adenocarcinoma patients was retrospectively analyzed to evaluate the relationship between young age at diagnosis and the comprehensive molecular characteristics. The cBioPortal for Cancer Genomics database was queried for cancer genomic studies of lung adenocarcinoma and a cohort of 773 patients with complete cancer genomics data was selected from 2 of 11 studies. The relationship between age at diagnosis and frequency of targetable genotypes was analyzed and verified in another cohort composed of 177 Chinese lung adenocarcinoma patients undergoing NGS assay. Of the 773 eligible lung adenocarcinoma patients, younger age was associated with an increased likelihood of a targetable genotype (P < .001). Specifically, a higher prevalence of EGFR mutations (P = .005), ALK arrangements, ROS1 arrangements (P = .035) and RET arrangements (P < .001) were identified in younger patients. The frequency of KRAS mutations (P < .001) was significantly associated with older age at diagnosis and a similar trend existed for METÂ...
