摘要
Panel-based comprehensive genomic profiling is used in clinical practice worldwide; however, large real-world datasets of patients with advanced gastric cancer are not well known. We investigated what differences exist in clinically relevant alterations for molecularly defined or age-stratified subgroups. This was a collaborative biomarker study of a real-world dataset from comprehensive genomic profiling testing (Foundation Medicine, Inc.). Hybrid capture was carried out on at least 324 cancer-related genes and select introns from 31 genes frequently rearranged in cancer. Overall, 4634 patients were available for analyses and were stratified by age (≥ 40/< 40 years), microsatellite instability status, tumor mutational burden status (high 10 ≥ /low < 10 Muts/Mb), Epstein–Barr virus status, and select gene alterations. We analyzed the frequency of alterations with a chi-square test with Yate’s correction. Genes with frequent alterations included TP53 (60.1
