Genes associated with increased brain metastasis risk in non–small cell lung cancer: Comprehensive genomic profiling of 61 resected brain metastases versus primary non–small cell lung cancer (Guangdong Association Study of Thoracic Oncology 1036)

These findings yield detailed insights into the genomic complexity and heterogeneity of primary NSCLC and matched BMs. This study highlights the significant correlation of PI3K signaling with increased metastatic risk in patients with NSCLC and identifies genomic alterations enriched in NSCLC BMs that could serve as prognostic markers and potential therapeutic targets for treating patients with NSCLC BMs.
