Analyze overall survival association of gene expression in TCGA cancer patients using cBioPortal data. Performs log-rank test comparing high vs. low gene expression groups (median split). Returns log-rank p-value, median survival times, and event counts. Note: TIMER2.0/3.0 REST API is no longer public; uses cBioPortal TCGA data.
