Developing a precision approach to anesthetic/analgesic immunomodulation in cancer, exploring biomarkers (TMB, FGA) predictive of immunotherapy response and resistance. Analyzing drug effects on survival and recurrence in lung and colon adenocarcinoma patients, correlating drug target receptor gene expression with TMB, FGA, and immune cell types. Suggesting TMB and FGA as predictive biomarkers for anesthetic/analgesic dose effects on cancer patient survival.
