Here, we analysed EHR records from a large cohort of 3285 lung, renal, melanoma and other cancer patients who received ICI therapy to determine how frequently the Fearon consensus criteria, WLGS, NLR, albumin, PNI, CRP and mGPS were collected in routine clinical practice and evaluate their prognostic ability at the time of ICI initiation. The gene discussed is ALB; the disease is cancer.
