HAVCR1 and neoplasm: High membranous kidney injury molecule‐1 (KIM‐1) expression in pathological T1b (pT1b) clear cell renal cell carcinoma (ccRCC) was significantly associated with a higher nuclear grade, tumor necrosis, hot tumor associated immune cell (TAIC) status, and shorter recurrence‐free survival (RFS) and cancer‐specific survival, and was an independent predictor of shorter RFS.
