PKMYT1 can effectively diagnose ccRCC. ROC curves reveal that PKMYT1 expression can differentiate adjacent normal tissues from (A) ccRCC and ccRCC at (B) TNM I stage, (C) TNM II stage, (D) TNM III stage, (E) TNM IV stage, (F) histological stage 1, (G) histological stage 2, (H) histological stage 3, and (I) histological stage 4. ccRCC – clear cell renal cell carcinoma; ROC: receiver operating characteristic; TNM – tumor, node, metastasis.
