Figure 4. AK7 can be used as a prognostic indicator and a predictor of immunotherapy effect in ccRCC patients. (A) In pancarcinoma, patients with high expression of AK7 have a better prognosis than those with low expression. (B) In ccRCC, patients with high expression of AK7 had longer OS than those with low expression. (C) In ccRCC at stage 4, patients with high expression of AK7 had longer OS than those with low expression. (D–F) In patients treated with anti-PD1 (D), anti-PD-L1 (E), and anti-CTLA-4 (F), high expression of AK7 has a better prognosis. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
