CXCL13 and nonpapillary renal cell carcinoma: To further portray intratumoral immunophenotypes according to genomic alterations of MTAP and CDKN2A, we evaluated the expression levels of the immune checkpoint molecule, PD-L1, and the key lymphokine that recruits tertiary lymphoid structures, CXCL13, in ccRCC samples with available genomic data from the discovery set of the FUSCC cohort.
