Tertiary lymphoid structures (TLS) are organized aggregates of immune cells that form under pathological conditions. However, the predictive value of TLS in clear cell renal cell carcinoma (ccRCC) for immunotherapies remains unclear. We comprehensively assessed the implications for prognosis and immunological responses of the TLS spatial and maturation heterogeneity in 655 ccRCC patients. A higher proportion of early‐TLS was found in peritumoral TLS, while intratumoral TLS mainly comprised secondary follicle‐like TLS (SFL‐TLS), indicating markedly better survival. Notably, presence of TLS, especially intratumoral TLS and SFL‐TLS, significantly correlated with better survival and objective reflection rate for ccRCC patients receiving anti‐Programmed Cell Death Protein‐1 (PD‐1)/Programmed Cell Death‐Ligand‐1 (PD‐L1) immunotherapies. In peritumoral TLS cluster, primary follicle‐like TLS, the proportion of tumor‐associated macrophages, and Treg infiltration in the peritumoral regions increased prominently, suggesting an immunosuppressive tumor microenvironment. Interestingly, spatial transcriptome annotation and multispectral fluorescence showed that an abundance of mature plasma cells within mature TLS has the capacity to produce IgA and IgG, which demonstrate significantly higher objective response rates and a superior prognosis for ccRCC patients subjected to immunotherapy. In conclusion, this study revealed the implications of TLS spatial and maturation heterogeneity on the immunological status and clinical responses, allowing the improvement of precise immunotherapies of ccRCC.
