Temporal and therapeutic confounders in predicting efficacy of immunotherapy rechallenge via baseline intratumoral tertiary lymphoid structures
Year: 2026
Type: editorial
Abstract: This correspondence discusses the recent multicenter study by Tang et al (2026) regarding the predictive value of baseline mature intratumoral tertiary lymphoid structures for immune checkpoint inhibitor rechallenge in non-clear cell renal cell carcinoma. While we commend the authors’ pioneering efforts, we raise critical methodological and biological considerations. First, the concurrent switching of tyrosine kinase inhibitors in nearly half the cohort acts as a major therapeutic confounding variable. Second, the biological plausibility of response conversion under class-refractory immunotherapy warrants cautious evaluation. Third, the extensive evolutionary stress during front-line therapy highlights a severe temporal decoupling between archival baseline tissue banking and post-resistance rechallenge outcomes. Finally, deeper mechanistic validation via spatial omics and comprehensive exhaustion panels is needed to strengthen these translational findings.
