Novel roles of SETD2 in tumor metabolism and immunotherapy: a systematic review and meta-analysis

This meta-analysis identifies SETD2 as an epigenetic regulator linking tumor metabolic reprogramming to antitumor immunity. SETD2 loss was associated with altered metabolic states and reduced clinical benefit from immune checkpoint inhibitors, with the strongest translational relevance observed in ccRCC and substantial evidence in NSCLC and CRC. These findings support further prospective validation and standardized assessment of SETD2, as well as exploration of rational metabolic-immunotherapy combination strategies in SETD2-deficient tumors.
