TP53 mutation predict poor prognosis in diffuse large B-cell lymphoma: a single-center study.

ABSTRACT: Whether TP53 mutation can serve as a simplified prognostic surrogate for complex genomic classifiers in diffuse large B-cell lymphoma (DLBCL) remains unclear. we comprehensively analyzed a retrospective cohort of 444 newly diagnosed DLBCL patients. TP53 mutation was an independent prognostic factor for inferior overall survival (OS) and progression-free survival (PFS) (both P < 0.001), correlating with inferior response to R-CHOP and enrichment in refractory/relapsed disease. Furthermore, multivariate analysis revealed that the adverse prognostic effect of TP53 mutation was predominantly driven by its impact within the germinal center B-cell-like (GCB) subtype, as evidenced by a significant statistical interaction. Notably, the combination of TP53 mutation and double-expression lymphoma (D
