Systemic Mastocytosis in 910 Patients: Prognostic Contribution of the International Consensus Classification in the Context of the Mayo Alliance Prognostic System.

ABSTRACT: The current study includes 910 patients with systemic mastocytosis (SM) seen at the Mayo Clinic from 1968 to 2024. The primary objective was to examine the prognostic contribution of the International Consensus Classification (ICC), in the context of the Mayo Alliance Prognostic System (MAPS) for SM. World Health Organization classification (WHO-HAEM5) subcategories included (i) indolent/smoldering SM (ISM/SSM; N = 518), (ii) SM associated with another hematological neoplasm (SM-AHN; N = 273), with the latter including both myeloid and lymphoid neoplasms, (iii) aggressive SM (ASM; N = 106), and (iv) WHO-defined mast cell leukemia (MCL; N = 13), which included mast cells with both "mature" and "immature" morphology.
