Isolated HLA‑DQB1 Mismatch and Donor Age Do Not Worsen Survival After Unrelated Donor HCT with Post‑Transplant Cyclophosphamide: A Single‑Center Analysis

A single‑center retrospective study of 988 unrelated donor HCTs with PTCy found no significant differences in survival or relapse for isolated HLA‑DQB1 mismatch, 7/8 mismatches, or older donor age; 7/8 mismatch increased severe acute GVHD and donor age modestly raised risk of grade II–IV aGVHD.
