Progression-free survival at 24 months as a predictor of survival outcomes after CHOP treatment in patients with peripheral T-cell lymphoma: a single-center validation study in a Japanese population

Peripheral T-cell lymphoma (PTCL) is a group of aggressive lymphomas commonly treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). Progression-free survival at 24 months (PFS24) constitutes a survival predictor for some lymphomas but has not been examined in Asian populations. We retrospectively investigated whether PFS24 was predictive of survival outcomes after CHOP treatment in 73 Japanese patients with PTCL. Patients without PFS24 had shorter median subsequent overall survival (OS) (20.2 vs. 121.0 months
