We leveraged the Phase III Fondazione Italiana Linfomi FOLL12 trial, which treated patients with advanced-stage FL with R-CHOP or R-Bendamustine, to evaluate the role of myeloid CH at baseline and after chemoimmunotherapy (CIT). Patients acquiring fit DDR clones (N = 37) had inferior long-term outcomes, including independent increased risk of second malignancies (hazard ratio [HR] 2.63, P = 0.035) that developed in 28 patients, and shorter OS (HR 3.28, P = 0.008). CH emerges as a novel and potentially valuable biomarker in FL, capable of predicting long-term toxicities that are key endpoints in indolent lymphoid malignancies characterized by long-lasting survival.
This analysis supports a model of PCFCL oncogenesis driven by circulating progenitors following complex evolutionary patterns, including convergent evolution and greater clonal diversity at relapse. Overall, our study refines the mechanisms driving PCFCL pathogenesis, while providing a framework for PCFCL differential diagnosis and clinical management.

In this contemporary POL series, clinicopathologic heterogeneity was prominent, and laboratory profiles frequently overlapped with ovarian malignancy work-up. Outcomes may be favorable among patients receiving timely, subtype-appropriate systemic treatment.
