Early histological transformation of follicular lymphoma to diffuse large B‐cell lymphoma indicating adverse survival: A population‐based analysis and validation

The histological transformation (HT) of follicular lymphoma (FL) is a crucial biological event. The study aimed to evaluate the incidence, clinicial characteristics, prognosis and impact of HT time on survival of FL transforming to diffuse large B-cell lymphoma in population-based large-scale cohorts.
