Abstract
Indolent B-cell non-Hodgkin lymphomas(B-NHL) encompass a heterogeneous category of lymphomas characterized by a wide range of pathological subtypes. With the application of chemoimmunotherapy with rituximab (R-chemo), the prognosis of patients has improved considerably, with a 10-year survival rate of 60-80%. Despite these advancements, a significant number of patients still experience disease progression during or shortly after initial treatment. Those who progress within the first 24 months (POD24) continue to face a notably worse prognosis. This study aims to explore the significance of POD24 in predicting the prognosis of different subtypes of indolent B-cell NHL through a comprehensive literature review. The investigation extends to examining the existing prognostic assessment tools and evaluating the interrelationship between POD24 and these tools. By synthesizing relevant research findings, this study seeks to contribute to the current understanding of the role POD24 plays in prognostic evaluation and its potential implications in guiding clinical decision-making for patients with indolent B-cell NHL.
