Clinicogenetic Risk Models In Patients Randomized To Receive Consolidative Autologous Stem-Cell Transplantation After Frontline R-Chop For Advanced Follicular Lymphoma: An Analysis From The Glsg2000 Trial

Introduction: Advanced follicular lymphoma (FL) is a clinically and molecularly heterogeneous disease. About 20% of patients have early progression of disease (POD) and short overall survival (OS). We have previously shown that integration of lymphoma-specific gene mutations and clinical factors improves pretreatment risk stratification (Pastore, 2015) and prediction of early POD (i.e., within 24 months, POD24; Jurinovic, 2016). Recently, we have shown that high-dose therapy (HDT) followed by autologous stem-cell transplantation (ASCT) is an effective treatment option for eligible patients with high-risk disease as defined by POD24 (Jurinovic, 2018). Here, we aimed to explore whether HDT/ASCT is an effective frontline therapy for patients identified to be high-risk by clinical (i.e., FLIPI) or clinicogenetic risk models (i.e., m7-FLIPI, POD24-PI).
