Combined Active Bone Marrow-Sparing Radiotherapy and Prophylactic PEG-rhG-CSF to Reduce Severe Neutropenia During Platinum-Doublet Concurrent Chemoradiotherapy for Locally Advanced Cervical Cancer: A Phase II Trial

Background

Platinum-doublet concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC) is frequently complicated by severe neutropenia. This Phase II trial investigated whether combining active bone marrow-sparing (ABMS) radiotherapy with prophylactic pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) could reduce the incidence of grade ≥ 3 neutropenia below a prespecified historical benchmark of 30%.
