RecruitingPatient-Reported Outcomes and Quality of Life in Adult and Pediatric Patients With Nodular Lymphocyte-Predominant Hodgkin Lymphoma (NLPHL)There is a pressing need to measure patient-reported symptoms in patients of all ages diagnosed with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). This study aims to measure longitudinal symptom burden and treatment tolerability utilizing validated patient-reported outcomes (PROs) instruments. Primary Objective: * To develop the data collection infrastructure required to prospectively collect longitudinal electronic patient-reported outcomes (PROs) survey instruments in adult and pediatric patients diagnosed with NLPHL. Secondary Objective: * To examine differences in baseline and longitudinal changes in PROs based on disease characteristics, disease status, and treatment strategies among adult and pediatric patients diagnosed with NLPHL.
