Impact of therapy and disease‐related symptoms on health‐related quality of life in patients with follicular lymphoma: results of the population‐based PHAROS‐registry

Abstract

The increasing number of longer living patients with follicular lymphoma (FL) and serious side effects of treatment urged us to study the health-related quality of life (HRQoL) and persistent (treatment-related) symptoms in unselected patients after different treatment modalities and compare HRQoL of patients with a normative population. The population-based Eindhoven Cancer Registry was used to select patients diagnosed with FL during 2004-2010. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) was completed twice, with a 1-yr interval. This questionnaire was also completed by an age- and sex-matched normative population (N = 580). Detailed data on treatment were extracted from the cancer registry and Population-based HAematological Registry for Observational Studies (PHAROS). Of the 181 patients who were invited, 148 responded (82%, T1). Patients treated with immunochemotherapy reported clinically relevant higher mean fatigue scores than those who underwent radiotherapy (P = 0.02). No differences were observed on the other HRQoL scales between treatment groups. Mean HRQoL scores were worse for FL patients treated with immunochemotherapy compared with a normative population (P < 0.01). A quarter to 50% of patients persistently reported to be slowed down, lethargic, or persistently worried about future health or was limited in social activities. Subsequently, patients reporting these symptoms/worries had a lower global health status/HRQoL. Alertness for persistent symptoms that occur during and after treatment of FL patients is needed and may help to avoid lasting negative influence on their HRQoL.
