Results of a longitudinal survey on quality of life (QoL) in 935 patients with supradiaphragmatic early stage Hodgkin lymphoma (HL) enrolled in the EORTC-GELA H8 trial (# 20931)

Abstract

8582 Background: To study the change in posttreatment QoL and fatigue in patients with supradiaphragmatic early stage HL. Methods: QoL assessment was made using the EORTC QLQ-C30 core questionnaire and fatigue was assessed using the MFI-20 questionnaire. Questionnaires were given immediately after treatment completion and every 6 months thereafter for at least a period of 5 years. Mixed models (Med Decis Making 2003;3:54–66) were used to assess statistically reliable changes of the variables tested with time because they allow unequal number of assessments per patients. Variables tested were the 7 functioning scales and the fatigue scale of the QLQ-C30 questionnaire, the 5 MFI-20 fatigue scales, and time using 6 time periods: 0–6, 7–14, 15–21, 22–32, 33–47, ≥48 months following the end of treatment. The impact of gender, age (<30, 30–49, ≥50 years), treatment (mantle-field irradiation, subtotal nodal irradiation (STNI), 3, 4 or 6 MOPP-ABV and involved-field irradiation or 4 MOPP-ABV and STNI) and treatment-related acute grade 3–4 toxicity was also tested. Patients were censored at relapse when occurred. Results: Of the 1577 patients enrolled in the trial (1993–1998), 935 (59%, median follow-up 7 years) participated for a total of 3,227 assessments. Main clinical characteristics did not differ between patients with missing QoL forms and those with complete data. There were no significant differences in disease-free survival between treatment arms. Significant (P<0.001) improvement with time was observed for all QoL and fatigue variables tested. Overall, young age and male sex significantly (P<0.01) correlated with improvement in all QLQ-C30 dimensions except cognitive functioning. Treatment duration ≥6 months had a significant (P<0.005) negative impact on global QoL. Age≥30 years and treatment duration ≥2 months negatively (P<0.05) influenced MFI-20 variable changes. Previous toxicity and age ≥30 years altered mental fatigue and motivation. Conclusions: QoL data from the reintegration process of patients into normal life during the first follow-up years show substantial limitations. The impact of treatment is limited. Fatigue remains of great concern in these patients. No significant financial relationships to disclose.
