Longitudinal Differences By Treatment Arm in Health-Related Quality of Life Among High Risk Pediatric Hodgkin's Lymphoma Patients Treated on the Children's Oncology Group Ahod 1331 Study
Notice bibliographique
Résumé
Introduction: Brentuximab vendotin (BV) with AVE-PC demonstrated superior efficacy to ABVE-PC for pediatric patients with high-risk HL in the AHOD 1331 trial. However, there are no data regarding the impact on health-related quality of life (HRQoL) with the addition of BV into the treatment of pediatric HL. Methods: Eligibility for AHOD 1331 (NCT 02166463) included previously untreated HL with high risk disease, defined as stage IIB +bulk, IIIB, IVA, or IVB classic HL. Participants were randomized to either BV-AVE-PC (“BV” arm) or ABVE-PC (standard arm). Among the first 309 participants enrolled in a prespecified longitudinal patient-reported outcomes sub study, 280 were age 11+ years and eligible to self-report HRQoL using the seven-item Child Health Ratings Inventories (CHRIs)-Global scale. HRQoL was assessed prior to treatment (T1), at cycle 2 (T2), at cycle 5 (T3), and at the end of treatment (T4). A clinically meaningful increase in HRQoL was considered a change of 7 points in the CHRIs-Global score (CHRIs), translating to a 1/3 standard deviation. Multivariable linear regression estimated the association between demographic/clinical variables and HRQoL at T1. Linear mixed models estimated the change in HRQoL relative to T1 with a time*treatment arm interaction to estimate differences in the change in HRQoL across treatment arm. This model was adjusted for age, sex, race/ethnicity, stage, large mediastinal adenopathy (LMA), B-symptoms at diagnosis, and a time-varying covariate for involved site radiation prior to T4. Results: Participant and disease characteristics were balanced by treatment arm; mean age at enrollment was 15.6 years (SD= 1.9), 52% were female, 60.4% had LMA, and 58% were stage IV. 93% of participants completed the CHRIs at T1, 92% at T2, 89% at T3, and 74% at T4. At T1, female sex (mean (SD) 64.1 (20.2) vs 71.3 (23.3) p=0.004) and fever (60.8 (23.0) vs. 71.9 (20.4) p=0.024) were associated with worse HRQoL. At each time point after pre-treatment (T1), HRQoL was higher, on average, in the BV arm compared to the standard arm (Figure 1). By T2, participants in the BV arm experienced a statistically and clinically significant increase in HRQoL compared to pre-treatment (T1) (Table 1; β=7.3 95%CI 3.2, 11.4; p≤0.001), which was greater than the change experienced in the standard arm (difference in change β=5.1 95%CI -0.2, 10.3; p=0.057). At T3 and T4 the BV arm continued to experience statistically significant improvements in HRQoL relative to T1 (T3 β=5.3 95%CI 0.8, 9.9; p=0.022; T4 β=14.6 95%CI 10.3, 18.9; p≤0.001). The standard arm did not experience a statistically or clinically significant increase in HRQoL from T1 until T4 (β=9.3 95%CI 4.7, 11.5; p<0.001). Conclusion: Patients with high-risk pediatric HL treated with BV-AVE-PC experienced more rapid and sustained improvement in HRQoL compared to patients treated with ABVE-PC. These data also demonstrate the feasibility and importance of incorporating HRQoL assessments into pediatric clinical trials.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
