Symptom burden, quality of life, functioning and emotional distress in survivors of human papillomavirus associated oropharyngeal cancer: An Australian cohort

Abstract

Background: This cross-sectional study examines patient-reported outcomes and functioning-based subgroups in human papillomavirus-associated oropharyngeal cancer survivors treated with chemoradiotherapy ≥12 months prior.

Method: Survivors completed EORTC QLQ-C30, MDASI-HN and PROMIS-Emotional distress questionnaires. Subgroups were identified via two-step clustering of QLQ-C30 functioning scales.

Results: 136 patients were enrolled. Clinicians' graded 19/136 (14%) patients as having at least one severe (Grade 3 CTCAE) toxicity, whereas 68/136 (50%) patients self-reported at least one toxicity in the severe range (MDASI-HN ≥ 7). QLQ-C30 Global health status score (mean 76, SD = 20) was comparable to population norms. Rates of moderate/severe anxiety (10%/1%) and depression (4%/1%) were low. Two functioning-based subgroups were formed based on auto-clustering statistics: high- (n = 93) and low-functioning (n = 41). Differences on all functioning scales were large (d: 1.57-2.29), as were differences on the remaining QLQ-C30 scales/items, most MDASI-HN symptom severity/interference scales, and PROMIS scales (d: 0.80-2.03). Differences and associations with patient/clinical characteristics were not significant.

Conclusion: In this Australian cohort of HPV-OPC survivors there was significant discordance between clinician- and patient-reported toxicity. We observed population comparable global quality of life and low rates of emotional distress. However, we identified a low-functioning subgroup reporting significantly worse outcomes on a range of patient-reported measures who may benefit from targeted support.
