Treatment modality impact on quality of life for human papillomavirus-associated oropharynx cancer.

Objectives/hypothesis: Compare treatment-related quality of life (QOL) impact for early-stage human papillomavirus-associated oropharynx squamous cell carcinoma (HPV+ OPSCC) patients. Study

Design: Retrospective cohort at a tertiary center.

Methods: Stage I (T0-2/N0-1) HPV+ OPSCC patients (n = 76) with pretreatment Karnofsky scores ≥80 reported QOL after surgery alone (n = 17, 22%), surgery with adjuvant radiation ± chemotherapy (S-a[C]XRT) (n = 23, 30%), or definitive radiation ± chemotherapy (d[C]XRT) (n = 36, 47%) with the University of Washington QOL version 4 (UW-QOL); European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core Module (EORTC QLQ-C30) and Head and Neck Module (EORTC QLQ-HN35); University of Michigan Xerostomia, and Neck Dissection Impairment Index questionnaires (median follow-up = 2.2 years, interquartile range = 1.0-4.2 years). Treatment adverse events and gastrostomy tube rates were assessed.

Results: Over 87% of each treatment group reported good or better overall QOL. Each group had low gastrostomy tube and treatment-specific complication rates. S-a(C)XRT and d(C)XRT patients had similar mean scores with wide ranges for most individual and all composite categories. S-a(C)XRT compared to d(C)XRT patients reported significantly fewer dental problems (EORTC QLQ-C30/HN35 means = 10.1 vs. 34.3, P = .007), worse appearance (UW-QOL means = 72.8 vs. 82.6, P = .02), and worse coughing (EORTC QLQ-C30/HN35 means = 31.9 vs. 15.7, P = .007). Surgery alone compared to d(C)XRT and S-a(C)XRT patients reported significantly better salivary/taste/oral functions and less pain, financial, oral/dental, and sexual problems.

Conclusions: For early-stage HPV+ OPSCC, patients usually achieve acceptable QOL regardless of treatment. S-a(C)XRT and d(C)XRT patients report generally similar QOL including neck/shoulder pain/function, but with a wide range in a limited patient sample. Surgery alone should be considered, when oncologically and functionally safe, given the better associated QOL. Level of evidence: 4 Laryngoscope, 130:E48-E56, 2020.
