Gastrostomy tube dependence and patient-reported quality of life outcomes based on type of treatment for human papillomavirus-associated oropharyngeal cancer: Systematic review and meta-analysis.

Abstract

We examined the impact of treatment modality on gastrostomy tube dependence and patient-reported outcomes in human papillomavirus-associated oropharyngeal cancer (HPV-OPSCC). We performed systematic review and meta-analysis of functional outcomes 1-3 years after treatment. Twenty-three studies were included, reporting on 3127 patients treated for HPV-OPSCC. Gastrostomy tube dependence failed to show statistically significant difference between surgery with adjuvant therapy and chemoradiotherapy with cisplatin at 12 months (8.3% [95% CI: 3.1-15.9] vs. 4.2% [1.1-9.2], p=0.37) and 24-36 months (10.5% [95% CI: 3.2-21.5] vs. 3.3% [2.0-4.9], p=0.06). Surgery with adjuvant therapy was associated with worse University of Washington Quality of Life (UW-QOL) Swallowing (84 [95% CI: 80-88] vs. 89 [87-90], p=0.03) and UW-QOL Overall scores (76 [95% CI: 72-80] vs. 84 [81-86], p=0.001) compared to chemoradiotherapy with cisplatin at 12 months. Surgery with adjuvant therapy was associated with worse performance on certain measures of patient-reported swallow and overall function compared to chemoradiotherapy with cisplatin. Further randomized controlled trials are needed to directly compare functional outcomes after treatment for HPV-OPSCC.
