Importance

Efforts are underway to deintensified treatment protocols for patients with human papillomavirus virus−associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) to achieve similar excellent oncologic outcomes while reducing treatment-related adverse effects. Transoral robotic surgery (TORS) as primary treatment often requires adjuvant therapy due to the high incidence of nodal metastasis. Treatment with neoadjuvant chemotherapy followed by TORS and neck dissection (NECTORS), reserving radiation therapy for salvage, yields excellent oncologic outcomes.

Objective

To assess patient-reported quality of life (QOL) and functional outcomes among patients with HPV-OPSCC who undergo NECTORS.

Design, Settings, and Participants

This was a multicenter prospective cohort study of patients with HPV-OPSCC treated with the NECTORS protocol in 2017 to 2022. Consecutive patients with stage III or IVa HPV-OPSCC treated with NECTORS in 2017 to 2022 who had completed the primary QOL questionnaire at baseline and at least once during the 24-month follow-up period were included. Ninety-four patients were eligible, and 67 were included in the analyses.

Outcome Measures

QOL questionnaires at baseline, and at month 1, 3, 6, 12, 18, and 24 posttreatment. Global score on the 30-item European Organization for Research and Treatment of Cancer Core quality of life questionnaire (EORTC QLQ-C30) was the primary outcome; the head and neck extension module (EORTC QLQ-HN35); the MD Anderson Dysphagia Inventory for dysphagia-related QOL; and the Decision Regret Scale were also used. Paired t tests assessed change between the baseline and 12- or 24-month patient-reported outcomes.

Results

Among the study population of 67 patients (median [range] age, 63 [58-67] years; 54 [80.6%] male) with HPV-OPSCC, the most frequent cancer subsites were palatine tonsil (41 [61%]) and base of tongue (26 [39%]); none required adjuvant RT. Global QOL at 24 months improved compared with baseline (mean difference, 9.49; 95% CI, 2.45 to 16.53). All EORTC QLQ-C30 functional scores returned to baseline or improved within 3 to 6 months posttreatment and remained stable at 24 months. EORTC QLQ-HN35 symptom scale scores improved or were stable at 24 months. The MD Anderson Dysphagia Inventory scores demonstrated no significant difference between baseline and month 12 for global scores (mean difference, 6.15; 95% CI, −4.18 to 16.49) and composite scores (mean difference, 2.73; 95% CI, −1.62 to 7.09). Median (range) score on the Decision Regret Scale was 5 of 100 (0-30), representing mild overall regret.

Conclusion and Relevance

The findings of this multicenter cohort study indicate that use of the NECTORS protocol is associated with excellent QOL outcomes. QOL measures returned to baseline levels or were better than baseline, which represents positive outcomes for patients with HPV-OPSCC who undergo this treatment regimen.
