Functional Impact of Transoral Surgery and Risk-Based Adjuvant Therapy in Human Papillomavirus–Associated Oropharyngeal Cancer: Swallowing Outcomes From ECOG-ACRIN E3311
PURPOSE The ECOG-ACRIN E3311 phase II trial demonstrated outstanding disease control (90.6% 54-month progression-free survival) after transoral surgery (TOS) with de-escalated, risk-based postoperative management in resectable human papillomavirus–associated oropharyngeal cancer. The goal of de-escalation was functional preservation. The objective of this work was to evaluate clinician-graded modified barium swallow (MBS) studies from E3311 over time and across arms for (1) aspiration and high-grade pharyngeal residue rates, (2) differences in swallow safety and efficiency, and (3) accuracy of site clinicians reporting against central MBS review. METHODS Eight hundred eighty-five MBS studies were performed on 314 patients from 50 of 59 sites at baseline, post-TOS, and 6 and 24 months postradiotherapy (RT). Swallow outcomes (aspiration, high-grade residue) were recorded by site clinicians. A subset of 414 MBS studies was centrally graded using penetration-aspiration scale scores and the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale. RESULTS Aspiration, residue, and dysphagia rates significantly increased from baseline to post-TOS ( P < .01) and then decreased modestly at 6 and 24 months. At 6 months, swallow outcomes favored the 50- versus 60-Gy arm, with significantly lower aspiration and high-grade dysphagia rates, but this difference was not maintained at 24 months. MBS results reported by site clinicians demonstrated substantial agreement with those assessed by the central laboratory (PABAK, 0.75-0.84; P < .01). CONCLUSION Swallowing worsened after TOS but improved by 6 and 24 months despite adjuvant therapy. De-escalated adjuvant RT at 50 Gy reduced acute aspiration. Site-reported MBS metrics strongly aligned with DIGEST, showing potential as an accessible metric in cooperative group settings.
