Objectives: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is rapidly increasing in the United States. The aim of this study was to characterize the functional status of OPSCC survivors to identify predictors of swallowing dysfunction in this patient population. Methods: OPSCC survivors (n = 81) treated at the Michael E. DeBakey Veterans Affairs Medical Center between 2005 and 2015 with at least 2 years of clinical follow-up were reviewed. Functional status was ascertained using (1) gastrostomy and tracheostomy placement and retention, (2) gastrostomy use at last follow-up, (3) patient-reported diet, and (4) modified barium swallow. Results: Median follow-up duration was 5.6 years; 67% of patients had ≥10-pack-year tobacco exposure; 96% of tumors for which p16 data were available were p16 positive. At last follow-up, 82% of patients reported a regular diet, and only 9 patients required gastrostomy use. Gastrostomy use at last follow-up was higher in patients with T3 and T4 tumors compared with those with T1 and T2 tumors ( P = .01). The relationship between T classification and gastrostomy use persisted even when the analysis was limited to p16+ tumors and p16+ tumors with ≥10-pack-year history of tobacco exposure. Conclusions: Advanced T classification at presentation is a critical predictor of gastrostomy use in long-term OPSCC survivors irrespective of p16 status or tobacco exposure history.

ObjectiveOropharyngeal squamous cell carcinoma (OPSCC) incidence is rapidly increasing, as are survival rates, in large part due to the human papillomavirus (HPV). Treatment intensity, however, has remained unchanged, making treatment‐related toxicity (i.e., dysphagia) a critical problem for an increasing number of patients. The primary objective of this study was to determine whether pretreatment objective swallowing measures can predict percutaneous fluoroscopic guided gastrostomy tube (PFG) utilization during OPSCC treatment.MethodsForty‐one newly diagnosed OPSCC patients treated with radiation underwent evaluation of swallow function with modified barium swallow study (MBSS) prior to and at completion of radiation treatment using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST); a subset of patients were evaluated using the MD Anderson Dysphagia Inventory (MDADI).ResultsPatients were male (100%), primarily Caucasian (85.4%) and p16 positive (85.4%) with mean age of 65.7 years. PFG were placed in 70.7% patients (n = 29) and used by 63.4% (n = 26). Pre‐ and post‐treatment DIGEST scores were associated with T‐classification (t = −2.9, p = .001, t = −2.7, p = .01) and indicated deteriorating swallow function during treatment (mean change = 0.46 [t = −2.7, p = .01]). DIGEST and MDADI scores were generally not associated with patient PFG utilization. DIGEST and MDADI scores were significantly correlated prior to, but not following completion of treatment.ConclusionPre‐treatment DIGEST and patient reported swallowing outcomes (MDADI) can be useful in identifying patients with unsafe and/or grossly inefficient swallowing function. However, objectively measured swallow function was not associated with PFG utilization. Development of PFG placement algorithms (reactive vs. prophylactic) therefore require additional inputs/metrics.Level of Evidence4 Laryngoscope, 130:2153–2159, 2020
