Background The COVID-19 pandemic has required triage and delays in surgical care throughout the world. The impact of these surgical delays on survival for patients with head and neck squamous cell carcinoma (HNSCC) remains unknown. Methods A retrospective cohort study of 37 730 patients in the National Cancer Database with HNSCC who underwent primary surgical management from 2004 to 2016 was performed. Uni- and multivariate analyses were used to identify predictors of overall survival. Bootstrapping methods were used to identify optimal time-to-surgery (TTS) thresholds at which overall survival differences were greatest. Cox proportional hazard models with or without restricted cubic splines were used to determine the association between TTS and survival. Results The study identified TTS as an independent predictor of overall survival (OS). Bootstrapping the data to dichotomize the cohort identified the largest rise in hazard ratio (HR) at day 67, which was used as the optimal TTS cut-point in survival analysis. The patients who underwent surgical treatment longer than 67 days after diagnosis had a significantly increased risk of death (HR, 1.189; 95% confidence interval [CI], 1.122–1.261; P < 0.0001). For every 30-day delay in TTS, the hazard of death increased by 4.6%. Subsite analysis showed that the oropharynx subsite was most affected by surgical delays, followed by the oral cavity. Conclusions Increasing TTS is an independent predictor of survival for patients with HNSCC and should be performed within 67 days after diagnosis to achieve optimal survival outcomes.

Objectives/Hypothesis We investigate the clinicopathologic and treatment factors associated with the use of postoperative radiation therapy (PORT) and its effect on overall survival (OS) for patients with oral cavity verrucous carcinoma (VC). Study Design Retrospective cohort study. Methods A retrospective cohort study of the National Cancer Database (NCDB) from 2006 to 2015 was performed. Multivariable logistic regression was used to identify independent predictive factors associated with the use of PORT. Cox Regression survival and propensity score analyses were used to evaluate the effect of PORT on mortality. Results A total of 356 adult patients with primary oral cavity VC who underwent definitive surgical resection were identified. A total of 10.7% of patients underwent definitive surgical resection followed by PORT. Variables associated with PORT included distance to the hospital per 10 miles (adjusted odds ratio [aOR], 0.81 [95% confidence interval (CI), 0.70–0.95]) and stage III–IV disease (aOR, 12.13 and 23.92, respectively). Multivariable Cox regression survival analysis indicated no evidence of survival benefit in patients undergoing PORT compared to surgery alone (adjusted hazard ratio 1.50 [0.74–3.05], P = .23). Propensity score analysis also showed no OS benefit with the use of PORT (P = .41). Conclusions Variables associated with the use of PORT on multivariable analysis included closer distance to hospital and stage III–IV disease. No clear survival benefit with PORT was identified on either multivariable survival analysis or propensity score analysis. These results suggest that surgery alone with negative margins may be the optimal treatment for patients with oral cavity VC. Level of Evidence 4 Laryngoscope, 132:1953–1961, 2022
