With appropriate adjuvant therapy, TORS achieves excellent functional results for patients with oropharyngeal squamous cell carcinoma. Oncologic outcomes are equivalent or superior to results of other surgical and nonsurgical treatments.

PURPOSE The purpose of this study was to determine if dose de-escalation from 60 to 66 Gy to 30 to 36 Gy of adjuvant radiotherapy (RT) for selected patients with human papillomavirus–associated oropharyngeal squamous cell carcinoma could maintain historical rates for disease control while reducing toxicity and preserving swallow function and quality of life (QOL). PATIENTS AND METHODS MC1273 was a single-arm phase II trial testing an aggressive course of RT de-escalation after surgery. Eligibility criteria included patients with p16-positive oropharyngeal squamous cell carcinoma, smoking history of 10 pack-years or less, and negative margins. Cohort A (intermediate risk) received 30 Gy delivered in 1.5-Gy fractions twice per day over 2 weeks along with 15 mg/m2 docetaxel once per week. Cohort B included patients with extranodal extension who received the same treatment plus a simultaneous integrated boost to nodal levels with extranodal extension to 36 Gy in 1.8-Gy fractions twice per day. The primary end point was locoregional tumor control at 2 years. Secondary end points included 2-year progression-free survival, overall survival, toxicity, swallow function, and patient-reported QOL. RESULTS Accrual was from September 2013 to June 2016 (N = 80; cohort A, n = 37; cohort B, n = 43). Median follow-up was 36 months, with a minimum follow-up of 25 months. The 2-year locoregional tumor control rate was 96.2%, with progression-free survival of 91.1% and overall survival of 98.7%. Rates of grade 3 or worse toxicity at pre-RT and 1 and 2 years post-RT were 2.5%, 0%, and 0%. Swallowing function improved slightly between pre-RT and 12 months post-RT, with one patient requiring temporary feeding tube placement. CONCLUSION Aggressive RT de-escalation resulted in locoregional tumor control rates comparable to historical controls, low toxicity, and little decrement in swallowing function or QOL.

The aim of this retrospective study was to describe the oncologic and functional results of treating oropharyngeal squamous cell carcinoma with transoral robotic surgery and neck dissection as monotherapy. A review was performed, including all patients who underwent transoral robotic surgery and neck dissection as the only means of therapy for oropharyngeal carcinoma from March 2007 to July 2009 at a single tertiary care academic medical center. We reviewed all cases with ≥ 24-month follow-up. Functional outcomes included tracheostomy dependence and oral feeding ability. Oncologic outcomes were stratified by human papillomavirus (HPV) status and tobacco use and included local, regional, and distant disease control, as well as disease-specific and recurrence-free survival. Eighteen patients met study criteria. Ten patients (55.6%) were able to eat orally in the immediate postoperative period, and 8 (44.4%) required a temporary nasogastric tube for a mean duration of 13.6 days (range 3 to 24 days) before returning to an oral diet. No patient required placement of a gastrostomy tube, and all patients are tracheostomy-tube–free. Among the HPV-positive nonsmokers (12/18, 66.7%), Kaplan-Meier estimated 3-year local, regional, and distant control rates were 90.9%, 100%, and 100%, respectively. Kaplan-Meier estimated disease-specific survival and recurrence-free survival were 100% and 90.9%, respectively. No complications occurred.

Objectives Determine the effect of endoscopic skull base surgery (ESBS) on long‐term olfactory outcomes after surgery. Methods An English‐language search was conducted using the Cochrane, MEDLINE, Scopus, and Embase databases from January 2000 to October 2017 for adult patients undergoing ESBS with subjective and objective olfaction outcomes. Two authors independently examined articles to identify those meeting inclusion criteria. Studies examining objective olfactory outcomes after ESBS were included in the meta‐analysis. A random‐effects meta‐analysis of patients undergoing sellar and parasellar ESBS was conducted to compare preoperative and postoperative olfactory outcomes using the University of Pennsylvania Smell Identification Test (UPSIT) and Cross‐Cultural Smell Identification Test (CCSIT). Results Among 339 eligible articles, 29 articles met inclusion criteria. Twenty‐five of these focused on sellar and parasellar tumors. Individual articles not meeting criteria for meta‐analysis were qualitatively reported. Meta‐analysis showed there was no difference in preoperative and postoperative olfactory function after sellar and parasellar ESBS based on the UPSIT (five studies, mean difference [MD] = −1.03; 95% CI: −3.98, 1.93; P = .50) and the CCIST (three studies, MD = −0.77; 95% CI: −3.03, 1.49; P = .50). A pooled overall meta‐analysis revealed similar results (eight studies, effect size = −0.30; 95% CI: −0.79, 0.18; P = .22). However, heterogeneity for all meta‐analyses was high (I2 > 95%, P < .01), suggesting significant variation in the included studies. Conclusions Based on published objective olfaction outcomes after sellar and parasellar ESBS, there was no significant difference between preoperative and postoperative olfaction. Further prospective studies using validated objective measures of olfaction are required to improve our understanding on this subject. Level of Evidence 2a Laryngoscope, 129:1998–2007, 2019

Objectives/Hypothesis Sinonasal mucosal melanoma (SNMM) is a rare malignant neoplasm. No study to date has analyzed the impact that nodal metastases and distant metastases at diagnosis have on overall survival (OS) and disease‐specific survival (DSS). Study Design Retrospective database review. Methods The Surveillance, Epidemiology, and End Results database was queried for cases of SNMM. Descriptive statistics were used analyze patient demographic and clinicopathologic variables. The Kaplan‐Meier model was used to analyze survival, and the Cox proportional hazards model was used for multivariate analysis. Results Three hundred twenty‐eight cases of SNMM were identified. The most frequent sinonasal anatomic location was the nasal cavity in 279 (73.0%) patients, followed by the maxillary sinus in 60 (15.7%) patients. Regional nodal metastases at diagnosis occurred in 33 (8.6%) patients, whereas distant metastases at diagnosis occurred in 41 (10.7%) patients. Five‐year OS was 22.7%, and 5‐year DSS was 26.8%. The presence of positive nodes at diagnosis (OS P < .0001, DSS P < .0001), distant metastases at diagnosis (OS P = .0442, DSS P = .0442), primary tumor site (OS P < .0001, DSS P < .0001), and increasing age (OS P = .0012, DSS P = .0016) were found to be significant as negative predictors of OS and DSS. Conclusions SNMM is a rare pathologic entity with a poor prognosis. The presence of nodal and distant metastases at diagnosis are negative prognostic factors in OS and DSS. These factors can be used in the development of new models of risk stratification and to inform treatment strategies and surveillance patterns. Level of Evidence NA Laryngoscope, 130:622–627, 2020
