Objectives To update the Massachusetts General Hospital (MGH) and Massachusetts Eye and Ear Infirmary (MEEI) experience in the management of esthesioneuroblastoma (ENB) with multimodality therapy and to reassess treatment outcomes and complications in a larger cohort with longer follow-up times. Design A retrospective chart review. Setting A tertiary referral center. Participants All patients presenting with ENB and managed at the MGH and MEEI from 1997 to 2013. Main Outcome Measures Disease-free and overall survival. Results Twenty-two patients were identified with an average follow-up of 73 months. Ten patients presented with Kadish stage B disease and 12 with stage C disease. A total of six patients (27%) developed regional metastases. Treatment for all patients included craniofacial resection (CFR) followed by proton beam irradiation with or without chemotherapy. The 5-year disease-free and overall survival rates were 86.4% and 95.2%, respectively, by Kaplan-Meier analysis. Negative margins were a significant factor in disease-free survival. One patient experienced severe late-radiation toxicity. Conclusions ENB is safely and effectively treated with CFR followed by proton beam irradiation. The high incidence of regional metastases warrants strong consideration for elective neck irradiation. Proton beam radiation is associated with lower rates of severe late-radiation toxicity than conventional radiotherapy. [ABSTRACT FROM AUTHOR]

Purpose: Surgery often represents the best chance for disease control in locoregionally recurrent squamous cell carcinoma of the head and neck (SCCHN). We investigated dual immune-checkpoint inhibition [anti-PD-1, nivolumab (N), and anti-KIR, lirilumab (L)] before and after salvage surgery to improve disease-free survival (DFS)., Patients and Methods: In this phase II study, patients received N (240 mg) + L (240 mg) 7 to 21 days before surgery, followed by six cycles of adjuvant N + L. Primary endpoint was 1-year DFS; secondary endpoints were safety, pre-op radiologic response, and overall survival (OS). Correlatives included tumor sequencing, PD-L1 scoring, and immunoprofiling., Results: Among 28 patients, the median age was 66, 86% were smokers; primary site: 9 oral cavity, 9 oropharynx, and 10 larynx/hypopharynx; 96% had prior radiation. There were no delays to surgery. Grade 3+ adverse events: 11%. At the time of surgery, 96% had stable disease radiologically, one had progression. Pathologic response to N + L was observed in 43% (12/28): 4/28 (14%) major (tumor viability, TV ≤ 10%) and 8/28 (29%) partial (TV ≤ 50%). PD-L1 combined positive score (CPS) at surgery was similar regardless of pathologic response ( P = 0.71). Thirteen (46%) recurred (loco-regional = 10, distant = 3). Five of 28 (18%) had positive margins, 4 later recurred. At median follow-up of 22.8 months, 1-year DFS was 55.2% (95% CI, 34.8-71.7) and 1-year OS was 85.7% (95% CI, 66.3-94.4). Two-year DFS and OS were 64% and 80% among pathologic responders., Conclusions: (Neo)adjuvant N + L was well tolerated, with a 43% pathologic response rate. We observed favorable DFS and excellent 2-year OS among high-risk, previously treated patients exhibiting a pathologic response. Further evaluation of this strategy is warranted.

Objective: As large single-surgeon series in the literature are lacking, we sought to review a single-surgeon's experience with parotidectomy in an academic center, with a focused analysis of pathology, technique, and facial nerve (FN) weakness. Benchmark values for complications and operative times with routine trainee involvement and without continuous FN monitoring are offered., Materials and Methods: All patients who underwent parotidectomy, performed by D. G. D., for benign and malignant disease between January 2004 and December 2018 at an academic center were reviewed., Results: A total of 924 parotidectomies, with adequate evaluatable data were identified. The majority of patients had benign tumors (70.9%). Partial/superficial parotidectomy was the most common approach (65.7%). Selective FN branch sacrifice was rare (12.3%), but significantly more common among patients with malignant pathology (33.8% vs 3.5% for benign, P  < .0001). Among patients with intact FN, post-operative short- and long-term FN weaknesses were rare (6.5% and 1.7%, respectively). These rates were lower among patients with benign tumors (5.4% and 1.3%). Partial/superficial parotidectomy for benign tumors was associated with a low rate of short- and long-term FN weaknesses (2.7% and 0.9%). Mean OR time was 185 minutes., Conclusion: This is the largest single-surgeon series on parotidectomy, spanning 15 years. We demonstrate excellent long- and short-term FN paresis rates with acceptable operative times without regular use of continuous FN monitoring and with routine trainee involvement. These findings may provide valuable insight into parotid tumor pathology, FN outcomes, and feasibility and expectations of performing parotidectomy in an academic setting., Level of Evidence: 4., Competing Interests: The authors declare no conflicts of interest., (© 2020 The Authors.

Objective: The need for intensive care unit (ICU) admission and mechanical ventilation after head and neck microvascular free flap reconstructive surgery remains controversial. Our institution has maintained a longstanding practice of immediately taking patients off mechanical ventilation with subsequent transfer to intermediate, non-ICU level of care with specialized otolaryngologic nursing. Our objective was to describe postoperative outcomes for a large cohort of patients undergoing this protocol and to examine the need for routine ICU transfer., Materials and Methods: We performed a retrospective review of 512 consecutive free flaps treated with a standard protocol of immediate postoperative transfer to an intermediate-level care unit with specialized otolaryngology nursing. Outcome measures included ICU transfer, ventilator requirement, flap failure, postoperative complications, and length of stay. Predictors of ICU transfer were identified by multivariable logistic regression., Results: The vast majority of patients did not require intensive care. Only a small fraction (n = 18 patients, 3.5%) subsequently transferred to the ICU, most commonly for respiratory distress, cardiac events, and infection. The most common complications were delirium/agitation (n = 55; 10.7%) and pneumonia (n = 51; 10.0%). Sixty-five cases (12.7%) returned to the OR, most commonly for hematoma/bleeding (n = 41; 8.0%) and anastomosis revision (n = 20; 3.9%). Heavy alcohol consumption and greater number of medical comorbidities were significant predictors of subsequent ICU transfer., Conclusions: Among head and neck free flap patients, routine cessation of mechanical ventilation and transfer to intermediate-level care with specialized ENT nursing was found to be safe with infrequent subsequent ICU transfer and low complication rates. Routine transfer to intermediate-level care in this population may prevent unnecessary ICU utilization and facilitate the delivery of high-value, disease-centered care., Level of Evidence: 3b.

Objective: The share of total abdominal aortic aneurysm (AAA) repairs performed by endovascular aneurysm repair (EVAR) increased rapidly from 32% in 2001 to 65% in 2006 with considerable variation between states. We hypothesized that hospitals in competitive markets were early EVAR adopters and had improved AAA repair outcomes., Methods: Nationwide Inpatient Sample and linked Hospital Market Structure (HMS) data was queried for patients who underwent repair for nonruptured AAA in 2003. In HMS, the Herfindahl Hirschman Index (HHI, range 0-1) is a validated and widely accepted economic measure of competition. Hospital markets were defined using a variable geographic radius that encompassed 90% of discharged patients. We conducted bivariate and multivariable linear and logistic regression analyses for the dependent variable of EVAR use. A propensity score-adjusted multivariable logistic regression model was used to control for treatment bias in the assessment of competition on AAA repair outcomes., Results: A weighted total of 21,600 patients was included in our analyses. Patients at more competitive hospitals (lower HHI) were at increased odds of undergoing EVAR vs open repair (odds ratio, 1.127 per 0.1 decrease in HHI; P < .0127) after adjusting for patient demographics, comorbidities, and hospital level factors (bed size, teaching status, AAA repair volume, and ownership). Competition was not associated with differences in in-hospital mortality or vascular, neurologic, or other minor postoperative complications., Conclusions: Greater hospital competition is significantly associated with increased EVAR adoption at a time when diffusion of this technology passed its tipping point. Hospital competition does not influence post-AAA repair outcomes. These results suggest that adoption of novel vascular technology is not solely driven by clinical indications but may also be influenced by market forces., (Copyright © 2013 Society for Vascular Surgery.
