Objective: To report a single institutional series of high-grade neuroendocrine carcinoma of the larynx (NCL), a very rare yet aggressive tumor. To review the management of NCL, including discussion of clinical behavior, treatment outcome, and prognosis. Method: A retrospective chart review of high-grade laryngeal neuroendocrine carcinomas at a single institution, including small- and large-cell neuroendocrine carcinomas. A total of 8 patients with high-grade NCL treated at our institution from 1992 to 2014 were identified. Results: The median age at diagnosis was 65.5 years (range, 43-80). Five patients were male. Two patients had a known smoking history. Primary tumor location was supraglottic in 7 patients and glottic in 1 patient. Primary treatment consisted of surgery alone (3 patients), radiotherapy alone (1 patient), combination of chemotherapy and radiotherapy (1 patient), and surgery followed by postoperative chemoradiotherapy (3 patients). Locoregional recurrence followed by distant metastasis occurred in 6 patients. Median overall survival was 44.0 months (95% CI, 3-62.0). Conclusion: High-grade NCL is a rare diagnosis. Compared to well- and moderately differentiated NCL, high-grade NCL has a far more aggressive clinical course and associated with a worse prognosis. To our knowledge, this is the largest series of patients with high-grade NCL treated at a single institution. Prompt diagnosis and multimodality therapy including elective neck dissection may improve survival.

ObjectivesWe studied the trends and predictors of drug eluting stent (DES) utilization from 2006 to 2011 to further expound the inter‐hospital variability in their utilization.BackgroundWe queried the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample (NIS) between 2006 and 2011 using ICD‐9‐CM procedure code, 36.06 (bare metal stent) or 36.07 (drug eluting stents) for Percutaneous Coronary Intervention (PCI). Annual hospital volume was calculated using unique identification numbers and divided into quartiles for analysis.Methods and ResultsWe built a hierarchical two level model adjusted for multiple confounding factors, with hospital ID incorporated as random effects in the model. About 665,804 procedures (weighted n = 3,277,884) were analyzed. Safety concerns arising in 2006 reduced utilization DES from 90% of all PCIs performed in 2006 to a nadir of 69% in 2008 followed by increase (76% of all stents in 2009) and plateau (75% in 2011). Significant between‐hospital variation was noted in DES utilization irrespective of patient or hospital characteristics. Independent patient level predictors of DES were (OR, 95% CI, P‐value) age (0.99, 0.98–0.99, <0.001), female(1.12, 1.09–1.15, <0.001), acute myocardial infarction(0.75, 0.71–0.79, <0.001), shock (0.53, 0.49–0.58, <0.001), Charlson Co‐morbidity index (0.81,0.77–0.86, <0.001), private insurance/HMO (1.27, 1.20–1.34, <0.001), and elective admission (1.16, 1.05–1.29, <0.001). Highest quartile hospital (1.64, 1.25–2.16, <0.001) volume was associated with higher DES placement.ConclusionThere is significant between‐hospital variation in DES utilization and a higher annual hospital volume is associated with higher utilization rate of DES. © 2015 Wiley Periodicals, Inc.

Abstract Pretreatment evaluation is performed to determine the number, location, and size of the brain metastases and magnetic resonance imaging (MRI) is the recommended imaging technique, particularly in patients being considered for surgery or stereotactic radiosurgery. A contiguous thin-cut volumetric MRI with gadolinium with newer gadolinium-based agents can improve detection of small brain metastases. A systemic workup and medical evaluation are important, given that subsequent treatment for the brain metastases will also depend on the extent of the extracranial disease and on the age and performance status of the patient. Patients with hydrocephalus or impending brain herniation should be started on high doses of corticosteroids and evaluated for possible neurosurgical intervention. Patients with moderate symptoms should receive approximately 4–8 mg/d of dexamethasone in divided doses. The routine use of corticosteroids in patients without neurologic symptoms is not necessary. There is no proven benefit of anticonvulsants in patient without seizures. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 3 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Objectives: We evaluated relapse patterns after transoral laser microsurgery (TLM) in squamous cell carcinoma (SCC) of the tonsil and tongue base and evaluated the indications for adjuvant irradiation. Methods: Between December 1, 1996, and December 31, 2005, 79 patients with previously untreated SCC of the tonsil or tongue base underwent TLM with or without neck dissection. Thirty-eight patients (48%) underwent postoperative irradiation (median, 62 Gy) to the primary site and the neck. Analysis of relapse patterns was performed on the basis of adverse risk factors and the presence or absence of adjuvant irradiation. Results: The median follow-up for living patients was 47 months (range, 10 to 107 months), and patients were monitored for at least 2 years or until recurrence or death. Local, regional, and distant treatment failures numbered 4, 6, and 4 for surgery alone (n = 41) and 0, 2, and 6 for adjuvant irradiation (n = 38), respectively. Patients with high-risk features (extracapsular extension or at least 2 adverse factors) had locoregional control rates at 2 or more years of 66% and 94% for TLM alone and TLM plus adjuvant irradiation, respectively. Conclusions: Adjuvant irradiation after TLM resection of oropharyngeal SCC with intermediate- or high-risk features improves locoregional control compared with TLM alone.

BackgroundThe purpose of this study was to report the treatment outcomes of patients with advanced oropharyngeal cancer treated with transoral laser microsurgery (TLM) followed by radiation therapy (RT) at Mayo Clinic in Arizona.MethodsA retrospective study of 80 patients treated from January 1, 2000 to November 7, 2011 was performed. All patients had stage III/IV oropharyngeal tumors and underwent TLM with neck dissection. Adjuvant RT was then given. Thirty‐seven patients received concurrent adjuvant chemotherapy. The primary outcome was locoregional control.ResultsMedian follow‐up was 47.3 months (range, 9.7–139.2 months). The 3‐year locoregional control, recurrence‐free survival, and overall survival rates were 98.6% (95% confidence interval [CI], 91% to 100%), 91.1% (95% CI, 81% to 96%), and 93.7% (95% CI, 84% to 98%), respectively. There were a total of 5 treatment failures, 1 regional and 4 distant. Twenty‐six patients underwent neck only RT with exclusion of the primary site.ConclusionTLM followed by RT for advanced oropharyngeal cancer results in excellent locoregional control rates. © 2013 Wiley Periodicals, Inc.
