Abstract
PURPOSE Locoregionally advanced HPV+ oropharyngeal squamous cell carcinoma (OPSCC) has excellent cure rates, although current treatment regimens are accompanied by acute and long-term toxicities. We designed a phase II de-escalation trial for patients with HPV+OPSCC to evaluate the feasibility of an upfront neck dissection to individualize definitive treatment selection to improve quality of life without compromising survival. METHODS Patients with T1-3, N0-2 HPV+ OPSCC underwent an upfront neck dissection with primary tumor biopsy. Patients with a single lymph node less than six centimeters, with no extracapsular spread(ECS), and no primary site adverse features underwent transoral surgery (Arm A). Patients who had two or more positive lymph nodes with no ECS, or those with primary site adverse features were treated with radiation alone (Arm B). Patients who had ECS in any lymph node were treated with chemoradiation (Arm C). The primary endpoint was quality of life at 1 year compared to a matched historical control. RESULTS Thirty-four patients were enrolled and underwent selective neck dissection. Based on pathologic characteristics, 14 patients were assigned to arm A, 10 patients to arm B, and 9 to arm C. A significant improvement was observed in HNQOL compared to historical controls (-2.6 vs -11.9, p=0.034). With a median follow-up of 37 months, the 3-year overall survival was 100% and estimated 3-year estimated progression free survival was 96% (95% CI: 76-99%). CONCLUSION A neck dissection driven treatment paradigm warrants further research as a de-intensification strategy.

Abstract
We have developed an open-source software for neuroscientists to analyze electrophysiological recordings. Named SimplyFire, the software gives the users the flexibility to analyze a variety of recordings using an interactive graphical user interface or as an importable Python package. The software features a simple plugin structure that allows users to create and deploy various electrophysiology analysis tools. SimplyFire is pre-packaged with tools commonly used in electrophysiology, such as noise filtering, trace averaging, miniature analysis, and trace exporting. We discuss in detail the algorithm behind the different features of the analysis tool. We verify the accuracy of the algorithm by testing the software using computer-generated traces with known true values of the events. SimplyFire will be distributed under the GPLv3.0 license. The open nature of this software will allow interested investigators to modify and expand the software for additional capabilities as needed. We believe this software will not only compete with commercially available software packages but will also present a powerful tool to meet the current and unmet needs of electrophysiologists.

Abstract
BACKGROUND AND PURPOSE Bioselection with induction chemotherapy in larynx cancer is associated with excellent larynx preservation and disease-specific survival but requires visual inspection of the primary tumor. We retrospectively compare clinical and imaging response in bioselected patients to develop predictive models of surgeon-assessed response (SR), laryngectomy-free survival (LFS), and overall survival (OS) in bioselected patients. MATERIALS AND METHODS In a secondary analysis of patients on two single-institution bioselection trials, model building used a regularized regression model (elastic-net) and applied nested cross-validation. Logistic regression-based model was used to predict SR and Cox proportional hazard-based models were used to predict LFS and OS. RESULTS In 115 patients with a median age of 57 years, most patients had supraglottic tumors (73.0%) and T3/T4 disease (94.8%). Definitive treatment was chemoradiation in 76.5% and laryngectomy in 23.5%. Change in primary tumor (OR = 5.78, p < 0.001) and N-classification (OR = 1.64, p = 0.003) predicted SR (AUC 0.847). Change in tumor volume (HR = 0.58, p < 0.001) predicted LFS (c-index 0.724). N-classification (HR = 1.48, p = 0.04) and pre-chemotherapy tumor volume (HR = 1.30, p = 0.174) predicted OS (c-index 0.552). CONCLUSIONS Imaging offers a non-invasive opportunity to evaluate response to induction chemotherapy, complementary to surgeon assessment. Further evaluation of approaches to bioselection that optimize generalizability of this paradigm are needed, and clinical trials utilizing imaging to predict outcomes including LFS are warranted.

Abstract
BACKGROUND Of interest is the long-term neck and shoulder impairment of patients treated with primary chemoradiotherapy (CRT). This is important for counseling patients regarding treatment decisions when discussing primary CRT. METHODS A cross-sectional study to identify factors that contribute to neck and shoulder dysfunction in patients treated with primary CRT. We utilized the neck dissection impairment index (NDII). Eighty-seven patients treated between 2003 and 2010, who were free of disease, responded; 24 of these 87 underwent post-CRT neck dissection. Mean interval since completion of CRT was over 5 years (62.7 months). Mean age, 63.5 years, male:female 75:12. RESULTS Mean NDII score was 87.4 (SD 22.1, range 5-100). Multiple linear regression revealed worse NDII scores for patients with larger pre-CRT gross tumor nodal volume (GTVnodal), controlled for age, sex, body mass index (BMI), and the presence of neck dissection (p = 0.02). There were significant associations with increasing GTVnodal and "low" scores for components of the NDII that assessed neck pain (p = 0.02), neck stiffness (p = 0.01), lifting heavy objects (p = 0.02), reaching overhead (p = 0.02), and ability to do work (p = 0.02). Physical therapy (PT) was evaluated as an "anchor" but it was prescribed "as needed." Regression revealed participation in PT was associated with higher GTVnodal, lower BMI, presence of neck dissection, and female sex (p = 0.00007). CONCLUSION GTVnodal was an independent predictor of neck and shoulder impairment. High GTVnodal was associated with increased pain and stiffness, and increased difficulty lifting heavy objects, reaching overhead, overall ability to perform work-related tasks and was associated with participation in post-treatment PT.

Abstract
OBJECTIVES Financial toxicity (FT) is a significant barrier to high-quality cancer care, and patients with head and neck cancer (HNCA) are particularly vulnerable given their need for intensive support, daily radiotherapy (RT), and management of long-term physical, functional, and psychosocial morbidities following treatment. We aim to identify predictors of FT and adverse consequences in HNCA following RT. MATERIALS AND METHODS We performed a prospective survey study of patients with HNCA seen in follow-up at an academic comprehensive cancer center (CCC) or Veterans Affairs hospital between 05/2016 and 06/2018. Surveys included validated patient-reported functional outcomes and the COST measure, a validated instrument for measuring FT. RESULTS The response rate was 86% (n = 63). Younger age and lower median household income by county were associated with lower COST scores (i.e., worse FT) on multivariable analysis (p = .045 and p = .016, respectively). Patients with worse FT were more likely to skip clinic visits (RR (95% CI) 2.13 (1.23-3.67), p = .007), be noncompliant with recommended supplements or medications (1.24 (1.03-1.48), p = .02), and require supportive infusions (1.10 (1.02-1.20), p = .02). At the CCC, patients with worse FT were more likely to require feeding tubes (1.62 (1.14-2.31), p = .007). Overall, 36% reported that costs were higher than expected, 48% were worried about paying for treatment, and 33% reported at least a moderate financial burden from treatment. CONCLUSION HNCA patients experience substantial FT from their diagnosis and/or therapy, with potential implications for medical compliance, QOL, and survivorship care.

Abstract
6085 Background: We developed and validated a prediction-score for distant metastases (DM) in major salivary gland carcinoma (SGC). Methods: Patients with SGC treated with curative-intent surgery +/- postoperative radiation therapy (PORT) at 4 tertiary cancer centers were divided into discovery (institution A&B) and validation (institution C&D) cohorts. Multivariable analysis using competing risk regression was used to identify predictors of DM in the discovery cohort and create a prediction score. The optimal score cut-off for high vs low-DM risk was determined using a minimal p-value approach. The results were subsequently evaluated in the validation cohort. The cumulative incidence and Kaplan-Meier methods were used to analyze DM and overall survival (OS), respectively. Results: Overall, 1035 patients were included (Table). In the discovery cohort, DM predictors (risk score coefficient) were: positive margin (0.6), pT3-4 (0.7), pN+ (0.7), lymphovascular invasion (LVI; 0.8), and high risk histology* (1.2). High DM-risk SGC was defined by sum of coefficients greater than 2. In the discovery cohort, the 5-year cumulative incidence of DM for high vs low risk SGC was 50% vs 8%; p < 0.01; these results were similar in the validation cohort (44% vs 4% at 5 years; p < 0.01). In the combined cohorts, this model predicted distant-only failure (40% vs 6%, p < 0.01) and late ( > 2yr post surgery) DM (22% vs 4%; p < 0.01). Patients with high DM-risk SGC had an increased incidence of DM in the subgroup receiving PORT (46% vs 8%; p < 0.01) or concurrent chemotherapy (71% vs 34%; p < 0.01). The 5-yr OS for high vs low risk SGC was 48% vs 92% (p < 0.01). Conclusions: This validated prediction score model may be used to identify SGC patients at increased risk for DM and select those who may benefit from prospective evaluation of treatment intensification and/or surveillance strategies.

Abstract
BACKGROUND The purpose of this study was to evaluate the predictive value of positron emission tomography (PET)-CT in identifying occult nodal metastasis in clinically and radiographically N0 patients with recurrent laryngeal cancer undergoing salvage laryngectomy. METHODS Retrospective review of 46 clinically and radiographically N0 patients with recurrent laryngeal cancer who underwent a PET-CT examination before salvage laryngectomy with neck dissection from January 1, 2002, to December 31, 2014, was performed. RESULTS Two patients (16.7%) had true-positive PET-CT results, whereas 10 patients (83.3%) had false-negative scans, 1 patient (2.9%) had a false-positive result and 33 patients (97.1%) had a true-negative PET-CT. The sensitivity of PET-CT was 16.7% (95% confidence interval [CI], 3.5% to 46.0%) with a specificity of 97.1% (95% CI, 83.8% to 99.9%), positive predictive value (PPV) of 66.7% (95% CI, 20.2% to 94.4%), and negative predictive value (NPV) of 76.7% (95% CI, 62.1% to 87.0%). CONCLUSION PET-CT has poor sensitivity and NPV making PET-CT an imperfect predictor of nodal disease in recurrent laryngeal cancer. © 2017 Wiley Periodicals, Inc. Head Neck 39: 980-987, 2017.

Abstract
Various retinal degenerative diseases including dry and neovascular age-related macular degeneration (AMD), retinitis pigmentosa, and diabetic retinopathy are associated with the degeneration of the retinal pigmented epithelial (RPE) layer of the retina. This consequently results in the death of rod and cone photoreceptors that they support, structurally and functionally leading to legal or complete blindness. Therefore, developing therapeutic strategies to preserve cellular homeostasis in the RPE would be a favorable asset in the clinic. The aryl hydrocarbon receptor (AhR) is a conserved, environmental ligand-dependent, per ARNT-sim (PAS) domain containing bHLH transcription factor that mediates adaptive response to stress via its downstream transcriptional targets. Using in silico, in vitro and in vivo assays, we identified 2,2′-aminophenyl indole (2AI) as a potent synthetic ligand of AhR that protects RPE cells in vitro from lipid peroxidation cytotoxicity mediated by 4-hydroxynonenal (4HNE) as well as the retina in vivo from light-damage. Additionally, metabolic characterization of this molecule by LC-MS suggests that 2AI alters the lipid metabolism of RPE cells, enhancing the intracellular levels of palmitoleic acid. Finally, we show that, as a downstream effector of 2AI-mediated AhR activation, palmitoleic acid protects RPE cells from 4HNE-mediated stress, and light mediated retinal degeneration in mice.

Abstract
Abnormalities in lysosomal function have been reported in diabetes, aging, and age-related degenerative diseases. These lysosomal abnormalities are an early manifestation of neurodegenerative diseases and often precede the onset of clinical symptoms such as learning and memory deficits; however, the mechanism underlying lysosomal dysfunction is not known. In the current study, we investigated the mechanism underlying lysosomal dysfunction in the cortex and hippocampi, key structures involved in learning and memory, of a type 2 diabetes (T2D) mouse model, the leptin receptor deficient db/db mouse. We demonstrate for the first time that diabetes leads to destabilization of lysosomes as well as alterations in the protein expression, activity, and/or trafficking of two lysosomal enzymes, hexosaminidase A and cathepsin D, in the hippocampus of db/db mice. Pioglitazone, a thiazolidinedione (TZD) commonly used in the treatment of diabetes due to its ability to improve insulin sensitivity and reverse hyperglycemia, was ineffective in reversing the diabetes-induced changes on lysosomal enzymes. Our previous work revealed that pioglitazone does not reverse hypercholesterolemia; thus, we investigated whether cholesterol plays a role in diabetes-induced lysosomal changes. In vitro, cholesterol promoted the destabilization of lysosomes, suggesting that lysosomal-related changes associated with diabetes are due to elevated levels of cholesterol. Since lysosome dysfunction precedes neurodegeneration, cognitive deficits, and Alzheimer’s disease neuropathology, our results may provide a potential mechanism that links diabetes with complications of the central nervous system.

Abstract
Diabetes and Alzheimer disease (AD)-two age-related diseases-are both increasing in prevalence, and numerous studies have demonstrated that patients with diabetes have an increased risk of developing AD compared with healthy individuals. The underlying biological mechanisms that link the development of diabetes with AD are not fully understood. Abnormal protein processing, abnormalities in insulin signaling, dysregulated glucose metabolism, oxidative stress, the formation of advanced glycation end products, and the activation of inflammatory pathways are features common to both diseases. Hypercholesterolemia is another factor that has received attention, owing to its potential association with diabetes and AD. This Review summarizes the mechanistic pathways that might link diabetes and AD. An understanding of this complex interaction is necessary for the development of novel drug therapies and lifestyle guidelines aimed at the treatment and/or prevention of these diseases.
