Factors Associated With Risk of Body Image-Related Distress in Patients With Head and Neck Cancer.

Importance: Body image-related distress (BID) is common among head and neck cancer (HNC) survivors and associated with significant morbidity. Risk factors for HNC-related BID remain poorly characterized because prior research has used outcome measures that fail to fully capture BID as experienced by HNC survivors. Objective: To assess the association of demographic and oncologic characteristics with HNC-related BID using the Inventory to Measure and Assess imaGe disturbancE-Head & Neck (IMAGE-HN), a validated, multidomain, patient-reported outcome measure of HNC-related BID. Design, Setting, and Participants: This cross-sectional study assessed 301 adult survivors of surgically managed HNC at 4 academic medical centers. Main Outcomes and Measures: The primary outcome measure was IMAGE-HN scores, for which higher scores reflect more severe HNC-related BID. Multivariable linear regression analyses were performed to evaluate the association of patient characteristics with IMAGE-HN global and 4 subdomain (other-oriented appearance concerns, personal dissatisfaction with appearance, distress with functional impairments, and social avoidance) scores. Results: Of the 301 participants (212 [70.4%] male; mean [SD] age, 65.3 [11.7] years), 181 (60.1%) underwent free flap reconstruction. Graduation from college (ß = -9.6; 95% CI, -17.5 to -1.7) or graduate school (ß = -12.6; 95% CI, -21.2 to -3.8) was associated with lower IMAGE-HN social avoidance scores compared with less than a high school education. Compared with paid work, unemployment was associated with higher IMAGE-HN other-oriented appearance (ß = 10.7; 95% CI, 2.0-19.3), personal dissatisfaction with appearance (ß = 12.5; 95% CI, 1.2-23.7), and global (ß = 8.0; 95% CI, 0.6-15.4) scores. Compared with no reconstruction, free flap reconstruction was associated with higher IMAGE-HN global scores (ß = 11.5; 95% CI, 7.9-15.0) and all subdomain scores (other-oriented appearance: ß = 13.1; 95% CI, 8.6-17.6; personal dissatisfaction with appearance: ß = 15.4; 95% CI, 10.0-20.7; distress with functional impairment: ß = 12.8; 95% CI, 8.1-17.4; and social avoidance and isolation: ß = 10.2; 95% CI, 5.8-14.6). Higher IMAGE-HN distress with functional impairment scores were found in those who received surgery and adjuvant radiation (ß = 7.8; 95% CI, 2.9-12.7) or chemoradiotherapy (ß = 6.5; 95% CI, 1.8-11.3) compared with surgery alone. The multivariable regression model accounted for a modest proportion of variance in IMAGE-HN global (R2 = 0.18) and subdomain scores (R2 = 0.20 for other-oriented appearance, 0.14 for personal dissatisfaction with appearance, 0.21 for distress with functional impairment, and 0.13 for social avoidance and isolation). Conclusions and Relevance: In this cross-sectional study, factors associated with risk of HNC-related BID included free flap reconstruction, lower educational attainment, unemployment, and multiple treatment modalities. These characteristics explain a modest proportion of variance in IMAGE-HN scores, suggesting that other characteristics may be the major risk factors for HNC-related BID and should be explored in future studies.

Free Flap Inset Techniques in Salvage Laryngopharyngectomy Repair: Impact on Fistula Formation and Function.

OBJECTIVE: To characterize pharyngocutaneous fistula (PCF) rates and functional outcomes following microvascular free tissue transfer (MVFTT) reconstruction of salvage total laryngectomy (STL) with a review of two different flap inset techniques and a review of the literature. METHODS: Retrospective review. RESULTS: Review of the literature revealed 887 patients who underwent STL MVFTT from 14 references. Ninety-six STL MVFTTs were performed by the authors, with 36 (38%) patients undergoing multilayer fascial underlay (MLFU) closure and 60 (62%) a standard single layer closure (SLC). One (3%) PCF occurred in the MLFU group compared to 12 (20%) in the SLC cohort (P = .03). Postoperative gastrostomy (G)-tube dependence was lower following MLFU closure compared to SLC (25% vs. 57%, P < .01), whereas pharyngoesophageal stricture (PES) (28% vs. 38%), tracheoesophageal puncture (TEP) placement (42% vs. 42%), and TEP usage (87% vs. 88%) did not significantly differ (P > .05). Compared to pooled rates from the literature, patients who underwent a MLFU MVFTT inset technique demonstrated significantly lower PCF incidence (3% vs. 23%, P < .01) without significant differences in PES (28% vs 23%, P = .55), G-tube dependence (25% vs. 23%, P = .25), or TEP placement (42% vs. 59%, P = .09). CONCLUSION: Despite MVFTT reconstruction after STL, G-tube dependence, PCF formation, and limitations of speaking rehabilitation (TEP) remain a significant issue. Modification of MVFTT inset may provide an opportunity to reduce PCF incidence without affecting other functional outcomes. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E875-E881, 2021.

Validation of a Novel, Multidomain Head and Neck Cancer Appearance- and Function-Distress Patient-Reported Outcome Measure.

OBJECTIVES: Distress with self-perceived changes in appearance and function can result in body image disturbance (BID), which is common in head and neck cancer (HNC) survivors and a major source of psychosocial morbidity. To address the lack of psychometrically sound patient-reported outcome measures (PROMs) of HNC-related BID, we aim to create and validate the Inventory to Measure and Assess imaGe disturbancE-Head & Neck (IMAGE-HN). STUDY DESIGN: Survey study. SETTING: Multiple academic centers. SUBJECTS AND METHODS: Following item development, HNC survivors from 4 academic centers completed the IMAGE-HN. Item responses were psychometrically analyzed using confirmatory factor analysis (CFA) and Rasch analysis. RESULTS: Item development resulted in a 31-item PROM consisting of 5 individual domains and a global domain. In total, 305 HNC survivors of diverse ages, HNC subsites, and reconstructive paradigms completed the initial items. After removal of 3 items for local dependence, CFA confirmed the unidimensionality and local independence (item residual correlations <|0.20|) for each domain. Rasch analysis indicated acceptable fit (infit and outfit mean squares <2.0), monotonicity of all rating scale categories, and low person misfit (<4%). Person separation indices and person reliability were adequate for each domain except appearance concealment, which was removed (4 items). This resulted in the IMAGE-HN, a psychometrically acceptable 24-item PROM of HNC-related BID consisting of a global scale and 4 subscales measuring unique constructs and comprised independent items. CONCLUSIONS: IMAGE-HN is a novel, psychometrically sound, multidomain PROM of HNC-related BID for use in clinical and research settings.

Association of Medicaid Expansion Under the Affordable Care Act With Stage at Diagnosis and Time to Treatment Initiation for Patients With Head and Neck Squamous Cell Carcinoma.

Importance: Medicaid expansions as part of the Patient Protection and Affordable Care Act (ACA) are associated with decreases in the percentage of uninsured patients who have received a new diagnosis of cancer. Little is known about the association of Medicaid expansions with stage at diagnosis and time to treatment initiation (TTI) for patients with head and neck squamous cell carcinoma (HNSCC). Objective: To determine the association of Medicaid expansions as part of the ACA with stage at diagnosis and TTI for patients with HNSCC. Design, Setting, and Participants: A retrospective cohort study was conducted at Commission on Cancer-accredited facilities among 90 789 patients identified from the National Cancer Database aged 18 to 64 years with HNSCC that was diagnosed during the period from January 1, 2010, to December 31, 2016. Statistical analysis was conducted from February 18 to November 8, 2019. Main Outcomes and Measures: Outcome measures included health insurance coverage, stage at diagnosis, and TTI. Absolute percentage change in health insurance coverage, crude and adjusted difference in differences (DD) in absolute percentage change in coverage, stage at diagnosis, and TTI before (2010-2013) and after (2014-2016) ACA implementation were calculated for Medicaid expansion and nonexpansion states. Results: Of the 90 789 nonelderly adults with newly diagnosed HNSCC (mean [SD] age, 54.7 [7.0] years), 70 907 (78.1%) were men, 72 911 (80.3%) were non-Hispanic white, 52 142 (57.4%) were between 55 and 64 years of age, and 54 940 (60.5%) resided in states with an ACA Medicaid expansion. Compared with nonexpansion states, the percentage of patients with HNSCC with Medicaid increased more in expansion states after the implementation of the ACA (adjusted DD, 4.6 percentage points [95% CI, 3.7-5.4 percentage points]). The percentage of patients with localized disease (American Joint Committee on Cancer stage I-II) at diagnosis increased in expansion states compared with nonexpansion states for the overall cohort (adjusted DD, 2.3 percentage points [95% CI, 1.1-3.5 percentage points]) and for the subset of patients with nonoropharyngeal HNSCC (adjusted DD, 3.4 percentage points [95% CI, 1.5-5.2 percentage points]). The mean TTI did not differ between expansion and nonexpansion states for the cohort (adjusted DD, -12.7 percentage points [95% CI, -27.4 to 4.2 percentage points]) but improved for patients with nonoropharyngeal HNSCC (adjusted DD, -26.5 percentage points [95% CI, -49.6 to -3.4 percentage points]). Conclusions and Relevance: This study suggests that Medicaid expansions were associated with a greater increase in the percentage of patients with HNSCC with Medicaid coverage, an increase in the percentage of patients with localized disease at diagnosis for the overall cohort of patients with HNSCC, and improved TTI for patients with nonoropharyngeal HNSCC.

Wilderness Medical Society Clinical Practice Guidelines for the Prevention and Treatment of Heat Illness: 2019 Update.

The Wilderness Medical Society convened an expert panel in 2011 to develop a set of evidence-based guidelines for the recognition, prevention, and treatment of heat illness. We present a review of the classifications, pathophysiology, and evidence-based guidelines for planning and preventive measures, as well as best practice recommendations for both field- and hospital-based therapeutic management of heat illness. These recommendations are graded based on the quality of supporting evidence and balance the benefits and risks or burdens for each modality. This is an updated version of the original Wilderness Medical Society Practice Guidelines for the Treatment and Prevention of Heat-Related Illness published in 2013.

Body Image Disturbance in Surgically Treated Head and Neck Cancer Patients: A Patient-Centered Approach.

OBJECTIVE: To promote patient-centered oncology care through an in-depth analysis of the patient experience of body image disturbance (BID) following surgery for head and neck cancer (HNC). STUDY DESIGN: Qualitative methods approach using semistructured key informant interviews. SETTING: Academic medical center. SUBJECTS AND METHODS: Participants with surgically treated HNC underwent semistructured key informant interviews and completed a sociodemographic survey. Recorded interviews were transcribed, coded, and analyzed using template analysis to inform creation of a conceptual model. RESULTS: Twenty-two participants with surgically treated HNC were included, of whom 16 had advanced stage disease and 15 underwent free tissue transfer. Five key themes emerged characterizing the participants' lived experiences with BID following HNC treatment: personal dissatisfaction with appearance, other-oriented appearance concerns, appearance concealment, distress with functional impairments, and social avoidance. The participant's perceived BID severity was modified by preoperative patient expectations, social support, and positive rational acceptance. These 5 key themes and 3 experiential modifiers form the basis of a novel, patient-centered conceptual model for understanding BID in HNC survivors. CONCLUSION: A patient-centered approach to HNC care reveals that dissatisfaction with appearance, other-oriented appearance concerns, appearance concealment, distress with functional impairments, and social avoidance are key conceptual domains characterizing HNC-related BID. Recognition of these psychosocial dimensions of BID in HNC patients can inform development of HNC-specific BID patient-reported outcome measures to facilitate quantitative assessment of BID as well as the development of novel preventative and therapeutic strategies for those at risk for, or suffering from, BID.

A Systematic Review of Patient-Reported Outcome Measures Assessing Body Image Disturbance in Patients with Head and Neck Cancer.

OBJECTIVE: To synthesize published literature describing the severity of body image disturbance (BID) in patients with head and neck cancer (HNC) over time, its psychosocial and functional associations, and treatment strategies as assessed by patient-reported outcome measures (PROMs). DATA SOURCE: PubMed/MEDLINE, Scopus, PsycINFO, Web of Science, and Google Scholar. REVIEW METHODS: A systematic review of the English-language literature was performed to identify studies of BID in patients with HNC using psychometrically validated PROMs to assess (1) severity of BID over time, (2) psychosocial and functional associations, and (3) management strategies. RESULTS: A total of 17 studies met inclusion criteria. BID was assessed via 10 different PROMs, none of which were HNC-specific measures of BID. Two of 2 longitudinal studies (100%) reported that BID improved from pretreatment to posttreatment, and 2 of 3 longitudinal studies (67%) showed that the severity of BID decreased over time as survivors got further out from treatment. Seven of 17 studies (41%) described negative functional and psychosocial associations with BID, although study methodology limited conclusions about cause and effect. None of the studies assessing interventions to manage BID (0/2, 0%) demonstrated an improvement in BID relative to control. CONCLUSION: BID in patients with HNC has negative functional and psychosocial associations and lacks evidence-based treatment. Research is limited by the lack of an HNC-specific BID PROM. Further research should address knowledge gaps related to the lack of an HNC-specific BID PROM, longitudinal course of BID in patients with HNC, confusion with regards to risk factors and outcomes, and lack of prevention and treatment strategies.

A Comparison of the NCDB and SEER Database for Research Involving Head and Neck Cancer.

OBJECTIVE: To determine whether structural differences in data sampling between the National Cancer Database (NCDB), a non-population-based cancer registry, and Surveillance, Epidemiology, and End Results (SEER), a population-based cancer registry, result in differences in patient characteristics or oncologic outcomes. STUDY DESIGN: Retrospective cohort study. SETTING: NCDB and SEER database. SUBJECTS AND METHODS: Patients with head and neck cancer (HNC) were included from 2004 to 2014. The primary outcome, weighted differences in characteristics between the databases, was evaluated for each head and neck subsite (oral cavity [OC], oropharynx [OP], hypopharynx [HP], and larynx [LX]). The secondary outcome measure, overall survival (OS), was evaluated using Kaplan-Meier (KM) estimates of survival and Cox proportional hazards (PH) regression modeling. RESULTS: In total, 112,007 and 340,420 HNC cases were registered in SEER and the NCDB, respectively. The mean age at diagnosis for the 4 head and neck subsites differed by no more than 1.1 years between the 2 databases. The largest difference in patient or tumor characteristics was the frequency of OC subsite lip cancer (weighted proportional difference, 6.9%; 95% confidence interval, 6.5%-7.3%). Unadjusted KM estimates of 5-year OS differed by no more than 2% (OP, HP, and LX subsites). On Cox PH modeling, adjusted hazard ratios ranged from 0.89 to 0.91 for patients of different head and neck subsites in the NCDB relative to SEER. CONCLUSIONS: Patients with HNC in the SEER database and NCDB do not greatly differ in terms of demographics, treatment, and survival. Decisions to use either database should be driven by the data fields, which vary between the registries.

Analysis of 334 Cases of Pediatric Esophageal Foreign Body Removal Suggests that Traditional Methods Have Similar Outcomes Whereas a Magnetic Tip Orogastric Tube Appears to Be an Effective, Efficient, and Safe Technique for Disc Battery Removal.

Procedures and outcomes for pediatric esophageal foreign body removal were analyzed. Traditional methods of battery removal were compared with a magnetic tip orogastric tube (MtOGT). A single institution retrospective review from 1997 to 2014 of pediatric patients with esophageal foreign bodies was performed. Balloon extraction with fluoroscopy (performed in 173 patients with 91% success), flexible endoscopy (92% success in 102 patients), and rigid esophagoscopy (95% in 38 patients) had excellent success rates. A MtOGT had 100 per cent success in six disc battery patients, when other methods were more likely to fail, and was the fastest. Power analysis suggested 20 patients in the MtOGT group would be needed for significant savings in procedural time. Thirty-two per cent of all foreign bodies and 95 per cent of batteries had complications (P = 0.002) because of the foreign body. Overall, 1.2 per cent had severe complications, whereas 10 per cent of batteries had severe complications (P = 0.04). Each technique if applied appropriately can be a reasonable option for esophageal foreign body removal. Magnetic tip orogastric tubes used to extract ferromagnetic objects like disc batteries had the shortest procedure time and highest success rate although it was not statistically significant. Disc batteries require emergent removal and have a significant complication rate.

Racial and Ethnic Disparities in Travel for Head and Neck Cancer Treatment and the Impact of Travel Distance on Survival.

BACKGROUND: Patients who travel a long distance (≥50 miles) for cancer care have improved outcomes. However, to the authors' knowledge, the prevalence of long travel distances for treatment by patients with head and neck squamous cell carcinoma (HNSCC), and the effect of travel distance on overall survival (OS), remains unknown. METHODS: The authors used the National Cancer Data base from 2004 through 2013 to identify patients with HNSCC undergoing definitive treatment. Travel distance for treatment was categorized as short (<12.5 miles), intermediate (12.5-49.9 miles), and long (50-249.9 miles). The primary outcome, OS, was evaluated using Cox shared-frailty modeling. A secondary outcome, factors associated with intermediate and long travel distances, was evaluated using multivariable hierarchical logistic regression. RESULTS: Among 118,000 patients with HNSCC, 62,753 (53.2%), 40,644 (34.4%), and 14,603 (12.4%) patients, respectively, traveled short, intermediate, and long distances for treatment. After adjusting for relevant covariates, long travel distance was associated with treatment at academic and high-volume centers. Patients of black race, of Hispanic ethnicity, with Medicaid insurance, and who were treated with nonsurgical treatment were less likely to travel long distances for treatment (P<.001). Traveling a long distance for treatment was associated with improved OS on multivariable analysis (adjusted hazard ratio, 0.93; 95% confidence interval, 0.89-0.96) compared with a short distance. CONCLUSIONS: Traveling a long distance for HNSCC treatment is associated with improved survival, especially for patients receiving nonsurgical management. Racial and ethnic disparities in travel for HNSCC treatment exist. As regionalization of care continues, future work should identify and address reasons for racial and ethnic disparities in travel that may prevent access to care at high-volume facilities.

Computational analysis of swallowing mechanics after surgery for obstructive sleep apnea.

Multilevel upper airway surgery for obstructive sleep apnea (OSA) has been shown to cause clinically significant dysphagia in some patients. We describe the cases of 2 adults with OSA who developed persistent dysphagia after multilevel upper airway surgery. Patient-specific computational analysis of swallowing mechanics (CASM) revealed absent pharyngeal shortening and aberrant tongue base retraction in both patients. These findings are consistent with the OSA surgical goal of enlarging the hypopharyngeal airway but likely contributed to our patients' dysphagia. Patient-specific CASM allows for sensitive identification of swallowing mechanical dysfunction that might otherwise be overlooked, and it may be utilized in future head and neck surgery patients to analyze swallowing dysfunction associated with treatment.

Predictors of contralateral-bilateral nodal disease in oropharyngeal cancer: A National Cancer Data Base Study.

BACKGROUND: Oropharyngeal squamous cell carcinoma (SCC) frequently presents with cervical metastasis. Roles of human papillomavirus (HPV) status, among other factors, on laterality are elusive. METHODS: The National Cancer Database was reviewed for oropharyngeal SCC diagnosed from 2010-2014. Predictors of clinically evident contralateral or bilateral nodal disease were identified. RESULTS: A total of 15 517 patients with oropharyngeal SCC met criteria. The majority was HPV-positive. Histologically poorly differentiated tumors were more frequent in the HPV-positive group (55.7% vs 37.6%; P < .001). By incidence, there was no statistical difference in contralateral or bilateral nodal disease between HPV-positive and HPV-negative patients (14.2% vs 14.5%, respectively; P = .769). On multivariable analysis, notable predictors of contralateral or bilateral nodal disease included HPV-positivity (odds ratio [OR] 1.26; 99% confidence interval [CI] 1.10-1.44), base of tongue (BOT) location (OR 2.15; 99% CI 1.88-2.45), poorly differentiated tumor (OR 1.72; 99% CI 1.20-2.46), and T4 classification (OR 6.65; 99% CI 5.34-8.28). CONCLUSION: Patients with HPV-associated oropharyngeal SCC have increased likelihood of contralateral or bilateral nodal disease. Tumor grade, tumor location, and tumor size are also independent predictors.

Primary Surgery vs Radiotherapy for Early Stage Oral Cavity Cancer.

Objective The goal of this study is to determine the effect of primary surgery vs radiotherapy (RT) on overall survival (OS) in patients with early stage oral cavity squamous cell carcinoma (OCSCC). In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

Effect of time to initiation of postoperative radiation therapy on survival in surgically managed head and neck cancer.

BACKGROUND: The objective of this study was to determine the effects of National Comprehensive Cancer Network (NCCN) guideline-adherent initiation of postoperative radiation therapy (PORT) and different time-to-PORT intervals on the overall survival (OS) of patients with head and neck squamous cell carcinoma (HNSCC). METHODS: The National Cancer Data Base was reviewed for the period of 2006-2014, and patients with HNSCC undergoing surgery and PORT were identified. Kaplan-Meier survival estimates, Cox regression analysis, and propensity score matching were used to determine the effects of initiating PORT within 6 weeks of surgery and different time-to-PORT intervals on survival. RESULTS: This study included 41,291 patients. After adjustments for covariates, starting PORT >6 weeks postoperatively was associated with decreased OS (adjusted hazard ratio [aHR], 1.13; 99% confidence interval [CI], 1.08-1.19). This finding remained in the propensity score-matched subset (hazard ratio, 1.21; 99% CI, 1.15-1.28). In comparison with starting PORT 5 to 6 weeks postoperatively, initiating PORT earlier was not associated with improved survival (aHR for ≤ 4 weeks, 0.93; 99% CI, 0.85-1.02; aHR for 4-5 weeks, 0.92; 99% CI, 0.84-1.01). Increasing durations of delay beyond 7 weeks were associated with small, progressive survival decrements (aHR, 1.09, 1.10, and 1.12 for 7-8, 8-10, and >10 weeks, respectively). CONCLUSIONS: Nonadherence to NCCN guidelines for initiating PORT within 6 weeks of surgery was associated with decreased survival. There was no survival benefit to initiating PORT earlier within the recommended 6-week timeframe. Increasing durations of delay beyond 7 weeks were associated with small, progressive survival decrements. Cancer 2017;123:4841-50. © 2017 American Cancer Society.

Prognostic factors and occult nodal disease in mucoepidermoid carcinoma of the oral cavity and oropharynx: An analysis of the National Cancer Database.

OBJECTIVES: Mucoepidermoid carcinoma (MEC) is an uncommon malignancy that most commonly occurs in the parotid gland followed by the minor salivary glands of the upper aerodigestive tract, most notably in the oral cavity (OC) and oropharynx (OP). Because of its rarity, few studies have been performed that are specific to MEC within the OC and OP. The objective of this study is to describe the tumor characteristics and prognostic features for MEC of the OC and OP. MATERIALS AND METHODS: The National Cancer Database (NCDB) was used for this study. The primary outcome measure was 5-year overall survival (OS). The secondary outcome measure was occult nodal disease. Fischer's exact tests, chi-square tests, log-rank tests and Cox proportional hazards analyses were performed. RESULTS: We identified 3005 patients with MEC of the OC/OP. The 5-year overall survival for MEC of the OC and OP was 87%. Increasing age, male sex, Charlson/Deyo comorbidity score of 2+, clinical T3-4 tumors, nodal+disease, high grade tumors and positive margins were independently associated with decreased 5-year OS. Occult nodal disease occurred in 14.1% and 17.3% of high grade and clinical T3-T4 tumors respectively. CONCLUSION: MEC of the OC/OP has an excellent survival as the majority of these patients have low/intermediate grade and early stage disease. Negative prognosticators include increasing age, male sex, Charlson/Deyo comorbidity score of 2+, clinical T3-4 tumors, nodal+ disease, high grade tumors and positive margins. Our findings justify strong consideration of prophylactic neck dissection for high grade and clinical T3-4 tumors.

Ewing Sarcoma of the Head and Neck.

OBJECTIVES: Ewing sarcoma is a rare tumor of the head and neck. Previous efforts to characterize Ewing sarcoma of the head and neck (ES-HN) have been limited to small retrospective series. The objective of this study was to analyze the demographic, clinicopathologic, treatment, and survival characteristics of ES-HN compared to Ewing sarcoma at other locations (ES-other). METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database, we compared 183 patients with ES-HN to 3177 patients with ES-other. Patient characteristics were analyzed with chi-square or t test. Ten-year disease-specific survival (DSS) and overall survival (OS) were estimated via the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox regression analysis was used to determine if HN location was an independent prognosticator. RESULTS: The ES-HN displayed a lower tumor size ( P < .001) and metastatic rate ( P < .001) compared to ES-other. The ES-HN had a better 10-year DSS and OS than ES-other ( P = .001, P = .015, respectively). The HN location did not achieve statistical significance on multivariate Cox regression analysis ( P = .88). CONCLUSION: ES-HN does not appear to be a separate clinical entity compared to ES-other; rather, its associated improved prognosis is likely secondary to its smaller size and lower metastatic rate compared to ES-other.

Head and neck chondrosarcomas: Analysis of the Surveillance, Epidemiology, and End Results database.

BACKGROUND: Chondrosarcoma is a rare tumor of the head and neck. Because of the limited clinical data, no studies have conducted a thorough comparison between head and neck chondrosarcomas and those arising at other body sites. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database, we compared 682 patients with chondrosarcomas of the head and neck with 4757 patients with non-head and neck chondrosarcomas, evaluating disease-specific survival (DSS) and overall survival (OS) based on tumor location, histology, grade, stage, and treatment. RESULTS: Head and neck chondrosarcomas displayed a lower grade (p < .001) and stage (p < .0001) compared with other chondrosarcomas. Overall, chondrosarcomas of the head and neck had significantly higher DSS and OS than non-head and neck chondrosarcomas (p < .001). CONCLUSION: Chondrosarcomas of the head and neck display a lower grade and stage compared with other chondrosarcomas. DSS and OS were significantly greater for chondrosarcomas of the head and neck. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1359-1366, 2016.

A prospective randomized blister prevention trial assessing paper tape in endurance distances (Pre-TAPED).

OBJECTIVE: Friction foot blisters are a common injury occurring in up to 39% of marathoners, the most common injury in adventure racing, and represent more than 70% of medical visits in multi-stage ultramarathons. The goal of the study was to determine whether paper tape could prevent foot blisters in ultramarathon runners. METHODS: This prospective randomized trial was undertaken during RacingThePlanet 155-mile (250-km), 7-day self-supported ultramarathons in China, Australia, Egypt, Chile, and Nepal in 2010 and 2011. Paper tape was applied prerace to one randomly selected foot, with the untreated foot acting as the own control. The study end point was development of a hot spot or blister on any location of either foot. RESULTS: One hundred thirty-six participants were enrolled with 90 (66%) having completed data for analysis. There were 36% women, with a mean age of 40 ± 9.4 years (range, 25-40 years) and pack weight of 11 ± 1.8 kg (range, 8-16 kg). All participants developed blisters, with 89% occurring by day 2 and 59% located on the toes. No protective effect was observed by the intervention (47 versus 35; 52% versus 39%; P = .22), with fewer blisters occurring around the tape on the experimental foot than under the tape (23 vs 31; 25.6% versus 34.4%), yet 84% of study participants when queried would choose paper tape for blister prevention in the future. CONCLUSIONS: Although paper tape was not found to be significantly protective against blisters, the intervention was well tolerated with high user satisfaction.

Wilderness Medical Society practice guidelines for the prevention and treatment of heat-related illness: 2014 update.

The Wilderness Medical Society (WMS) convened an expert panel to develop a set of evidence-based guidelines for the recognition, prevention, and treatment of heat illness. We present a review of the classifications, pathophysiology, and evidence-based guidelines for planning and preventive measures as well as best practice recommendations for both field and hospital-based therapeutic management of heat illness. These recommendations are graded on the basis of the quality of supporting evidence, and balance between the benefits and risks or burdens for each modality. This is an updated version of the original WMS Practice Guidelines for the Prevention and Treatment of Heat-Related Illness published in Wilderness & Environmental Medicine 2013;24(4):351-361.
