Factors Associated with Head and Neck Cancer Postoperative Radiotherapy Delays: A Systematic Review and Meta-analysis.

OBJECTIVE: Initiating postoperative radiotherapy (PORT) within 6 weeks of surgery for head and neck squamous cell carcinoma (HNSCC) is included in the National Comprehensive Cancer Network Clincal Practice Guidelines and is a Commission on Cancer quality metric. Factors associated with delays in starting PORT have not been systematically described nor synthesized. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: We included studies describing demographic characteristics, clinical factors, or social determinants of health associated with PORT delay (>6 weeks) in patients with HNSCC treated in the United States after 2003. Meta-analysis of odds ratios (ORs) was performed on nonoverlapping datasets. RESULTS: Of 716 unique abstracts reviewed, 21 studies were included in the systematic review and 15 in the meta-analysis. Study sample size ranged from 19 to 60,776 patients. In the meta-analysis, factors associated with PORT delay included black race (OR, 1.46, 95% confidence interval [CI]: 1.28-1.67), Hispanic ethnicity (OR, 1.37, 95% CI, 1.17-1.60), Medicaid or no health insurance (OR, 2.01, 95% CI, 1.90-2.13), lower income (OR, 1.38, 95% CI, 1.20-1.59), postoperative admission >7 days (OR, 2.92, 95% CI, 2.31-3.67), and 30-day hospital readmission (OR, 1.37, 95% CI, 1.29-1.47). CONCLUSION: Patients at greatest risk for a delay in initiating guideline-adherent PORT include those who are from minoritized communities, of lower socioeconomic status, and experience postoperative challenges. These findings provide the foundational evidence needed to deliver targeted interventions to enhance equity and quality in HNSCC care delivery.

Neighborhood-Level Disadvantage and Delayed Adjuvant Therapy in Head and Neck Cancer.

Importance: For patients with head and neck squamous cell carcinoma (HNSCC), initiation of postoperative radiation therapy (PORT) within 6 weeks of surgery is recommended by the National Comprehensive Cancer Network Guidelines and the Commission on Cancer. Although individual-level measures of socioeconomic status are associated with receipt of timely, guideline-adherent PORT, the role of neighborhood-level disadvantage has not been examined. Objective: To characterize the association of neighborhood-level disadvantage with delays in receiving PORT. Design, Setting, and Participants: This retrospective cohort study included 681 adult patients with HNSCC undergoing curative-intent surgery and PORT from 2018 to 2020 at 4 US academic medical centers. The data were analyzed between June 21, 2023, and March 5, 2024. Main Outcome Measures and Measures: The primary outcome was delay in initiating guideline-adherent PORT (ie, >6 weeks after surgery). Time-to-PORT (TTP) was a secondary outcome. Census block-level Area Deprivation Index (ADI) scores were calculated and reported as national percentiles (0-100); higher scores indicate greater deprivation. The association of ADI scores with PORT delay was assessed using multivariable logistic regression adjusted for demographic, clinical, and institutional characteristics. PORT initiation across ADI score population quartiles was evaluated with cumulative incidence plots and Cox models. Results: Among 681 patients with HNSCC undergoing surgery and PORT (mean [SD] age, 61.5 [11.2] years; 487 [71.5%] men, 194 [29.5%] women) the PORT delay rate was 60.8% (414/681) and median (IQR) TTP was 46 (40-56) days. The median (IQR) ADI score was 62.0 (44.0-83.0). Each 25-point increase in ADI score was associated with a corresponding 32% increase in the adjusted odds ratio (aOR) of PORT delay (aOR, 1.32; 95% CI, 1.07-1.63) on multivariable regression adjusted for institution, age, race and ethnicity, insurance, comorbidity, cancer subsite, stage, postoperative complications, care fragmentation, travel distance, and rurality. Increasing ADI score population quartiles were associated with increasing TTP (hazard ratio of PORT initiation, 0.71; 95% CI, 0.53-0.96; 0.59; 95% CI, 0.44-0.77; and 0.54; 95% CI, 0.41-0.72; for ADI quartiles 2, 3, and 4 vs ADI quartile 1, respectively). Conclusions and Relevance: Increasing neighborhood-level disadvantage was independently associated with a greater likelihood of PORT delay and longer TTP in a dose-dependent manner. These findings indicate a critical need for the development of multilevel strategies to improve the equitable delivery of timely, guideline-adherent PORT.

Delays Starting Postoperative Radiotherapy Among Head and Neck Cancer Patients: A Systematic Review and Meta-analysis.

OBJECTIVE: Initiating postoperative radiotherapy (PORT) within 6 weeks (42 days) of surgery is the first and only Commission on Cancer (CoC) approved quality metric for head and neck squamous cell carcinoma (HNSCC). No study has systematically reviewed nor synthesized the literature to establish national benchmarks for delays in starting PORT. DATA SOURCES: Following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we performed a systematic review of PubMed, Scopus, and CINAHL. REVIEW METHODS: Studies that described time-to-PORT or PORT delays in patients with HNSCC treated in the United States after 2003 were included. Meta-analysis of proportions and continuous measures was performed on nonoverlapping datasets to examine the pooled frequency of PORT delays and time-to-PORT. RESULTS: Thirty-six studies were included in the systematic review and 14 in the meta-analysis. Most studies utilized single-institution (n = 17; 47.2%) or cancer registry (n = 16; 44.4%) data. Twenty-five studies (69.4%) defined PORT delay as >6 weeks after surgery (the definition utilized by the CoC and National Comprehensive Cancer Network Guidelines), whereas 4 (11.1%) defined PORT delay as a time interval other than >6 weeks, and 7 (19.4%) characterized time-to-PORT without defining delay. Meta-analysis revealed that 48.6% (95% confidence interval [CI], 41.4-55.9) of patients started PORT > 6 weeks after surgery. Median and mean time-to-PORT were 45.8 (95% CI, 42.4-51.4 days) and 47.4 days (95% CI, 43.4-51.4 days), respectively. CONCLUSION: Delays in initiating guideline-adherent PORT occur in approximately half of patients with HNSCC. These meta-analytic data can be used to set national benchmarks and assess progress in reducing delays.

Malnutrition and Adverse Outcomes After Surgery for Head and Neck Cancer.

Importance: Patients with head and neck cancer (HNC) have an increased risk of malnutrition, partly due to disease location and treatment sequelae. Although malnutrition is associated with adverse outcomes, there is little data on the extent of outcomes and the sociodemographic factors associated with malnutrition in patients with HNC. Objectives: To investigate the association of race, ethnicity, and payer type with perioperative malnutrition in patients undergoing HNC surgery and how malnutrition affects clinical outcomes. Design, Setting, and Participants: This retrospective cohort study used data from the Premier Healthcare Database to assess adult patients who had undergone HNC surgery from January 2008 to June 2020 at 482 hospitals across the US. Diagnosis and procedure codes were used to identify a subset of patients with perioperative malnutrition. Patient characteristics, payer types, and hospital outcomes were then compared to find associations among race, ethnicity, payer type, malnutrition, and clinical outcomes using multivariable logistic regression models. Analyses were performed from August 2022 to January 2023. Exposures: Race, ethnicity, and payer type for primary outcome, and perioperative malnutrition status, race, ethnicity, and payer type for secondary outcomes. Main Outcomes and Measures: Perioperative malnutrition status. Secondary outcomes were discharge to home after surgery, hospital length of stay (LOS), total cost, and postoperative pulmonary complications (PPCs). Results: The study population comprised 13 895 adult patients who had undergone HNC surgery during the study period; they had a mean (SD) age of 63.4 (12.1) years; 9425 male (67.8%) patients; 968 Black (7.0%), 10 698 White (77.0%), and 2229 (16.0%) individuals of other races; and 887 Hispanic (6.4%) and 13 008 non-Hispanic (93.6%) individuals. Among the total sample, there were 3136 patients (22.6%) diagnosed with perioperative malnutrition. Compared with White patients and patients with private health insurance, the odds of malnutrition were higher for non-Hispanic Black patients (adjusted odds ratio [aOR], 1.31; 95% CI, 1.11-1.56), Medicaid-insured patients (aOR, 1.68; 95% CI, 1.46-1.95), and Medicare-insured patients (aOR, 1.24; 95% CI, 1.10-1.73). Black patients and patients insured by Medicaid had increased LOS, costs, and PPCs, and lower rates of discharge to home. Malnutrition was independently associated with increased LOS (ß, 5.20 additional days; 95% CI, 4.83-5.64), higher costs (ß, $15 722 more cost; 95% CI, $14 301-$17 143), increased odds of PPCs (aOR, 2.04; 95% CI, 1.83-2.23), and lower odds of discharge to home (aOR, 0.34; 95% CI, 0.31-0.38). No independent association between malnutrition and mortality was observed. Conclusions and Relevance: This retrospective cohort study found that 1 in 5 patients undergoing HNC surgery were malnourished. Malnourishment disproportionately affected Black patients and patients with Medicaid, and contributed to longer hospital stays, higher costs, and more postoperative complications.

Patient Navigation for Timely, Guideline-Adherent Adjuvant Therapy for Head and Neck Cancer: A National Landscape Analysis.

BACKGROUND: Aligned with the NCCN Clinical Practice Guidelines in Oncology for Head and Neck Cancers, in November 2021 the Commission on Cancer approved initiation of postoperative radiation therapy (PORT) within 6 weeks of surgery for head and neck cancer (HNC) as its first and only HNC quality metric. Unfortunately, >50% of patients do not commence PORT within 6 weeks, and delays disproportionately burden racial and ethnic minority groups. Although patient navigation (PN) is a potential strategy to improve the delivery of timely, equitable, guideline-adherent PORT, the national landscape of PN for this aspect of care is unknown. MATERIALS AND METHODS: From September through November 2022, we conducted a survey of health care organizations that participate in the American Cancer Society National Navigation Roundtable to understand the scope of PN for delivering timely, guideline-adherent PORT for patients with HNC. RESULTS: Of the 94 institutions that completed the survey, 89.4% (n=84) reported that at least part of their practice was dedicated to navigating patients with HNC. Sixty-eight percent of the institutions who reported navigating patients with HNC along the continuum (56/83) reported helping them begin PORT. One-third of HNC navigators (32.5%; 27/83) reported tracking the metric for time-to-PORT at their facility. When estimating the timeframe in which the NCCN and Commission on Cancer guidelines recommend commencing PORT, 44.0% (37/84) of HNC navigators correctly stated ≤6 weeks; 71.4% (60/84) reported that they did not know the frequency of delays starting PORT among patients with HNC nationally, and 63.1% (53/84) did not know the frequency of delays at their institution. CONCLUSIONS: In this national landscape survey, we identified that PN is already widely used in clinical practice to help patients with HNC start timely, guideline-adherent PORT. To enhance and scale PN within this area and improve the quality and equity of HNC care delivery, organizations could focus on providing better education and support for their navigators as well as specialization in HNC.

Lateral neck dissection surgeon volume and complications in head and neck endocrine malignancy.

Background: Increased surgeon volume is associated with decreased complications for many surgeries, including thyroidectomy. We sought to use two national databases to assess for associations between surgeon volume and complications in patients undergoing lateral neck dissection for thyroid or parathyroid malignancy. Methods: Lateral neck dissections for thyroid and parathyroid cancer from the Nationwide Inpatient Sample and State Inpatient Database were analyzed. The primary outcome was any inpatient complication common to thyroidectomy, parathyroidectomy, or lateral neck dissection. The principle independent variable was surgeon volume. Multivariable analysis was then performed on this retrospective cohort study. Results: The 1,094 Nationwide Inpatient Sample discharges had a 28% (305/1,094) complication rate. After adjustment, surgeons with volumes between 3-34 neck dissections/year demonstrated a surgeon volume-complication rate association [adjusted odds ratio: 1.03; 95% confidence interval (CI): 1.01-1.05]. The 1,235 State inpatient Database discharges had a 21% (258/1,235) overall complication rate, and no association between surgeon volume and complication rates (P=0.25). Conclusions: This retrospective review of 2,329 discharges for patients undergoing lateral neck dissection for thyroid or parathyroidectomy demonstrated somewhat conflicting results. The Nationwide Inpatient Sample demonstrated increasing complication rates for increasing surgeon volume among intermediate volume surgeons, while the State Inpatient Database demonstrated no surgeon volume-complication association. Given these disparate results, and further limitations with these databases, conclusions regarding surgical volume and clinical decision making based on these data should be assessed cautiously.

Deep-Learning-Based Screening and Ancillary Testing for Thyroid Cytopathology.

Thyroid cancer is the most common malignant endocrine tumor. The key test to assess preoperative risk of malignancy is cytologic evaluation of fine-needle aspiration biopsies (FNABs). The evaluation findings can often be indeterminate, leading to unnecessary surgery for benign post-surgical diagnoses. We have developed a deep-learning algorithm to analyze thyroid FNAB whole-slide images (WSIs). We show, on the largest reported data set of thyroid FNAB WSIs, clinical-grade performance in the screening of determinate cases and indications for its use as an ancillary test to disambiguate indeterminate cases. The algorithm screened and definitively classified 45.1% (130/288) of the WSIs as either benign or malignant with risk of malignancy rates of 2.7% and 94.7%, respectively. It reduced the number of indeterminate cases (N = 108) by reclassifying 21.3% (N = 23) as benign with a resultant risk of malignancy rate of 1.8%. Similar results were reproduced using a data set of consecutive FNABs collected during an entire calendar year, achieving clinically acceptable margins of error for thyroid FNAB classification.

Soft Tissue Trauma: Critical Recognition and Timing of Intervention in Emergency Presentations.

The facial trauma surgeon will see a variety of facial injuries. Recognition of emergency cases and proper intervention is and this article aims to highlight those cases and the respective proper interventions.

Larynx Cancer: Reconstructive Options.

Reconstruction for laryngeal cancer will depend on the defect left by surgical resection and patient-related factors such as medical comorbidities and history of previous radiation treatment. The goals of reconstruction are to preserve and/or restore the primary functions of the larynx (breathing, swallowing, voicing). Options include primary closure, locoregional flaps, and microvascular free tissue each with their advantages and disadvantages, which should be considered when planning reconstruction.

The evolution of facial reanimation techniques.

This review article provides an updated discussion on evidence-based practices related to the evaluation and management of facial paralysis. Ultimately, the goals of facial reanimation include obtaining facial symmetry at rest, providing corneal protection, restoring smile symmetry and facial movement for functional and aesthetic purposes. The treatment of facial nerve injury is highly individualized, especially given the wide heterogeneity regarding the degree of initial neuronal insult and eventual functional outcome. Recent advancements in facial reanimation techniques have better equipped clinicians to approach challenging patient scenarios with reliable, effective strategies. We discuss how technology such as machine learning software has revolutionized pre- and post-intervention assessments and provide an overview of current controversies including timing of intervention, choice of donor nerve, and management of nonflaccid facial palsy with synkinesis. We highlight novel considerations to mainstay conservative management strategies and examine innovations in modern surgical techniques with a focus on gracilis free muscle transfer. Innervation sources, procedural staging, coaptation patterns, and multi-vector and multi-muscle paddle design are modifications that have significantly evolved over the past decade.

Thyroid Cytopathology Cancer Diagnosis from Smartphone Images Using Machine Learning.

We examined the performance of deep learning models on the classification of thyroid fine-needle aspiration biopsies using microscope images captured in 2 ways: with a high-resolution scanner and with a mobile phone camera. Our training set consisted of images from 964 whole-slide images captured with a high-resolution scanner. Our test set consisted of 100 slides; 20 manually selected regions of interest (ROIs) from each slide were captured in 2 ways as mentioned above. Applying a baseline machine learning algorithm trained on scanner ROIs resulted in performance deterioration when applied to the smartphone ROIs (97.8% area under the receiver operating characteristic curve [AUC], CI = [95.4%, 100.0%] for scanner images vs 89.5% AUC, CI = [82.3%, 96.6%] for mobile images, P = .019). Preliminary analysis via histogram matching showed that the baseline model was overly sensitive to slight color variations in the images (specifically, to color differences between mobile and scanner images). Adding color augmentation during training reduces this sensitivity and narrows the performance gap between mobile and scanner images (97.6% AUC, CI = [95.0%, 100.0%] for scanner images vs 96.0% AUC, CI = [91.8%, 100.0%] for mobile images, P = .309), with both modalities on par with human pathologist performance (95.6% AUC, CI = [91.6%, 99.5%]) for malignancy prediction (P = .398 for pathologist vs scanner and P = .875 for pathologist vs mobile). For indeterminate cases (pathologist-assigned Bethesda category of 3, 4, or 5), color augmentations confer some improvement (88.3% AUC, CI = [73.7%, 100.0%] for the baseline model vs 96.2% AUC, CI = [90.9%, 100.0%] with color augmentations, P = .158). In addition, we found that our model's performance levels off after 15 ROIs, a promising indication that ROI data collection would not be time-consuming for our diagnostic system. Finally, we showed that the model has sensible Bethesda category (TBS) predictions (increasing risk malignancy rate with predicted TBS category, with 0% malignancy for predicted TBS 2 and 100% malignancy for TBS 6).

Integrated Health Maintenance Reminders for Improved HPV Vaccine Administration: Toward Improvements in Completion Disparities.

OBJECTIVE: To evaluate the effect of a health maintenance reminder (HMR) on human papillomavirus (HPV) vaccine administration and completion across different age, insurance, and race cohorts. STUDY DESIGN: Retrospective pre-post analysis. SETTING: Academic primary care. METHODS: Patients aged 9 to 26 who had initiated the HPV vaccine series from 2016 to 2021 were analyzed, based on current age-based standards. The cohort was divided based on vaccine uptake before and after the implementation of the HMR program in February 2020. The multivariate analysis estimated the odds of vaccine completion based on sociodemographic factors, and variable interactions were investigated to determine independent associations between sociodemographic factors and HMR implementation. RESULTS: There were 7654 individual patients (mean age was 15.8 years; 46.7 were males; and 50.7% were white). HPV vaccine completion rates increased post-HMR implementation by 59.2% (37% pre-, and 58.9% post-HMR; p < .001) in the entire cohort. Overall, black patients (adjusted odds ratio [aOR] = 0.68; 95% confidence interval [CI]: 0.60, 0.70) and patients ≥18 years (aOR = 0.13; 95% CI: 0.11, 0.15) were significantly less likely to complete their vaccine series; however, this improved significantly following HMR in these groups (p < .001). Post-HMR, race, and insurance status were not independently associated with disparate vaccine completion rates, however, age was, and patients ≤14 or younger had higher odds of vaccine completion (aOR = 3.54; 95% CI: 2.91, 4.32). CONCLUSION: The implementation of an HMR was associated with increased HPV vaccine uptake across age and race groups in this single-institution study. Future research should explore barriers to implementing HMRs in different health care settings.

Octreotide may improve pharyngocutaneous fistula healing through downregulation of cystatins: A pilot study.

Background: Pharyngocutaneous fistula (PCF) and salivary leaks are well known complications of head and neck surgery. The medical management of PCF has included the use of octreotide without a well-defined understanding of its therapeutic mechanism. We hypothesized that octreotide induces alterations in the saliva proteome and that these alterations may provide insight into the mechanism of action underlying improved PCF healing. We undertook an exploratory pilot study in healthy controls that involved collecting saliva before and after a subcutaneous injection of octreotide and performing proteomic analysis to determine the effects of octreotide. Methods: Four healthy adult participants provided saliva samples before and after subcutaneous injection of octreotide. A mass-spectrometry based workflow optimized for the quantitative proteomic analysis of biofluids was then employed to analyze changes in salivary protein abundance after octreotide administration. Results: There were 3076 human, 332 Streptococcus mitis, 102 G. haemolyans, and 42 Granulicatella adiacens protein groups quantified in saliva samples. A paired statistical analysis was performed using the generalized linear model (glm) function in edgeR. There were and ~300 proteins that had a p < .05 between the pre- and post-octreotide groups ~50 proteins with an FDR-corrected p < .05 between pre- and post-groups. These results were visualized using a volcano plot after filtering on proteins quantified by 2 more or unique precursors. Both human and bacterial proteins were among the proteins altered by octreotide treatment. Notably, four isoforms of the human cystatins, belonging to a family of cysteine proteases, that had significantly lower abundance after treatment. Conclusion: This pilot study demonstrated octreotide-induced downregulation of cystatins. By downregulation of cystatins in the saliva, there is decreased inhibition of cysteine proteases such as Cathepsin S. This results in increased cysteine protease activity that has been linked to enhanced angiogenic response, cell proliferation and migration that have resulted in improved wound healing. These insights provide first steps at furthering our understanding of octreotide's effects on saliva and reports of improved PCF healing.

Sociodemographic Differences in Patient-Reported Pain and Pain Management of Patients With Head and Neck Cancer in a Community Oncology Setting.

PURPOSE: While pain is prevalent among survivors of head and neck cancer (HNC), there is a lack of data on pain management in the community oncology setting. We described sociodemographic correlates and disparities associated with patient-reported pain among patients with HNC. METHODS: We used the 2017-2021 nationwide community oncology data set from Navigating Cancer, which included electronic patient-reported outcomes. We identified a retrospective cohort of patients diagnosed with HNC (N = 25,572), with ≥ 1 patient-reported pain event. We adjusted for demographic (sex, age, smoking history, marital status) and clinical (cancer site) factors associated with pain reporting and pain resolution by new pain prescription on the basis of race (White v non-White patients), using multivariate logistic regression models. RESULTS: Our analytic cohort included 2,331 patients, 90.58% White, 58.62% married, with an average age of 66.47 years. Of these, 857 patients (36.76%) reported ≥ 1 pain event during study period. Mean resolution time (in minutes) for pain incidents was significantly longer for White patients than non-White patients (99.6 ± 3.2 v 74.9 ± 7.2, P < .05). After adjusting for covariates, smoking was associated with a 25% increased odds of reporting pain incidents (adjusted odds ratio [aOR], 1.25; 95% CI, 1.03 to 1.52). There was no statistically significant difference in odds of pain reporting between White versus non-White patients (aOR, 0.97; 95% CI, 0.73 to 1.30). However, White patients were significantly more likely to receive new prescription for pain than non-White patients (aOR, 2.52; 95% CI, 1.09 to 5.86). CONCLUSION: We found racial differences in patient-reported pain management, with White patients significantly more likely to receive new pain prescriptions. As pain management is a mainstay in cancer care, equity in pain management is critical to optimize quality of life for patients with HNC.

Prediction model to estimate overall survival benefit of postoperative radiotherapy for resected major salivary gland cancers.

OBJECTIVES: To develop and validate a prediction model to estimate overall survival (OS) with and without postoperative radiotherapy (PORT) for resected major salivary gland (SG) cancers. MATERIALS AND METHODS: Adults in the National Cancer Database diagnosed with invasive non-metastatic major SG cancer between 2004 and 2015 were identified. Exclusion criteria included prior malignancy, pT1N0 or unknown stage, no or unknown surgery, and neoadjuvant therapy. Cox proportional hazards models evaluated the effect of covariates on OS. A multivariate regression model was utilized to predict 2-, 5-, and 10-year OS. Internal cross-validation was performed using 50-50 hold-out and Harrell's concordance index. RESULTS: 18,400 subjects met inclusion criteria, including 9,721 (53%) who received PORT. Distribution of SG involvement was 86% parotid, 13% submandibular, and 1% sublingual. Median follow-up for living subjects was 4.9 years. PORT was significantly associated with improved OS for the following subgroups by log-rank test: pT3 (p < 0.001), pT4 (p < 0.001), high grade (p < 0.001), node-positive (p < 0.001), and positive margin (p < 0.001). The following variables were incorporated into a multivariate model: age, sex, Charlson-Deyo comorbidity score, involved SG, pathologic T-stage, grade, margin status, ratio of nodal positivity, and PORT. The resulting model based on data from 6,138 subjects demonstrated good accuracy in predicting OS, with Harrell's concordance index of 0.73 (log-rank p < 0.001). CONCLUSION: This cross-validated prediction model estimates 2-, 5-, and 10-year differences in OS based on receipt of PORT for resected major SG cancers using readily available clinicopathologic features. Clinicians can utilize this tool to aid personalized adjuvant therapy decisions.

Surgeon Volume and Complications in Lateral Neck Dissection for Squamous Cell Carcinoma: A Multidatabase Analysis.

OBJECTIVE: To determine whether annual surgeon volume of lateral neck dissections for squamous cell carcinoma is associated with complication rates. STUDY DESIGN: Retrospective review. SETTING: Two US databases spanning 2000 to 2014. METHODS: Neck dissections for squamous cell carcinoma from the National Inpatient Sample and State Inpatient Databases were analyzed. The primary outcome was any in-hospital complication common to neck dissection. The principal independent variable was surgeon volume. A multivariable logistic generalized estimating equation with a piecewise linear spline for surgeon volume was fit to assess its association with complication. RESULTS: The National Inpatient Sample had 3517 discharges fitting criteria, a median surgeon volume of 12, and an 11.1% complication rate. A 1-unit increase in surgeon volume was associated with a 7% increase in the odds of complication when volume ranged between 4 and 19 (adjusted odds ratio [AOR], 1.07; 95% CI, 1.04-1.11) and with a 3% decrease in the odds of complication when volume ranged between 19 and 51 (AOR, 0.97; 95% CI, 0.96-0.99). The State Inpatient Databases had 2876 discharges fitting criteria, a median surgeon volume of 30, and a 13.5% complication rate. Surgeon volume was not associated with complication when <27 (AOR, 1.01; 95% CI, 0.99-1.02), but a 5-unit increase in volume was associated with a 7% decrease in the odds of complication with volume ≥27 (AOR, 0.93; 95% CI, 0.88-0.98). CONCLUSIONS: Surgeon volume was associated with complications for most volume ranges and with lower odds of complication for high-volume surgeons.

Postoperative radiotherapy is associated with improved overall survival for alveolar ridge squamous cell carcinoma with adverse pathologic features.

BACKGROUND: Alveolar ridge squamous cell carcinoma (ARSCC) is poorly represented in randomized trials. METHODS: Adults in the National Cancer Database diagnosed with ARSCC between 2010 and 2014 who should be considered for postoperative radiotherapy (PORT) based on National Comprehensive Cancer Network (NCCN)-defined risk factors were identified. RESULTS: Eight hundred forty-five (58%) of 1457 patients meeting the inclusion criteria received PORT. PORT was associated with improved overall survival (OS) on unadjusted (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.70-0.98, P = .02) and multivariable (HR 0.78, 95% CI 0.64-0.94, P = .002) analyses. PORT was associated with significantly improved 5-year OS for patients with 1 (68% vs 58%, P < .001), 2 (52% vs 31%, P < .001), and ≥3 (38% vs 24%, P < .001) NCCN-defined risk factors. Prognostic variables significantly associated with worse OS on multivariable analysis included advanced age, primary tumor size ≥3 cm, high grade, positive margin(s), stage N2-3, level IV/V nodal metastasis, and extranodal extension. CONCLUSION: PORT for resected ARSCC with adverse pathologic features is associated with significantly improved OS.

A Rare Case of a Cervical Thymic Cyst Presenting in Adulthood.

The cervical thymic cyst (CTC) is a rare, benign neck mass that most commonly presents in the pediatric population. These entities can occur anywhere along the normal path of descent of the thymus from the mandible to the sternal notch, and extension into the mediastinum has been observed. The presentation of these masses is often characterized by a painless, enlarging neck mass in a child during the first decade of life. Although most patients are asymptomatic, abutment of the cyst against local structures has led to a variety of presentations including respiratory distress. These rare lesions are noted to have a male predominance and most commonly present on the left side of the neck. We present the rare case of a 19-year-old male who presented with a left-sided painless, cystic neck mass. He underwent a computed tomography scan of the neck which showed a large cystic mass in the left neck deep to the sternocleidomastoid muscle. Preoperatively, the diagnosis of an infected third branchial cyst was favored. The lesion was completely excised in the operating room. Final pathology was consistent with a CTC. The CTC is an uncommon benign process that often presents as an asymptomatic cystic neck mass. Knowledge of the clinical presentation, diagnostic process, and treatment of these rare lesions is essential for the Otolaryngologist.
