RESUMEN
OBJECTIVES/HYPOTHESIS: Evaluate risk factors for unplanned reoperation following free flap surgery of the head and neck. STUDY DESIGN: Retrospective database review. METHODS: The National Surgical Quality Improvement Program database was queried for free flap surgeries of the head and neck between 2010 and 2014. Bivariate and multivariate analyses were performed to compare perioperative variables and postoperative complications in patients with and without unplanned reoperation. RESULTS: A total of 1,796 patients were identified, with an overall unplanned reoperation rate of 20.0% (n = 359) within 30 days after surgery. Upon multivariate analysis, independent preoperative risk factors for unplanned reoperation include smoking (odds ratio [OR]: 1.389, 95% confidence interval [CI]: 1.042-1.850), hypertension (OR: 1.443, 95% CI: 1.096-1.901), and prior open wound/wound infection (OR: 1.675, 95% CI: 1.123-2.499). Intraoperative risk factors include prolonged operative time (OR: 1.045, 95% CI: 1.021-1.070). Surgical site infection (OR: 6.518, 95% CI: 2.728-15.574), wound disruption (OR: 17.034, 95% CI: 8.373-34.654), blood transfusion (OR: 1.561, 95% CI: 1.062-2.296), and ventilation > 48 hours (OR: 3.626, 95% CI: 1.955-6.723) were significant postoperative predictors of unplanned reoperation. CONCLUSIONS: In patients with free flap surgeries of the head and neck, preoperative smoking, hypertension, and prior open wound/wound infection, along with prolonged operative time, are risk factors for 30-day unplanned reoperation. In addition, postoperative surgical site infection, wound disruption, blood transfusion, and ventilation >48 hours are independently associated with unplanned reoperation. LEVEL OF EVIDENCE: 4 Laryngoscope, 128:2790-2795, 2018.

OBJECTIVE: Subglottic squamous cell carcinoma (SCCa) is a rare malignancy representing <5% of all laryngeal cancers. Patients often present with late-stage disease, and survival outcomes are reportedly worse than those for SCCa in other regions of the larynx. STUDY DESIGN: Analysis of a population-based tumor registry. SETTING: Academic medical center. SUBJECTS AND METHODS: The US National Cancer Institute's Surveillance, Epidemiology, and End Results database was queried for cases of subglottic SCCa from 1973 to 2011 (889 cases). Resulting data were analyzed, including patient demographics, therapeutic measures, and survival outcomes. RESULTS: Subglottic SCCa most frequently occurred in the fifth to seventh decade of life, with a mean age at diagnosis of 65.7 ± 11.3 years. There was a strong male predilection, with a male:female ratio of 3.83:1. Most patients were stage III and IV (64.4%) per the American Joint Committee on Cancer. The most common treatment modality was a combination of radiotherapy and surgery (38.8%), followed by radiotherapy alone (33.9%), and surgery alone (17.0%). Overall 5-year disease-specific survival rate was 53.7%. When stratified by treatment modality, 5-year disease-specific survival was 62.4% for surgery alone, 56.7% for radiotherapy alone, and 55.1% for surgery with adjuvant radiotherapy (P = .3892). CONCLUSION: This study represents the largest cohort of subglottic SCCa. It shows a strong predilection for men in the US population. Surgery with adjuvant radiotherapy was the most commonly employed treatment modality. No statistically significant differences were observed in 5-year DSS by treatment modality.

OBJECTIVE: Epithelial-myoepithelial carcinoma (EMC) is a rare neoplasm of the salivary glands. In this study, we aim to examine the demographic, clinicopathologic, and survival features of EMC using a population-based approach. STUDY DESIGN AND SETTING: Retrospective cohort study. SUBJECTS AND METHODS: The Surveillance, Epidemiology, and End Result (SEER) database (1973-2010) was queried for EMC of the major salivary glands. Data were analyzed with respect to various demographic and clinicopathologic factors. Survival was analyzed using the Kaplan-Meier and Cox proportional hazards models. RESULTS: In total, 246 cases were available for frequency analysis and 207 for survival analysis. Mean ± SD age at diagnosis was 63.8 ± 15.4 years. EMC affected females more frequently (57.3%). Distant metastases were present at diagnosis in only 4.5% of cases. Overall disease-specific survival (DSS) at 60, 120, and 180 months was 91.3%, 90.2%, and 80.7%, respectively. Patients with low-grade histology had significantly better survival at 180 months relative to those with high-grade tumors (90.6% vs 0.0%, P = .0246). When stratified by tumor size, patients with lesions >4 cm had the worst survival at 180 months (58.8%, P = .0003). All but 9 of the 207 cases available for survival analysis underwent surgery. A total of 85 patients (41.1%) received radiotherapy in addition to surgery. No survival benefit was noted for patients who received radiotherapy compared with those who did not (P = .4832). CONCLUSION: This report represents the largest series of EMC to date. Despite being regarded as a low-grade, indolent tumor, a significant fraction of our cohort underwent radiotherapy in addition to surgery, with no apparent added survival benefit.
