BACKGROUND:There are several options for primary surgical treatment of early-stage supraglottic squamous cell carcinoma (SCC), including transoral robotic surgery (TORS). The purpose of this study was to compare outcomes of TORS to open partial laryngectomy and transoral laser microsurgery (TLM). METHODS:Patients with clinical classification T1-2 supraglottic SCC diagnosed 2010-2019, treated with TORS, open partial laryngectomy, or TLM in the National Cancer Database were selected. RESULTS:One thousand six hundred three patients were included: 17% TORS, 26.5% TLM, 56.5% open. TORS patients had the lowest rates of adjuvant treatment (28.4% vs. TLM: 45.0%, open: 38.5%, p < 0.001), and lower positive margin rates than TLM (16.9% vs. 30.5%, p < 0.001). Thirty-day and ninety-day post-operative mortality did not differ between the approaches. Five-year survival was higher following TORS compared to open surgery (77.8% vs. 66.1%, p = 0.01); this difference persisted following matched-pair analysis. CONCLUSIONS:TORS may be a safe and effective surgical approach for early-stage supraglottic SCC in appropriate patients.

OBJECTIVE:Sinonasal cancer often presents as locoregionally advanced disease. National guidelines recommend management of stage T4b tumors with systemic therapy and radiotherapy, but recent studies suggest that including surgical resection in the multimodal treatment of these tumors may improve local control and survival. We queried the National Cancer Database to examine patterns of care and outcomes in T4b sinonasal squamous cell carcinoma (SCC). STUDY DESIGN/METHODS:Prospectively gathered data. SETTING/METHODS:National Cancer Database. METHODS:Patients with T4b N0-3 M0 sinonasal squamous cell carcinoma diagnosed in 2004 to 2016 were stratified between those who received chemoradiotherapy and those who underwent surgical resection with neoadjuvant or adjuvant treatment. The overall survival of each cohort was assessed via Kaplan-Meier analysis and Cox proportional hazard models, with repeat analysis after reweighting of data via inverse probability of treatment weighting. RESULTS:= .004]). CONCLUSION/CONCLUSIONS:Surgical treatment with neoadjuvant or adjuvant treatment for stage T4b sinonasal SCC was associated with promising survival outcomes, suggesting a role for incorporating surgery in treatment of select T4b SCC, particularly when removal of all macroscopic disease is feasible.

Introduction: Thyroidectomy is commonly performed in otolaryngology. Complications such as recurrent laryngeal nerve (RLN) injury and severe hypocalcemia have reported incidences in national studies as high as 3% and 8%, respectively. Narcotic pain medications are commonly used for postoperative pain management. Here, we present the long-term results of a thyroidectomy quality and safety improvement program, with an emphasis on reducing narcotic use.
Method(s): All surgeons who perform thyroidectomy established standards for antibiotic administration, postoperative calcium management, and narcotics use. The program was established in 2018 and data on adverse events, length of stay, antibiotic and narcotic use were recorded prospectively from June 2018 to January 2021. Data trends were analyzed throughout the course of the study.
Result(s): During the study period, 542 thyroidectomies were performed by 14 surgeons. The average length of stay was less than 24 hours. Five (0.9%) adverse events were recorded: 1 (0.2%) temporary RLN dysfunction, 3 (0.6%) hematomas, 1 (0.2%) surgical site infection, and 1 (0.2%) temporary hypocalcemia. The average number of narcotics prescribed declined from 18 doses (95%CI: 16.8-18.5) in 2019 to 9 in 2020 (95%CI: 8.5-9.6) (p<0.0001), without an increase in need for refills. No instances of permanent hypocalcemia or permanent RLN injury were identified.
Conclusion(s): By implementing a thyroidectomy quality improvement program, we achieved extremely low rates of adverse events and significantly reduced the use of narcotics without adverse effects. These data can inform practitioners and the public about expected outcomes of thyroid surgery, and establish benchmarks for quality and safety.

Background: Surgical resection is required for curative treatment of patients with extra-hepatic cholangiocarcinoma (EH-CCA). The objective of this study was to determine if the distance of surgical margin was associated with outcome.
Method(s): Patients who underwent curative-intent resection for EH-CCA between 2000 and 2015 at 10 hepatobiliary centers across the U.S. were evaluated using prospectively collected data. Cox proportional hazard model was utilized to evaluate the influence of the extent of the margin on outcome.
Result(s): 538 patients with EH-CCA who underwent curative-intent resection were included: 383 (71%) undergoing R0 resection, 153 (28%) undergoing R1 resection, and 2 with R2 resection. A negative surgical margin (R0) was associated with improved recurrence-free (RFS) and overall survival (OS) (RFS: 10.5% vs. 3.6% (R1) and OS: 25.8% vs. 9.3% (R1). Subsequently, further analysis on 161 patients with complete data on distance of resection margin, all undergoing R0 resection, was performed to assess the impact of extent of margin on outcome. On multi-variable analysis, the resection margin distance, analyzed as a continuous variable, was not associated with either improved RFS (RR 1.00, 95% CI 0.96-1.05; p 0.71) or OS (RR 0.99, 95% CI 0.96-1.01; p 0.49). Increasing age, increased tumor size, and LN metastasis were identified as independent predictors of OS; while RFS were mainly dependent on tumor size and LN metastasis (Table).
Conclusion(s): Achieving R0 resection is acceptable for EH-CCA tumors, and obtaining additional margin does not confer a benefit on overall survival. Increasing age, tumor size, and LN metastasis are independent predictors of RFS and OS, but increased margin width is not associated with improvement in either.
