Adjuvant Radiotherapy in Moderately Advanced (T3) Oral Cavity Cancers.

OBJECTIVE: To investigate the impact of adjuvant radiotherapy in isolated locally advanced oral cavity cancers (pT3N0M0) without adverse features. METHODS: We selected all patients from the National Cancer Database (2004-2019) who underwent surgical treatment where the final pathology was T3N0M0 with negative margins. Demographics, details of treatment, and outcomes were abstracted. The impact of radiotherapy on survival was assessed with univariable, multivariable, and propensity score-matched analyses. RESULTS: We identified 571 patients in our survival cohort. Most were male (348, 60.9%), and median age was 65. Less than one-third (176, 30.8%) received adjuvant radiotherapy. The median length of follow-up was 29 months. Overall, adjuvant radiotherapy was associated with improved survival (87.2% vs. 77.7%, at 2 years, p < 0.01). On multivariable analysis controlling for age and comorbidities, this survival difference persisted (HR: 0.62, 95% CI: 0.43-0.90, p = 0.01). In a propensity score-matched population of 278 patients matched on age and comorbidities, adjuvant radiotherapy was still associated with longer survival (87.4% vs. 78.5%, p = 0.014). CONCLUSION: In our study, adjuvant radiotherapy was associated with improved survival in completely excised locally advanced oral cavity tumors (T3N0M0). However, a significant proportion of patients do not receive adjuvant radiotherapy. These findings highlight the need for continued efforts to promote guideline-recommended care.

Management of Enlarging Tracheoesophageal Fistula with Voice Prosthesis in Laryngectomized Patients.

Management of Enlarging tracheoesophageal fistula (TEF) with Voice Prosthesis in Laryngectomized Head and Neck Cancer Patients. OBJECTIVES: An enlarging TEF following voice prosthesis placement impacts patient quality of life, risks airway compromise, and can lead to aspiration pneumonia. Pharyngoesophageal strictures have previously been reported to be associated with TEF enlargement and leakage. We describe a series of patients with enlarging TEFs after Tracheoesophageal puncture (TEP) for voice prosthesis who required pharyngoesophageal reconstruction. METHODS: Retrospective case series of laryngectomized H&N cancer patients with primary or secondary TEP who underwent surgical management for enlarging TEF site between 6/2016-11/2022. RESULTS: Eight patients were included. The mean age was 62.8 years old. Seven patients had a history of hypothyroidism. Of seven with prior H&N radiation history, two had both historical and adjuvant radiation. Two of the eight TEPs were placed secondarily. Mean time from TEP to enlarging TEF diagnosis was 891.3 days. Radial forearm-free flaps were used in five patients. Six had stenosis proximal to the TEF whereas one had distal stenosis and one had no evidence of stenosis. Mean length of stay was 12.3 days. Mean follow-up was 400.4 days. Two required a second free flap for persistent fistula. CONCLUSION: Surgical reconstruction of enlarging TEFs due to TEP/VP placement is effective in combination with addressing underlying pharyngeal/esophageal stenosis contributing to TEF enlargement and leakage. Radial forearm-free flaps have the additional benefit of a long vascular pedicle to access more distant and less-irradiated recipient vessels. Many fistulae are resolved after the first flap reconstruction, but some may require subsequent reconstruction in case of failure. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:198-206, 2024.

The RVU Compensation Model and Head and Neck Surgical Education.

BACKGROUND: The present study aims to quantify the opportunity cost of training residents and fellows for head and neck surgery. METHODS: A 2005-2015 review of ablative head and neck surgical procedures was performed using the National Surgical Quality Improvement Program (NSQIP). Work relative value units (wRVU) generated per hour were compared among procedures performed by attendings alone, attendings with residents, and attendings with fellows. RESULTS: Among 34,078 ablative procedures, the rate of wRVU generation per hour was greatest for attendings alone (10.3), followed by attendings with residents (8.9) and attendings with fellows (7.0, p < 0.001). Resident and fellow involvement was associated with opportunity costs of $60.44 per hour (95% CI: $50.21-$70.66/h) and $78.98 per hour ($63.10-$94.87/h, 95% CI), respectively. CONCLUSION: wRVU-based physician reimbursement does not consider or adjust for the extra effort involved in training future head and neck surgeons.

Role of transoral robotic surgery in surgical treatment of early-stage supraglottic larynx carcinoma.

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.

Adoption of adjuvant chemotherapy in high-risk salivary gland malignancies.

BACKGROUND: The present study characterizes national trends in the utilization of adjuvant chemotherapy to treat salivary gland malignancies. METHODS: The National Cancer Database was queried for salivary gland malignancies treated by surgery with radiation in 2004-2019. Proportions of patients receiving adjuvant chemotherapy over the study period were analyzed by linear regression. The impact of chemotherapy on overall survival was assessed using Kaplan-Meier and Cox proportional hazards analyses. RESULTS: Among 15 965 patients meeting inclusion criteria, 2355 (14.8%) received adjuvant chemotherapy. Chemotherapy utilization significantly increased from 4.9% to 16.5% over the study period (p < 0.001). No survival benefit was observed with adjuvant chemotherapy on propensity score-matched Kaplan-Meier analysis (HR: 0.98; 95% CI: 0.86-1.11; p = 0.72) or multivariable Cox regression (HR: 0.92; 95% CI: 0.78-1.09; p = 0.34). CONCLUSIONS: Adjuvant chemotherapy has been increasingly utilized to treat salivary gland malignancies in recent years. Our findings highlight the importance of obtaining high-quality prospective data regarding the benefit of chemotherapy.

American Thyroid Association Guidelines and National Trends in Management of Papillary Thyroid Carcinoma.

Importance: Over time, the American Thyroid Association (ATA) guidelines have increasingly promoted more limited treatments for well-differentiated thyroid cancers. Objective: To determine whether the 2009 and 2015 ATA guidelines were associated with changes in the management of low-risk papillary thyroid carcinomas on a national scale. Design, Setting, and Participants: This historical cohort study used the National Cancer Database. All papillary thyroid carcinomas diagnosed from 2004 to 2019 in the National Cancer Database were selected. Patients with tumors of greater than 4 cm, metastases, or clinical evidence of nodal disease were excluded. Data were analyzed from August 1, 2021, to September 1, 2022. Main Outcomes and Measures: The primary aim was to tabulate changes in the rates of thyroid lobectomy (TL), total thyroidectomy (TT), and TT plus radioactive iodine (RAI) therapy after the 2009 and 2015 ATA guidelines. The secondary aim was to determine in which settings (eg, academic vs community) the practice patterns changed the most. Results: A total of 194 254 patients (155 796 [80.2%] female patients; median [range] age at diagnosis, 51 [18-90] years) who underwent treatment during the study period were identified. Among patients who underwent surgery, rates of TL decreased from 15.1% to 13.7% after the 2009 guidelines but subsequently increased to 22.9% after the 2015 changes. Among patients undergoing TT, rates of adjuvant RAI decreased from 48.7% to 37.1% after 2009 and to 19.3% after the 2015 guidelines. Trends were similar for subgroups based on sex and race and ethnicity. However, academic institutions saw larger increases in TL rates (14.9% to 25.7%) than community hospitals (16.3% to 19.5%). Additionally, greater increases in TL rates were observed for tumors 1 to 2 cm (6.8% to 18.9%) and 2 to 4 cm (6.6% to 16.0%) than tumors less than 1 cm (22.8% to 29.2%). Conclusions and Relevance: In this cohort study among patients with papillary thyroid carcinomas up to 4 cm, ATA guideline changes corresponded with increased TL and reduced adjuvant RAI. These changes were primarily seen in academic institutions, suggesting an opportunity to expand guideline-based care in the community setting.

Comparison of tracheal resection outcomes at a university hospital vs county hospital setting.

OBJECTIVES: To evaluate the role of hospital setting on outcomes in open airway surgery by comparing patients who underwent surgery (cricotracheal resection [CTR] or tracheal resection [TR]) at a publicly funded county hospital vs a private university hospital. METHODS: Retrospective chart review of patients undergoing CTR or TR at two institutions; a private university hospital and a publicly funded county hospital from September 2014 to September 2019. Length of intensive care unit (ICU) stay, total time to discharge, minor and major complications were the primary endpoints. Significance was defined as a P-value less than .05. RESULTS: There were a total of 43 patients (17 county, 26 university) who had CTR or TR during the study period. Length of stay outcomes was reported as mean length of stay ± SD. There was a significant difference in ICU stay at the county hospital (7.17 (±5.36 days) compared to the university hospital (2.52 ± 1.85 days, P < .003) and a nearly significant total length of stay difference at the county hospital (12.4 ± 9.06 days) compared to the university hospital (7.84 ± 4 days, P < .072) There was overall a low incidence of complications but slightly more in the county compared to the university population. CONCLUSION: Patients who underwent open airway surgery at the county hospital were more likely to have a longer ICU stay and slight increase in complications despite having a lower ASA (American Society of Anesthesiologists) classification and younger age. These outcomes are multifactorial and may be related to poorer access to primary care preoperatively leading to delay in diagnosis and treatment, poorly controlled or undiagnosed medical comorbidities, and differences in hospital resources.
