Impact of Socioeconomic Demographics and Race on Laryngotracheal Stenosis Etiology and Outcomes.

OBJECTIVE: Certain sociodemographic variables are known to result in health care disparities. This study investigates potential differences in outcomes for patients with laryngotracheal stenosis (LTS) based on racial backgrounds and socioeconomic variables including insurance status and English language-Proficiency. METHODS: Patients with LTS from 2016 to 2021were identified by relevant ICD codes. Variables including race, age, gender, language preference and insurance status were collected from medical records. Risk factors for LTS including COPD, smoking history, diabetes, GERD, and BMI were obtained. Etiology of LTS was categorized as autoimmune, traumatic, iatrogenic, or idiopathic. Need for temporary tracheostomy and tracheostomy dependence were determined at last follow-up visit. RESULTS: 129 patients were included for review. 70% of Black patients had iatrogenic LTS, whereas 65% of the White patient cohort had autoimmune or idiopathic LTS. Black patients were more strongly associated with temporary tracheostomy and tracheostomy dependence compared to White patients. Public health insurance and co-morbid GERD were associated with tracheostomy dependence for White patients only. CONCLUSION: This study identified a disproportionate representation of Black patients in the iatrogenic etiology of LTS. Although controlling for risk factors of LTS, this cohort had an increased need for temporary tracheostomy and tracheostomy dependence compared to White and Latinx cohorts. This finding merits further study. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:908-913, 2023.

Choice of imaging modality for pre-treatment staging of head and neck cancer impacts TNM staging.

PURPOSE: The purpose of this retrospective cohort study was to determine whether there is a difference in the sensitivity of chest computed tomography (CT) versus 18F-fluorodeoxyglucose positron emission tomography with low-dose nonenhanced CT (18F-FDG PET/CT or PET/CT) in the detection of distant metastases in head and neck cancer, within a tertiary care setting. MATERIALS AND METHODS: Patients with head and neck cancer, and known distant metastases, who underwent both 18F-FDG PET/CT with integrated low-dose nonenhanced CT and diagnostic chest CT prior to initiation of therapy from 2008 to 2017 were included. Two head and neck radiologists, blinded to all patient information and to each other's readings, reviewed the PET/CT or CT chest images for each patient and identified whether distant metastases were present. No radiologist read both modalities for a single patient. Concordance between imaging modalities was quantitatively analyzed using McNemar's test. RESULTS: 27 patients were included. McNemar's mid p-value analysis showed no significant difference in the detection of distant metastases (p = .6875). However, PET/CT detected distant metastases in three patients that chest CT did not, while chest CT identified distant metastatic disease in two patients that were negative on PET/CT. CONCLUSIONS: While this study did not identify a statistically significant difference in sensitivity, five patients had distant metastases identified on only one of the two modalities. Use of a single modality would have resulted in inaccurate staging in 7-11% of patients in our study. The use of both modalities offers the greatest accuracy when providing stage-adapted oncologic treatment.
