Prognostic Utility of Tumor Stage versus American Thyroid Association Risk Class in Thyroid Cancer

alexandrossfakianakis shared this article with you from Inoreader Prognostic Utility of Tumor Stage versus American Thyroid Association Risk Class in Thyroid Cancer via The Laryngoscope The prognostic strengths of American Joint Committee on Cancer (AJCC) staging and American Thyroid Association (ATA) risk classification in well-differentiated thyroid cancer were evaluated. AJCC staging served as a more prognostic model for patient survival compared to ATA risk classification. The greater predictive strength of AJCC staging became less pronounced when multiple additional demographic and clinical factors were considered. Objective To evaluate the prognostic strengths of American Joint Committee on Cancer (AJCC) staging and American Thyroid Association (ATA) risk classification in well-differentiated thyroid cancer (DTC), and their implications in guiding medical decision-making and epidemiological study designs. Methods The 2004–2017 National Cancer Database was queried for DTC patients. Cox proportional hazards (CPH) and Kaplan–Meier analyses modeled patient mortality and overall survival, respectively. Each CPH model was evaluated by its concordance index, measure of explained randomness (MER), Akaike information criterion (AIC), and area under receiver operating characteristic curve (AUC). Results Overall, 134,226 patients were analyzed, with an average age of 48.1 ± 15.1 years (76.9% female). Univariate CPH models using AJCC staging demonstrated higher concordance indices, MERs, and AUCs than those using ATA risk classification (all p < 0.001). Multivariable CPH models using AJCC staging demonstrated higher concordance indices (p = 0.049), MERs (p = 0.046), and AUCs (p = 0.002) than those using ATA risk classification. The AICs of multivariable AJCC staging and ATA risk models were 7.564 × 104 and 7.603 × 104, respectively. AJCC stage I tumors were associated with greater overall survival than those classified as ATA low risk, whereas AJCC stages II-III and stage IV tumors demonstrated worse survival than ATA intermediate- and high-risk tumors, respectively (all p < 0.001). Conclusion AJCC staging may be a more predictive system for patient survival than ATA risk. The prognostic utility of these two systems converges when additional demographic and clinical factors are considered. AJCC staging was found to classify patients across a wider range of survival patterns than the ATA risk stratification system. Level of Evidence 4 Laryngoscope, 2022 View on Web

Changes in Cough Airflow and Acoustics After Injection Laryngoplasty

alexandrossfakianakis shared this article with you from Inoreader Changes in Cough Airflow and Acoustics After Injection Laryngoplasty via The Laryngoscope We explored the following hypotheses in a cohort of patients undergoing injection laryngoplasty: (1) glottic insufficiency affects voluntary cough airflow dynamics and restoring glottic competence may improve parameters of cough strength, (2) cough strength can be inferred from cough acoustic signal, and (3) glottic competence changes cough sounds and correlates with spectrogram morphology. Our study thus indicates that injection laryngoplasty may help avert aspiration in patients with glottic insufficiency by improving cough effectiveness and that improved cough airflow measures may be tracked with cough sounds. Objective/Hypothesis We explored the following hypotheses in a cohort of patients undergoing injection laryngoplasty: (1) glottic insufficiency affects voluntary cough airflow dynamics and restoring glottic competence may improve parameters of cough strength, (2) cough strength can be inferred from cough acoustic signal, and (3) glottic competence changes cough sounds and correlates with spectrogram morphology. Study Type/Design Prospective interventional study. Methods Subjects with glottic insufficiency secondary to unilateral vocal fold paresis, paralysis, or atrophy, and scheduled for injection laryngoplasty completed an instrumental assessment of voluntary cough airflow using a pneumotachometer and a protocolized voluntary cough sound recording. A Wilcoxon signed-rank test was used to compare the differences between pre- and post-injection laryngoplasty in airflow and acoustic measures. A Spearman rank-order correlation was used to evaluate the association between airflow and acoustic cough measures. Results Twenty-five patients (13F:12M, mean age 68.8) completed voluntary cough airflow measurements and 22 completed cough sound recordings. Following injection laryngoplasty, patients had a statistically significant decreased peak expiratory flow rise time (PEFRT) (mean change: −0.03 s, SD: 0.06, p = 0.04) and increased cough volume acceleration (mean change: 13.1 L/s2, SD: 33.9, p = 0.03), suggesting improved cough effectiveness. Correlation of cough acoustic measures with airflow measures showed a weak relationship between PEFRT and acoustic energy (coefficient: −0.31, p = 0.04) and peak power density (coefficient: −0.35, p = 0.02). Conclusions Our study thus indicates that injection laryngoplasty may help avert aspiration in patients with glottic insufficiency by improving cough effectiveness and that improved cough airflow measures may be tracked with cough sounds.

De‐Novo Depression, Prophylactic Antidepressant, and Survival in Patients With Head and Neck Cancer

alexandrossfakianakis shared this article with you from Inoreader De‐Novo Depression, Prophylactic Antidepressant, and Survival in Patients With Head and Neck Cancer via The Laryngoscope Kaplan-Meier Survival Curve Modeled for Time to Death from Enrollment stratified by Primary Outcome of Moderate or Greater Depression. Objective To study the association between the development of moderate or greater depression during curative-intent therapy and overall survival (OS) in patients with stages II-IV head and neck cancer (HNC). Methods In this secondary analysis of a randomized double-blind placebo-controlled trial, of 148 eligible participants diagnosed with stages II-IV HNC but without baseline depression, 125 were evaluable and were randomly allocated to prophylactic escitalopram oxalate (n = 60) or placebo (n = 65). Participants were followed for development of moderate or greater depression, using Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR, range 0–27, score ≥11 indicated moderate or greater depression), and were stratified by demographics; cancer site and stage; and primary treatment modality (surgery with or without radiotherapy vs. radiotherapy with or without chemotherapy). Single variable and multivariable Cox proportional-hazard models were used to evaluate differences in OS. Results Clinically significant depression developed in 22 of 125 patients (17.6%) during HNC treatment. The mean follow-up was 5.0 years (SD 2.4). OS was similar for patient groups, when stratified by development of moderate or greater depression (HR 0.54 [CI, 0.21–1.43]) or use of prophylactic antidepressant (HR 0.64 [CI, 0.34–1.21]). Conclusion There was no significant association between OS and development of moderate or greater depression in patients being treated for stages II-IV HNC, or between OS and use of prophylactic antidepressant escitalopram. Prophylactic antidepressant may be considered in patients with HNC for prevention of clinically significant depression and may offer improved quality of life outcomes.
