Background: The purpose of simultaneous chemoradiotherapy is to increase local-regional control and to decrease the incidence of distant metastases. Regimens containing cisplatin/5-FU chemotherapy are widely accepted as standard treatment in advanced head and neck cancer. Most studies reported promising response and survival data, but also severe mucosal toxicity. In recent years the newly developed drug Taxol demonstrated interesting activity in head and neck cancer as a single agent and as well in combination drug regimens. In the present outpatient phase-II trial we investigated the combination of Taxol/carboplatin with 40 Gy radiotherapy in a neoadjuvant setting of operable Stage-III/IV squamous cell carcinoma of the oral cavity and oropharynx.
Patients And Methods: Twelve patients were enrolled in this ongoing trial with a projected number of 30 patients and received 5 cycles of weekly Taxol (40 mg/m2) and carboplatin (AUC 1.5) with conventional radiotherapy (40 Gy). Within 3 to 4 weeks after chemoradiotherapy resection of the primary tumor and the regional neck nodes was performed.
Results: So far 12 patients were evaluable for toxicity and response. Complete response was noted in 8/12 patients (CR 66%). In 6/10 patients (60%) complete pathologic response was documented in the resection specimens.
Conclusion: Our preliminary results demonstrated excellent clinical and pathological response rates of concurrent Taxol/carboplatin and radiotherapy as preoperative treatment modality in advanced oral and oropharyngeal cancer.

Background: Radioactive iodine (RAI) is a common treatment for various thyroid diseases. Previous studies have suggested susceptibility of parathyroid glands to the mutagenic effect of RAI and the development of primary hyperparathyroidism (PHPT). We tested the possible link between prior RAI treatment, disease presentation, and treatment outcomes.

T-helper 17 (Th17) cells significantly influence the onset and advancement of malignancies. This study endeavor focused on delineating molecular classifications and developing a prognostic signature grounded in Th17 cell differentiation-related genes (TCDRGs) using machine learning algorithms in head and neck squamous cell carcinoma (HNSCC). A consensus clustering approach was applied to The Cancer Genome Atlas-HNSCC cohort based on TCDRGs, followed by an examination of differential gene expression using the limma package.

Purpose: Financial toxicity (FT) has been linked to higher symptom burden and poorer clinical outcomes for patients with cancer. Despite the availability of validated tools to measure FT, a simple screen remains an unmet need. We evaluated item 12 ("My illness has been a financial hardship to my family and me") of the COmprehensive Score for Financial Toxicity (COST) measure as a single-item FT screening measure.

Department of Otolaryngology and Head and Neck Surgery, Graduate School of Medicine, The University of Tokyo, Bunkyo-ku, Tokyo, Japan.
Objective: This multicenter, randomized, double-blind, placebo-controlled, crossover trial aimed to evaluate whether prolonged noisy galvanic vestibular stimulation improves body balance in patients with vestibulopathy.
Materials And Methods: This trial was registered in the Japan Pharmaceutical Information Center Clinical Trials Information registry (jRCT1080224083). Subjects were 20- to 85-year-old patients who had been unsteady for more than one year and whose symptoms had persisted despite more than six months of rehabilitation.
Real sounds influence postural stability in people with vestibular loss but not in healthy controls.

Department of Otolaryngology-Head and Neck Surgery, Icahn School of Medicine at Mount Sinai, New York, NY, United States of America.
Objective: What we hear may influence postural control, particularly in people with vestibular hypofunction. Would hearing a moving subway destabilize people similarly to seeing the train move? We investigated how people with unilateral vestibular hypofunction and healthy controls incorporated broadband and real-recorded sounds with visual load for balance in an immersive contextual scene.
Design: Participants stood on foam placed on a force-platform, wore the HTC Vive headset, and observed an immersive subway environment.
