Comparison of Voice Results at 5 Years of Treatment of Glottic Squamous Cell Carcinoma T1 by Surgery Versus Radiotherapy

Patients with early-stage squamous cell carcinomas of the vocal cord can be treated in an equivalent way in terms of carcinology by surgery or radiotherapy. The study will be to analyse the vocal outcome at 5 years of these two types of management in order to define whether one is superior to the other on this criterion of voice quality after treatment.

Precision Medicine: MRI-Guided Stereotactic Ablative Radiotherapy (MRI-SABR) for Early-Stage Glottic Laryngeal Cancer

This randomized phase III trial will compare the outcomes of three treatment modalities for early-stage glottic laryngeal cancer (T1-T2N0): transoral CO₂ laser microsurgery (TLM), volumetric modulated arc therapy (VMAT), and MRI-guided stereotactic ablative radiotherapy (MRI-SABR). The primary endpoint is local control (LC). Secondary endpoints include laryngectomy-free survival (LFS), progression-free survival (PFS). overall survival (OS), functional voice, swallowing and breathing outcomes, treatment-related complications, and the evaluation of radiomic and dosiomic biomarkers. Patients will be randomized in a 1:1:1 ratio. Total planned enrollment is 105.

Clinical Treatments in Specialized Diseases of Laryngeal Carcinoma (LC) and Hypopharyngeal Carcinoma (HPC)

For early stage laryngeal carcinoma and hypohparyngeal carcinoma (T1 and T2), transoral laser microsurgery, open partial laryngectomy, radiotherapy, and transoral robotic surgery were performed according to NCCN guidelines (2020). For advanced stage laryngeal carcinoma and hypohparyngeal carcinoma (T3 and T4), surgical treatment ± postoperative adjuvant therapy, chemoradiotherapy, neoadjuvant therapy + radiotherapy/chemoradiotherapy, or neoadjuvant therapy + surgery + radiotherapy or chemoradiotherapy performed according to NCCN guidelines (2020). This study plan to analyze the clinical ouctomes of different treatment for the same T stage disease. The overall survival rate, disease specific survival, disease free survival, local control, regional control, and laryngeal function preservation rate were analyzed in this study.

Clinical Study of Curcumin in Preventing Postoperative Adhesion of Bilateral Vocal Cords

To provide a novel therapy idea and method to solve the clinical problem of postoperative adhesion of bilateral vocal cords, patients enrolled in this study will be applied with curcumin on both wound sites of bilateral vocal cords after the surgery on the bilateral vocal cord endoscopically.
