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.
