Description: For early stage laryngeal carcinoma and hypohparyngeal carcinoma (T1 and T2), transoral laser microsurgery (CO2 laser resection), open partial laryngectomy (vertical partial laryngectomy, cricohyoidoepiglottopexy, cricohyoidopexy, horizontal partial laryngectomy), partial hypopharyngectomy, radiotherapy, and transoral robotic surgery were performed for patients with proper indications (NCCN 2020).~For advanced stage laryngeal carcinoma and hypohparyngeal carcinoma (T3 and T4), surgical treatment ± postoperative adjuvant therapy, concurrent chemoradiotherapy, neoadjuvant therapy + radiotherapy/chemoradiotherapy, or neoadjuvant therapy + surgery + radiotherapy or chemoradiotherapy were performed for patients with proper indications (NCCN 2020).
