AbstractCervical esophageal carcinoma (CEC) is rare, accounting for 2-10% of esophageal cancers and is mostly squamous cell carcinoma. Because of the anatomical proximity of CEC to larynx, surgical treatment would involve pharyngo-laryngo-esophagectomy (PLE) with inherent high mortality and morbidity. Laryngeal preservation is an important consideration, and definitive chemoradiotherapy is the recommended treatment. Treatment strategy of CEC can be more akin to treatment for head and neck cancers than to thoracic esophageal cancers. Since the exact location, extent of primary and nodal metastasis varies between patients, radiotherapy treatment needs to be individualized. The optimal radiation dose for CEC is uncertain, but retrospective data suggests that higher radiation dose of at least 60 Gy is associated with better local control and survival. Advanced radiotherapy technique, like intensity modulated radiotherapy, is usually required to achieve high dose to tumor while protecting normal tissues from excessive radiation.
