若年者（21歳）頸胸境界部食道癌の1例

A Case of Cervicothoracic Esophageal Cancer

　はじめに

　食道癌は，特に高齢者に多く発症する癌腫であり，若年発症例はきわめて稀であり，20歳台の症例報告は皆無に近い^1）。また，食道癌のなかでも頸胸境界部食道癌の頻度は比較的低い。今回，われわれは21歳男性に発生した頸胸境界部食道癌を経験した。ネオアジュバント療法として化学療法と放射線療法の併用の後に喉頭を温存した手術を行ったので，若干の文献的考察を加えて症例を報告する。

A 21-year-old male patient with advanced cer-vicothoracic esophageal cancer presented with the chief complaint of an abnormal sensation in the pharyngolaryngeal region. Roentgenological exami-nation revealed a stenotic region in the cervicothor-acic region of the esophagus (Iu-Ce). The his-tological diagnosis of endoscopically biopsied specimen was poorly differentiated squamous cell carcinoma. To maintain the patient's quality of life, total esophagectomy without laryngectomy was performed after preoperative neo-adjuvant radia-tion and chemotherapy.

Very few cases of esophageal cancer in patients under the age of 29 have been reported in Japan. To our knowledge, the present case may be the young-est of cervicothoracic esophageal cancer in this country. Early esophagography is very important in the examination of even young patients with com-plaints of an abnormal sensation in the pharyngolar-yngeal region.
