Abstrakt: The natural history of chronic radiation esophagitis occuring in previously normal esophagus is still unknown. We describe here the long-term outcome of chronic esophagitis arising after neck irradiation for oropharynx and larynx carcinomas in 13 consecutive adult patients. The first clinical signs of radiation esophagitis were dysphagia or impossibility of oral intake, which appeared within 26 months (range 2–120 months) after the end of radiation for pyriform fossae carcinoma (N=5), tonsil carcinomaN=2), larynx carcinoma (N=2), pharynx carcinoma (N=2), base of the tongue (N=1), and thyroid carcinomas (N=1). During upper endoscopy, an esophageal stenosis was found in 11 cases and was associated with ulceration in three cases. An isolated esophageal ulceration was present in only two cases. Chronic radiation esophagitis diagnosis was confirmed by histology and durgery in seven cases. In the last six cases, diagnosis was supported by the absence of first cancer relapses within a median follow-up of two years (16 months to nine years) and by endoscopic findings. Seven patients received parenteral or enteral nutrition. Ten patients were treated by peroral dilatation. These treatments allowed nearly normal oral diet in 11/13 patient. Only one patient was lost of follow-up after 20 months. Four patients died from chronic radiation esophagitis. One of these patients died from massive hemorrhage after peroral dilatation. Four patients died of a second carcinoma with no first cancer recurrence. Four patients were alive after dix months to nine years of follow-up. Moderate dysphagia was still present, allowing nearly normal oral feeding. In conclusion, chronic radiation esophagitis is a severe disease with an underestimated frequency. In our study, peroral dilatations appeared to be necessary and were not associated with an increased morbidity.
