[Intracavitary irradiation of esophageal cancer].
Intracavitary irradiation (ICI) of esophageal cancer is a technique where the radioactive source is placed in the lumen of the esophagus thereby delivering a high local radiation dose to the tumor. ICI is used as single modality therapy for palliation of dysphagia or as a supplement to external irradiation. Dysphagia is hereby relieved in more than 90% of the patients and it appears that survival is improved. The side effects are dose dependent and consist of esophagitis, esophageal ulceration and benign stricture. Fistulae do not seem to occur with increased frequency after ICI, but an existing fistula is claimed to be a contraindication to ICI. The mortality connected with ICI is considerably lower than with tubulation or laser extirpation. It is concluded that ICI is a promising treatment in esophageal cancer both as palliative and curative treatment in combination with other treatment modalities.
