[Adenocarcinoma of the distal esophagus treated with external and intracavitary radiotherapy. Description of a clinical case and review of the literature].

The prognosis of esophageal adenocarcinoma is extremely poor. Despite recent improvements in diagnostic and therapeutic techniques, the 5-years survival rate remains below 10%. Management is primarily surgical or radiotherapeutical, although pre- or postoperative radiation or chemotherapy are often employed. Chemotherapy alone, however, has not demonstrated great therapeutic efficacy in the management of this neoplasm. As most patients with cancer of the lower esophagus have an advanced stage of the disease and a very poor prognosis, the main aim of treatment should be to improve the quality of life. Intracavitary radiation (high dose rate) is a well recognised method of treatment alone or in combination with external radiotherapy. Its simplicity, the convenience of short treatment time and radiation safety provided by the remote after loading system make this the ideal palliative treatment in esophageal cancer. Endoscopic techniques, like dilation and endoprosthesis placement, laser therapy or BI-CAP probe, provide good palliation for dysphagia, with a low morbidity rate. The paper describes a case of lower esophageal adenocarcinoma treated with combined external and intracavitary radiation and endoscopic palliative techniques. Good control of the disease was achieved and the patient is alive 26 months after treatment with a good quality of life.
