RESUMO
Palliative treatment by intracavitary irradiation alone has been used in 15 patients with advanced carcinoma of the esophagus. Most of them had already failed other palliative modalities including external irradiation, chemoradiotherapy, laserotherapy and dilatation. Intracavitary irradiation was carried out with a microSelectron HDR afterloading device and usually 22.5 Gy was given in three fractions repeated weekly. Up to three month after treatment, complete endoscopic regression was seen in 1 patient, partial endoscopic regression in 8 patients, no response in one and progressive disease in 5 patients. The median survival time is 6.2 months. There were not severe complications. We conclude that high dose rate intracavitary irradiation is a useful palliative modality in patients with advanced or recurrent esophageal cancer.

Two sisters are reported treated at various times for thyroid medullary carcinoma. In one of them, treated later, right adrenal tumour coexisted suggesting a classical picture of the syndrome of multiglandular endocrine adenomatosis type 2a. Histological examination of the adrenal tumour showed presence of metastasis of medullary thyroid carcinoma, that is atypical pattern of this neoplasm. In the light of these the authors stress the necessity of comprehensive diagnosis of thyroid tumours with particular stress laid on histological preoperative diagnosis. Indications are discussed to thyroid reoperation in patients in whom medullary thyroid carcinoma was diagnosed only in the resected goitre.
