[Treatment of a thyroid neoplasm infiltrating the respiratory-digestive tracts].

From 1992 to 1999, 58 thyroid gland operations (41 female and 17 male) were performed in ENT Department of the District Hospital in Rzeszów. In 14 (21.4%) cases (9 female and 5 male) thyroid surgery was done for malignant disorders: papillary carcinoma in 11 (79%) patients, follicular carcinoma in 2 patients and medullary carcinoma in 1 patient. There were neck metastases in 9/14 (64.4%) patients. In 3 cases with papillary carcinoma (all with neck metastases) aerodigestive tract was invaded. One patient had neoplasmatic invasion of the larynx and trachea, one patient had invasion of larynx et pharynx and in one patient tumour invaded the esophageal wall. In those patients radical surgery was done: total thyroidectomy with total laryngectomy and radical neck dissection (2 patients) and subtotal thyroidectomy with conservative neck dissection (1 patient). External beam irradiation and radioactive iodine 131 treatment followed surgery. Two patients are still alive 6 years after the treatment free of disease, and 1 patient died of unrelated causes 3 months after the surgery. Symptoms, diagnostic evaluation and treatment of thyroid papillary carcinoma invading the aerodigestive tract are detailed in paper.
