[The significance of the AMES and the NTM systems to determine the prognosis in patients with differentiated cancer of the thyroid]. / La importancia de los sistemas AMES y NTM para determinar el pronóstico en los pacientes con cáncer diferenciado del tiroides.

The author considers that the AMES and TNM systems are reliable in determining the prognosis in patients with well differentiated thyroid carcinoma. In low risk patients with tumors less than 2 cm in diameter, total lobectomy and hormonal suppression are sufficient therapy. In other patients, total or subtotal thyroidectomy are advisable to facilitate further control and therapy. Total or subtotal thyroidectomy should always be done in high risk patients. Metastases to the regional lymph nodes are not an important risk factor, but they should always be excised. Radioactive iodine therapy is not useful for low risk patients.
