[Papillary cancer of the thyroid: biological behaviour and therapeutic planning (author's transl)].

Out of about 600 thyroid tumors treated from 1956 to 1976, a series of 216 papillary cancers were selected at an hystological reevaluation. The correlation between survival rate and clinical features as well as extent of the primary tumor and presence of regional and distant metastases was investigated. An improvement in results may be expected by more extensive surgery on the thyroid, adequate post-operative X-ray and 131I radiation therapy, associated with suppression of TSH production in case of endocrine-dependent tumors.
