title: [Radicality principles in operations on malignant thyroid tumors].
abstract: Different concepts are required by different tumors: anaplastic carcinomas rarely are accessible to curative surgery, but tumor reduction gives sense in combined concepts. In follicular carcinomas general ("near"-) total thyroidectomy + radioiodine + hormonal suppressive therapy is recommended, with respect to the high incidence of distant metastases even in low 1 degree Tu-stages. Papillary carcinomas allow a stage related procedure with exceptions from total thyroidectomy: no reintervention for "occult" carcinomas and-in patients under 40 years of age-hemithyroidectomy for intrathyroid tumors without regional metastases. In C-Cell-carcinomas total thyroidectomy has to be accompanied by lymph-node dissections of various extent, depending on familiary or sporadic type and tumor-stage.
