[Prognosis of follicular thyroid cancer in the Tyrolean endemic goiter area].

89 follicular thyroid cancers (from 1952 to 1975) with detailed histology, complete clinical data and follow-up were analysed by several variables of which some prognostic importance could be expected. The observed survival times range from 0.08 to 27.75 years. Observed cumulative and expected survival rates were calculated and evaluated statistically. Evaluation of individual prognosis naturally demands a combination of histological, macropathological and clinical data: extent of primary tumor, capsular penetration and vascular infiltration, lymphnode involvement and distant metastases proved to be important parameters. The classification in intra-and extrathyroid carcinoma is to be preferred to the T-classification of the UICC, because it is simple and of great prognostic value.
