A statistical and pathological correlative study of 434 thyroid carcinomas observed between 1967 and 1975.

The authors studied 434 cases of thyroid carcinoma. The sex distribution showed a strong predominance of women (67%). The highest percentage (47%) appeared between 30 and 49 years. Histologically the folliculo-papillary aspect predominated. Thyroid cancer was associated with the following thyreopathies: in 75% of the cases with an anisofollicular adenomatosis, in 12% with a chronic thyroiditis, and in 0.4% with Graves's disease. Only in 13% of the cases no association was found with other thyreopathies. Between 1967 and 1975 no increase of the number of thyroid carcinomas was found.
