RESUMO

RET/PTC oncogene activation occurs in about 20% of human thyroid papillary carcinomas. However, it is not known yet whether it is an early or late event in the process of thyroid carcinogenesis. Here we demonstrate, by using a combined immunohistochemical and reverse transcriptase-polymerase chain reaction based approach, that RET/PTC activation is present in 11 out of 26 occult thyroid papillary carcinomas analysed. Therefore, we conclude that it represents an early event in the process of thyroid cell transformation.

RESUMO

Thyroid glands obtained from patients in southeastern Canada, northeastern Japan, southern Poland, western Colombia, and from Japanese living in Hawaii were serially step-sectioned and examined microscopically using identical techniques and diagnostic criteria. The prevalence of occult papillary thyroid carcinoma was significantly higher in Japan (28.4%) and in Hawaiian Japanese (24.2%) when compared with Canada (6%), Poland (9.1%), and Colombia (5.6%). The carcinomas were all papillary except for a single follicular lesion from Colombia. There was no significant sex prevalence. Most of the patients were between 40 and 79 years of age, but there was no particular predominant decade. Only the Colombian series had a large number of younger patients, and they showed a slightly lower prevalence of occult carcinomas before age 40. Most papillary thyroid carcinomas grow slowly and probably remain occult for the life of the patient.

RESUMO

The authors examined microscopically 110 randomly taken thyroid in serial sections. In 10 cases latent papillary thyroid carcinomas were found. The age and sex were without any influence on the incidence. Latent thyroid carcinomas incidence in this material was similar to that reported from the U.S.A., and Canada, but lower than in Japan and among Japanese population of the Hawaian Islands.
