[Comparative rate of regional metastasis of high differentiated carcinoma of the thyroid gland].

The rate of metastasis of high differentiated carcinoma of the thyroid glands to the neck lymph nodes was studied in people of Kemerovo Region. The metastatic lesions of pretracheal lymph nodes (VI group) were detected in 49.5% patients with papillary carcinoma and 21.0% of patients with follicular cancer. Metastases in jungular lymph nodes were revealed in 37.3% patients with papillary carcinoma. It was noted that an extension of metastatic lesions of regional lymph nodes was observed in the case of primary tumour foci spread beyond borders of the capsula glandularis in patients with papillary carcinoma. There wasn't such a relation in a case of follicular cancer. Metastases in regional lymph nodes were detected more often (67.6%) in the case of papillary carcinoma in uncontaminated zone of the thyroid gland compared with other thyroid pathology (31.7%).
