[Current state of the treatment of thyroid cancer].

Individually-tailored approach is recommended in designing the mode of treatment and extent of surgery for thyroid tumors. In cases of papillary and follicular tumors, the main therapy should be surgery to make sure that pre- and paratracheal fat is removed. Radical surgery on the neck is not indicated unless there are metastases.

[Autofluorescence diagnosis of malignant tumors of the head and neck].

A new method for diagnosing human malignant tumors is dealt with, which is based on fluorescence of malignant neoplasms and their adjacent normal tissue. To measure the fluorescence spectra, a fiber optic system and a multi-channel optic spectral analyser have been designed. While analysing the resultant spectra, a greater fluorescence excess was observed in the red wave band in the tumors than in normal tissue.

[Medullary cancer of the thyroid].

The paper deals with a study of 42 cases of medullary carcinoma which accounts for 12.6% of all forms of thyroid cancer. The female-to-male ratio was 1.
