BACKGROUND
Cancer of thyroid gland is the most common malignancy of the endocrine system. The treatment improvement could be achieved by early diagnosis. The aim of the study was to identify cancer specific antigenes with use of peptide libraries.
METHODS
The material from 6 patients with thyroid cancer (4 with papillary cancer, 1 with follicular cancer and 1 with oxyphilic tumor) were analyzed. It was performed with use of lipophylic peptide libraries by direct comparison of staining of specimens prepared from normal and malignant tissue.
RESULTS
Preliminary results confirm practical value of peptide libraries in early diagnostics of thyroid cancer.
CONCLUSIONS
It is important to optimize construction of peptide libraries by using different staining agents hydrolyzed by proteases.
