UNLABELLED: The pathogenesis of diffuse toxic goiter has not yet been fully understood. The literature increasing commonly focusses on the issues related to the processes occurring in the thyroid gland itself: proliferation, apoptosis, and angiogenesis.
AIM: to investigate clinical and laboratory parameters, as well as the expression of Ki-67, Bcl-2, Bax, Fas-L, CD34, VEGF, and FGF proteins in various postoperative outcomes of patients operated on for diffuse toxic goiter.
SUBJECTS AND METHODS: The investigation enrolled 24 women who had undergone surgery using the technique described by E.S. Drachinskaya. Immunohistochemical tests were carried out according to the standard protocol. The expression of Ki-67, Bcl-2, Bax, Fas-L, CD 34, VEGF, angiopoietin, and FGF proteins was determined.
RESULTS: The patients with postoperative thyrotoxicosis were ascertained to have a significantly greater expression of anti-apoptotic protein Bcl-2, proliferation marker Ki-67, vascular factors (FGF, VEGF), and CD 34.
CONCLUSION: The relative expression area of the anti-apoptotic protein Bcl-2 of more than 2.19 or the proliferation protein Ki-67 of more than 1.059 was found to predict the development of postoperative thyrotoxicosis with an accuracy of higher than 85%.
