Abstract
Purpose
In this study, we aimed to investigate the endocan expression in tissue samples of patients diagnosed with Cushing’s syndrome (CS) due to Cortisol-Producing-Adenoma (CPA) and compare it with normal adrenal cortex tissue, and also to evaluate the correlations of endocan expression with clinical and histopathological features.
Methods
11 patients who were operated for CS due to CPA between 2009–2021 and 14 control subjects with normal adrenal cortex were included in the study. Demographic, laboratory and clinicopathological data of the patients were recorded. Sections of 4–5 µm thickness were taken from paraffin blocks of patients diagnosed with CS due to CPA and control subjects with normal adrenal cortex tissue. The sections were then stained in a closed system automatic immunohistochemical staining device to perform immunohistochemical analysis. The endocan positive grade were determined based on the proportion of stained cells on a scale of negative to strong.
Results
The number of subjects with positive endocan expression and the mean endocan expression level in the CS group were significantly higher than the control group (p = 0.005, p < 0.001, respectively). No correlation was found between endocan expression and clinical and histopathological features.
Conclusion
According to the results of our study, endocan overexpression in CPA tissues may be related to the hormonal functionality of CPA.
