Background:
Using of CD10 in accordance with clinical and histological features of thyroid lesions could be used as both diagnostic and prognostic tool, which consequently influence the management and their prognosis for survival of patients with thyroid neoplasms especially papillary thyroid carcinoma (PTC). The aim of this study was to determine its expression in PTC and different benign thyroid lesions.
Materials And Methods:
In this descriptive-analytic, cross-sectional study, paraffin-embedded tissues of patients with definitive pathologic diagnosis of different benign thyroid lesions and PTC were retrieved. Immunostained sections of each slides was performed using immunohistochemistry methods and expression of CD10 was compared in two groups of benign thyroid lesions and PTC.
Results:
From selected cases 134 sections studied in two groups of PTC (n = 67) and benign thyroid lesions (n = 67). CD10 were immunohistochemically positive in 29.9% of PTC cases, but in none of the thyroid benign lesions (0%) (P < 0.001). There was not significant relationship between expression of CD10 with age and sex of the studied population (P > 0.05).
Conclusion:
The results of the current study indicate that due to the higher expression of CD10 in PTC than benign thyroid lesions it might be used for differentiating mentioned lesions. But for using it as a diagnostic tool further studies with larger sample size and determination of its sensitivity, specificity and cut-off point is necessary.
