Abstract

Purpose

The present study aimed to assess Lipocalin-2 (LCN2) expression in patients with papillary thyroid cancer (PTC) and to compare it with multinodular goitre (MNG). We also investigated the correlation between LCN2 expression and clinicopathologic characteristics.

Methods

This retrospective study included 63 surgically treated adult patients with papillary carcinoma and 65 adult patients with a MNG. Age, gender, physical, radiological and histopathological examinations, and surgical data of the patients were extracted from the hospital records. Size, histological subtype, capsule invasion, multifocality, extrathyroidal extension (ETE), lymph node metastasis (LNM), and immunohistochemical (IHC) studies of the tumour were recorded from the final histopathological reports of patients with PTC. The patient groups were compared in terms of LCN2 expression. The relationships between LCN2 expression and clinicopathological and other IHC parameters were also evaluated in patients with PTC.

Results

LCN2 expression was significantly higher in the PTC group than in the control group. No significant correlation was demonstrated between LCN2 expression and the presence of multifocal disease, capsular invasion, vascular invasion, ETE, and LNM. There was a moderate positive correlation between LCN2 and human bone marrow endothelial cell marker-1 (HBME-1) expressions, however, no correlation was found between LCN2 and cytokeratin-19 (CK19), CD56, and galectin-3.

Conclusion

LCN2 expression may be a useful biomarker in differentiating benign and malignant lesions of the thyroid gland; however, its expression pattern may not be associated with clinicopathologic characteristics of the PTC and should be investigated in further studies with larger clinical samples.
