title: Significance of survivin, caspase-3, and VEGF expression in thyroid carcinoma.
abstract: To investigate the clinical significance of survivin, caspase-3, and vascular endothelial growth factor expression in a subset of thyroid carcinoma and their correlation with prognosis. Sixty-eight cases of thyroid carcinoma (TC), 12 cases of thyroid adenoma (TA) and 10 cases of normal thyroid tissue (NT) were involved in immunohistochemical and real-time RT-PCR analyses for survivin, caspase-3, and VEGF expression. Statistical analyses were performed for differential expression among NT, TA and TC, correlations of their expression with the clinicopathological parameters of TC including histological typing, clinical staging and lymphnode metastasis, and relationship of survivin with caspase-3 or VEGF in TC. We observed higher mRNA expression and positive immunostaining for survivin and VEGF in TC compared with TA and NT, with a significant positive correlation among them and significant correlations with histological typing, clinical staging and lymphnode metastasis in TC, but we could not find any significance of caspase-3 in TC and its significant relationship with survivin expression. Our results indicate that survivin and VEGF are unfavorable molecules for TC evolution and prognosis, and possess positive correlation in TC.
