Abstract

Objective To explore the relationship between calcium-sensing receptor's expression and papillary thyroid carcinoma.Methods Seventy cases of postoperative papillary thyroid carcinoma were selected.Immunohistochemical technique was used to detect expression of calcium-sensing receptor in papillary thyroid carcinoma,thyroid benign lesions,and normal thyroid tissue,respectively.SPSS 17.0 statistical analysis was used with non parametric test,P<0.05 indicated significant difference.Results The expression of calcium-sensing receptor in papillary thyroid carcinoma,benign thyroid,and normal thyroid were significantly different (90%,40%,0%,respectively; P < 0.05).The expression of the calcium-sensing receptor in the group of papillary thyroid carcinoma with calcification was significantly higher than that in thyroid cancer without calcification (P < 0.05).Conclusions This study suggests that the calcium-sensing receptor may be associated with papillary thyroid carcinoma and may play a key role in the calcification of the carcinoma. Key words: Calcium-sensing receptor; Papillary thyroid carcinoma ; Calcification ; Immunohistochemical
