Clinical Application Value of Serum Thyrotropin Level and Tissue Thyrotropin Receptor Detection in Patients with Thyroid Papillary Carcinoma

Objective To investigate the application value of serum thyroid stimulating hormone(TSH)and thyroid tissue thyroid stimulating hormone recepter(TSHR)in papillary thyroid carcinoma(PTC).Methods 55 cases of papillary thyroid carcinoma and 32 cases of nodular goiter were collected.TSH in serum was detected by chemiluminescence method and TSHR expression in thyroid tissue was detected by immunohistochemistry.Results The serum TSH level in PTC was significantly higher than that in nodular goiter,and the difference was statistically significant(χ^2=-2.163,P<0.05).The level of serum TSH in phaseⅢ/Ⅳwas significantly higher than that in phaseⅠ/Ⅱ,and the difference was statistically significant(χ^2=-2.037,P<0.05).There was no significant difference in serum TSH level with age,gender,lymph node metastasis or tumor size(Z=-0.024~1.262,all P>0.05).The positive rate of TSHR in PTC was significantly lower than that in nodular goiter,and the difference was statistically significant(χ^2=4.845,P<0.05).The positive rate ofⅠ/Ⅱphase in PTC was significantly higher than that inⅢ/Ⅳphase,and the difference was statistically significant(Z=-3.097,P<0.05).The expression of TSHR in the non-lymphatic metastasis group was significantly higher than that in the lymphatic metastasis group,and the difference was statistically significant(Z=-2.423,P<0.05).The expression of TSHR had no significant relationship with age,sex and tumor size(Z=-0.846~-1.73,P>0.05).Conclusion Serum TSH level was related to PTC morbidity and TNM staging,the expression of TSHR was related to PTC morbidity,TNM staging and lymphatic metastasis.Both of them can be used as a reference index for PTC diagnosis and prognosis.
