The value of CT signs in combination with clinical materials of single papillary thyroid carcinoma to predict the central lymph node metastasis

Objective To investigate the value of CT signs in combination with clinical materials of papillary thyroid carcinoma (PTC) to predict the central lymph node metastasis (CLNM) . Methods This article reviewed the CT signs and clinical materials of 366 patients with surgically and pathologically verified PTC. The single factor and multi-factor logistic regression analyses were performed on the relation of tumor position, thyroid marginal contact, calcification, plain scan border, border after enhancement, diameter, age and sex with CLNM. Results Among the 366 patients with PTC, the number of patients with positive CLNM and negative CLNM was 155 and 211 respectively. The single factor and multi-factor logistic regression analysis indicated that the thyroid marginal contact, diameter, age and sex were related with CLNM, and the more common patients diagnosed with CLNM had the following features: thyroid marginal contact, a diameter >1.0 cm, age 0.05) . Conclusion The thyroid margin contact, diameter>1.0 cm, age<45 years and males are independent risk factors in diagnosis of positive CLNM.
