The raising proportion of the papillary thyroid carcinoma, micro-carcinoma, early stage, unilateral multifocal and bilateral lesions is becoming the significant clinical epidemiologic character. Ultrasonography is helpful to detect more and more subclinical tumors, increase the diagnostic accuracy, also guide to identify the clinical stage(T, N stage) before the operation. Ultrasound combined with needle aspiration will be vast diagnostic majority of DTC in the near future in China. Another so important key point during the diagnosis and treatment of DTC is risk-group definition, which can assist to decide the therapeutic protocol and prognostic judgement. Personalized, functional and multidisciplinary therapy based on the risk definition will be the main trends of DTC treatment. Radioiodine, TSH suppression and target therapy will be gradually accepted by clinician. The next prime missions should focus on the professional communication and training，establishing domestic guideline of DTC.
