Abstract：Objective To summarize the clinical treatment of papillary thyroid microcarcinoma (FTMC). Methods From January 2009 to October 2010,34 patients with PTMC diagnosed by pathology were divided to three groups. Croup papillary thyroid carcinoma (PTC)'s tumor size was larger than 1.0 cm. Croup PTMC Is tumor size was equal or less than 0.5 cm. Croup PTMC 2's tumor size was 0.6-1.0 cm. The clinical data, lymphnod metastasis in neck and operation complication were analyzed. Results By the ultrasonography (US) exam, there were 27 cases(79.4%) of microcalcification, 21 cases (61.8%) of irregular margin and 11 cases (32.4%) of intranodu-lar vascularity. There were no significantly differences in three groups ( P > 0.05 ). All operations were successful. Eight cases underwent total thyroidectomy. Four cases underwent modified radical neck dissection. 30 cases underwent central lymph node dissection(CLND). Among the CLND, 5(2-30) lymphnodes were removed in group PTC, 9 cases (60.0% ) had lymphnode metastasis. 5(2-13) lymphnodes were removed in group PTMC. Among PTMC, 4(2-6) lymphnodes were removed in group PTMC1, 3cases (3/10) had lymphnode metastasis,6(2-13) lymphnodes were removed in group PTMC2 and 2cases(2/9) had lymphnode metastasis. Six cases underwent minimal video-assisted thyroidectomy. There were 14 cases (41.2% ,14/34) of lymphnode metastasis. PTC lymphnode metastasis was 100% (3/3) in age above 45y. Transient hoarseness occured in 7 cases. Transient hypocalcemia occurred in 2 cases. Conclusions Ultrasound plays an important role in diagnosis of PTMC. Performing the centre lymphnode detection with PTMC can verify the lymphnode metastasis and may guide subsequent treatment and follow-ups.
