甲状腺微小乳头状癌的临床诊疗分析

目的 探讨甲状腺微小乳头状癌(PTMC)的临床诊疗方法.方法 将2009年1月至2010年10月经术后病理确诊的34例甲状腺乳头状癌(PTC)患者分为PIE组(15例,肿瘤>1.0 cm)、PTMC 1组(10例,肿瘤≤0.5 cm)和PIMC 2组(9例,肿瘤0.6～1.0 cm)3组,对3组患者的各项临床资料进行回顾性分析.结果 34例患者超声检查结节内有微小钙化病灶者27例(79.4%),边界不清21例(61.8%),回声不均匀28例(85.3%),结节内有较丰富血流11例(32.4%),3组间超声检查结果差异无统计学意义.均顺利完成手术,其中甲状腺全切术8例,改良颈部淋巴清扫术4例,中央区淋巴清扫术(CLND)30例.PTC组行CLND患者清除淋巴结5(2～30)枚,发生转移9例(60.0%).PTMC组行CLND患者清除淋巴结5(2～13)枚,其中PT-MC 1组清除4(2～6)枚,发生转移3例(30.0%);PTMC2组清除6(2～13)枚,发生转移2例(22.2%).FTC组1例小切口腔镜辅助甲状腺手术患者清除淋巴结6枚,PTMC组5例清除6(2～7)枚,其中PTMC 1组3例清除6(2～6)枚,FTMC 2组2例清除4.5(2～7)枚.经统计学处理,PTC组与PTMC组及PTMC 1组与PTMC 2组之间清除淋巴结情况差异均无统计学意义(P>0.05).全组发生淋巴结转移14例(41.2%),将淋巴结转移患者以45岁为界分成2组,发现PTC组≥45岁的患者转移率(3/3)明显高于<45岁者(2/10)(P=0.035).经术后常规病理证实:3组多发病灶、双侧病灶、腺外侵犯和合并病、淋巴结转移的发生率差异均无统计学意义.结论 超声检查对PTMC的诊断有重要作用,PTMC患者行中央区淋巴清扫术能够明确淋巴结转移情况,有利于后续治疗和随访.

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.
