【摘要】:目的: 探討超聲引導下粗針穿刺活檢評價微鈣化在甲狀腺癌診斷中的價值。 方法: 1.對62例患者伴有鈣化的甲狀腺結節(jié)疑似病灶行超聲引導下粗針穿刺活檢,活檢結果與手術病理結果對照,分析穿刺活檢結果與術后病理結果是否有差異。 2.根據(jù)結節(jié)內(nèi)鈣化灶的大小,可將其分為粗鈣化(1mm)和微鈣化(≤1mm)比較二者在甲狀腺良惡性結節(jié)中是否有差異。 結果: 1.超聲引導下粗針穿刺活檢準確率96.7%,敏感性96%,特異性100%。 2.微鈣化診斷甲狀腺癌的特異性為95.0%,微鈣化在良性腫瘤與甲狀腺癌中的發(fā)生率比較差異有統(tǒng)計學意義。 3.年齡45歲與≥45歲患者發(fā)生甲狀腺癌伴鈣化者在甲狀腺腫瘤中的比例分別為為90.2%和61.9%,二者有統(tǒng)計學差異。 4.男性甲狀腺癌伴鈣化者發(fā)生率76%,女性甲狀腺癌伴鈣化者發(fā)生率83.8%,二者在統(tǒng)計學上無明顯差異。 結論: 1.超聲引導下甲狀腺粗針穿刺活檢具有較高的準確率、敏感性和特異性。 2.對年齡45歲伴有鈣化,尤其是微鈣化的甲狀腺結節(jié)患者發(fā)生惡性危險性增高,應進一步考慮穿刺活檢,明確病理診斷. 3.微鈣化是甲狀腺癌的特征性征象,但微鈣化并非甲狀腺癌所特有。超聲引導下粗針穿刺活檢可以彌補高頻彩超的不足,顯著提高甲狀腺癌的早期診斷率。對甲狀腺癌具有極高的術前診斷價值,對甲狀腺結節(jié)的治療具有重要的指導意義。
