摘要:目的 研究CT征象聯(lián)合臨床特征在頸淋巴結(jié)陰性單發(fā)的甲狀腺乳頭狀癌患者(Papillary thyroid carcinoma,PTC)中央淋巴結(jié)轉(zhuǎn)移(Central lymph node metastasis,CLNM)情況的預(yù)測(cè)價(jià)值。方法 回顧性分析經(jīng)病理和手術(shù)確診的128例單發(fā)PTC的CT征象及臨床資料,其中CLNM陽(yáng)性者68例,CLNM陰性者60例。利用單因素和多因素回歸分析腫瘤位置、鈣化、與甲狀腺邊緣接觸情況、腫瘤大小、性別、年齡與CLNM的關(guān)系。結(jié)果 回歸分析結(jié)果顯示:腫瘤與甲狀腺邊緣的接觸情況、性別、年齡及腫瘤大小與CLNM顯著相關(guān); 甲狀腺邊緣接觸、年齡<45歲、男性、腫瘤大小直徑>1.0 cm 的患者CLNM陽(yáng)性更常見(jiàn)(P<0.05)。腫瘤位置,鈣化與CLNM無(wú)關(guān)(P>0.05)。結(jié)論 經(jīng)CT征象及臨床資料分析顯示:PTC中CLNM的獨(dú)立危險(xiǎn)因素為甲狀腺邊緣接觸、年齡<45歲、男性和腫瘤直徑大于1.0 cm。

Abstract:Objective To study the predictive value of CT features combined with clinical features in the central lymph node metastasis(Central lymph node metastasis,CLNM)of patients with cervical lymph node-negative thyroid papillary carcinoma(Papillary thyroid carcinoma,PTC).Methods Retrospective analysis of the CT signs and clinical data of 128 cases of PTC diagnosed by pathology and operation,including 68 cases of CLNM positive and 60 cases of CLNM negative.Regression analysis of the location of the tumor,calcification by single and multiple factors,contact with thyroid margin,tumor size,gender,age and CLNM.Results The regression analysis results showed that:the contact,and the edge of the thyroid tumor was significantly related to gender,age and tumor size and CLNM;thyroid edge contact,age<45 years old,male,the size of the tumor diameter>1.0 cm positive CLNM were more common(P<0.05).The location of the tumor,calcification and independent of CLNM(P>0.05).Conclusion The independent risk factor for CLNM in PTC was thyroid marginal contact,age<45 years old,male and tumor diameter greater than 1.0 cm.

目前,盡管甲狀腺乳頭狀癌(PTC)具有相對(duì)惰性的生物學(xué)行為,臨床甲狀腺乳頭狀腫瘤約占惡性腫瘤的80.0%[1]。并且30%~90%的PTC確診是伴有頸部淋巴結(jié)轉(zhuǎn)移,而頸部淋巴結(jié)轉(zhuǎn)移是局部復(fù)發(fā)的重要危險(xiǎn)因素,目前普外科常采用功能性頸部淋巴結(jié)清掃術(shù),但對(duì)于未有中央組淋巴結(jié)轉(zhuǎn)移的患者是否需要功能性淋巴清掃手術(shù),臨床治療手術(shù)方法仍存在爭(zhēng)議[2]。雖然預(yù)防性淋巴結(jié)清掃可減少腫瘤復(fù)發(fā),但常引起甲狀旁腺及喉返神經(jīng)損傷,嚴(yán)重影響患者生活質(zhì)量[3]。因此,對(duì)淋巴結(jié)是否轉(zhuǎn)移準(zhǔn)確識(shí)別顯得越發(fā)重要。目前,臨床上常采用超聲和CT或者螺旋CT檢查進(jìn)行術(shù)前的評(píng)價(jià),由于該手術(shù)術(shù)后預(yù)后一般較好,因此缺乏對(duì)淋巴結(jié)轉(zhuǎn)移規(guī)律特點(diǎn)的研究,尤其對(duì)頸部淋巴結(jié)清掃的適應(yīng)證及影響淋巴結(jié)轉(zhuǎn)移的因素,目前尚無(wú)統(tǒng)一標(biāo)準(zhǔn)[4]?!?br>
