【摘要】:早期宮頸癌治療的標(biāo)準(zhǔn)術(shù)式是廣泛性子宮切除+盆腔淋巴清掃術(shù)。雖然國(guó)際婦產(chǎn)科聯(lián)盟(FIGO)的宮頸癌臨床分期系統(tǒng)中并沒(méi)有考慮到淋巴結(jié)轉(zhuǎn)移狀態(tài),但盆腔淋巴結(jié)轉(zhuǎn)移是影響宮頸癌治療和預(yù)后的重要因素。因此,盆腔淋巴清掃術(shù)也是宮頸癌根治術(shù)的重要組成部分。系統(tǒng)的盆腔淋巴清掃范圍包括沿盆壁血管切除髂內(nèi)、髂外、髂總、閉孔和宮旁淋巴結(jié)及其周圍的脂肪組織。資料顯示,至少70%的早期宮頸癌患者接受了不必要的盆腔淋巴清掃,由此增加了淋巴囊腫、血管神經(jīng)損傷等手術(shù)并發(fā)癥的發(fā)生率,嚴(yán)重影響了患者術(shù)后的生活質(zhì)量。而且同時(shí)切除了過(guò)多的正常淋巴組織,消除了遠(yuǎn)處轉(zhuǎn)移的第一道屏障,會(huì)引起局部免疫力降低。因此目前對(duì)于不同期別的宮頸癌患者,盆腔淋巴清掃的范圍仍是頗有爭(zhēng)議的問(wèn)題。 髂外末端淋巴結(jié)為旋髂深靜脈至腹股溝韌帶之間沿髂外血管分布的一組淋巴結(jié)。該處淋巴結(jié)數(shù)目比較少,一般為2~5個(gè),而且淋巴結(jié)清除難度較大,切除后易增加術(shù)中出血量、下肢淋巴水腫和淋巴囊腫等手術(shù)并發(fā)癥的發(fā)生率,同時(shí)延長(zhǎng)了手術(shù)時(shí)間。過(guò)去我們?cè)谛g(shù)中常稱之為腹股溝深淋巴結(jié),其實(shí)真正的腹股溝深淋巴結(jié)位于股靜脈上部及股管內(nèi),通常1~4枚,與股動(dòng)、靜脈伴行,不包含在盆腔淋巴結(jié)清掃的范圍內(nèi)。盡管諸多學(xué)者探討過(guò)盆腔淋巴結(jié)和前哨淋巴結(jié)的轉(zhuǎn)移分布規(guī)律,但是對(duì)髂外末端這組淋巴結(jié)研究報(bào)道甚少。 目的 探討早期宮頸癌盆腔淋巴結(jié)和髂外末端淋巴結(jié)轉(zhuǎn)移規(guī)律、相關(guān)危險(xiǎn)因素及其對(duì)預(yù)后的影響,提出早期宮頸癌髂外末端淋巴結(jié)切除的適應(yīng)證及臨床意義。 方法 回顧性分析1995年6月至2011年12月山東省腫瘤醫(yī)院收治的行廣泛子宮切除+盆腔淋巴清掃術(shù)的524例ⅠA~ⅡA期宮頸癌患者的臨床病理資料。所有患者均切除了髂外末端淋巴結(jié)。統(tǒng)計(jì)分析了以下幾個(gè)方面:(1)盆腔淋巴結(jié)轉(zhuǎn)移分布情況;(2)盆腔淋巴結(jié)轉(zhuǎn)移與臨床病理指標(biāo)的關(guān)系;(3)髂外末端淋巴結(jié)轉(zhuǎn)移與臨床病理指標(biāo)的關(guān)系;(4)髂外末端淋巴結(jié)轉(zhuǎn)移與盆腔其他淋巴結(jié)轉(zhuǎn)移的關(guān)系;(5)無(wú)淋巴結(jié)轉(zhuǎn)移組、盆腔淋巴結(jié)轉(zhuǎn)移組與髂外末端淋巴結(jié)轉(zhuǎn)移組的預(yù)后。 結(jié)果 在524例ⅠA~ⅡA期宮頸癌患者中,有盆腔淋巴結(jié)轉(zhuǎn)移的為124例,轉(zhuǎn)移率為23.7%。其中閉孔淋巴結(jié)轉(zhuǎn)移率為16.0%(85/524),髂內(nèi)、髂外淋巴結(jié)轉(zhuǎn)移率為12.2%(64/524),髂總淋巴結(jié)轉(zhuǎn)移率為2.9%(15/524),髂外末端淋巴結(jié)轉(zhuǎn)移率為2.1%(11/524),腹主動(dòng)脈旁淋巴結(jié)轉(zhuǎn)移率為1.7%(9/524)。孤立性髂外末端淋巴結(jié)轉(zhuǎn)移率為0.2%(1/524)。其中IA期無(wú)髂外末端淋巴結(jié)轉(zhuǎn)移;IB1期為0.9%;IB2期為1.3%;ⅡA1為期3.3%;ⅡA2期為2.6%。單變量分析顯示淋巴血管間隙浸潤(rùn)、宮頸肌層浸潤(rùn)深度、臨床分期是盆腔淋巴結(jié)轉(zhuǎn)移的危險(xiǎn)因素(P<0.05);淋巴血管間隙浸潤(rùn)、盆腔其他淋巴結(jié)轉(zhuǎn)移是髂外末端淋巴結(jié)轉(zhuǎn)移的危險(xiǎn)因素(P<0.05)。多因素分析顯示淋巴血管間隙浸潤(rùn)、宮頸肌層浸潤(rùn)深度是盆腔淋巴結(jié)轉(zhuǎn)移的獨(dú)立危險(xiǎn)因素(OR=2.809,95%CI:1.802~4.379;OR=4.093,95%CI:2.196~7.628);盆腔其他淋巴結(jié)轉(zhuǎn)移是髂外末端淋巴結(jié)轉(zhuǎn)移的獨(dú)立危險(xiǎn)因素(OR=29.457,95%CI:3.643~238.176)。早期宮頸癌患者盆腔淋巴結(jié)陰性的5年總生存率為87.9%,伴盆腔淋巴結(jié)轉(zhuǎn)移的5年總生存率降為58.6%。若伴髂外末端淋巴結(jié)轉(zhuǎn)移的1年、2年和3年總生存率分別為50.9%、33.3%、0。 結(jié)論 早期宮頸癌髂外末端淋巴結(jié)轉(zhuǎn)移率較低,其中孤立性髂外末端淋巴結(jié)轉(zhuǎn)移率極低,為減少手術(shù)并發(fā)癥和提高患者的生存質(zhì)量,因此我們認(rèn)為對(duì)ⅠA期或術(shù)中快速病理檢查無(wú)盆腔淋巴結(jié)轉(zhuǎn)移的患者,在切除髂外血管淋巴結(jié)時(shí),,下界至旋髂深靜脈水平,可以考慮保留旋髂深靜脈水平以下的髂外末端淋巴結(jié)。但若術(shù)中快速病理檢查明確有盆腔淋巴結(jié)轉(zhuǎn)移的患者,為降低患者的遠(yuǎn)處轉(zhuǎn)移率,應(yīng)系統(tǒng)仔細(xì)地進(jìn)行盆腔淋巴清掃術(shù),也包括切除髂外末端淋巴結(jié)。
[Abstract]:Pelvic lymph node dissection ( pelvic lymph node dissection ) is an important component of cervical cancer treatment and prognosis . The pelvic lymph node dissection is an important component of cervical cancer treatment and prognosis .
The lymph node of the external iliac artery is a group of lymph nodes distributed along the external iliac blood vessels between the deep iliac vein and the inguinal ligament . The number of lymph nodes is less , usually 2 to 5 , and the operation time is prolonged . In the past we often referred to as the deep inguinal lymph nodes . In the past we often referred to as the deep inguinal lymph nodes . In fact , the true inguinal deep lymph nodes are located in the upper part and the femoral canal of the femoral vein .
Purpose

( 2 ) The relationship between pelvic lymph node metastasis and clinical pathological index ;
( 3 ) The relationship between lymph node metastasis and clinicopathological parameters of external iliac end ;
( 4 ) the relationship between lymph node metastasis and other lymph node metastasis in pelvic cavity ;
