肝細(xì)胞癌和膽管細(xì)胞癌是常見的兩種肝臟腫瘤。不能切除的未經(jīng)治療的膽管細(xì)胞癌患者預(yù)后差，尤其是發(fā)生門靜脈受侵的患者。目前膽管細(xì)胞癌尚無有效的治療手段。射頻消融（radiofrequency ablation， RFA)在不能進(jìn)行手術(shù)切除的肝惡性腫瘤治療中發(fā)揮重要作用，在此，我們報(bào)道成功運(yùn)用射頻消融治療伴有門靜脈癌栓的肝內(nèi)膽管細(xì)胞癌一例，該患者共計(jì)存活26個(gè)月。

病例介紹

肝細(xì)胞癌和膽管細(xì)胞癌是常見的兩種肝臟腫瘤。不能切除的未經(jīng)治療的膽管細(xì)胞癌患者預(yù)后差，尤其是發(fā)生門靜脈受侵的患者，中位生存時(shí)間約為3個(gè)月[1]。主要死亡原因?yàn)榧膊∵M(jìn)展所致肝功能惡化、膽管炎和敗血癥，以及反復(fù)發(fā)作的膽道梗阻[2]。這些病人中大部分患者因?yàn)槁愿尾』A(chǔ)所致肝儲(chǔ)備能力差或者肝內(nèi)有多發(fā)病灶，故僅有少數(shù)患者能夠進(jìn)行手術(shù)切除。射頻消融（radiofrequency ablation，RFA)在不能進(jìn)行手術(shù)切除的肝惡性腫瘤治療中發(fā)揮重要作用，在此，我們報(bào)道成功運(yùn)用射頻消融治療伴有門靜脈癌栓的肝內(nèi)膽管細(xì)胞癌一例。

患者，女性，56歲，主因上腹不適伴有乏力15天入院。體格檢查未見明顯腹痛，既往有高血壓病史，口服降壓藥，血壓控制可。無腫瘤家族史?；?yàn)檢查：谷丙轉(zhuǎn)氨酶(ALT) 45.8U/L，谷草轉(zhuǎn)氨酶(AST) 34.5U/L，總膽紅素12.9umol/L，堿性磷酸酶（ALP）106.2U/L，CA19-9明顯升高，到392.59U/mL (正常值＜37 U/mL)，其余抽血化驗(yàn)均正常。乙肝五項(xiàng)表面抗原、核心抗體陰性，丙型肝炎抗體陰性。腹部CT提示肝左葉病變，伴有門靜脈受侵（圖1）。肝占位穿刺活檢病理結(jié)果為肝內(nèi)膽管細(xì)胞癌，CK19,CD34,P53和CK8/18陽(yáng)性表達(dá)（圖2,3）。對(duì)其施行局部麻醉CT引導(dǎo)下射頻消融治療。

討論

膽管癌是原發(fā)性肝腫瘤中第二常見腫瘤，發(fā)生率高[3-5]。其惡性程度高，各種治療效果差。膽管癌發(fā)生于膽管上皮細(xì)胞，沿著膽管可發(fā)生于任何部位?？煞譃楦蝺?nèi)膽管細(xì)胞癌和肝外膽管細(xì)胞癌[6]。肝內(nèi)膽管癌（ICC）的全球發(fā)病率在最近幾十年來增加了2–6%。肝內(nèi)膽管細(xì)胞癌因缺乏特異性癥狀，在診斷時(shí)多已發(fā)展至晚期，總體預(yù)后比肝外膽管細(xì)胞癌差[7-9]。ICC的診斷仍然是特別具有挑戰(zhàn)性。目前唯一有效的治療方法是手術(shù)。不幸的是，大多數(shù)患者在診斷時(shí)，疾病已經(jīng)發(fā)展至晚期，失去手術(shù)切除機(jī)會(huì)[10-12]。大部分患者因?yàn)槁愿尾』A(chǔ)所致肝儲(chǔ)備能力差或者肝內(nèi)有多發(fā)病灶，故僅有少數(shù)患者能夠進(jìn)行手術(shù)切除[13]。并且，其對(duì)化療也不敏感，大多數(shù)為乏血供腫瘤。肝動(dòng)脈導(dǎo)管化療栓塞（Transarterial chemoembolization，TACE）是通過增加病灶局部化療藥濃度來殺滅腫瘤細(xì)胞，從而減少化療的全身副作用，故其對(duì)ICC的療效很差。不管腫瘤血管分布怎樣，經(jīng)皮射頻消融（RFA）對(duì)于不能手術(shù)切除的腫瘤患者是安全和有效的[14-17]。

在本病例中，患者門靜脈左支受侵。CT引導(dǎo)下RFA治療門靜脈癌栓未見報(bào)道。在這例病例報(bào)告，我們成功完成了ICC合并門靜脈癌栓的肝左葉完全消融。眾所周知，肝癌患者合并有門靜脈癌栓這預(yù)后極差，因?yàn)槟[瘤生長(zhǎng)迅速，常常伴有病灶肝內(nèi)轉(zhuǎn)移、肝功能惡化以及門脈高壓所致上消化道出血等嚴(yán)重并發(fā)癥。Fujii等[18]報(bào)道，合并門靜脈癌栓患者，不管癌栓是在門脈左支、右支或主干，1年生存率為20.9%，2年生存率為6.2%。在本病例中，患者通過RFA聯(lián)合TACE治療，防止門靜脈癌栓蔓延至主干，延長(zhǎng)患者患者的生存期為26個(gè)月。其主要并發(fā)癥為消融術(shù)后6個(gè)月發(fā)生肝內(nèi)膽汁瘤，經(jīng)過經(jīng)皮膽汁瘤引流緩解癥狀?？傊琑FA在一些不能手術(shù)切除的病例中可以成功控制局部腫瘤發(fā)展，在肝腫瘤的治療中發(fā)揮重要作用。

Hepatocellular carcinoma and cholangiocarcinoma are the two most common malignant liver tumors.The prognosis for patients with untreated unresectable cholangiocarcinoma is depressed,especially to the patient with invasion in the portal vein. It has no effective treatment presently. Radiofrequency ablation (RFA) plays an importmant role in the treatment of unresectable liver tumors.It is considered a viable alternative to surgery for inoperable patients. Here,we report the successful use of CT- guided RFA in a patient with intrahepatic Cholangiocarcinoma with invasion in the portal vein.The patient survived for 26 months.
