目的評價微波消融(microwave ablation,MWA)同步聯(lián)合經(jīng)動脈化療栓塞(transarterial chemoembolization,TACE)治療大肝癌(直徑>5 cm)和巨塊型肝癌(直徑>10 cm)的安全性和有效性。方法回顧性分析2013年3月至2014年12月期間在復(fù)旦大學(xué)附屬中山醫(yī)院行經(jīng)皮MWA同步聯(lián)合TACE治療的65例大肝癌或巨塊型肝癌患者(腫瘤直徑5～18 cm),治療程序為先行動脈數(shù)字減影血管造影(digital subtraction angiography,DSA),接著超聲引導(dǎo)下行經(jīng)皮MWA,最后行再次血管造影并選擇TACE治療。結(jié)果同步治療耐受性好。造影劑外滲3例,經(jīng)栓塞后消失。術(shù)后僅見輕微肝功能受損和血液毒性及少量的胸腔積液,未見膿腫、膽道損傷、肝功能衰竭及其他手術(shù)相關(guān)的嚴重并發(fā)癥。TACE碘油栓塞劑用量平均為8 mL。隨訪2～21個月,65例患者無疾病進展生存時間為(6.3±1.5)個月,中位生存時間為14個月,6、12及18個月的生存率分別為91.3%、81.5%及48%。2例患者獲得II期手術(shù)切除。結(jié)論MWA聯(lián)合同步TACE治療大肝癌和巨塊型肝癌安全、有效,既可擴大消融的適應(yīng)證,又能減少TACE栓塞劑的用量,是值得推廣的肝癌治療新模式。

肝癌;經(jīng)動脈化療栓塞;微波消融;同步聯(lián)合治療;療效評價

肝細胞肝癌(hepatocellular carcinoma,HCC)是常見的惡性腫瘤,起病隱匿,僅20%～25%的患者適合手術(shù)切除[1]。經(jīng)動脈化療栓塞(transarterial chemoembolization,TACE)是不能手術(shù)切除的中晚期HCC患者首選治療方法[2-5]。大肝癌和巨塊型肝癌由于動脈血供豐富,TACE治療可取得一定的局部療效,但由于患者腫瘤負荷大,單次TACE治療療效有限,需多次重復(fù)TACE治療。即使經(jīng)多次TACE治療,大部分患者的腫瘤仍不能完全壞死,極易在治療期間出現(xiàn)肝內(nèi)和遠處轉(zhuǎn)移,從而嚴重影響TACE的療效和患者生存期。因此,采用以TACE為基礎(chǔ)的聯(lián)合治療能進一步提高大肝癌和巨塊型肝癌介入治療的療效。

腫瘤熱消融治療主要指射頻消融和微波消融(microwave ablation,MWA),具有操作簡單、創(chuàng)傷小、對患者肝功能影響小及并發(fā)癥少的特點,已成為直徑<3 cm的HCC根治性治療方法[6]。但對于大肝癌,消融治療很難使腫瘤完全壞死,尤其是邊緣部位容易殘留腫瘤組織。先采用TACE再序貫消融治療的聯(lián)合治療模式明顯優(yōu)于單一消融治療或TACE治療。Liu等[7]對比了TACE序貫MWA與單一TACE治療直徑>5 cm的HCC患者,發(fā)現(xiàn)聯(lián)合治療在病灶縮小率和生存期方面均明顯優(yōu)于單一 TACE 治療。Xu等[8]報道在直徑>5 cm的HCC治療中,TACE序貫聯(lián)合MWA治療能明顯延長患者總體生存期和腫瘤疾病進展時間。

目前國內(nèi)外尚未見到MWA同步聯(lián)合TACE治療大肝癌和巨塊型肝癌的報道。本文總結(jié)了65例接受MWA同步聯(lián)合TACE治療的大肝癌(直徑>5 cm)和巨塊型肝癌(直徑>10 cm)患者,探討該法治療大肝癌和巨塊型肝癌的安全性和有效性。

資 料 和 方 法

研究對象本研究經(jīng)復(fù)旦大學(xué)附屬中山醫(yī)院倫理學(xué)委員會批準。收集自2013年3月至2014年12月在我院行 MWA 同步 TACE 治療的大肝癌和巨塊型肝癌患者。入選標準:病理證實或符合肝癌臨床診斷標準的HCC患者且腫瘤直徑>5 cm[9];肝功能 Child A或B級;ECOG(Eastern Cooperative Oncology Group)評分≤2分;無出血傾向、凝血功能正?；蚰δ苷系K經(jīng)治療得以糾正者。排除標準:彌漫型肝癌;合并門脈主干至二級分支癌栓或肝靜脈癌栓;合并活動性感染,尤其是膽管系統(tǒng)炎癥等。

動脈造影采用改良Seldinger 法行股動脈穿刺,將5F或4F導(dǎo)管(RH,日本泰爾茂公司)插管至腹腔干或腸系膜上動脈造影(德國拜爾先靈制藥有限公司),明確腫瘤大小、數(shù)目、分布以及供血情況。

超聲引導(dǎo)下MWA根據(jù)CT、MRI或超聲檢查,再結(jié)合肝動脈造影確定擬消融病灶,消融主要針對肝內(nèi)主瘤病灶。B超(型號IPC-1530,日本ALOKA公司)引導(dǎo)下把微波針直接插入腫瘤內(nèi)并接近最遠部,進針選擇避開大血管、膽管、膽囊和腸管的最短路徑,入路上至少應(yīng)有1 cm 的正常肝實質(zhì),開啟電源,MWA儀(型號ECO-100C,南京億高醫(yī)療設(shè)備有限公司)采用水冷循環(huán)單極模式單極針,功率80～100 W,每個位點消融時間5～15 min,消融全程在B超監(jiān)測下進行。前一位點消融結(jié)束后,根據(jù)消融情況退針2～4 cm至下一位點繼續(xù)消融,兩次消融區(qū)域要部分重合,上述過程重復(fù)進行,直至瘤體完全被強回聲覆蓋?；颊咭话憔致榛蛉?根據(jù)腫瘤的大小及部位決定消融位點數(shù)和消融針用量,采用多灶重疊計算消融方案,一般采用雙針多點消融,凝固時間足夠,使壞死范圍加大。消融結(jié)束后電凝狀態(tài)下拔針,電凝穿刺道以防出血和穿刺道腫瘤種植。

再次肝動脈造影消融后再次行肝動脈造影,觀察消融結(jié)果、殘余病灶供血和腫瘤染色,有無造影劑外滲及肝動脈-靜脈瘺等情況。針對殘留病灶行TACE治療,若出現(xiàn)造影劑外滲及肝動脈-靜脈瘺等情況則進一步行相應(yīng)的TACE治療。

TACE治療化療藥(奧沙利鉑50～150 mg,表阿霉素20～50 mg)、超液化碘油(3 ～ 20 mL,法國Guerbet制藥公司)及造影劑混合制成乳劑,通過微導(dǎo)管(商品名:Progreat,日本泰爾茂株式會社)注入殘余腫瘤供血動脈,血流停滯時結(jié)束。對出現(xiàn)造影劑外滲、肝動脈-靜脈瘺患者,給予合適粒徑的明膠海綿顆粒/栓塞微球(商品名:Embosphere,美國Biosphere Medical公司)或微彈簧圈栓塞,如果胸廓內(nèi)動脈、膈動脈等其他血管參與腫瘤供血,則同時進行栓塞。

術(shù)后處理和隨訪術(shù)后24 h監(jiān)測生命體征,同時進行保肝、堿化尿液、預(yù)防感染、營養(yǎng)支持和止痛等治療。術(shù)后3～7天復(fù)查肝腎功能、電解質(zhì)、血常規(guī)以及平掃 CT,對消融程度和并發(fā)癥進行評估。術(shù)后6～7周,患者復(fù)查肝功能、腫瘤標志物(AFP、CEA、CA199等)以及增強 CT 或MRI。按照改良的實體瘤療效評價標準(modified response evaluation criteria in solid tumor,m-RECIST)[10]評估療效,若術(shù)后復(fù)查未出現(xiàn)腫瘤復(fù)發(fā)或肝內(nèi)轉(zhuǎn)移,則患者每7～9周隨訪復(fù)查;若隨訪期間發(fā)現(xiàn)腫瘤壞死不完全或復(fù)發(fā),則根據(jù)患者具體情況再次行 TACE、MWA或 MWA 聯(lián)合 TACE。

討　　　論

對于大肝癌和巨塊型肝癌,單純 TACE 常難以使腫瘤完全壞死,療效有限,患者易出現(xiàn)肝內(nèi)和遠處轉(zhuǎn)移,長期療效并不理想[11-12]。近年來熱消融成為除 TACE 治療外最常用的非手術(shù)治療方法,在小肝癌治療方面療效確切,可作為與外科手術(shù)、肝移植等同的根治性治療。與射頻消融相比,MWA具有導(dǎo)入能量更大、升溫效率更高、消融范圍相對更大、相同消融范圍所需時間更短、腫瘤局部滅活更徹底等優(yōu)點,尤其對大肝癌和巨塊型肝癌,MWA治療具有更強的可操作性,省時、多針多點可達到更大消融范圍,使腫瘤滅活更徹底[13]。對于直徑≤3 cm 的肝癌,MWA與射頻消融都可以取得與手術(shù)切除相同的效果。對于直徑較大的腫瘤,難以保證腫瘤邊緣均達到壞死[14-16],易發(fā)生腫瘤殘存和復(fù)發(fā)轉(zhuǎn)移。對于大肝癌,MWA 完全消融率僅達69%～81.8%[17-18]。Liu等[19]報道直徑>5 cm的病灶經(jīng)MWA后局部復(fù)發(fā)率(40.9%)明顯高于直徑<5 cm的病灶(14%),兩者的局部復(fù)發(fā)率比較差異有統(tǒng)計學(xué)意義(P=0.026)。

MWA序貫聯(lián)合TACE治療HCC已被臨床證實療效顯著優(yōu)于單一MWA治療或TACE治療[7,20-22]。目前臨床上序貫聯(lián)合為先行 TACE 治療,2～4周后行單一MWA治療,TACE可使腫瘤組織血供減少,降低消融時熱量流失,擴大腫瘤MWA的壞死范圍,但由于TACE與MWA之間有較長的間隔時間,TACE治療后可能出現(xiàn)側(cè)支形成、血管再通等情況,因此序貫聯(lián)合不是嚴格意義上的即時性聯(lián)合治療,沒有充分發(fā)揮TACE與MWA之間的協(xié)同治療作用,并且單一MWA后缺乏DSA造影,不能及時發(fā)現(xiàn)并處理消融后出血等可能危及患者生命的嚴重并發(fā)癥。

本研究采用MWA同步聯(lián)合TACE的方式治療大肝癌(直徑>5 cm)和巨塊型肝癌(直徑>10 cm),即先行MWA治療再行TACE治療,取得了良好的臨床療效。同步治療先行MWA滅活大部分腫瘤,明顯減少了TACE時碘油和顆粒型栓塞劑及化療藥物的用量,減輕不良反應(yīng)和肝腎功能的損傷,MWA后行同步TACE所做得DSA造影,可進一步明確消融后殘留腫瘤染色情況,靶向超選擇性插管于殘留腫瘤的供養(yǎng)動脈分支行進一步治療。本組65例患者經(jīng)MWA治療后 TACE 碘油栓塞劑用量均在20 mL以內(nèi)(平均 8 mL),碘油劑用量較單一 TACE 治療明顯減少。65例患者有效率(CR+PR)為93.8%。患者總體無疾病進展生存時間為(6.3±1.5)個月,中位生存期14個月,6、12及18個月的生存率分別為91.3%、81.5%及48%,其中2例患者經(jīng)同步治療后獲得II期手術(shù)切除機會,至隨訪截止日期未見腫瘤復(fù)發(fā)。另外,MWA同步聯(lián)合TACE治療能及時發(fā)現(xiàn)并處理消融后可能出現(xiàn)的并發(fā)癥(如出血、動靜脈瘺等),本組65例患者消融后3例出現(xiàn)造影劑外滲,5例出現(xiàn)動靜脈瘺,給予即時栓塞后均消失。因此,MWA同步聯(lián)合TACE治療能有效滅活腫瘤組織,減少TACE治療時栓塞劑和藥物的使用,減少因大劑量化療帶來的并發(fā)癥,患者獲益明顯。與單一TACE或MWA治療相比,MWA同步TACE治療可以有效地控制疾病進展、延長患者生存時間[23-25]。

本組病例同步治療后未見皮膚燒傷、出血、肝腎功能衰竭等嚴重并發(fā)癥,術(shù)中消融后肝動脈造影見造影劑外滲3例,可能與術(shù)中穿刺有關(guān),給予即時栓塞后消失。術(shù)后大多數(shù)患者只有輕度肝功能受損、栓塞后綜合征(低熱、疼痛、呃逆等)、便秘及少量的胸腔積液,經(jīng)保肝、對癥藥物治療后均緩解。相比單一TACE或MWA,聯(lián)合治療的凝固性壞死更加徹底,肝繼發(fā)性膿腫的發(fā)生率更低。本組研究結(jié)果顯示MWA同步聯(lián)合TACE是安全的,與單一MWA或TACE比較并未明顯增加不良反應(yīng)及嚴重并發(fā)癥的發(fā)生率,與Liang等[26]和Ding等[27]的報道相仿。

綜上所述,MWA同步聯(lián)合TACE治療大肝癌和巨塊型肝癌安全、有效,與單一治療相比并未增加其他不良反應(yīng)及嚴重并發(fā)癥;同步治療可擴大 MWA 的適應(yīng)證,及時處理 MWA 所致的并發(fā)癥(如出血、動靜脈瘺),提高腫瘤壞死率、延長患者總體生存期。本研究的不足之處:(1) 本研究為回顧性研究,隨訪時間短,不足以準確地評價長期療效;(2) 樣本量較小,可能對研究結(jié)果有一定影響。將來擬納入較多的樣本行多中心隨機對照研究。

ObjectiveTo assess the safety and efficacy of microwave ablation (MWA) combined with simultaneous transarterial chemoembolization (TACE) for large (diameter>5 cm) and massive (diameter>10 cm) hepatocellular carcinoma (HCC).MethodsWe reviewed the records of 65 patients with large or massive HCC treated with ultrasound-guided percutaneous MWA with simultaneous TACE between March 2013 and December 2014.The treatment procedure consisted of:initiative digital subtraction angiography (DSA),followed percutaneous MWA under ultrasound and subsequential angiography plus TACE.ResultsThe combination therapy was well tolerated in all patients with transitory hepatic and hematological toxicity and asymptomatic pleural effusion.Contrast agent extravasation was detected in 3 patients and dealt with embolization in time.There was no liver abscess,bile duct injury and other procedure related major complications.The average dosages of lipiodol were 8 mL.During the follow-up period (range 2-21 months),the mean progression-free survival time was (6.3±1.5) months.The median survival time was 14 months.The 6-,12- and 18-month overall survival rates were 91.3%,81.5%and 48%,respectively.Two patients underwent Ⅱ-stage surgical resection after immediate combination therapy.ConclusionsMWA combined simultaneous TACE therapy can be performed safely and effectively in patients without major complications for large and massive HCC.It enlarged the indications of MWA ,and was worth to be promoted.
