[摘要] 目的 比較125I粒子支架與普通膽管支架在不能切除的膽管癌患者姑息治療中的作用。 方法 在PubMed,MEDLINE,EMBASE、Cochrane Library、中國知網(wǎng)數(shù)據(jù)庫系統(tǒng)檢索2000年1月~2019年12月所有關(guān)于對125I粒子支架和普通膽管支架在不能手術(shù)切除的膽管癌治療進(jìn)行療效比較的隨機(jī)對照試驗(yàn)。觀察分析兩組的總膽紅素水平、支架通暢持續(xù)時(shí)間、生存時(shí)間和并發(fā)癥的發(fā)生率。 結(jié)果 與普通支架組相比,125I組術(shù)后的總膽紅素水平顯著降低(P<0.05)、生存時(shí)間(P<0.00001)及支架通暢時(shí)間(P<0.00001)均明顯延長,而并發(fā)癥發(fā)生率(P>0.05)無統(tǒng)計(jì)學(xué)意義。 結(jié)論 與普通支架相比,125I粒子支架可以降低不可切除膽管癌患者的總膽紅素水平,延長支架通暢時(shí)間和患者生存時(shí)間,且不增加并發(fā)癥發(fā)生率,效果更佳。

[Abstract] Objective To compare the effect of 125I particle stent and ordinary biliary stent in palliative treatment of patients with unresectable cholangiocarcinoma. Methods All randomized controlled trials comparing the efficacy of 125I particle stent and ordinary biliary stent in the treatment of surgically unresectable cholangiocarcinoma were retrieved in PubMed, MEDLINE, EMBASE, Cochrane Library, China HowNet database systems from January 2000 to December 2019. The total bilirubin level, duration of stent patency, survival time and incidence of complications in both groups were observed and analyzed. Results Compared with that of the ordinary stent group, the total bilirubin level in the 125I group was significantly reduced(P<0.05), survival time(P<0.00001) and stent patency time(P<0.00001) were significantly prolonged, while the incidence of complications(P>0.05) was not statistically significant. Conclusion Compared with ordinary stents, 125I particle stent can reduce the total bilirubin level in patients with unresectable cholangiocarcinoma, prolong the stent patency time and patient survival time without increasing the incidence of complications, and its effect is better.

膽管癌為起源于膽管上皮細(xì)胞(包括肝內(nèi)、肝門和肝外)的腺癌,死亡率極高,與多種病因有關(guān),例如:乙型肝炎、丙型肝炎、艾滋病、肝內(nèi)膽管結(jié)石、肝硬化、多發(fā)性硬化、膽管炎、寄生蟲感染、化學(xué)致癌物、肥胖、II型糖尿病和非酒精性脂肪肝[1]等。如果僅予以姑息治療,膽管癌患者的中位生存時(shí)間低至2~6個(gè)月?;熀头暖煂颊叩纳嫫谘娱L以及生活質(zhì)量的改善效果并不理想[2],目前經(jīng)皮穿刺或經(jīng)鼻插入膽道支架進(jìn)行姑息性膽管減壓是一種可行的方案[3]。普通塑料支架或金屬支架對不能切除的膽管癌并沒有治療作用,而放射性粒子支架卻可以達(dá)到治療的目的[4]。125I粒子可通過破壞DNA雙鏈螺旋,抑制腫瘤細(xì)胞復(fù)制,誘導(dǎo)CD3+和CD4+細(xì)胞活化,從而誘導(dǎo)腫瘤細(xì)胞凋亡產(chǎn)生抗腫瘤免疫反應(yīng)[5]。本研究通過Meta分析方法對125I粒子和普通膽管支架對不可切除的膽管癌患者的生存結(jié)果、療效和安全性進(jìn)行分析,現(xiàn)報(bào)道如下。
本研究使用Meta分析比較了普通膽道支架和125I粒子支架組對不能切除的膽管癌的影響,發(fā)現(xiàn)與普通支架組相比125I粒子支架組總膽紅素顯著性下降、支架通暢率顯著性增加、患者生存時(shí)間延長,這說明125I粒子支架組可顯著性提高支架通暢率和存活時(shí)間。兩組間并發(fā)癥的比例無顯著性差異,表明125I粒子支架組與普通膽管支架一樣安全,副作用小。
這項(xiàng)薈萃分析首次表明,與普通膽道支架相比,125I粒子支架在不可切除的膽管癌患者中的作用優(yōu)于普通膽道支架,主要體現(xiàn)在它可以降低總膽紅素、延長支架通暢時(shí)間、患者生存時(shí)間、而不增加并發(fā)癥率。這項(xiàng)研究有下列局限性:樣本量較小,125I粒子可能具有潛在的副作用,包括嚴(yán)重疼痛、胰腺炎、膽道穿孔、感染、支架移位,但作者沒有發(fā)現(xiàn)或報(bào)告,也可能是因?yàn)闃颖玖科?。因此,?yīng)進(jìn)行大樣本的精心設(shè)計(jì)的隨機(jī)對照試驗(yàn),并進(jìn)行廣泛的隨訪,以確認(rèn)和更新該分析的結(jié)果。
