肝内胆管细胞癌(intrahepatic cholangio carcinoma,ICC)是一种临床恶性肿瘤,其发病率约占原发性肝癌的5%~30%。ICC疾病早期临床病症较为隐匿,出现显著特征时大多已属于晚期,失去了最佳治疗时机[1]。因此,以化疗为主的姑息治疗是延长患者生命期、控制病情进展的主要方式。临床常使用吉西他滨与顺铂药物化疗,虽然能够控制病情,但治疗时间较长。文献[2]指出,由于肝脏转移灶的血供来自肝动脉,因此肝动脉灌注(hepatic arterial infusion,HAI)有助于改善患者血清指标,提高远期生存率。本次研究对本院收治的79例ICC患者分别实施5-氟尿嘧啶(5-FU)+顺铂HAI联合吉西他滨静脉化疗或吉西他滨+顺铂进行全身静脉化疗,对比分析两组临床疗效及生存率状况。

3 讨 论

ICC也被称为周围型胆管细胞癌,是胆管癌的一种组织学类型,主要是指起源于包含二级胆管在内的末梢侧胆道系统的恶性肿瘤[4]。进展期ICC患者临床病症以肝区肿痛、纳差、乏力、消瘦等为主,对患者的生活质量造成严重影响[5]。文献[6-7]指出,进展期ICC具有恶性程度高、病症隐匿、预后差、中位生存期短等特征,手术是治疗ICC的主要措施,胆优于该疾病与肝外胆管细胞癌一样,早期病症较为隐匿,确诊时已属于晚期,失去了手术治疗的最佳时期。临床常通过化疗治疗ICC患者,延长生存期,提高生存质量[8-9]。全身化疗对进展期ICC的作用尚未明确,系统化疗优于一般性支持治疗,作为姑息治疗手段,全身化疗对延长患者生存时间有限,尚未标准的化疗方案。目前,临床治疗进展期ICC的化疗药物主要为吉西他滨、顺铂、5-氟尿嘧啶(5-FU)[10-11]

吉西他滨是一种脱氧胞苷类似物,属于新型细胞周期抗代谢药物,是核糖核苷还原酶抑制剂,主要作用于DNA合成期,用于S期,阻止G1期向S期转化,且在细胞内代谢为活性二磷酸盐,竞争性进入DNA双链终止DNA链复制,诱发细胞凋亡[12-13]。顺铂是细胞毒性类药物,具有较强的广谱抗癌作用,通过抑制细胞有丝分裂,抑制癌细胞的DNA复制,损伤其细胞膜结构。但顺铂联合吉西他滨的化疗后患者的生存期尚未获得显著提高,且治疗时间较长[14-15]

HAI能够直接将5-FU+顺铂药物注入肿瘤供血大动脉内,显著提高肿瘤组织局部的药物浓度,增加杀灭肿瘤细胞数量,同时肝动脉内给药可以减少抗癌药与血浆蛋白结合,缓解局部血流,提高疗效[16-17]。文献[18-19]指出,在动脉灌注时,HAI会增加ICC癌灶局部的化疗药物浓度,约为全身经脉化疗的10~30倍,可杀灭肿瘤细胞。HAI联合吉西他滨具有协同性,能够有效抑制新血管增生,阻止肿瘤增生,消灭播散的亚临床转移灶,缩小局部病灶,降低肿瘤分期[20-21]。本研究中试验组患者的缓解率、获益率均高于对照组患者,且化疗后试验组的CEA、CA199、DKK的水平显著的低于对照组(P<0.05),这说明HAI联合吉西他滨能够有效破坏肿瘤的纤维组织间隔,使得肿瘤组织彻底坏死,抑制迅速发展的癌细胞,改善患者的生存期。本研究发现,试验组患者的1、2年生存率与对照组患者相比均无统计学差异,试验组3年生存率显著的高于对照组,两组患者在化疗过程中出现白细胞降低、血小板减少、肝功能受损、皮疹及口腔黏膜炎等毒副反应的发生率均无统计学意义(P>0.05),这表明进展期肝内胆管细胞癌患者应用HAI结合吉西他滨静脉化疗的效果优于吉西他滨+顺铂进行全身静脉化疗,能够减少肿瘤复发,降低远处转移发生率,增强癌细胞的杀伤敏感性,提高患者机体对毒副作用的耐受性,提高患者生存率。

综上所述,HAI结合吉西他滨全身静脉化疗治疗进展期ICC患者具有显著疗效,能够取得较好的近期疗效,提高远期生存率,不增加毒副反应,值得临床应用。

Abstract Objective: To investigate the clinical efficacy of hepatic arterial infusion (HAI) of 5-fluorouracil (5-FU) and cisplatin combined with systemic intravenous chemotherapy of gemcitabine in treatment of advanced intrahepatic cholangiocarcinoma (ICC).Methods: Seventy-nine patients with advanced ICC and measurable lesions were enrolled and designated to study group (39 cases) and control group (40 cases) by use of a random number table. Patients in study group underwent HAI of 5-FU+cisplatin combined with intravenous gemcitabine chemotherapy, and those in control group underwent systemic intravenous chemotherapy of gemcitabine and cisplatin. Patients in either group

receivedtwo repeated courses of treatment, with one month per course.Results: There was no statistical difference in response rate between study group and control group (38.46% vs.20.00%, P>0.05), but the benefit rate in study group was significantly higher than that in control group (79.49%vs. 60.00%, P<0.05). The levels of tumor biomarkers were significantly decreased in both groups after treatment compared with their pretreatment levels, but their decreasing amplitudes were significantly greater in study group than those in control group (all P<0.05). The 1- and 2-year survival rates showed no statistical difference between study group and control group (63.16% vs. 39.47%; 55.00% vs. 22.50%, both P>0.05), but the 3-year survival rate in study group was significantly higher than that in control group (23.68% vs. 7.50%, P<0.05).There was no statistical difference in incidence of each toxic and adverse reaction during chemotherapy (all P>0.05).Conclusion: HAI combined with systemic intravenous gemcitabine chemotherapy for advanced intrahepatic cholangiocarcinoma patients can achieve relatively good short-term effects and increased long-term survival.
