HBV DNA载量对乙型肝炎相关肝癌手术治疗效果的影响

HBV感染在我国高度流行,长期HBV DNA高载量患者可进展为肝硬化进而导致肝癌的发生。目前,手术仍是治疗乙型肝炎相关肝癌的主要方法。大量研究表明,HBV DNA载量是影响乙型肝炎相关肝癌患者术后肝功能恢复、术后并发症的发生、肝癌复发及肝移植是否成功的重要因素。其机制可能与高HBV DNA载量和HBV再激活相关。通过抗病毒治疗使HBV DNA载量保持一定的低水平状态可改善乙型肝炎相关肝癌患者的预后。综述了术前、术后不同HBV DNA载量对乙型肝炎相关肝癌手术治疗效果的影响,旨在为研究治疗肝癌患者提供参考。     

恶性肿瘤伴乙型肝炎病毒感染患者化学治疗后病毒再激活的临床研究

恶性肿瘤合并慢性乙型肝炎病毒(HBV)感染患者接受化学药物治疗过程中可出现HBV再激活(HBV reactivation),从而加重乙型肝炎病情,并致肝功能损害[1].研究表明,HBV再激活是实体肿瘤化学治疗引起肝功能损害的主要原因[2].本研究通过恶性肿瘤合并HBV感染患者化学治疗后肝功能、HBV DNA载量水平的变化,研究HBV再激活发生的相关危险因素,及核苷类似物抗病毒治疗对肝癌经导管肝动脉化学治疗栓塞术(TACE)后HBV再激活的疗效及影响因素.     

HBV DNA高载量的肝细胞癌患者肝癌根治术后抗病毒治疗疗效观察

目的评估抗病毒治疗对HBV DNA高载量肝细胞癌(HCC)患者根治术后的疗效。方法回顾性分析2007年1月-2010年1月行肝癌根治术的113例伴HBV DNA高载量HCC患者的临床资料,其中74例行抗病毒治疗(治疗组),39例未行任何抗病毒治疗(对照组),均给予基础保肝、支持治疗。对所有患者进行随访,比较2组患者术后HBV DNA定量、肿瘤复发率及生存率差异。组间比较采用t检验或χ2检验,Kaplan-Meier法分析术后生存率,Log-rank检验比较2组术后生存。结果治疗组术后HBV DNA载量持续下降,术后6、12、24个月与术前比较,差异均有统计学意义(t值分别为:14.38、18.50、16.22,P0.05),治疗组与对照组HBV DNA载量分别在术后6、12、24个月差异有统计学意义(t值分别为:13.19、24.20、14.15,P0.05)。2组患者术后3年无瘤生存率差异有统计学意义(P=0.029)。治疗组与对照组的1、2、3年累计生存率分别为:95.95%、85.14%、75.68%和87.18%、69.23%、53.85%,2组术后3年累计生存率差异有统计学意义(P=0.016)。结论对HBV DNA高载量肝癌术后抗病毒治疗可提高肿瘤3年无瘤生存率,延长术后生存期,因此对于HBV DNA高载量HCC患者行肝癌根治术后,宜尽早、规律、持续联合抗病毒治疗。     

肝动脉化疗栓塞术对肝细胞癌患者肝功能和血清HBV DNA的影响

目的观察经导管肝动脉化疗栓塞术治疗肝细胞癌患者肝功能和HBV DNA的变化。方法检测64例肝细胞癌患者在肝动脉化疗栓塞术前后HBV DNA定量及肝功能的变化。结果 64例患者在TACE术前HBV DNA阳性42例(65.6%)。术后2例HBV DNA由阴性转为阳性,21例HBV DNA升高10倍以上。TACE术前42例HBV DNA阳性患者HBV DNA定量为4.3±0.5×104copies/ml,术后44例为6.1±0.4×105copies/ml(P0.05)。HBV激活患者术后肝功能出现明显损害。结论肝动脉化疗栓塞术治疗将引起肝细胞癌患者HBV激活,可能加重肝功能损害,应引起高度重视。     

乙型肝炎病毒对原发性肝细胞癌手术治疗的影响

目的:了解原发性肝癌患者手术治疗对乙型肝炎(HBV)病毒活动状态的影响及HBV的活动状态对原发性肝细胞癌患者手术治疗后肝功能近期变化的影响。方法:采用HBV DNA定量PCR及生物化学方法检测68例HBsAg均为阳性的原发性肝细胞癌手术治疗患者术前、后近期(1个月)HBV DNA的拷贝数,了解HBV活动状态及术前、后近期肝功能的变化进行对比研究。结果:手术治疗后,HBV活跃程度明显增强,HBV拷贝数明显增加,术后组较术前组有显著意义的升高(P<0.01),手术治疗前不同的HBV活跃程度可显著影响治疗后近期肝功能变化,随着HBV活跃程度增强,手术治疗后近期肝功能受损程度也显著增强(P<0.01)。结论:肝癌切除术是目前公认的治疗原发性肝细胞癌的主要手段,本研究显示手术治疗促使HBV复制,HBV复制又导致肝功能的明显损害,HBV活跃程度将对肝癌的手术治疗产生一定负面影响,在强调以手术为主的治疗同时,为了提高手术治疗疗效,要注重术前对HBsAg阳性的患者进行抗病毒药物治疗(包括HBV DNA拷贝数<500的患者),加强营养保肝治疗,提高肝脏储备,尽可能降低HBV活性,术后要密切监测HBV的活性及肝功能变化。     

苦参碱治疗肝癌化疗乙肝病毒再激活的临床观察

研究肝癌化疗对乙肝活动状态的影响及苦参碱的作用。检测89例肝癌患者的血清乙型肝炎病毒标志物及其HBV DNA定量,分为2组,均采用GP方案(吉西他滨 顺铂)化疗,单纯化疗者42例,联合苦参碱者47例,化疗期间、化疗后8周监测HBV DNA及标志物、肝功能。化疗后HBV DNA量较化疗前增加(P<0．01),乙肝病毒再激活与肝炎活动相关,联用苦参碱可减轻肝功能损害,与单纯化疗组相比差异有显著性,但对降低血清HBV DNA载量作用不明显。肝癌化疗可引起乙肝病毒再激活,并导致肝炎活动,苦参碱能保护肝细胞,改善肝功能,对乙肝病毒再激活引起的肝损害有保护作用,但抗病毒作用不明显。     

乙型肝炎相关原发性肝癌术后抗病毒治疗的临床研究

目的比较恩替卡韦(ETV)和阿德福韦酯(ADV)治疗失代偿期乙型肝炎肝硬化对肝功能和甲状腺功能的影响及远期预后。方法选择2013年1月至2015年10月于我院就诊的失代偿期乙型肝炎肝硬化患者98例,随机数表法分为ADV组(49例)和ETV组(49例),分别给予ADV和ETV进行抗病毒治疗,比较两组患者治疗24周后的病毒学指标(如HBV DNA载量、HBV DNA转阴率和HBeAg转换率),48周后的肝纤维化指数、肝功能和促甲状腺激素(TSH)以及死亡率、肝细胞肝癌发生率。结果与治疗前相比,两组患者治疗24周后的HBV DNA载量均明显降低(t=13.694,19.679;P=0.000,0.000)。ADV组相比,ETV组治疗24周后的HBV DNA载量和无应答率较低(t=5.421,P=0.000;χ2=4.438,P=0.035),HBV DNA转阴率和HBeAg转换率较高(χ~2=10.485,6.823;P=0.001,0.009)。与治疗前相比,两组患者治疗48周后的肝纤维化指数、肝功能和TSH均明显降低(t=5.454,10.821,P=0.000,0.000;t=3.222,7.919,P=0.002,0.000;t=3.063,6.830,P=0.003,0.000),其中ETV组的改善程度较ADV组更为明显(t=3.474,4.752,2.935,P=0.001,0.000,0.004)。在随访期间,ADV组和ETV组患者的全因死亡率分别为46.94%和30.61%(χ~2=2.751;P=0.097),Log rank检验显示,ETV组的死亡风险明显低于ADV组(HR=0.547,P=0.042);两组患者的肝癌发生率分别为14.29%和4.08%(χ~2=1.958;P=0.162),ADV组患者的肝癌发生风险明显高于ETV组(HR=0.263,P=0.047)。ADV组和ETV组的不良反应发生率差异无统计学意义(12.24%和6.12%,χ~2=0.489;P=0.494)。结论在治疗失代偿期乙型肝炎肝硬化中应用ETV具有较高的抗病毒疗效,能够有效改善患者的肝功能和甲状腺功能,并显著降低患者的死亡和肝细胞肝癌风险。     

Perioperative reactivation of hepatitis B virus replication in patients undergoing partial hepatectomy for hepatocellular carcinoma

Background and Aim: Reactivation of hepatitis B virus (HBV) replication happens in patients who receive transarterial chemoembolization or systemic chemotherapy for hepatocellular carcinoma (HCC). The incidence and risk factors of HBV reactivation during the perioperative period in HCC patients receiving hepatic resection is unknown. Methods: Between May 2009 and November 2010, 164 consecutive patients with HBV‐related HCC who underwent hepatic resection were prospectively enrolled in the study. Among these, 126 patients received antiviral treatment before the operation (the antiviral group) and 38 patients did not receive any antiviral treatment (the non‐antiviral group). Results: Ten patients (6.1%) developed HBV reactivation perioperatively (within 1 month after hepatectomy). The incidence of HBV reactivation in the antiviral group and non‐antiviral group were 1.6% (2/126) and 21.1% (8/38), respectively (P < 0.001). On univariate analysis, preoperative HBV DNA < 1.0 × 10³ copies/mL and non‐antiviral therapy were significantly correlated with the occurrence of HBV reactivation (P = 0.044 and P < 0.001, respectively). Only non‐antiviral therapy remained as a predictive factor on multivariate analysis (odds ratio, 15.46; 95% confidence interval, 2.80–85.46, P = 0.002). The recovery of liver function (defined as a decrease of alanine aminotransferase back to normal) was achieved in 86.8% (132/152) patients without HBV reactivation and in 37.5% (3/8) patients with HBV reactivation when evaluated on day 30 after hepatectomy (P < 0.001). Conclusion: Hepatectomy could reactivate HBV replication during the perioperative period, especially in patients who did not receive any antiviral therapy. A close monitoring of HBV DNA during the perioperative period was necessary irrespective of the preoperative HBV DNA level. Once HBV was reactivated, antiviral therapy should be given.     

核苷类似物抗病毒治疗对乙型肝炎肝硬化患者血清Th1/Th2型细胞因子水平的影响及临床意义

Antiviral therapies for hepatitis B virus-related hepatocellular carcinoma

Chronic hepatitis B virus(HBV) infection is a critical risk factor for the carcinogenesis and progression of hepatocellular carcinoma(HCC). It promotes HCC development by inducing liver fibrogenesis, genetic and epigenetic alterations, and the expression of active viral-coded proteins. Effective antiviral treatments inhibit the replication of HBV, reduce serum viral load and accelerate hepatitis B e antigen serum conversion. Timely initiation of antiviral treatment is not only essential for preventing the incidence of HCC in chronic hepatitis B patients, but also important for reducing HBV reactivation, improving liver function, reducing or delaying HCC recurrence, and prolonging overall survival of HBV-related HCC patients after curative and palliative therapies. The selection of antiviral drugs, monitoring of indicators such as HBV DNA and hepatitis B surface antigen, and timely rescue treatment when necessary, are essential in antiviral therapies for HBVrelated HCC.

Hepatitis B viral load affects prognosis of hepatocellular carcinoma

Hepatocellular carcinoma(HCC)is a complex disease that is dually challenging to treat due to underlying chronic liver disease in addition to the cancer itself.The prognosis of patients with HCC is determined by intrahepatic tumor status and reserved hepatic function.Hepatitis B virus(HBV)is an established major risk factor of HCC development,and HBV viral load is being increasingly recognized as a prognostic factor in the presence of established HCC.High HBV viral load may affect the prognosis of HBV-related HCC patients in several ways.First,it is associated with more frequent recurrence of HBV-related HCC after treatment.Second,it is associated with more occurrence and severity of potentially life-threatening HBV reactivation.Last,it is associated with more worsened liver function,which limits the therapeutic options for HBV-related HCC.HBV,directly or indirectly,can induce hepatocarcinogenesis.In patients with a high HBV DNA level and subsequent active hepatitis,adhesion molecules expressed on the sinusoidal cells are up-regulated and may increase intrahepatic metastasis.HCC progression after treatment can lead to a poor prognosis by reducing number of normal functioning hepatocytes.Thus,high HBV viral load can affect the prognosis of patientswith HCC by frequent recurrence after treatment for HCC and deterioration of hepatic function associated with HCC progression.Recent meta-analysis showed that antiviral treatment reduces HCC recurrence and liver-related mortality after curative therapy of HCC.Given the strong relationship between high HBV DNA load and poor survival outcome of HCC patients due to cancer progression,it is expected that long-term antiviral therapy results in the sustained HBV suppression,control of inflammation,reduction in HCC progression,and eventually in improved overall survival.     

替比夫定治疗慢性乙肝血清Th1/Th2亚群细胞因子的水平变化

目的探讨慢性乙肝患者接受替比夫定抗病毒治疗后血清T淋巴细胞亚群Th1/Th2细胞因子水平的变化及与肝功能ALT恢复、HBVDNA含量变化及血清HBeAg转换的关系。方法64例HBeAg（＋）慢性乙肝患者接受替比夫定抗病毒治疗,ELISA法检测治疗前及治疗24W后Th1细胞因子IL-2、IL-12及Th2细胞因子IL-4、IL-10的血清浓度变化,并同时检测肝功能ALT、HBVDNA含量的变化及HBeAg血清转换率。结果64例HBeAg（＋）慢性乙肝患者接受替比夫定治疗24W后,有55例患者ALT恢复正常,占85.9%,有34例HBVDNA〈5×10^2copies/ml,HBeAg（-）,占53.1%,治疗52W,有15例发生HBeAg血清学转换,比例为23.4%。治疗组患者血清Th1细胞因子水平低于对照组,Th2细胞因子水平高于对照组,替比夫定治疗后,HBeAg阴转及血清转换患者血清Th1细胞因子浓度比治疗前升高,Th2细胞因子浓度比治疗前降低均有统计学意义（P〈0.05）,ALT恢复正常,HB-VDNA含量下降显著（P〈0.01）。结论T细胞亚群Th1/Th2细胞因子与慢性乙肝替比夫定抗病毒治疗后血清ALT复常,HBVDNA含量下降及HBeAg阴转及血清学转换相关,Th1/Th2亚群细胞因子平衡是促进肝功能ALT恢复、HBVDNA含量下降的重要因素之一,HBeAg高阴转及血清学转换率可能与替比夫定能上调Th1细胞因子水平有关。     

Antiviral therapy decreases viral reactivation in patients with hepatitis B virus–related hepatocellular carcinoma undergoing hepatectomy: a randomized controlled trial

This prospective randomized controlled trial investigated whether antiviral therapy decreases the risk of perioperative viral reactivation in patients with hepatitis B virus–induced hepatocellular carcinoma. Patients with hepatitis B virus–related hepatocellular carcinoma undergoing liver resection were screened. Eighty‐four patients with low viral load were randomly assigned to receive either antiviral treatment with telbivudine or no therapy. The primary outcome was reactivation of viral replication. Secondary outcomes included liver function recovery and postoperative liver insufficiency. A total of 15 patients developed HBV reactivation during the perioperative period, of which 8 (57.1%) were within the first week after hepatectomy. The incidence of viral reactivation during the perioperative period was 2.5% (1/40) in the antiviral‐treated group, compared with 31.8% (14/44) in the control group [HR 0.07 (95%CI 0.01–0.65); P = 0.001]. Liver function recovery was achieved in 82.5% (33/40) patients in the antiviral group on day 30 after hepatectomy, compared with 91.0% (40/44) in the nonantiviral group [HR 1.23 (95%CI 0.98–2.55); P = 0.109]. A total of 7 patients (8.9%) had postoperative liver insufficiency in both groups, but there was no relevant difference between the two groups. Antiviral therapy with telbivudine can significantly decrease the perioperative reactivation of viral replication in patients with hepatitis B virus–related hepatocellular carcinoma undergoing liver resection. Antiviral therapy is an appropriate option for all patients with viral replication undergoing liver resection. (Chinese Clinical Trial Registry, number ChiCTR‐TRC‐0900615).     

肿瘤患者化疗后乙型肝炎病毒再激活病例临床分析

目的观察肿瘤合并慢性HBV携带者化疗后HBV再激活抗病毒治疗的效果及化疗前预防性抗病毒用药对HBV再激活的预防作用。方法采用回顾性分析将13例肿瘤合并慢性HBV携带者分成两组：治疗性用药组8例，为化疗后HBV再激活致肝功能异常者，均停用原有化疗药物，给予拉米夫定100mg／d及保肝药治疗。预防性用药组5例，化疗前即予以拉米夫定100mg／d治疗，待血清HBV DNA水平降至〈10^3拷贝／ml之后再行化疗。随访两组患者的肝功能、HBV DNA水平及预后。结果8例化疗后HBV再激活者，出现肝功能异常后才给予拉米夫定抗病毒治疗，5例因肝功能衰竭而死亡，3例经抗病毒治疗后肝功能恢复，但推迟甚至终止了化疗。5例在化疗前接受预防性抗病毒治疗的患者中未观察到HBV再激活现象，无死亡病例。结论对于需要化疗的HBV携带者，预防比治疗更有意义。
