摘要
微血管侵犯(MVI)是肝癌具有侵袭性的特征之一,是肝癌肝内及远处转移的独立危险因素。肝癌患者中MVI的发生具有普遍性,且在肝癌不同分期中均可发生,这是多种因素共同作用的结果。这些危险因素包括肿瘤直径、肿瘤形态、肿瘤病理学分级及乙型肝炎病毒活跃与复制等。术前评估存在MVI高危因素患者,应根据患者条件,合理制订手术方案。非解剖性肝切除术尽量扩大切除范围(手术切缘距肿瘤距离>1cm),解剖性肝切除术沿着Glisson系统行完整Laennec囊切除。病理学检查是诊断MVI的金标准,标准化诊断可提高MVI的检出率。MVI主要与肝癌术后早期(1年以内)复发相关,肝癌切除术后MVI阳性患者,选择性联合经导管肝动脉化疗栓塞术、放疗、分子靶向药物等治疗可减少肿瘤的复发,延长肝癌患者无瘤生存时间。因此,MVI对肝癌的综合诊断与治疗具有重要的临床意义。
Microvascular invasion(MVI)is one of the invasive characteristics of hepatocellular carcinoma(HCC)and also an independent risk factor for intrahepatic and distant metastasis of hepatocellular carcinoma.The occurrence of MVI in patients with hepatocellular carcinoma is universal and can occur in different stages of hepatocellular carcinoma,which is the result of the joint action of multiple factors,including tumor diameter,tumor morphology,tumor pathological grading,and hepatitis B virus activity and replication.For patients with preoperative assessment of MVI risk factors,reasonable surgical plans should be made according to the basic conditions of patients.Non-anatomic hepatectomy is performed to expand the resection scope as far as possible(at least>1 cm),and anatomic hepatectomy is performed with complete Laennec cystectomy along the Glisson system.Pathological examination is the gold standard of MVI diagnosis,and standardized diagnosis can improve the detection rate of MVI.MVI is mainly related to early postoperative recurrence of hepatocellular carcinoma(within 1 year).For patients with positive MVI after HCC resection,selective combination with transcatheter arterial chemoembolization,radiotherapy and molecular targeted drugs can reduce tumor recurrence and prolong the survival time of patients with liver cancer without recurrence.Therefore,MVI has important clinical significance for the comprehensive diagnosis and treatment of hepatocellular carcinoma.
