Human hepatocellular carcinoma (HCC) is the fifth most common cancer in the world. Currently, surgical resection is the only effective treatment for HCC if the tumor is resectable. Small molecule, biologics and siRNA anti-cancer drugs have been explored for the treatment of HCC. Selective targeting to tumor tissue rather than normal liver in HCC patients is still a challenge. Galactosamine-mediated targeting delivery of anti-cancer drugs in the liver has been tested because its receptor, asialoglycoprotein receptor 1 (ASGPR1), is expressed in the liver and not in other human tissues. We examined ASGPR1 expression levels by immunohistochemistry in HCC with different grades. Guidance for a targeting delivery strategy for anti-cancer drugs to HCC is suggested in this report.
人肝癌(HCC)是全球第五大常见癌症。目前,如果肿瘤可切除,手术切除是 HCC 的唯一有效治疗方法。小分子、生物制剂和 siRNA 抗癌药物已被探索用于 HCC 的治疗。在 HCC 患者中,使抗癌药物选择性靶向肿瘤组织而不是正常肝脏仍然是一个挑战。已经测试了半乳糖胺介导的抗癌药物在肝脏中的靶向递送来治疗 HCC,因为其受体,即去唾液酸糖蛋白受体 1(ASGPR1),在肝脏中表达,而不在其他人体组织中表达。我们通过免疫组织化学检查了不同分级 HCC 中的 ASGPR1 表达水平。本报告提出了一种用于 HCC 靶向递药策略的指导意见。
