据一项在小鼠、兔子、猪和人肿瘤样本中进行的研究,一种液体制剂可以杀死大量的肝癌细胞并增强化疗的治疗效果。这种液体可为临床医生提供一种较为安全、便宜的“过渡桥梁”,以便在等待肝移植救命的患者中控制肿瘤的发展。化疗仍然是肝细胞癌(HCC)患者的首选治疗,但这些药物对患者的5年存活率并未产生重大影响,后者仍然徘徊在约为9%的极低水平。然而,研究已经证明,肝移植可以大幅改善患者的转归,将5年存活率提高到80%左右。因此,确保得到肝脏移植是临床医生和早期肝癌患者的优先考量,但要找到可供移植的肝脏常常很难。在等待移植期间,临床医生会通过诸如热消融(一种通过加热使癌细胞蒸发的方法)等局部治疗方法来控制肿瘤;但这些方法会占用大量资源、无法适用于所有肿瘤且会损害周围组织。Hassan Albadawi和同事设计了一种名为LATTE的基于一种离子液体的替代消融术,它可将消融制剂和化疗药物直接输送至肿瘤内。该研究组发现,在HCC的大鼠和兔子模型中,单独注射LATTE或与化疗药物阿霉素联用可缩小肿瘤,并能在12个切下的人类肿瘤中快速杀死癌细胞。作者说:“我们预期,LATTE的安全特性、低成本、使用简单及可重复操作的灵活性均能令这一技术受到临床医师的青睐。”
