TED演讲:抗击癌症的新式武器(6)

 What's great about this approach is that it can be personalized. 这种方法最大的好处就是可以定制。

We can add many different layers of siRNA to address different mutations and tumor¹ defense² mechanisms³. 我们可以添加多重siRNA，分别针对不同的变异和防御机制。

And we can put different drugs into the nanoparticle core. 我们还可以在内核中放入不同种类的药物。

As doctors learn how to test patients and understand certain tumor genetic⁴ types, 随着医生掌握测试方法，弄清肿瘤的特定基因类型，

they can help us determine which patients can benefit from this strategy and which gene⁵ blockers we can use. 就能帮我们确定哪些病人能使用这种疗法，应该选用哪种基因拦截者。

Ovarian cancer strikes a special chord with me. 我想特别说说卵巢癌。

It is a very aggressive cancer, in part because it's discovered at very late stages, 它是一种非常可怕的癌症，一部分原因是它只有在晚期才能被发现，

when it's highly advanced and there are a number of genetic mutations. 那时病情已经很严重而且伴随很多基因突变。

After the first round of chemotherapy, this cancer comes back for 75 percent of patients. 在首轮化疗结束之后，有75%的患者会复发。

And it usually comes back in a drug-resistant form. 而且复发之后通常都有抗药性。

High-grade ovarian cancer is one of the biggest supervillains out there. 晚期卵巢癌是最大的超级反派之一。

And we're now directing our superweapon toward its defeat. 它是我们的超级武器下一个目标。
