该阶段试验的参加者通常是那些肿瘤发生扩散而远离初始位置的人，他们也将因此而有性命之忧。

Participants in such trials are often those whose tumour has spread beyond its original site , and will probably prove fatal .

根治手术仍是首选治疗方案，但术后有复发和转移的可能，大约40-70%的患者术后会出现肿瘤远处扩散。

Radical nephrectomy is the preferred treatment , but after a recurrence and metastasis may be about 40-70 % of the patients with distant spread of metastatic carcinoma .

但是，这也使得肿瘤可以扩散到全身，因此研究人员已经在抗癌中努力寻找停止血管发生的方法。

But it also enables the spread of tumors throughout the body , so researchers have been scrambling for ways to stop angiogenesis in the fight against cancer .

如果该分子被确定为在癌细胞转移其关键作用，并能够作为药物靶标，那么这一发现可能会带来一项预防因肿瘤细胞扩散而导致的死亡的新手段。

If the molecule can be confirmed as a key player in cancer migration , and targeted by drugs , the find may lead to a new preventative measure against the deadly spreading of tumours .
