求翻译：随着生物工程抗癌新药的陆续上市，靶向治疗越来越多的用于各种癌症的治疗，预计到2015年，全球靶向治疗药物市场规模预计将超过500亿美元，而各公司抗癌药物的研发情况看，靶向治疗药物也已经成为主流。近年来开始研发针对肿瘤干细胞的靶向治疗，但为数不多，尚处于前临床或临床研究阶段。一种有效的靶位从基础研究到进入临床研究阶段，至少需要4-6年时间。介于国外的肿瘤干细胞靶向治疗也是起步不久，加快在此领域的研究，相信还能跟得上主流的。面向我国对抗癌药物的需求增加，而缺乏自主知识产权的难点，相信本项目将为我国靶向治疗药物的开发提供重要理论支持。是什么意思？

As bio-engineering of new anti-cancer drug, and the target market will be more and more to the treatment for a variety of cancer treatment, it is projected that by 2015, the global target for treatment of drug market size is expected to exceed $50 billion, and the company's anti-cancer drugs in the

Along with bio-engineering anti-cancer new medicine one after another going on the market, the target more and more many uses in each kind of cancer to the treatment the treatment, estimated to 2015, the global target to the treatment medicine market scale estimated will surpass 50,000,000,000 US do
