目前化疗药大多数通过直接杀死癌细胞起作用。但研究人员已开始对几种药品进行临床试验,试图用这些药品来改变癌细胞的生物特性而起作用,使其丧失其中一种主要特征—丧失继续分裂的能力。这种情况一旦出现,癌细胞就会最终死亡。新的研究途径以下列试验为根据:癌细胞分化成熟,从而达到停止分裂的发育阶段。这个发现与受到公众承认的观点恰恰相反。通常认为,恶性癌细胞被不可逆地封闭在未成熟的状态,致使细胞无限制地增殖。虽然癌细胞确实有未成熟的特征,但这种情况未必是永恒不变的。据Bert Vogelstein等人认为:甚至原发性肿
Chemotherapy drugs currently play a direct role by killing cancer cells. But researchers have begun clinical trials of several drugs in an attempt to work with these drugs to alter the biological properties of cancer cells, losing one of their main features - their ability to continue dividing. Once this happens, the cancer cells will eventually die. The new research approach is based on the following tests: cancer cells mature, so as to stop the development stage of division. This finding is exactly the opposite of public opinion. It is generally believed that malignant cancer cells are irreversibly blocked in an immature state, causing the cells to proliferate indefinitely. Although cancer cells do have immature features, this may not always be the case. According to Bert Vogelstein and others: even the primary swollen
