导弹在军事上的应用,使许多医学科学家受到启迪,他们联想到肿瘤的治疗问题,如果有一种“导弹”式药物那该多好啊!目前,抗肿瘤药物最多,但真正用于临床的只有三十种左右,而且效果都不甚满意。经过多年临床观察,医学家发现某些对肿瘤细胞有明显杀伤作用的药物往往对正常组织也损害很大。可以设想,如果有某种工具能选择性地将这种威力很大的药物直接运送到靶组织(癌细胞),这样就起到了军事上的“导弹”作用,它既杀伤癌细胞,又对人体正常组织无甚影响。近年来,广大医药学家为寻找抗癌药 The application of missiles to the military has inspired many medical scientists. They think of the treatment of tumors. If there is a “missile” type of drug, how good it is! At present, there are most anti-cancer drugs, but they are really used clinically. There are only 30 or so, and the results are not satisfactory. After many years of clinical observation, medical scientists have found that certain drugs that have a significant killing effect on tumor cells are also very detrimental to normal tissues. It is conceivable that if there is a tool that can selectively deliver this highly potent drug directly to the target tissue (cancer cells), this will act as a military “missile” that will kill cancer cells. It also has no effect on normal human tissues. In recent years, the majority of medical scientists have searched for anti-cancer drugs.
