肿瘤是严重危害人类健康的疾病之一。目前治疗肿瘤的手段,除药物外,还有外科手术和放射治疗,药物仅占次要地位。据去年第八届国际肿瘤会议上的报告,苏联治疗肿瘤50％是用放射方法,27％用外科手术,其余才是包括药物治疗在内的综合治疗。这恐怕是由于目前已经使用的一些抗肿瘤药物只是对于白血病及淋巴肉瘤等有效,而对一些内脏癌瘤如胃癌、肺癌等多缺乏确实可靠的疗效,同时大多数药物毒性较重,特别是对造血系统的抑制作用很大,因此往往用到一定时期以后就被迫停药,不能解决治疗问题。但这种情况现在看来已逐渐有所改变,抗肿瘤药物的研究近年来迅速发展,疗效较高、毒性较低的新药陆续出现,从而为不断提高药物疗效、减少其毒性提供了可能性,再加上用药方法的改进和旧药的新治疗用 Cancer is one of the serious diseases that endanger human health. At present, in addition to drugs, surgical treatments and radiation therapy are also used in the treatment of tumors. Drugs only play a minor role. According to a report at the 8th International Cancer Conference last year, the Soviet Union treated 50% of tumors with radiation and 27% with surgery. The rest was comprehensive treatment including drug treatment. This is probably due to the fact that some of the antitumor drugs that have been used so far are only effective for leukemia and lymphosarcoma, but they have a definite and reliable effect on visceral cancers such as gastric cancer and lung cancer, and most drugs are toxic, especially Hematopoietic system has a great inhibitory effect, so it is often used after a certain period of time has been forced to stop the drug, can not solve the treatment problem. However, this situation now seems to have gradually changed. The research of anti-tumor drugs has rapidly developed in recent years, and new drugs with higher efficacy and lower toxicity have appeared one after another, thus providing possibilities for continuously improving the efficacy of drugs and reducing their toxicity. Plus the improvement of medication methods and new treatments for old medicines
