由于医学、化学的不断进展,很多过去認为的疑难絕症,現在都有可能治疗了。但惡性腫瘤仍繼續严重威胁着人类的生命。从癌症的發展趋势看来,根据統計数字,近年来非但沒有減少,而且是逐年增長着。全世界每年由于癌症而死亡的,超过一百万人。因此,目前在癌的研究方面,各国都非常重視,特別在苏联,对于癌的起因、癌的生物化学变化、癌的治疗等各方面,都进行了很有成效的研究。癌的化学治疗的研究,在近十年来进展非常迅速,出現了很多类型的制癌药。虽然比較理想的、选擇性較高的药物尚少發現,但就已获得的成續来看,对癌症的治疗已开始有了一 Due to the continuous advancement of medicine and chemistry, many of the difficult and incurable diseases that were considered in the past may now be treated. However, malignant tumors continue to pose a serious threat to human life. Judging from the development trend of cancer, according to statistics, not only has it not decreased in recent years, but it has also grown year by year. More than one million people die each year from cancer in the world. Therefore, in the current research on cancer, all countries attach great importance to it. Especially in the Soviet Union, there have been effective studies on the causes of cancer, the biochemical changes in cancer, and the treatment of cancer. Research on the chemotherapy of cancer has progressed very rapidly over the past decade and many types of cancer drugs have emerged. Although less desirable and more selective drugs are still found, the treatment of cancer has already begun to emerge.
