自1969年在日本东京召开的第六届国际化疗大会以来的15年期间,抗肿瘤抗生素的研究与开发对肿瘤化疗的提高做出了很大贡献。例如目前已可用包括抗生素在内的多种抗癌剂治愈睾丸肿瘤、淋巴瘤等恶性肿瘤。此外,自卅二年前首次成功地筛选出第一个抗肿瘤抗生素以来,目前已在微生物的培养物中发现许多新类型的抗癌剂。 During the 15 years since the 6th International Conference on Chemotherapy held in Tokyo, Japan in 1969, the research and development of antitumor antibiotics has greatly contributed to the advancement of chemotherapy. For example, a variety of anticancer agents including antibiotics have been used to cure malignant tumors such as testicular tumors and lymphomas. In addition, since the first successful screening of the first antitumor antibiotic two years ago, many new types of anticancer agents have been found in microbial cultures.
