近20年来癌症的治疗有了比较迅速的发展,目前药物治癌的疗效水平可以和本世纪初细菌类疾病的化疗水平相近似,其前景是充满希望的。但从国内外在临床上常用的化学合成抗癌药和抗癌抗菌素来看绝大多数都有骨髓抑制、胃肠道反应、使白细胞减少,损害肝肾等较严重的副作用,而化疗药物和抗菌素类在抑制、杀伤癌细胞的同时也能损害正常细胞,还会使由于感染癌症而降低的患者免疫功能进一步受到抑制以致引起危险的继发感染,因此在
In the past 20 years, the treatment of cancer has developed relatively rapidly. At present, the curative effect of cancer treatment can be similar to that of bacterial diseases in the beginning of this century, and its prospects are promising. However, the vast majority of chemically synthesized anticancer drugs and anticancer antibiotics commonly used in clinical practice at home and abroad have myelosuppression, gastrointestinal reactions, leukopenia, and severe liver, kidney, and other side effects, and chemotherapy drugs. Antibiotics can also damage normal cells while inhibiting or killing cancer cells, and they can further inhibit the immune function of patients who have been reduced by infection of cancer, causing dangerous secondary infections.
