目前各类肿瘤的治疗办法有手术、放射、药物治疗和免疫等疗法,但对于绝大多数晚期播散性癌瘤仍以药物治疗为主。现在已有40余种有效的抗癌药物,对10种左右不同类型的肿瘤已有部分病人可以治愈或有希望治愈。但是不能令人满意的是这些药物选择性还较差,特别是对大多数常见肿瘤如肺和消化道等约90种其他癌瘤,还缺少疗效 At present, the treatment methods for various types of tumors include surgery, radiation, drug treatment, and immunity, but the majority of advanced disseminated cancers still rely on drug therapy. There are now more than 40 kinds of effective anti-cancer drugs. Some of the 10 or so different types of tumors have been cured or hopefully cured. However, it is unsatisfactory that the selectivity of these drugs is still poor, especially for most common tumors, such as lung and digestive tract, and about 90 other cancers, but there is still a lack of efficacy.
