随着新的、有效的化学治疗(化疗)药物的发现;对化疗药物的作用,药代动力学和肺癌生物学行为等认识的提高,化疗在肺癌治疗中的应用日趋广泛,以往仅用于不能手术,或晚期肺癌以求暂时性缓解,目前可用于下述几方面: 一、当肺癌诊断成立时,能术疗者仅20％,这些病例即使手术切除后,但治疗也常失败,其主要原因仍为远道转移。放疗也存在同样问题,因胸内病变范围往往较大,不一定收到预期疗效。由于血道、淋巴道内微转移灶存在,小细胞肺癌术后常有赖于全
With the discovery of new and effective chemotherapy (chemotherapy) drugs; the increasing understanding of the role of chemotherapy drugs, pharmacokinetics, and biological behaviors of lung cancer, the use of chemotherapy in the treatment of lung cancer has become increasingly widespread. Can not be surgery, or advanced lung cancer in order to seek temporary remission, can now be used in the following aspects: First, when the diagnosis of lung cancer was established, only 20% of patients can be treated, even after surgery, these cases often failed treatment, its The main reason is still far-reaching. Radiotherapy also has the same problem, because the scope of chest lesions is often larger and does not necessarily receive the desired effect. Due to the presence of micrometastasis in the blood and lymphatic vessels, small cell lung cancer often depends on
