对肺癌的治疗有外科切除,放射治疗与化学疗法,比较早期的用手术可能取得好的成绩,早田等在1970年对日本全国根治切除例5年生存率的统计为25％,而放疗与化疗的疗效较差,前者为5％左右,后者几乎为0％,鉴于肺癌病例大部分是Ⅲ期,Ⅳ期进展的病例,为了提高疗效,考虑进行分段放疗。 The surgical treatment of lung cancer includes surgical resection, radiotherapy and chemotherapy. Compared with early surgery, it may be possible to achieve good results. The early 5-year survival rate of early eradicated radical resection in Japan in 1970 was 25%. Radiotherapy and chemotherapy were used. The efficacy is poor, the former is about 5%, and the latter is almost 0%. Given that most cases of lung cancer are cases of stage III and stage IV progression, in order to improve the efficacy, staged radiotherapy is considered.
