近年来,对肺癌进行了较系统的研究,特别是对肺小细胞未分化癌研究较多,文献报告也多,进展较大。肺小细胞未分化癌由于其病理及临床特点,反映了不同于其它病理类型肺癌的生物学特性,形成了一个单独的疾病(Cohen 1978)。肺小细胞未分化癌具有下述特点:①男性多于女性。②症状出现到就诊时间短。③X光检查常常表现为中心型。④多转移,常在初诊时已有转移。⑤手术切除率低,是一个非手术治疗的疾病。⑥对放射线及化疗药
In recent years, more systematic studies have been carried out on lung cancer, in particular, there have been more researches on lung non-differentiated carcinoma of the small cell and there are many reports in the literature. Pulmonary small cell undifferentiated carcinomas, due to their pathological and clinical characteristics, reflect the biological characteristics of lung cancer that are distinct from other pathological types and form a single disease (Cohen 1978). Pulmonary non-differentiated carcinoma of the small cell has the following characteristics: 1 male than female. 2 Symptoms appear short to visit. 3X-ray examination often shows a central type. More than 4 metastases, often at the time of initial diagnosis has been transferred. 5 The low rate of resection is a non-surgical treatment. 6 pairs of radiation and chemotherapeutic drugs
