小细胞型肺癌(SCLC)系一种低分化的恶性细胞集落,约占全部肺癌病例的20～25％。早期转移、予后恶劣为其特征。近10余年来,对其研究进展显著,发现癌细胞具有急性白血病样的生物学特性,故对化疗、放疗敏感;其某种亚型,甚至已有治愈希望现将国外的治疗近况综述如下。 一,自然病史、增殖动力学和病理学 Small cell lung cancer (SCLC) is a poorly differentiated malignant cell colony that accounts for approximately 20% to 25% of all lung cancer cases. Early metastasis, afterwards is characterized by bad. In the past more than 10 years, significant progress has been made in its research. It has been found that cancer cells have acute leukemia-like biological characteristics and are therefore sensitive to chemotherapy and radiotherapy. Some of their subtypes have even been cured. The current status of foreign treatment is summarized below. First, natural history, proliferation dynamics, and pathology
