近年来 ,肺癌的发病率及死亡率逐年上升。随着医疗技术的发展 ,人们发现决定肺癌患者生存期的因素除了病理分型、ＴＮＭ分期以外 ,肿瘤的血管生成情况对预后也有较大影响。许多学者认为肿瘤血管生成 (ｔｕｍｏｒａｎｇｉｏｇｅｎｅｓｉｓ)与肺癌的生物学行为间存在密切的关系。
In recent years, the incidence and mortality of lung cancer have increased year by year. With the development of medical technology, it has been found that in addition to the pathological type and TNM stage, the angiogenesis of the tumor has a great influence on the prognosis. Many scholars believe that there is a close relationship between tumor angiogenesis and the biological behavior of lung cancer.
