肺癌是全球最常见的恶性肿瘤之一,大约占肿瘤总的死亡人数的17%[1]。近年来尽管肺癌的诊断和治疗取得一定的进展,但其5年总体生存率仍低于15%[2],所以预防和早期诊断是提高肺癌患者存活率的关键[3]。研究表明,肿瘤内微血管计数的高低与肺癌的发生发展、组织类型及生存率有关。
Lung cancer is one of the most common malignancies in the world, accounting for about 17% of the total cancer deaths [1]. In recent years, despite the progress made in the diagnosis and treatment of lung cancer, the 5-year overall survival rate is still below 15% [2]. Therefore, prevention and early diagnosis are the keys to improve the survival rate of lung cancer patients [3]. Studies have shown that the level of tumor microvessel counts with the occurrence and development of lung cancer, tissue type and survival rate.
