COPD影像学表型与肺癌关系的研究进展

Study on relationship of COPD radiographic phenotypes and lung cancer

1COPD是一种可预防和治疗的呼吸系统疾病，以气流受限不完全可逆、进行性发展为特征，高分辨率CT能够定量显示早期的肺气肿并进行分级，且能先于肺功能检查发现肺部解剖结构异常。肺癌是最常见的恶性肿瘤之一，研究发现COPD影像学表型可能会增加肺癌的发病风险。该文就COPD影像学表型与肺癌的关系研究进展予以综述，为肺癌的早期预防、诊断提供帮助。

Chronic obstructive pulmonary disease （COPD） is a preventable and treatable respiratory disease, characterized by airflow limitation that is not fully reversible, and that is usually progressive. Emphysema can be shown quantitatively by HRCT at the early stage and then can be classified. HRCT can also detect the abnormal anatomy of lung, prior to pulmonary function test. Studies have shown that COPD radiographic phenotypes could increase the risk of lung cancer, which is one of the most common malignant tumors. This paper reviews the progress on relationship of COPD radiographic phenotypes and lung cancer to provide help for the early prevention and diagnosis of lung cancer.
