[Progress in screening and follow-up studies of pulmonary ground glass nodules].

With the wide application of high-resolution chest CT in health check-up, the ground glass nodule(GGN) has been increasingly detected. GGNs have a complex etiology and image features, which can develop fast or very slowly. Therefore, whether to follow up or to resect it is usually very difficult to be determined. Overdiagnosis or overtreatment frequently happens. According to the development of GGNs, the process can be clinically divided into four stages: biological onset stage (pre-detection stage), observational stage, clinical treatment stage and postoperative follow-up stage. This review summarizes the progress on the natural development process, imaging monitoring and differentiation, the optimal time of surgical treatment for GGNs based on the decision of multidisciplinary team. This revie wmay be helpful for clinicians to understand the rule of GGN development in the follow-up, and find an optimal time to give surgical intervention for improving the prognosis of and life quality of the GGN patients.随着高分辨胸部CT的广泛应用，检出的肺磨玻璃结节(GGN)日益增多。GGN病因复杂，影像学表现形式多样，发展变化快慢不一，因此诊疗过程中常难以抉择，过度诊疗或忽视随诊观察常有发生。根据生物学的变化和临床观察诊治过程，可将GGN的发生发展大致分为生物学发病期(发现前期)、随诊观察期、临床治疗期和术后随访期。总结关于肺部GGN随诊中自然发展、影像学监测鉴别、最佳外科诊疗时机和多学科诊疗管理模式的相关研究进展，有助于临床医师掌握其在随诊观察过程中的发展变化规律，把握合适的手术干预时机，改善恶性GGN患者的预后和生活质量。.
