A Real-world Study for Patients With Multiple Pulmonary Ground-glass Nodules

A Real-world Study for Patients With Multiple Pulmonary Ground-glass Nodules

The purpose of this study is to actively monitor patients with multiple pulmonary Ground-glass Nodules (GGNs), in order to provide evidence for multiple GGNs treatment.

Multiple pulmonary GGNs are very commonly identified particularly as increasing numbers of CT scans are performed as part of routine lung cancer screening. At the same time, the ideal solution for these cases continues to be debated. This aim of this study is to learn more about the effects of multiple factors on outcome of multiple pulmonary GGNs, such as patients' clinical characteristics, CT features and different pathological types. Furthermore, the optimal timing of surgery and the effect of different surgical choices on the prognosis of patients with multiple GGNs will be investigated.

Inclusion Criteria:

1. Age greater than 18 years
2. Have two or more GGNs on CT imaging
3. Diameter of GGNs > 5mm and ≤ 3cm
4. GGNs must be greater than half ground glass

Exclusion Criteria:

1. patients who have a history of lung cancer
2. patients who have undergone chemotherapy, radiotherapy or targeted therapy before surgery
3. pregnant women
