1. At present, international clinical trials of lobectomy (wedge resection and segmental resection) are also under way, and the results are also reported. However, the choice of surgical methods for GG0 has been controversial. According to reports, lobectomy is equivalent to lobectomy of early stage IA lung cancer, even there is no GGO lymph node metastasis in stage IA, so it is considered that mediastinal lymph node biopsy is not necessary, but these need to be verified by large sample prospective research results. The reason for raising the above controversy is that I hope everyone can understand the rigor and limitations of medicine, and the development of medicine is spiraling, not moving in a straight line.

2. Back to the current clinical practice, it is very important to predict adenocarcinoma in situ (AIS), microinvasive adenocarcinoma (MIA) or the maximum diameter according to our experience.

3. The surgical method of multiple GGOs at the same time is also a difficult problem. We believe that multiple GG0 belongs to primary lung cancer in the same period, not metastatic lung cancer. Active surgery is the first choice, and a detailed surgical plan is needed. Keep as much healthy lung tissue as possible, and remove GG0 suspected of cancer as much as possible. According to the patient's physical condition, the operation is performed in stages or at the same time. Pathological staging was performed for each GG0 after operation, and the one with the highest staging level was selected to decide the follow-up treatment.

4. Most 4-year-old patients. There is no need for chemotherapy after GG0 operation, and the results of large-scale prospective studies are needed as objective evidence whether targeted drug therapy is needed. Recently, it has been reported that stereotactic radiotherapy (SRT) is used to treat stage I lung cancer. Is stereotactic radiotherapy superior to traditional surgery for early lung cancer? , and published in? The Lancet? Journal, once again triggered a controversy about early lung cancer surgery or stereotactic radiotherapy, many thoracic surgery experts did not question this table. Academic debate will bring scientific progress, and our views on this debate have been described in detail in the short article.

5. Therefore, for GG0, it is necessary to carry out large-scale prospective clinical research, clarify the specific molecular biological mechanism, clarify the individualized and precise surgical methods, clarify the best follow-up treatment plan, and clarify the dispute between radiotherapy and surgery for early tumor GG0. We still have a long way to go, but it's just ahead.

6. The worn glass shadow of the lung, English name GG0, appears as a faint shadow with slightly increased density on CT, which can grow diffusely or only gather locally. Good and evil are inseparable, and most of them are malignant. If it is less than 8 mm, you can follow up. If it exceeds 8 mm, surgery may be needed. Or after active follow-up (more than 3 years), it is found that it has increased, the density has become thicker, and some malignant signs such as cavities and lobulation have appeared, and surgery is recommended. Minimally invasive thoracoscopic surgery is the gold standard for the treatment of GG0. Swollen GG0 is often a low-grade malignant lung cancer.
