Summary
Brief summary (as posted)
This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1006. In this prospective one-arm observational study, bone scintigraphy will be performed in T1N0M0 NSCLC patients with GGO lesion and other low risk factors of bone metastasis. The occurrence rate of bone metastasis in these patients will be analyzed to evaluate the necessity of bone scintigraphy in cT1N0M0 NSCLC patients.
