Mediastinal Lymph Node Dissection Versus Spared Mediastinal Lymph Node Dissection in Stage I GGN NSCLC

Summary

Lung cancer is the leading cause of cancer related death worldwide. Lobectomy or sub-lobectomy with mediastinal lymph node dissection is the standard surgery. About 50% lung nodules are pure ground-glass or part-solid nodules. Non-solid nodules rarely develop mediastinal lymph node metastasis. The present study is a prospective, multicenter and randomized clinical trial, comparing the overall survival and disease-free survival of whether performing mediastinal lymph node dissection in non-small cell lung cancer with ground-glass nodule CT features.
