Treatment outcomes of lobectomy with and without mediastinal lymph node dissection in older patients with clinical N0 non-small cell lung cancer.

This study demonstrated that MLND does not affect the prognosis of patients with non-small cell lung cancer aged ≥80 years. Lobectomy without MLND is one of the surgical treatment options in older patients with clinical N0 non-small cell lung cancer. Naturally, the clinical stage of patients must be carefully evaluated before surgery.
