Risk factors for local recurrence after lobectomy and lymph node dissection in patients with non-small cell lung cancer: Implications for adjuvant therapy

Local recurrence is significantly associated with poor overall survival. Therefore, local control is essential for radical cure of NSCLC. N2 with N1 status was the primary risk factor for local recurrence, while adjuvant chemotherapy improved local control. These data have important implications for postoperative radiotherapy and highlight the need to devise more effective eligibility criteria for this modality in patients with lymph node metastasis.
