Figure 4From: Risk factors for locoregional recurrence in patients with resected N1 non-small cell lung cancer: a retrospective study to identify patterns of failure and implications for adjuvant radiotherapyComparison between patients with positive and negative lymph nodes at station 10. The difference in freedom from locoregional recurrence (FFLR) rates between patients with resected N1 non–small cell lung cancer and positive or negative lymph nodes (LNs) at station 10 is significant (P = 0.01), showing that a positive LN at station 10 is a risk factor for LR.Back to article page
