Rab27b Is a Potential Indicator for Lymph Node Metastasis and Unfavorable Prognosis in Lung Adenocarcinoma

Figure 4

Survival analysis of lung adenocarcinoma (LUAD) patients by the Kaplan-Meier method. (a) The overall survival rate in patients with high Rab27b protein expression (green line) was significantly lower than that in patients with low Rab27b expression (blue line). (b) The overall survival rate in patients with positive lymph node metastasis (green line) was significantly lower than that in patients with negative lymph node metastasis (blue line). (c) The overall survival rate in patients with positive N status (green line) was significantly lower than that in patients with negative N status (blue line). (d) The overall survival rate in patients with advanced TNM stage (blue line) was significantly lower than that in patients with early TNM stage (green line).
