Abstract:
Objective: To evaluate the clinical indications of CD151 in patients with lung adenocarcinoma with positive expressions of vascular endothelial growth factor A (VEGFA) or vascular endothelial growth factor receptor (VEGFR). Methods: The expressions of VEGFA, VEGFR1, VEGFR2 and CD151 in 116 specimens of patients with lung adenocarcinoma after surgery were detected by immunohistochemistry. The association of CD151 expression with the clinical features of patients with lung adenocarcinoma with positive expression of VEGFA or VEGFR was analyzed. The effect of CD151 expression on the disease-free survival (DFS) of patients with lung adenocarcinoma with positive expression of VEGFA or VEGFR was evaluated. Results: The positive rates of VEGFA, VEGFR1, VEGFR2 and CD151 in lung adenocarcinoma tissues were 69.83% (81/116), 69.83% (81/116), 44.83% (52/116), and 42.24% (49/116), respectively. For patients with lung adenocarcinoma with positive expression of VEGFA, positive expression of CD151 was positively correlated with clinical TNM stage (r = 0.24, P = 0.04) as well as lymph node metastasis (r = 0.26, P = 0.02). CD151 was an independent factor predicting DFS of patients with lung adenocarcinoma with positive expression of VEGFA [hazard ratio (HR) = 1.80, 95% confidence interval (CI): 1.00 - 3.19, P = 0.048]. The median DFS of CD151-positive patients with positive expression of VEGFA was significantly shorter than that of CD151-negative patients (20 vs 34 months, P < 0.05). For patients with lung adenocarcinoma with positive expression of VEGFR1, positive expression of CD151 was positively correlated with TNM stage (r = 0.28, P = 0.01) and lymph node metastasis (r = 0.31, P < 0.01). Moreover, CD151 was an independent factor predicting DFS of patients with lung adenocarcinoma with positive expression of VEGFR2 (HR = 2.10 C95% CI: 1.02 - 4.33, P = 0.044), and the median DFS of CD151-positive patients with positive expression of VEGFR2 was significantly shorter than that of CD151-negative patients (21 vs 42 months, P < 0.05). Conclusion: CD151 is an independent factor predicting DFS of patients with lung adenocarcinoma with positive expression of VEGFA or VEGFR2.
