High expression of integrin α11 (ITGA11) was associated with higher stages. Expression of ITGA11 in 80 non–small cell lung cancer (NSCLC) patients was analyzed by quantitative RT‐PCR. RNA polymerase II subunit A (POLR2A) was used as internal control. A, Expression of ITGA11 and clinical stage. B, Relationship between the expression of ITGA11 and tumor diameter. Correlation coefficient Rs = 0.009. C, D, Expression of ITGA11 and vascular or lymphatic invasion. Experiments were carried out three times. *P < 0.05
