As we reported previously [16], we found that AEG-1 was highly expressed in NSCLC (50.7%, P = 0.004) and was positively related to clinical stage (r = 0.164, P = 0.002), lymph node metastasis (r = 0.232, P < 0.001) and tumor size (r = 0.240, P < 0.001). This evidence concerns the gene MTDH and non-small cell lung carcinoma.
