In this study, the serum sLOX-1 and LDL levels in patients with NSCLC were closely related to lymph node metastasis, distant metastasis, and TNM stage (p < 0.001; Table 4) but not to sex, age, smoking history, and histological type (p > 0.05; Table 4). Here, OLR1 is linked to non-small cell lung carcinoma.
