L1CAM and metastatic malignant neoplasm in the lymph nodes: The analysis revealed that H-CTCs (odds ratio [OR] = 1.279, 95% confidence interval [CI]: 0.590-2.539, p = 0.0068), L1CAM expression (OR = 8.372, 95% CI: 3.882-17.350, p = 0.0124), and Ki-67 levels (OR = 4.636, 95% CI: 1.243-10.140, p = 0.0292) were significantly associated with the presence of lymph node metastasis.
