The result showed that the concentration of UCB, CB, and TB had a significantly positive correlation with that of albumin (ALB), alanine aminotransferase (ALT), mean corpuscular hemoglobin concentration (MCHC), hematocrit (HCT), red blood cell count (RBC), hemoglobin (HB) (Table 3and Fig. 3D-I). Regarding clinicopathologic features, patients with serum UCB levels above 6.75 μM had a lower percentage of lymph node metastasis compared to those with lower UCB levels (50.2% vs. 61.2%, p = 0.0478, Fig. S3), while CB and TB showed a non-significant trend. The gene discussed is GPT; the disease is metastatic malignant neoplasm in the lymph nodes.
