In detail, the tumor size of retroperitoneal lymph nodes (from 17.77 mm to 3.76 mm) and liver metastasis (from 21.45 mm and 17.69 mm to 16.74 mm and 10.96 mm) in P18 and kidney metastasis (from 10.81 mm and 7.5 mm to disappeared) in P1 were both negatively correlated with the respective APOC3 protein levels. Here, APOC3 is linked to neoplasm.
