CA199 is called Glycoantigen 199, and renal cysts will not cause the elevation of this index.
Glycoantigen 199 is a tumor marker, and the abnormal value can be seen in gastric cancer, liver cancer, pancreatic cancer, colon cancer, gallbladder cancer, cholangiocarcinoma and so on, but the diagnosis needs to be combined with the condition of the disease and improve the imaging, pathology and other examinations.
Renal cysts are generally benign structural lesions of the kidney, which usually do not cause CA199 elevation. However, a small number of renal cysts have the possibility of malignancy. If CA199 is found to be abnormal in the examination of patients with renal cysts, it is recommended to further investigate under the guidance of physicians.
It is recommended that patients with renal cysts should undergo regular review, and if other abnormalities are found, they should follow the doctor’s instructions for dynamic observation or further disposition.
