What is the early accuracy rate of pancreatic cancer ca199

In clinical practice, CA199 is the preferred tumor marker for pancreatic cancer and an important indicator for early screening of pancreatic cancer. There is no specific statistical data on the accuracy of CA199 for pancreatic cancer, but generally, the sensitivity of CA199 in early screening of pancreatic cancer can reach 80%~90%, and the specificity is 95%, but there are individual differences.

CA199 is an oligosaccharide tumor-associated antigen. When a patient has pancreatic cancer, his or her CA199 level will increase significantly. The degree of increase varies at different stages of the disease. For most patients, the increase may reach more than 5 times the normal value. Through early screening, the accuracy of judging pancreatic cancer based on the pancreatic cancer CA199 index is relatively high, but there is no specific data statistics, only the sensitivity may reach 80%~90%. Due to individual differences, the examination accuracy of different parts of patients is relatively high, while the examination accuracy of some patients is relatively low. And the increase in CA199 may also be caused by other diseases, including benign diseases and malignant diseases. Among them, benign diseases generally include acute pancreatitis, acute suppurative cholangitis, etc., while malignant diseases include gastric cancer, colorectal cancer, hepatobiliary cancer, etc.

It is recommended to cooperate with the doctor for further examinations. If pancreatic cancer is confirmed, treatment should be started as soon as possible to avoid worsening of the condition and delay in treatment.
