What does cancer antigen 19-9 mean?

summary

CA19-9 is the symbol of carbohydrate antigen 19-9 and a glycoprotein. It has been known that CA19-9 is a tumor marker, which is distributed in fetal pancreas, hepatobiliary and intestinal tissues during embryonic period; There are also a few in the pancreas and gallbladder of adults. The Serum CA19-9 level in patients with pancreatic cancer, gallbladder cancer, cholangiocarcinoma and digestive tract cancer was significantly increased, so CA19-9 can be used as the main auxiliary index of these cancers.

What does cancer antigen 19-9 mean?

Differential diagnosis of digestive tract diseases (such as pancreatic cancer and pancreatitis). Gastric cancer and gastric ulcer) also have certain value. Increased: in pancreatic cancer, gallbladder cancer, gastric cancer, colon cancer, liver cancer, etc; Acute pancreatitis, cholecystitis, hepatitis also increased in varying degrees. This index can only be used as a reference, only one index can not be diagnosed, or further pathological examination should be done.

Tumor markers are chemical substances that reflect the existence of tumor. Either they do not exist in normal adult tissues, but only in embryonic tissues, or their content in tumor tissues is much higher than that in normal tissues. Their existence or quantitative change can indicate the nature of tumor, so as to understand the histogenesis, cell differentiation and cell function of tumor, and help the diagnosis, classification, prognosis and treatment of tumor.

Tumor indicators reflect the activity of tumor cells in the body. They have great reference value for the diagnosis and treatment of tumors. Some are specific treatment, but some can only be used as reference value. If the above-mentioned examination is increased, it is necessary to exclude the possibility of gastrointestinal tumor, hepatobiliary tumor, etc., and it is necessary to seek medical treatment, Only after the specific situation is clear, can we consider the problem of treatment.

matters needing attention

It can be seen from the above introduction that CA19-9 has little relationship with lung cancer, but the metastasis of lung cancer occurs, and CA19-9 also increases significantly when the above-mentioned cancer occurs. If got lung cancer should be active treatment, radiotherapy is a more effective way to treat tumor, CyberKnife treatment of lung cancer effect is very good, side effects are very small, can be effective treatment.
