The correct name for ca199 is CA19-9, or cancer antigen, and ovarian mucinous cystic adenocarcinoma does not usually show high levels of cancer antigen 19-9.
Cancer antigen 19-9 is a kind of gastrointestinal tumor-associated antigen, which can detect pancreatic cancer, hepatobiliary tract cancer, gastric cancer, colorectal cancer, etc. This marker is more sensitive to pancreatic cancer, so it is helpful for the diagnosis of pancreatic cancer, and it is mainly used as an indicator of recurrence monitoring for the tumor. Therefore, it is not related to ovarian mucinous cystic adenocarcinoma, and usually does not show high cancer antigen 19-9.
High cancer antigen 19-9 is mainly caused by the appearance of tumors in gastrointestinal tract, and it is recommended that patients go to the hospital in time and under the correct operation of the doctor to carry out the examination. Patients with mucinous cystadenocarcinoma of the ovary should also go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying their condition.
