When CA199 reaches 33.23 million U/L, CT, pathological biopsy and other examinations should be perfected, and if cancer is diagnosed, the lesion should be removed as early as possible, and radiotherapy should be carried out if necessary.
The reference value of CA199 is <37,000U/L, which can be obviously elevated when pancreatic cancer, hepatobiliary and gastrointestinal diseases are present. If CA199 reaches 33,230,000U/L, it should be combined with the patient’s clinical symptoms, and the patient should improve the imaging examination, such as the whole-abdomen enhanced CT, and the pathological examination, such as the gastrointestinal examination to take the biopsy, etc. If the diagnosis is confirmed, the patient should actively treat the disease, and resect the lesion at the earliest possible time, and perform the comprehensive treatment, such as the radiotherapy and chemotherapy, if necessary.
CA199 is the first choice of tumor marker for pancreatic cancer, the sensitivity can reach 80%～90% in early stage, and the positive rate of diagnosing gallbladder cancer, bile duct cancer, gastric cancer and colorectal cancer is also higher, but it has some limitations, and it can be seen to be elevated to different degrees in acute pancreatitis, acute hepatitis and liver cirrhosis.
If CA199 is elevated, patients should reduce anxiety and actively cooperate with the examination and treatment.
