What is the carcinoembryonic antigen of lung cancer

summary

I believe many people are familiar with diseases like lung cancer. Once suffering from lung cancer, it will have a great impact on us. We often have cough, chest tightness and other symptoms in the early stage, which we often don't care about. This will lead to the serious plot of lung cancer. Today, I'd like to explain to you the carcinoembryonic antigen of lung cancer.

What is the carcinoembryonic antigen of lung cancer

First, carcinoembryonic antigen is generally used for tumor screening and tumor treatment tracking, which is a dynamic indicator. That is to say, the elevation is not necessarily a tumor, and the tumor is not necessarily elevated. Carcinoembryonic antigen is elevated in some patients with lung adenocarcinoma. But there are other types of lung cancer and early lung adenocarcinoma patients, the index does not rise. The performance of each patient is different. And in the case of infection, immune abnormalities, the tumor index will also increase. Generally speaking, the value of tumor and digestive tract should be more than 3 times higher than the normal value.

Second, the increase of carcinoembryonic antigen is more common in patients with adenocarcinoma, including lung cancer, gastrointestinal cancer and prostate cancer. Carcinoembryonic antigen (CEA) was higher than 300, but the results were not completely parallel with tumor progression and prognosis. It is suggested to further improve the examination to determine whether there is distant lymph node and organ metastasis and analyze the prognosis.

Third: to see what type of lung cancer, if it is adenocarcinoma, CEA is usually higher, and if it is lung squamous cell carcinoma, CEA is often normal, which has little to do with predicting the prognosis of patients, but can evaluate the efficacy of drugs, if taking drugs down, it shows that it is effective.

matters needing attention

In general, cancer patients with elevated tumor markers do not rule out the possibility of recurrence. However, it does not mean that if the tumor markers are high, it must be a recurrence. Do not worry too much. It is recommended that further detailed examination be conducted to exclude the recurrence problem. From the patient's situation, it is recommended to consolidate the treatment for a period of time, no matter whether it is recurrence or not, Can be considered through the treatment of traditional Chinese medicine, Chinese medicine is more peaceful, no side effects, patients are generally acceptable
