summary

How much do we know about lung cancer! People who often smoke are easy to get lung cancer. It's not good for the lung to live in a smoky environment every day. My uncle is an employee of a chemical factory and also a lung cancer patient. Let's talk about the tumor markers of lung cancer!

What are the tumor markers of lung cancer

First of all: the serum tumor markers related to lung cancer include NSE, SCC, CEA, CA125, CYFRA21-1, etc., but the sensitivity and specificity of these indicators are not high, so their value in the diagnosis of lung cancer is limited, and some tumor markers of lung cancer patients are not high. At present, tumor markers are mainly used to monitor the response to treatment, early monitoring of recurrence, prompt prognosis and other aspects of research, found that suffering from lung cancer after timely treatment, early treatment can be more effective.

Second: CEA: CEA is a fetal protein in adult cancer tissue, which was found in 965. It's an acidic glycoprotein. At first, it was considered as a marker of colon cancer (60% - 90% of patients increased), but later it was found that pancreatic cancer (80%), gastric cancer (60%), lung cancer (75%) and breast cancer (60%) also had high expression. In digestive system cancer, it increases with the progression of the disease.

Finally: neuron specific enolase (NSE): it can be used for auxiliary diagnosis and monitoring the therapeutic effect of small cell lung cancer. When the treatment was effective, the NSE concentration gradually decreased to the normal level, and the NSE increased at the time of recurrence. It was 4-12 weeks earlier to monitor the recurrence with the NSE increase than to determine the recurrence clinically.

matters needing attention

It's very important to prevent lung cancer, so we have to quit smoking and drinking. Smoking not only harms others and ourselves, but also harms others' health. Only after quitting smoking can others not suffer from lung cancer. Environmental pollution is also easy to cause lung cancer, so we must wear masks when we go out.
