During physical examination, Lao Wang found a shadow on his right lung. After rechecking the chest CT at the top three hospitals, the CT showed "peripheral lung cancer". The doctor advised him to do a four to five thousand yuan genetic test first, and then target therapies based on the test results.
Pharaoh thought to himself, hasn’t he already been diagnosed, can’t he just operate? Why do we need to do genetic testing? Didn't you want to lie to me for money?
1. Is genetic testing useful?
Of course it works!
Targeted therapy is a new weapon for the treatment of lung cancer. It can kill cancer cells accurately and has good effects in many patients . For example, Lao Wang, his lung cancer was found late, and the lymph nodes next to the lesions were metastasized, so it was extremely difficult to clean directly. The focus can only be reduced through targeted therapy,Consider surgery later. Of course, if the effect is good, surgery may not be necessary.
And genetic testing is the sight of this weapon . Targeting without a sight is blind, and it is very likely to be inaccurate. The same is true for targeted therapy without genetic testing, and its effect will be greatly reduced.
2. What kind of patients need genetic testing?
The main purpose of genetic testing is to guide subsequent targeted therapy, that is to say, All people who are considering targeted therapy need to undergo genetic testing _span 41strong span8.
Our guidelines recommend that patients with advanced lung cancer need genetic testing to guide the choice of targeted drugs .For lung cancer patients in the early and mid-term, although the preferred treatment is now surgery, if targeted therapy is added after the operation, the patient also needs to undergo genetic testing.
3. Targeted therapy is better than radiotherapy and chemotherapy?
The treatment of diseases is changing with each passing day. If we compare the treatment of tumors to war, chemotherapy and radiotherapy are good and bad solutions together. Some good tissues in our body will also be destroyed. If we can survive the tumor, people will win, but this brings The consequence is to kill one thousand enemies and lose eight hundred.
and Targeted therapy is a precise killing, starting from the essence of cancer, which not only treats the symptoms but also cures the cause, has a good effect, and has a lot of side effects on the human body.
Do you want to pump bone marrow? How often will the results come out?
Don’t worry,Not so scary!
Normally, draw a tube of blood from the arm . If it is a patient who has undergone a bronchoscopy biopsy or after surgery, we can also directly use the excised tissue for testing. Generally, the result of the test can be known in about 15 days.
5. Is it enough to do a genetic test?
Some patients will be resistant to targeted drugs after a period of time. Once they are resistant, the drugs will be useless for them. Cancer cells, like the new coronavirus, are constantly mutating. The mutated new coronavirus requires a new vaccine, and the tumor gene that has been mutated after medication also requires new targeted drugs.
In the process of tumor treatment, gene mutations will change. Therefore, in theory, must undergo genetic testing to guide drug selection before each stage of targeted therapy .
In short,If targeted therapy is needed, then genetic testing is still necessary. If the doctor advises you to do it, please consult him carefully, and then get a better understanding of the follow-up treatment plan. After all, it is also a few thousand or even tens of thousands of inspections, and I did it in a muddle, thanks to it~
