The combination of chemotherapy with immunotherapy, a new treatment in Mexico against lung cancer, increases life expectancy in patients with this condition, Omar Macedo Pérez, a medical oncologist awarded to the Tórax Clinic of the National Cancer Institute (INCan).
When treating patients with them lung cancer Under this clinical protocol, "continuous interest can be achieved, which means that the disease is controlled for years."

In an interview with Notimex, he emphasized that he had increased Life expectancy is 50 per cent in patients.
He warned that lung cancer represents a global health problem caused not only by smoking, but also by chronic smoke smoke exposure and other pollutants. "Globally, it's related to 85 percent to smokeHowever, in Mexico there are different figures, we have 55 percent relating to smoking and a 45 per cent respond to other cases"
That is unfortunately In Mexico, almost 80 percent of lung cancer is diagnosed in advanced stages, which means that the patient is not a candidate for surgical treatment.
We must provide treatment that treats the disease, which improves the symptoms and makes patients live longer ", he says.
At present, he says, we have three strategies to attack lung cancer: the traditional chemotherapy; therapies are empty, where they are used medicines or other substances to identify and tackle certain types of cancer cells that cause fewer harm to normal cells, and the most recent ones where chemotherapy is combined with immunotherapy.
The change of procedure depends on a test that is used to the patient called molecular profile, which includes identifying very specific mutations such as EGFR, ALK; When detected, white therapy is applied – A treatment certificate, where drugs or other substances are used to identify and burst certain types of cancer cells, and which cause fewer harm to normal cells, that is , blocking therapy and these mutations.

If the patient does not have these mutations, which comes to present one in four, the next parameter that we analyze is called TDL1; he encourages us to see what treatment we will do if we are to give him an immunotherapy or we want to give him a combination of chemotherapy with immunotherapy.
To understand this last treatment, it is important to note that more than a month ago, James P. Allison and Tasuku Honjo won the Nobel Prize in 2018 Medicine, to find out about therapy of cancer by regulating the immune system.
His work was crucial to show real potential Immunotherapy as a cancer treatment, and a starting point for developing new clinical trials in patients.
What has been discovered is exactly how it protects itself from immune cells and thanks to discovering, designing drugs from the name of immunizations, which attacks in detail on these cancer protection mechanisms. The immune system comes into a function to attack the tumor cells. That's what immunotherapy currently includes, "explained Macedo Pérez.
In Mexico, immunotherapy is approved for patients with lung cancer. In the INCAN they are present 400 new lung cases every year, and corresponding clinical protocols are applied to determine the type of treatment.
The risk factors, the specialist said, as well as smoking, is the chronic exposure to wood smoke, environmental pollution and chronic lung infections, so it is recommended before a continuous cough for four weeks or more , it is compulsory to go with a pulmonologist to do lung studies.
Also, if the patient has a continuous cough, he has Chest pain, cough with a bloody expectation, these are symptoms that make you think you have a disease and you need a lung or interner assessment.
