In the words of the INCan specialist, there is a faster response than with chemotherapy and there are fewer side effects.

What happens when all the people with Cancer Are they treated with the same therapy? Should all patients be treated with the same treatments? According to the specialist of the National Cancer Institute (INCan), Omar Macedo, there is a way in which people with Cancer be better served and one of the possible cancer treatments is he targeted therapy o personalized therapy.
During the webinar “Precision Medicine and Cancer“Organized by the Mexican Association for the Fight against Cancer AC, Dr. Macedo mentioned that the personalized guarantees better results, since the type of Cancer that the person has and can receive care according to their needs.

Dr. Macedo revealed that the “traditional” view of treatment against Cancer is treating patients with the same therapy, but that could have several scenarios:
“For some it will work, others will have no effect and others will present a level of toxicity,” explained the specialist, who emphasized that the treatments do not always work.
“The same treatment for each group of diseases is not the best option, since patients may respond differently to the same medication: antidepressants and asthma medications, for example, have a 38% probability of failure, the Diabetes medications have a 43% chance of failure, Arthritis 50%, Alzheimer’s 70% and Cancer 75% ”, explained Dr. Macedo in his presentation.
Under this scheme, Macedo mentioned that precision medicine is more exact in that sense, since a single treatment for all is a stratification where people are grouped by disease, subtypes, demography, clinical aspects and biomarkers; Then there is precision medicine, where an individual patient is personalized and their preferences, clinical aspects, medication history, environment, behaviors and habits and biomarkers are evaluated, which makes “precision medicine” just that, a treatment precise.

For personalized medicine, molecular tests are performed on patients with Cancer And this determines what treatment is for each person, resulting in higher effect levels compared to the traditional approach.
“The traditional approach is no longer recommended. Custom is better. An adequate biopsy allows adequate treatment. The process is that the patient arrives with the doctor, studies are performed, a sample of the tumor tissue is taken (biopsy) and this is sent for review to the pathology where the tumor is named, therefore, molecular tests are requested specific, these molecular tests are performed with RT-PCR (reverse transcriptase polymerase chain reaction) or a sequence of the next generation and the result of tests are given, “explains Macedo.
What are the advantages of this treatment? Dr. Macedo points out that with white therapies, compared to chemotherapy, people have a high response rate, being 60-80% with the former compared to 20-30% for chemotherapies.
“There are faster responses too: in two weeks you start to see results, compared to chemotherapy, where they are seen in six weeks, there are also few adverse effects, there is brain protection against metastasis and therefore better survival,” said the doctor. .
“Don’t be left with the doubt. We are in a good time for oncology and patients should be trained and ask any questions they may have. There are already different ways of treating them, not just the traditional approach, “concluded the expert in these possible cancer treatments.
