Each step within the scientific battle in opposition to most cancers is a profession in opposition to clock: there are loopy cells that multiply with out management and oncologists search manner of anticipating them to get as quickly as attainable to detect them, to deal with them or uncover if any lagging has colonized Other components of the organism. Time is gold and the scientific group is aware of. That is why he has turned a great a part of his efforts to develop instruments to exactly monitor the habits of tumors and anticipate their plans. For instance, by way of liquid biopsy, which detects organic traces of the blood tumor or different fluids.
There are a lot hope deposited on this method, admits Rafael López (65, Vilamarín de Valdeorras, Ourense), head of oncology of the University Hospital of Santiago de Compostela (Chus) and scientific coordinator of a symposium on liquid biopsy that has lately been held In the Galician capital: “It is an important innovation because it makes us change the way of treating and giving prognosis to patients,” assures.
The physician, who has been consulting 4 a long time on the foot of session, seeing most cancers nicely, is alleged “lucky.” At this time he has seen oncology transit to “another world”: of little greater than chemotherapy to deal with a handful of tumors with notorious prognosis, to have a therapeutic arsenal advanced that has managed to double the survival of most cancers. And liquid biopsy is just one extra piece of the gear of that new world that’s being constructed: in apply, for the affected person, this blood take a look at is like an extraction for typical analytics, however that may reveal invaluable details about A tumor.
López, who has additionally simply been appointed president of the Spanish Association of Cancer Research (ASEICA), admits that with liquid biopsy there are nonetheless technical and financial limitations so that every one that potential that consultants predicts to crystallize in medical apply. But it’s optimistic. Solving these obstacles is just a matter of time, the oncologist raises, which serves El País by videoconference from Santiago shortly earlier than the symposium.
Ask. Where is liquid biopsy extra put in?
Answer. It is a method that’s nonetheless between help and analysis. And in that transition, Spain will not be particularly agile to include innovation. It is extra put in in superior lung most cancers to seek for biomarkers that inform us if a affected person goes to answer a remedy or not. Then, it is usually in colon and straight most cancers to see if you will reply to medicine or not. And thirdly, it might be for breast most cancers. But we’ve got greater than 200 tumors and inside every most cancers is early detection, the analysis of preliminary illness, intermediate illness and superior illness. And in every circumstance it has its indications and there are utilities.
P. What are the nice obstacles to carry liquid biopsy to medical apply?
R. It is a set of conditions. One of them is economical: they’re faces. Another limitation is that they’re very advanced proof and we have to perceive how they’re completed, why it’s a must to ask for them and interpret them. And then apply them. In scientific phrases, it’s essential to display in lots of circumstances the medical utility, which is to match it with what we’re doing now.
P. What can say a liquid biopsy on a tumor?
R. It is complementary to tissue biopsy. When we make a tissue biopsy we solely see the material we take, however the subsequent door could be completely different. Instead, liquid biopsy collects every little thing. With the experimental ultrasensitive strategies which can be being investigated, greater than 95% of the tumor data will probably be collected. And in case you have 100 mutations, you can not tackle all of them, we must prioritize them and those that curiosity us are the mutations are drivers [las que conducen a la proliferación del tumor]. Those are those that actually curiosity us and we wish to see the load they’ve as a result of the tumor can be altering and, maybe, at one time it has one or two mutations drivers And, if we assault them, they disappear, however others seem that we’ve got to establish and assault. This is a steady evolutionary sport. With liquid biopsy, by way of a blood take a look at, we anticipate having the ability to establish the weaknesses of just about all tumors.
The future will probably be to observe the affected person’s tumor by way of liquid biopsy, know whether it is and, if it, what weaknesses it has; And, if it adjustments, anticipate “
P. What do they expect to see in the coming years with liquid biopsy? What do they think they can do with liquid biopsy?
R. With liquid biopsy test we will be able to detect much smaller tumors and the treatment that is established at that time will have much more efficiency than the one established now. We will also be able to see if the treatment completely eliminated the tumor or not to be able to give a prognosis and, above all, to, quickly, when it is in less number and size, to be able to apply another treatment in those circumstances. And, in addition, we can inform ourselves what treatment we have to apply. The future will be to follow the patient’s tumor through liquid biopsy, know if it is and, if it, what weaknesses it has; And, if it changes, anticipate.
P. You have assumed presidency of Asaica at a time of paradigm change in cancer. There are, for example, more and more cases in young people. What is happening?
R. Many things escape us and one of them is why we now have cancer in younger people, even in people without bad habits, such as tobacco. We are escaping something and we need to increase research, share everything and work collaboratively. Now we realize that cancer appears in younger people due to epidemiological records, which are records that were taken five years ago. We have to change things to have the data in real time.
P. He has been in the front line against cancer for 40 years. What surprises you most about the behavior of tumor cells?
R. They are very prepared and attempt to escape all of the traps that we put. And, as well as, they offer us repeatedly disagreeable surprises. They are as or extra prepared than the remainder of the physique and that brings us head. And it price us rather a lot to grasp that as a result of for a lot of centuries we thought that most cancers was a static factor and every little thing was the identical. But no: tumors are completely different and continuously change.
