What is known about the blood cancer case in Vietnam?

If you have spent any significant amount of time on social media in recent weeks, you may have come across posts about scientists officially finding a cure for blood cancer in Vietnam.

The treatment in question is a cell therapy called CAR-T. At first it sounds like very hopeful news, but the reality is a little more modest.

Let me tell you what is known about a blood cancer patient treated in Vietnam.

What is CAR-T cell therapy?

CAR-T cell therapy is a personalized immunotherapy that trains a person’s own immune cells to recognize and destroy cancer.

T cells travel around the body finding and destroying abnormal cells. But sometimes cancer cells can survive by evading T cells. In this treatment, nurses or health workers collect T cells, white blood cells, from the blood. These cells are then sent to a laboratory where scientists modify the T cells to turn them into CAR-T cells. A few weeks later, a serum containing these cells is given back into your bloodstream. The CAR-T cells now recognize cancer cells and attack them.

As with all treatments, CAR-T cell therapy carries some risks of side effects. These include allergic reactions, neurological side effects and an increased risk of infection.

Not an “official remedy”, first applied in Vietnam

And what happened in Vietnam?

In fact, the case in Vietnam does not represent the discovery of a new treatment, but the first application of CAR-T cell therapy in the country.

According to local media, the boy treated in 2025 had a severe form of leukemia and previous attempts at chemotherapy and bone marrow transplants had failed. This time, doctors took the boy’s own immune cells, modified them in the lab to recognize only cancerous cells, multiplied them, and reintroduced them back into his body.

After treatment, the child had a high fever for a few days and was intensively monitored. Later tests showed no cancer cells in the blood.

This is a promising development as it is the first time this has been done successfully in Vietnam.

However, we should say that this development, which is mentioned as “last minute” in many posts on social media in the first week of February 2026, is from 2025. So we cannot talk about the discovery of a “new” treatment, neither in terms of time nor as a development in the world of science.

The treatment has been used for some time in some cases of blood cancer

CAR-T therapy is relatively new but has been used for some blood cancers for some time.

CAR-T has been used for years to treat some types of leukemia and some lymphomas, especially in children. The US Food and Drug Administration (FDA) approved the first CAR T-cell therapy in 2017 for the treatment of children with acute lymphoblastic leukemia (ALL). Since then, other therapies have been approved for the treatment of adults with blood cancers such as non-Hodgkin lymphoma and multiple myeloma. Similarly for certain types of blood cancers in the UK and some European countries.

Yani CAR-T, Vietnam’da geliştirilen yeni bir tedavi yöntemi değil.

Indeed, in response to claims circulating on social media that “blood cancer has been completely cured”, Vietnam’s Ministry of Health emphasized that this represented a local success story, but that the claim that “a new treatment has been found that completely eradicates cancer” was not true.

Sorunlu olan nokta tam burada başlıyor:

It is very wrong to present a first case in a country that worked well in a child as “the definitive cure for blood cancer”. While this example shows that an existing treatment method has been used for the first time on a local scale, it creates a highly inaccurate and exaggerated hope that a new miracle treatment has been discovered and that all cases of blood cancer will now disappear.

Tüm kan kanserleri için evrensel tedavi bulunmadı

Although not yet a 100% successful treatment, research to improve CAR-T cell therapies is advancing rapidly in many countries.

However, this good development in Vietnam does not mean that “there is a definitive cure for blood cancer”. Because at the moment, CAR-T cell therapy is only a treatment option for certain types of blood cancer. In other words, it is not yet a risk-free and definitive solution that works for all types of blood cancer and for everyone. At least for now.

Justin Stebbing, Professor of Biomedical Sciences working in cancer research, explains:

“This treatment is not the first resort for every leukemia patient. Rather, it is a special option that can offer hope for patients who have failed standard treatments or whose disease has relapsed. In such cases, when the alternative may only be palliative care, the introduction of a new line of defense in treatment can change the lives of many people, even if not perfectly.”

Sosyal medyadaki içerikler hasta ve hasta yakınları için kimi zaman umut verirken, kimi zaman hayal kırıklıklarına sebep olabiliyor. CAR-T hücre tedavisi için uygun olabileceğinizi düşünüyorsanız, bunun için en doğru kararı doktorunuz verecektir.

CAR-T treatment is now available in Turkey

Akdeniz University announced the establishment of Turkey’s first CAR-T and Cellular Therapies Production Center in March 2026.

In this way, the entire treatment, which previously mostly required blood samples to be processed abroad, will be carried out in Turkey.

Akdeniz University officials announced that the center plans to accept its first patient on April 15. The center is expected to have the capacity to treat approximately 100-150 patients annually. Turkey will be the eighth country in the world to apply this technique.
