New method of brain tumor therapy is expected to breakthrough in medicine

WASHINGTON – The medical community has made exciting new breakthroughs in the treatment of deadly brain tumors. Physicians use a modified polio virus to treat patients’ brain cancer. This breakthrough currently looks promising. Pearson reports.

Eight years ago, Stephanie Hower was diagnosed with brain cancer. The doctor surgically removed the tumor but relapsed after two years.

The survival rate of this type of brain cancer patient is very low. After diagnosis, there is only a maximum of one and a half years remaining. Hopper joined an experiment at the Duke University Cancer Institute. They developed a technique that uses the transgenic poliovirus to treat brain cancer.

The modified virus does not cause delirium, but it does shrink tumors. Clinical trials have shown that this method significantly improves the long-term survival of patients with brain tumor recurrence.

With this therapy, 21% of patients had a survival rate of more than three years, while only 4% of brain cancer relapse patients who received standard treatment at the Duke University Research Institute lived for more than three years.

Even a dead polio virus causes a strong immune response. This dead virus is generally used for polio injections.

Dr. Daryl Bignell, Honored Professor of Duke University, is the lead author of this study.

He said: “What we have done is very simple, it is to destroy the ability of the virus to infect nerve cells and no longer cause polio, but it still has the ability to kill cancer cells.”

The doctor injected this modified virus directly into the brain and they repeated the treatment in five patients with recurrent brain cancer.

Dr. Bignell said: “Those patients who we can track long enough have a curative effect after the second injection.”

This treatment method is still in the experiment, but the results seem to be promising. Therefore, doctors started a second study, which is to use poliovirus combined with chemotherapy to improve the treatment results.

For Stephanie, her brain tumor continues to shrink.


However, in response to this news, many visitors have also expressed a lot of questions. The following are the comments of some netizens:

  • Many treatments are aimed at therapies by stimulating the vitality of the immune system rather than directly against viruses, bacteria, or cancer cells. In fact, the principle of chemotherapy is the same. And this method of stimulating the immune system is through some means to slightly damage their own body, very interesting. I personally deeply doubt that the acupuncture of traditional Chinese medicine is actually to stimulate the immune system to achieve the purpose of treatment. Unfortunately, I cannot prove this point. I hope that any scientist who is interested in the Nobel Prize for medicine can prove this point.
  • I have the idea that if we can genetically edit viruses and parasites and let them eat diseased tissue, it’s like using a Maggots to clean up wounds, which may save many people.
  • Does this virus have a mechanism of selective infection of brain cancer cells? If not, this type of therapy is basically fugitive, because if there is no selective infection of cancer cells, normal brain cells will be infected as well, and the human body will quickly become autoimmune after being infected with this virus. In the end, all the viruses were eliminated and the efficacy was zeroed.
