A micro-device has been developed to select the optimal treatment for glioma
On September 6, 2023, American researchers at Brigham And Women's Hospital announced the development of a micro-device that will help doctors choose the optimal method of treating glioma, a malignant formation that affects the glial cells of the brain or spinal cord.
Glioma is the most common primary brain tumor. Every year in the United States alone, this type of cancer is diagnosed in about 20 thousand people. One obstacle in using targeted glioma therapy is that it is difficult to test many different drug combinations in a short period of time. The new development is designed to solve this problem.
The rice grain-sized device is implanted into the neoplasm and releases small doses of various drug formulations - up to 20 combinations of substances - for two to three hours. The microdevice is then surgically removed and surrounding tumor tissues are sent to the laboratory for analysis. The proposed method, as the authors of the project say, provides an unprecedented opportunity to assess the impact of various drugs on the environment of a malignant formation - that is, on cells that can make up almost half the mass of the entire tumor.
As of early September 2023, the device has been tested on six patients who have undergone brain surgery to remove glioma. Negative side effects from the use of the implant are not recorded. At the same time, the researchers were able to collect valuable biological data - in particular, on how the reaction changes depending on the concentration of the drug and what molecular changes a certain composition causes in cells. In the future, it is planned to implement the device through a minimally invasive procedure 72 hours before the main operation.[1]
Scientists have made a quantum leap in the treatment of a brain tumor
Researchers have discovered a new way to kill cancer cells in hard-to-treat brain tumors. This was announced on September 14, 2023 by the University of Nottingham.
A team of researchers, led by the Faculty of Pharmacy, has discovered a new way to use the unique properties of bio-nanoantennes - gold nanoparticles coated with special molecules. When used correctly, they can cause programmable cell death. The research results were published in the journal Nature Nanotechnology.
Xenografts based on tumor material of patients, in particular glioblastoma cells, were used as material for experiments. The survival rate of patients with this type of cancer is only 6.8%, and the average life after diagnosis is 8 months.
Bio-nanoantennes were able to attack cancer cells and still leave healthy cells unharmed. This result could potentially lead to a new method of surgical treatment of the tumor.
Scientists believe that the use of bio-nanoantennes can be called the first type of "quantum therapy."
| | Our team showed that cancer cells obey the complex dance of electrons organized by the alluring world of quantum biology. With the advent of bio-nanoantennes, the world of quantum therapy has become more real. If quantum biological electrons are modulated accurately, these magnificent nanoparticles create a symphony of electrical signals that act on the self-destruction mechanism in cancer cells, stated Dr. Frenkie Rawson, head of the research team. | |
Researchers have already found the first funds and applied for a patent in order to move on to full-fledged clinical trials. The use of bio-nanoantennes in humans requires more research to ensure the safety and efficacy of the treatment.[2]

Immunotherapy that suppresses the most aggressive type of brain cancer developed
On May 12, 2023, a group of researchers from Uppsala University in Sweden announced the development of a new method to combat glioblastoma - an aggressive brain tumor.
Experts emphasize that there is no effective way to treat this malignant. formations This is partly due to the tumor's ability to suppress or evade the body's natural immune response. In addition, the penetration of drugs into the brain is hindered by the blood-brain barrier, which serves as a highly selective filter.
A new immunotherapy method aimed at treating glioblastoma relies on the use of so-called killer T cells. In brain cancer, blood vessels do not function normally, preventing these cells from entering the tumor. To solve the problem, the researchers used a viral vector that affects the blood vessels of the brain in such a way that they begin to produce a specific factor called LIGHT. As a result, it was possible to transport killer T cells from the blood to the tumor tissue. In addition, the proposed approach creates a favorable environment around blood vessels for therapy.
The researchers also found that their technology contributes to the formation of tertiary lymphoid structures: they are found in neoplasms, where they generate local and systemic antitumor reactions. The results suggest that the new immunotherapy improves the survival rate of patients with glioblastoma.
| | The viral vector needs further development before we can start clinical research, but the results are very promising, "said Professor Magnus Essand, one of the authors of the work.[3] | |
Russian scientists have developed a drug for diagnosing brain tumors with 100% accuracy

This was announced on April 19, 2023 in the RSK group of companies. Read more here.
Nanowire designed to detect brain tumours in urine
In early February 2023, Japanese researchers from the University of Nagoya announced the development of a new technique that allows the detection of malignant brain tumors based on the results of urinalysis.
One of the signs that a person may develop a brain tumor is the presence of extracellular vesicles in the urine associated with malignant formation. These are tiny extracellular vesicles that are released by tissues or organs into their environment. Since certain types of RNA and membrane proteins are present in patients with brain cancer, they can be used to detect a tumor and determine the stage of its progression.
Specialists often detect brain tumors only after the appearance of neurological symptoms, such as loss of movement or speech, when the formation reaches significant sizes. The new method makes it possible to identify cancer at an early stage, which increases the likelihood of successful treatment.
To track extracellular vesicles in urine, Japanese scientists propose using a special device containing nanowires made of zinc oxide. In the process of analysis, extracellular vesicles "stick" to nanowires due to their surface charge and act as a biomarker to determine the presence of a brain tumor. Moreover, this method is suitable for detecting malignancies of any size and at any stage.
| | A liquid biopsy can be performed using different body fluids, but blood tests are invasive. Urine research is an effective, simple and painless method that can be used to detect various diseases, including brain tumors, "said Takao Yasui, one of the authors of the project.[4] | |

Infrared implant developed to treat brain cancer
On October 13, 2022, it was reported that researchers at Stanford Medical University had developed and tested a wireless device to treat brain cancer.
Brain tumors are among the most deadly and intractable cancers. Glioblastoma, a particularly aggressive form, kills more than 10,000 Americans a year, and the average survival time is less than 15 months.
For patients with brain tumors, treatment usually involves surgery on an open skull to remove as much of the tumor as possible, followed by chemotherapy or radiation that comes with serious side effects and numerous hospital visits.
A new study by Stanford scientists has developed a less invasive treatment for brain tumors that, in trials in mice with brain tumors, significantly increased their survival time. This required only 15 minutes of treatment a day for 15 days, with the mice engaged in their usual activities.
The method is based on a new way to fight various types of cancer, involving the introduction of nanoparticles into the tumor, and then their heating. Exposure can occur through an electromagnetic field, ultrasound or light, and because cancer cells are more sensitive to heat than healthy cells, it allows them to be killed with minimal damage to surrounding tissues.
Developed by Stanford University, the device implants between the skin and skull and emits infrared light when turned on. Star-shaped gold nanoparticles are injected into a brain tumor through a tiny hole in the skull, and infrared light from the device heats them up to 5C. After several sessions of such treatment, the cancer cells were successfully destroyed.
The team says adjusting infrared power as well as the wavelength of light could allow them to target tumors of different sizes and locations in the brain.
The mouse trials also found that the treatment reduced the number of cancer cells in the brain and significantly increased the lifespan of the animals - on average three times that of untreated mice. When a course of chemotherapy was added to treatment, the mice lived even longer.
Researchers acknowledge that no matter how promising the study may seem, it is certainly difficult to extrapolate its results to humans. But experts hope to improve the device for use on patients, as another method to combat this deadly form of cancer.[5]
A new type of radiation therapy has begun to be applied, which significantly delays the recurrence of brain cancer
