Laser flashes for cancer research
15. März 2022
Irradiation with fast protons is a more effective and less invasive cancer treatment than X-rays. However, modern proton therapy requires large particle accelerators, which has experts investigating alternative accelerator concepts, such as laser systems to accelerate protons. Such systems are deployed in preclinical studies to pave the way for optimal radiation therapy. A research team has now successfully tested irradiation with laser protons on animals.
How the immune system responds to tissue damage can aid cancer spread
25. Februar 2022
Researchers have uncovered how a process involved in the regeneration of tissue damaged by radiation can aid the spread of cancer.
Light therapy fast-tracks healing of skin damage from cancer radiation therapy
28. Januar 2022
Light therapy may accelerate the healing of skin damage from radiation therapy by up to 50%, according to a recent study.
Stem cell discoveries hold potential to improve cancer treatment
26. Januar 2022
Recent discoveries by stem cell scientists may help make cancer treatment more efficient and shorten the time it takes for people to recover from radiation and chemotherapy.
Boosting T cells improves survival in mice with glioblastoma
19. Januar 2022
A new study shows that treatment with an immune-boosting protein called interleukin 7 (IL-7) in combination with radiation improves survival in mice with glioblastoma. The study in mice suggests promise for a phase 1/2 clinical trial that is investigating a long-acting type of IL-7 in patients with glioblastoma.
Microorganism sheds new light on cancer resistance
24. Dezember 2021
Scientists describe T. adhaerens‘ unusual behavior, including its capacity to repair its DNA even after significant radiation damage and to extrude injured cells, which later die. The findings advance scientific investigations of natural cancer-suppression mechanisms across life. Insights gleaned from these evolutionary adaptations may find their way into new and more effective therapies for this leading killer.
Strategy to overcome tumors’ resistance to immunotherapy generates promising clinical trial results
24. November 2021
Immune checkpoint inhibitors strengthen the immune response against cancer cells, but the medications are ineffective against certain tumors. Results from a new clinical trial indicate that adding radiation may overcome this resistance to immune checkpoint inhibitors.
New technique may lead to safer stem cell transplants
12. November 2021
Studying mice, researchers have developed a method of stem cell transplantation that does not require radiation or chemotherapy. Instead, the strategy takes an immunotherapeutic approach, combining the targeted elimination of blood-forming stem cells in the bone marrow with immune-modulating drugs to prevent the immune system from rejecting the new donor stem cells.
Arginine, an inexpensive oral drug, could enhance radiation therapy for cancer
8. November 2021
Treatment with arginine, one of the amino-acid building blocks of proteins, enhanced the effectiveness of radiation therapy in cancer patients with brain metastases, in a proof-of-concept, randomized clinical trial.
New test to diagnose aggressive childhood brain tumors
3. November 2021
Researchers have developed a new test to more easily diagnose medulloblastoma, the most common malignant childhood brain tumor. The test — which can distinguish between extremely high-risk medulloblastoma cases that need radiation therapy from those that are lower-risk and do not need radiation — could help pave the way for personalized treatment options for children suffering from the disease. It relies on an antibody-based technique called immunohistochemistry which is widely available in clinical laboratories around the world.
Targeting cancer at the nanoscale
22. Oktober 2021
Researchers fabricate gold nanoparticles with a rapidly decaying radioisotope that can be internalized by cancer cells. Because the radiation remains strongly localized, high doses can be administered without concern for side effects. This research may lead to safer and more effective treatments for many types of cancer.
Targeting a rare secondary cancer in children
29. September 2021
Known as pediatric radiation-induced high-grade gliomas (RIGs), this specific type of brain tumor is caused by cranial radiation therapy for other cancers, most often brain cancers. They account for nearly 4% of all childhood brain tumor deaths, but there have not been many studies on RIGs and how to treat them.
Radiation therapy reprograms heart muscle cells to younger state
25. September 2021
New research suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.
