What is Bor Neutron therapy?
Therapy of neutron Boron capture is a new technique of cancer treatment that scientists hope to become a reliable alternative to surgery, chemotherapy and radiation. The procedure includes injection of cancer tumor with high concentrations of boron isotopes and then subjected to low -intensral beam tumor. When neutrons penetrate Bor atoms, there is a reaction that emits lithium-ion and high-energy alpha particle. The reaction destroys nearby cancer cells, while healthy tissue remains unharmed. The therapy of capturing the boron of neutrons is still in the experimental stages, but could become a support for treatment in several years or decades.
boron isotopes with ten neutrons are ideal for cancer therapy because they are non -radioactive and tend to look for and bind to cancer cells. During the treatment of pine neutron, the concentrated solution of the boron is served by a vein in the arm or neck. Atoms travel in the bloodstream to the tumor site and attach seabnormal cells. Specialists can confirm thatE Boron is isolated to the tumor and is not widespread in healthy tissue with fluorescent X -rays.
As soon as Boron is in place, the tumor shows a large beam emitting neutrons. The beam emits neutrons at a controlled speed and slows them down significantly before they reach the patient. When the isotope Boron lifts the neutron, it enters an unstable, excited state. The alpha particle is quickly issued when the boron atom disintegrates into lithium. Highly charged alpha particles and lithium ion spread over a very short distance, probably the width of a single cancer cell.
High particle energy causes local cells to be smoothed. Cell damage is limited to the tumor because the particles do not spread far enough to achieve the surrounding tissue. In clinical assessments with animals and human volunteers, boron neutron therapy is at least as effective as conventional radiation and chemotherapyin the treatment of isolated brain tumors. The ongoing studies hope to find out whether the procedure can be useful for tumors in other parts of the body.
Mnoho vědců se domnívá, že terapie zachycení neutronů BORON se brzy stane možností léčby prvních výběrů u pacientů s nefunkčními nádory. While chemotherapy and radiation are often successful, they can cause side effects. In addition to cancerous tumors, radiation can affect healthy tissue and chemotherapy causes confusion to defense of the patient's immune system. The therapy of boron capture neutron has the potential to eliminate both side effects. Probíhající výzkum a klinická hodnocení budou pravděpodobně pokračovat několik let, aby se techniku zdokonalovala dříve, než bude zavedena v nemocnicích.
