Bnct targeting
WebJun 2, 2015 · Boron neutron capture therapy (BNCT) is a promising cancer therapy modality that utilizes the nuclear capture reaction of epithermal neutrons by boron-10 resulting in a localized nuclear fission reaction and subsequent cell death. Since cellular destruction is limited to approximately the diameter of a single cell, primarily only cells in … WebOne advantage of BNCT over conventional radiotherapy is that its clinical efficacy depends largely on the high accumulation of 10 B in tumor cells with minimal uptake of normal …

WebMar 4, 2024 · As the keypoint of BNCT, all boron delivery agents currently in clinical use are beset by insufficient tumor uptake, especially in the tumor nucleus, which limits the … WebThrough biological targeting, BNCT offers an approach to overcoming radiation resistance in some types of cancer, as well as a potential cure for locally recurrent solid tumors after maximal conventional therapies.
WebMar 14, 2024 · BNCT as a biologic target therapy is different with an external radiotherapy as an anatomic target therapy. It means that normal organs are safe even though patients’ intrinsic or extrinsic movement because the selectivity of cancer cells with high 10 B concentration is the main mechanism of cell death [ 8 ]. WebIntroduction. Boron neutron capture therapy (BNCT) is a binary radiotherapeutic modality that combines tumor-targeting boron (10 B) drugs and thermal neutron radiation.10 B absorbs thermal neutrons (< 0.5 eV) and results in a nuclear reaction that generates high linear energy transfer (LET) particles, alpha particles (4 He) and lithium (7 Li) nuclei. 1 …
WebMar 4, 2024 · BNCT combines the advantages of biological target and heavy ion radiotherapy. It achieves accurate and efficient attack on tumor cells through generating an obvious boron concentration gradient between tumor cells and normal cells, thereby minimizing the toxic and side effects on normal tissues [6, 7]. BNCT is considered to be … WebBoron neutron capture therapy (BNCT) is a radiotherapy utilizing the neutron capture and nuclear fission reaction of 10B taken up into tumor cells.
