Over the past decade, there has been a continued interest in the development of Boron Neutron Capture Therapy (BNCT) as a potential treatment for cancerous tumours and especially certain brain tumours. In this method, advantage is taken of the nuclear properties of certain elements such as boron. A special boron carrier drug, designed to be selectively taken up by the cancer cells, is administe...

BACKGROUND Boron neutron capture therapy (BNCT) is based on the nuclear reaction that occurs when boron-10 is irradiated with low-energy thermal neutrons to yield high linear energy transfer alpha particles and recoiling lithium-7 nuclei. Clinical interest in BNCT has focused primarily on the treatment of high-grade gliomas and either cutaneous primaries or cerebral metastases of melanoma, most...

Boron neutron capture therapy (BNCT) is an effective clinical method in cancer treatment based on fission reactions and nuclear capturing. In this method, use of the best boron-containing agents for boron therapy and boron delivery agent for transfer to the infectious site are the key points for  efficienct treatment. Our research indicated that calcium fructoborate(CF) was the best compound as...

Introduction Electron linear accelerator (LINAC) can be used for neutron production in Boron Neutron Capture Therapy (BNCT). BNCT is an external radiotherapeutic method for the treatment of some cancers. In this study, Varian 2300 C/D LINAC was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for BNCT. Materials and Methods Photoneutron sources w...

Boron Neutron Capture Therapy (BNCT) is known to be a promising and new cancer therapy which can kill tumor cells suppressing damage to normal tissues. Recently, accelerator based neutron sources (ABNS) for BNCT are under development especially in Japan. For characterization of the neutron field, we carried out the series study concerning thermal/epi-thermal neutron spectrometry especially for ...

BACKGROUND Glioma stem cells in the quiescent state are resistant to clinical radiation therapy. An almost inevitable glioma recurrence is due to the persistence of these cells. The high linear energy transfer associated with boron neutron capture therapy (BNCT) could kill quiescent and proliferative cells. METHODS The present study aimed to evaluate the effects of BNCT on glioma stem/progeni...

Boron neutron capture therapy (BNCT) involves administration of a boron compound followed by neutron irradiation of the target organ. The boron atom captures a neutron, which results in the release of densely ionizing helium and lithium ions that are highly damaging and usually lethal to cells within their combined track length of approximately 12 microns. Prior to Phase I clinical trials for p...

Herein we propose and validate the hamster cheek pouch model of oral cancer for boron neutron capture therapy (BNCT) studies. This model serves to explore new applications of the technique, study the biology and radiobiology of BNCT, and assess the uptake of boron compounds and response of tumor, precancerous tissue, and clinically relevant normal tissues. These issues are central to evaluating...

  Background : Performing successful BNCT experiments needs a suitable neutron source. Important factors of the neutron beam are flux and energy that are very important in the selection of neutron source. In most centers that use this method for treatment, reactor is a neutron source, which according to characteristics of the reactor appropriated neutrons are very high. High cost of constructin...

25 Laurentia Gales 258 Șos.Fundeni, 2nd District, Bucharest, Romania e-mail: [email protected] Abstract. Boron neutron capture theory (BNCT) is a binary therapy applied in malignant tumours, resistant to other treatment methods, namely chemotherapy and radiotherapy. One of the main components is Bor-10, a stable isotope that can be inserted in the tumour cells by using specific transpor...
