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...

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...

PURPOSE To develop a procedure for the optimum patient positioning and immobilization during boron neutron capture therapy (BNCT) of glioblastoma multiforme (GBM) at the Brookhaven medical research reactor (BMRR). METHODS A replica of the treatment room in the BMRR was constructed to simulate patient position. A unique feature is a transparent opening in wall to simulate the location of the b...

BACKGROUND/AIM The tumor suppressor gene p53 is mutated in glioblastoma. We studied the relationship between the p53 gene and the biological effects of boron neutron capture therapy (BNCT). MATERIALS AND METHODS The human glioblastoma cells; A172, expressing wild-type p53, and T98G, with mutant p53, were irradiated by the Kyoto University Research Reactor (KUR). The biological effects after n...

BACKGROUND Boron neutron capture therapy (BNCT) is a selective radiotherapy that is dependent on the accumulation of ¹⁰B compound in tumors. Low-intensity ultrasound produces a transient pore on cell membranes, sonoporation, which enables extracellular materials to enter cells. The effect of sonoporation on BNCT was examined in oral squamous cell carcinoma (SCC) xenografts in nude mice. MATER...

The purpose of this clinical trial was to evaluate the utility of boron neutron capture therapy (BNCT) using epithermal neutrons for cases of recurrent cancer in the oral cavity, which are not indicated for a conventional treatment modality. We enrolled four patients with local recurrence or metastasis to the regional lymph nodes after completion of initial treatments, including surgery, chemot...

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 ...

Radiation therapy is the therapeutic modality in which high energy radiations are used to kill tumor cells [1]. Conventional radiation therapy is a whole body radiation process resulting in numerous side effects, highlighting the need to identify alternative targeted therapy [1]. BNCT is a targeted therapy in which cancer cells accumulate boron and are subsequently bombarded with neutrons [2]. ...
