BNCT (Boron Neutron Capture Therapy) is a treatment method that utilizes the nuclear reaction between neutrons and boron to selectively destroy cancer cells while causing minimal damage to normal tissues. It is anticipated to be effective for primary cancers, solitary tumors, and cancers that have spread to various organs, as well as metastatic and refractory cancers. Furthermore, BNCT can be performed even after conventional radiation therapy. When used in combination with other therapeutic approaches, BNCT has the potential to further enhance treatment efficacy and is expected to be effective for recurrent cancers. Unlike surgery, BNCT does not involve extensive incisions, which is expected to significantly improve the patient's quality of life.

Irradiation Range (Treatment Range): In conventional radiotherapy, the irradiation range is determined based on the extent of tumor infiltration and surrounding normal tissues. In contrast, BNCT allows for a relatively broad irradiation range because normal cells within the range do not absorb boron and thus do not undergo nuclear fission reactions upon neutron irradiation, resulting in almost no damage to normal tissues.

Key Features of BNCT (Boron Neutron Capture Therapy)

1. Reduced Damage to Normal Cells: Causes significantly less damage compared to standard radiotherapy.
2. Applicable for Recurrence: Can be performed on patients who have experienced recurrence after conventional radiotherapy.
3. Broad Efficacy: Anticipated to be effective for invasive, multiple, and radioresistant cancers.
4. Short Treatment Course: Typically involves only 1 to 2 irradiation sessions, with each session lasting approximately 30 to 60 minutes.
5. Predictable Efficacy: Treatment outcomes can be predicted through PET imaging.
