Introduction

In 1972, an experimental study on boron neutron capture therapy (BNCT) for malignant melanoma was initiated by Mishima and his colleagues (Kobe University group). They first proposed employing BNCT for malignant melanomas utilizing the specific melanin synthesis activity of melanoma cells. For that purpose, 10B-paraboronophenylalanine (BPA) was reevaluated by his group. After 15 years of basic research, this team started the first clinical trial of cutaneous melanoma BNCT using BPA in 1987 [1–12]. Thanks to improvement in boron delivery agents and lowenergy neutron beam technology, several BNCT clinical trials for melanoma were started in the world: at the Massachusetts Institute of Technology in 1994 for cutaneous melanoma and in 1996 for intracerebral melanoma (Harvard/MIT group) [13–15], at the high flux reactor in Petten in 2002 for brain metastases of melanoma (Petten/Essen group) [16, 17], at RA-6 reactor in Argentina in 2003 for cutaneous melanoma (Ar
