Clinical Results of Boron Neutron Capture Therapy

The early American clinical trials of Boron Neutron Capture Therapy (hereinafter BNCT) for malignant brain tumors at Brookhaven National Laboratory (BNL) and at the Massachusetts Institute of Technology (MIT) ended in 1961 without having achieved the objectives of the therapy. The aim had been a highly selective destruction of tumor cells while preserving normal organ which harbors the tumor. The last series, 17 cases treated at the MIT Research Reactor, yielded an average survival of 5.7 months. Contrary to expectation, the survival was short and damage to the normal brain (including vascular damage and coagulation necrosis of the brain in the worst case) was found upon autopsy of these patients. BNCT was totally discontinued after 1961. However, it is important to note that the early clinical experience obtained between 1951 and 1961 and described in the literature of that period contributed to my revised therapy conducted after 1968 in Japan, although I had never taken part in the earlier American effort.
