Abstract: We reviewed 10B concentration kinetics in the blood and tumors in human patients administered with BPA. The 10B concentration in the blood peaked at the end of intravenous infusion of BPA, followed by a biphasic-decreasing curve with half-lives for the first and second components of the curve being 0.7–3.7 and 7.2–12.0 h, respectively. The mean tumor-to-blood (T/B) ratio obtained from resected tumor samples was 3.40 ± 0.83 for melanoma and the ratio ranged from 1.4 to 4.7 for glioblastoma.
