MPM is difficult to treat because it easily disseminates. Boron neutron capture therapy (BNCT) is a radiotherapy in which cancer cells that selectively take up 10Boron-containing compounds are destroyed, and normal cells are uninjured. Hyaluronan (HA) is a ligand of cluster of differentiation 44 (CD44), that is expressed on MPM cells. Materials and Methods: In order to enhance BNCT for MPM tumors, we developed a novel HA-containing 10B (sodium borocaptate: BSH) formulation (HA-BND-S). We examined the efficacy of HA-BND-S using MPM cells and a mouse MPM model. Results: HA-BND-S preferentially bound MPM cells dose-dependently, and increased the cytotoxicity of BNCT compared to BSH in vitro. HA-BND-S administration significantly increased the survival of MPM tumor-bearing mice compared to BSH at the same 10B dosage in BNCT. Conclusion: Modifying BSH with HA is a promising strategy for enhancing the efficacy of BNCT for therapy of MPM.
