A novel concept of treatment of diffuse or multiple pleural tumors by boron neutron capture therapy (BNCT)

Two patients, one with malignant pleural mesothelioma and one with a malignant short spindle cell tumor, received boron neutron capture therapy (BNCT). In each case, the tumors regressed or remained stable in size for 3–6 months following BNCT. No acute or late adverse events higher than grade 2 were observed.
