Magnetic fluid hyperthermia therapy for malignant brain tumors—an ethical discussion

This paper describes the worldwide first nanoparticle-based therapy against brain tumors termed magnetic fluid hyperthermia (MFH) or Nano-Cancer therapy, which now is under investigation in a phase II study. The preliminary results show evidence of a local effectiveness and with only minor to moderate therapy-associated side effects. The evaluation, according to the principles of medical ethics (autonomy, beneficence, nonmaleficence, justice), supports the further development of the MFH therapy.From the Clinical EditorThis paper describes the worlwide first nanoparticle-based therapy of brain tumors through local hyperthermia now under investigation in a phase II study.
