Results of a human toxicity pilot study are reported. Eleven patients with heavily pre-treated advanced cancer were enrolled in the study with different schedules of time exposure to static magnetic fields, amplitude modulated by extremely low frequency. The aim was to assess the safety of a magnetic field treatment for patients with cancer.
Aspartate aminotransferase and alanine aminotransferase elevation (grade 2 toxicity) in one patient and microscopic urinary abnormalities in five patients were the only negative effects revealed. The data support the possibility that the human exposure to magnetic field with specific physical characteristics is associated with a favorable safety profile and good tolerability. Further investigations need to confirm the observations.
