Prof. Dr. Thomas Vogel, University of Frankfurt, treated 44 men who were suffering from prostate cancer with Galvano-therapy (that is, ECT) in the context of a study. Two needle electrodes were introduced to the tumour area under magnetic resonance imagery and direct current applied. Each patient received 3 treatments with a week between each one. Subsequently, follow-up investigations by MRT and determination of the PSA (prostate-specific antigen) values after 3, 6 and 12 months.
Result: The treatments were tolerated by all the patients without serious side-effects. After 12 months, one patient’s tumour was completely removed, in 18 patients it was reduced, in 23 the growth had stopped and in 2 the illness continued to progress. Overall, the tumour size had reduced on average by 42% and the PSA value had dropped by 66%.
Commentary: The type of treatment in this study was not optimal because prostate cancer often exceed the capsule (that is, there is cancer tissue outside of the actual prostate) If this is treated with needle electrodes, there is a danger of not destroying the whole cancer ulcer which leads as a result to relapses. Apart from that enough treatments have to be carried out until all the tumour tissue is completely depolarised (which can be seen from the changes in current strength and electrical resistance), so possibly more than 3 treatments. Overall, better results are achieved when prostate cancer is treated with flat electrodes placed in a particular form on the body’s outer surface around the tumour area. With this technique there is no need for the expensive MRT imaging. In spite of these limitations, the results of the study are remarkable.

New tissue-conservative procedure for prostate cancer
FRANKFURT / MAIN (cin). For patients with prostate carcinoma there now is a new tissue-conservative treatment: the MRI-guided galvano-therapy. In a study, radiologists from the University of Frankfurt have now proven the safety and efficacy of this therapy for local control of prostate carcinomas. Moreover, the prostate-specific antigene (PSA) was reduced. (...)
