Zaragoza, Spain
A generator of high-voltage pulses to destroy tumors without using chemotherapy has been developed by researchers from the Spanish universities of Zaragoza and Pompeu Fabra (Barcelona).
with this system of irreversible electroporation may destroy solid tumors more quickly, less toxic and invasive than chemotherapy and radiotherapy, explained Thursday a statement from the University of Zaragoza.
this phenomenon is the death of cells when these unable to repair damage the high electric fields cause in their cell wall.
irreversible electroporation has important benefits for the patient against other more aggressive treatments because it is neither heat nor uses drugs, but could also applied in combination with standard medical therapies to achieve greater effectiveness and improve recovery times.
This new technology biomedical application has been published in its latest issue in the journal IEEE Journal of Emerging and Selected Topics in Power Electronics.
the patent has attracted interest from several companies, which will advance the irreversible electroporation as an effective tool in the fight against cancer.
at the moment, said the university center, the generator, which can apply voltages up to 12 kV peak to peak and currents up to 400 amps, has been successfully tested in studies ” in vivo “and has demonstrated its ability to destroy large volumes of tissue.
Oscar Lucia, researcher of the Group of Power Electronics and Microelectronics, said, bought with chemotherapy, this system it is more localized and less harmful, because it involves thermal heating unlike radiotherapy or radio frequency and, therefore, recovery is faster and less sequelae.
