Neoadjuvant Concomitant Modulated Electro-hyperthermia in HER2-negative Breast Cancer

Oncotherm EHY-2030 is a non-invasive electromagnetic devices with known anti-tumoral effects. It operates in a precision capacitive coupled impedance matched way, working on a radiofrequency of 13.56 MHz. mEHT exploits various biophysical differences of cancer cells. For example, energy absorption on the membrane rafts is different than those of healthy host cells, and damage-associated molecular patterns (DAMPS) will also occur leading to programmed or immunogenic tumor cell death. mEHT can enhance DNA fragmentation of tumor cells, increase the fraction of cells with low mitochondrial membrane potential, increase the concentration of intracellular Ca2+, increase the Fas, c-Jun N-terminal kinases and MAPK/ERK signaling pathways, increase the expression of pro-apoptotic Bcl-2 family proteins and can up-regulate the expression of genes associated with the molecular function of cell death (EGR1, JUN, and CDKN1A) and silencing others associated with cytoprotective functions.
