Background. Modulated electrohyperthermia (mEHT) is a noninvasive technique for targeted tumor treatment. Method. HT29 human colorectal carcinoma cell line xenografted to both femoral regions of BalbC/nu/nu mice was treated with a single shot OTM treatment. Histomorphologic, immunohistochemical analysis TUNEL assay, and R&D Apoptosis array were performed on tissue samples. Results. mEHT caused a selective tumor demolition. An upregulation of TRAIL-R2 and FAS was observed. Cleaved caspase-3 positive cells appear at the tumor periphery. Cytochrome c and AIF release was observed in line with massive TUNEL positivity. Conclusion. In HT29 colorectal cancer xenograft, mEHT caused massive caspase independent cell death.
