Suitable Use of Nanostructures in the Treatment of Tumors by the Radiofrequency Ablation Method

Popis výsledku v původním jazyce

Radiofrequency ablation (RFA) is a minimally invasive method, suitable for treatment of irresectable primary and secondary tumors. The principle of this method is to supply electric current to the target?s centre where it causes coagulative necrosis. Electric current, generated by a radiofrequency (rf.) generator, is used for ablation. Electrodes of different shape and dimensions (according to the type of tumor tissue and lesion shape and size) are then used to optimize 3D distribution of electric current in the area to be treated. If tumor centers are of approximately spherical shape, that could be generated by the use of electrodes, then the treatment will be effective. More irregular the tumor shape is, faster the treatment effect decreases. High doses of energy are concentrated in the immediate vicinity of the applicator resulting in heat production. Considerable heat loss occurs as the transfer of thermal energy decreases rapidly with distance. Moreover, the thermal energy transfe
