Iranian researchers increased efficiency of cancer heat therapy by laboratorial and analytical simulation


TEHRAN (INIC)- Iranian researchers made efforts to increase efficiency of cancer heat therapy process by laboratorial and analytical simulating of the process at the same time.


Heating cancer tissues is one of the methods to eliminate cancer tumors.


Hyperthermia generally means an increase in the body temperature in an unnatural manner. High temperature of body usually results in a sickness such as fever or thermal shock. However, controlled hyperthermia is sometimes used in the treatment of illness, specially cancers.  


The most important objective of this research was to accurately determine optimum parameters of the heating process to cure cancer tumors by using super paramagnetic nanoparticles. Hyperthermia process has been studied in this research both in laboratorial scale and through solving equations and programming.


This research studied and simulated heat therapy process in a precise manner. It also determined the exact dosage of nanoparticles, time and intensity of magnetic field to eliminate cancer tumor at given dimensions. Iron-based super paramagnetic nanoparticles with average diameter of 20 nm have been used in heat therapy process. The process was simulated on a dead animal tissue, and a stream of artificial blood circulation was used to make the behavior of the dead tissue close to that of a living tissue.


In addition, thermal profile was analyzed and studied in order to eliminate a tumor at a radius of 3 cm by using computer simulation and by solving mathematical equations for the tissues.


Results of the research have been published in Journal of Mechanical Science and Technology, vol. 30, issue 3, 2016, pp. 1459-1469.
