Abstract
Proton and photon (γ-) radiation is widely used in modern clinical practice for the treatment of malignant tumors of various locations. The relative biological effectiveness (RBE) of accelerated protons is about 1.1, as follows from the results of experimental studies of clonogenic survival of tumor cells in vitro. But however, despite the low RBE of proton radiation, a number of clinical studies have shown a significant increase in relapse-free and overall survival of patients after proton therapy compared with that after standard radiotherapy using photon radiation. The mechanisms, on which the differences recorded in vivo are based, are of significant scientific and practical interest, but have been poorly studied.
期刊介绍：
Cardiometry is an open access biannual electronic journal founded in 2012. It refers to medicine, particularly to cardiology, as well as oncocardiology and allied science of biophysics and medical equipment engineering. We publish mainly high quality original articles, reports, case reports, reviews and lectures in the field of the theory of cardiovascular system functioning, principles of cardiometry, its diagnostic methods, cardiovascular system therapy from the aspect of cardiometry, system and particular approaches to maintaining health, engineering peculiarities in cardiometry developing. The interdisciplinary areas of the journal are: hemodynamics, biophysics, biochemistry, metrology. The target audience of our Journal covers healthcare providers including cardiologists and general practitioners, bioengineers, biophysics, medical equipment, especially cardiology diagnostics device, developers, educators, nurses, healthcare decision-makers, people with cardiovascular diseases, cardiology and engineering universities and schools, state and private clinics. Cardiometry is aimed to provide a wide forum for exchange of information and public discussion on above scientific issues for the mentioned experts.
