Hyperthermia treatment for solid tumors is a long-used, but poorly accepted method in clinical use. Modulated electro-hyperthermia (mEHT, trade name: oncothermia®) changes the paradigm, introduces a novel, cellularly selective and immunogenic cell-ruination. The mEHT method produces tumor-vaccination, presenting the unharmed genetic information of...
Article
Lifetime analyses frequently apply a parametric functional description from measured data of the Kaplan-Meier non-parametric estimate (KM) of the survival probability. The cumulative Weibull distribution function (WF) is the primary choice to parametrize the KM. but some others (e.g. Gompertz, logistic functions) are also widely applied. We show th...

Heating as a medical intervention in cancer treatment is an ancient approach, but effective deep heating techniques are lacking in modern practice. The use of electromagnetic interactions has enabled the development of more reliable local-regional hyperthermia (LRHT) techniques whole-body hyperthermia (WBH) techniques. Contrary to the relatively si...
Chapter
We studied the homeostatic equilibrium of the healthy organism. The homeostasis is controlled by oppositely effective physiologic feedback signal-pairs in various time-scales. We show that the entropy of every signal in this state is identical and constant: SE=1.8. The controlling physiological signals fluctuate around their average values. The flu...

Hyperthermia in oncology needs a definite dose which fixes well the clinical protocols. The temperature is far not a dose, it is mass independent. The half of the mass has the same temperature in equilibrium, so the basic criteria of the dose mass-dependence are lost. The energy could be a great option for dosing, (like it is in radiation therapies...

Dissipation is essential for the evolution of a quantum-damped oscillator. It is responsible for the decay of quantum states, the broadening of the spectral line, and the shifting the resonance frequency. This has been a persistent challenge for a long time since dissipation causes difficulties in the quantization of the damped oscillator [1, 2, 3]...

In "hypethermia", the procedure of raising the temperature of a part, or the whole body, up to 42 degrees C to kill cancer cells for a defined period of time is applied alone or as an adjunctive with various established cancer treatment modalities such as radiotherapy and chemotherapy. However, "hyperthermia" is not generally accepted as convention...

Hyperthermia method was “reborn” with the electromagnetic applications a century ago when deep heating became a realistic goal. The lack of its wide application is that the locally targeted volume has physiological consequences; the systemic control of the human body tries to compensate the active deviation from the homeostatic equilibrium. Clues f...

Oncothermia (OTM) is an electro-hyperthermia modality, a long time (since 1989) applied method, [1], used successfully in human oncology [2]. OTM changes the paradigm of hyperthermia by targeted microscopic heat-liberation at the membrane of the malignant cells. This method creates inhomogeneous heating, and the microscopic temperature greatly diff...
