Whole-Body Hyperthermia in Oncology: Renaissance in the Immunotherapy Era?

Abstract

A short introduction to the use of whole-body hyperthermia (WBH) in oncology is provided. The main focus is on fever-range whole-body hyperthermia (FRWBH), since various preclinical studies have shown promising results using this approach. However, FRWBH has not been comprehensively investigated in clinical oncology trials. Having provided an overview on the methods to induce WBH, we will summarize preclinical and clinical data on the mode of action of FRWBH. The latter treatment positively affects the tumor micromilieu, especially by decreasing tumor hypoxia. It has the potential to enhance tumor-directed immune reactions and has proven anti-depressive and potential analgesic effects in patients without cancer. These pleiotropic effects align with good tolerability and high acceptability by patients. Given the available evidence, we argue that FRWBH should be investigated as an adjunct to modern cancer treatments in controlled clinical trials.

Bessere Abwehr durch Thermotherapie jenseits natürlicher Quellen?

“…In den Wirkungsweisen manchmal schwer unterscheidbar bzw. überlappend sind direkte zytotoxische Wirkungen, insbesondere durch erhöhte Verfügbarkeit von Sauerstoff im Tumorgewebe, von immunologisch günstigen Veränderungen des den Tumor umgebenden Mikromilieus [4].…”
