Abstract
The anti-hypoxia-A2-Adenosinergic immunotherapies of cancer emerged as the only available now approach to enable the tumor rejection in those progressing cancer patients that are refractory to all other current treatments. Several different classes of drugs are offered to inhibit the Hypoxia-HIF-1alpha-mediated and extracellular adenosine-A2A adenosine receptor-mediated immunosuppressive signaling in tumor microenvironment. It is suggested that the most promising treatments must include the blockade of cAMP-elevating A2A adenosine receptors and the elimination of hypoxia in tumors by oxygenation agents and hyperoxic breathing. The observations in ongoing clinical trials support this conclusion. Copyright © 2020. Published by Elsevier Ltd.
