Tumor hypoxia is considered to be relevant for several aspects of tumor pathophysiology, for acquired treatment resistance, and tumor progression (e. g., in cancers of the uterine cervix). Therefore, there is a demand for simple and universally applicable methods allowing the estimation of oxygenation status in patient material obtained during pretherapeutic diagnostic procedures (biopsies) or surgical treatment. Protein members of the transcriptional response to hypoxia expressed in tumor tissue, e. g., hypoxia-inducible factor-1alpha (HIF-1alpha), glucose transporter-1 (GLUT-1) and carbonic anhydrase IX (CA IX) are currently being discussed as "endogenous hypoxia markers".
