RT Journal Article SR Electronic T1 Vascular Changes in Cancer Treatment—Seeing Is Believing JF Cancer Research JO Cancer Res FD American Association for Cancer Research SP 3461 OP 3462 DO 10.1158/0008-5472.CAN-20-2361 VO 80 IS 17 A1 Tomaszewski, Michal R. YR 2020 UL http://cancerres.aacrjournals.org/content/80/17/3461.abstract AB Understanding the effects of novel cancer drugs on the tumor microenvironment will be crucial for their successful use in patients. In this issue of Cancer Research, Ghosh and colleagues discuss the effect of two promising heme-targeting agents on the vascular network in mouse models of lung cancer, utilizing emerging optoacoustic imaging approaches. The findings demonstrating significant, dynamic modulation of tumor hypoxia with the heme-targeting drug treatments create important opportunities for image-guided combination therapy.See related article by Ghosh et al., p. 3542
