Vascular Normalization: Study Examines How Antiangiogenesis Therapies Work
| The first 10% of the full text of this article appears below. |
It is a widely held belief that antiangiogenic therapy eradicates tumor vasculature, thus depriving the tumor of oxygen and nutrients necessary for survival. But this may not be the complete story. A new study published in December in Cancer Cell suggests that antiangiogenic therapy may also "normalize" the tumor vasculature for a short period of time, thereby providing a window of opportunity for improved drug delivery and enhanced sensitivity to radiation treatment.
Clinical trials have suggested a benefit to giving antiangiogenic agents in combination with other
