Characterizing the Tumor Response to Treatment With Combretastatin A4 Phosphate

Conclusions: The present study shows that those areas of a tumor that survive treatment with CA4P are affected by CA4P exposure, though only transiently. The decrease in perfusion could negatively affect therapies utilizing the combination of CA4P and conventional anticancer agents by decreasing drug delivery and tissue oxygenation. These findings suggest that the timing of CA4P treatments when used in conjunction with conventional anticancer therapies should be considered carefully.
