  • Sunitinib is currently the first line drug therapy for metastasizing renal cell carcinoma (RCC). It has been shown to have a profound effect on tumor angiogenesis leading to modifications of the tumor’s microenvironment. Tumor hypoxia plays an important role in the metastatic potential of a solid tumor and its resistance to any chemotherapy. Therefore, monitoring tumor hypoxia could potentially be used to detect and analyze therapeutic response. The present study utilized Positron-Emission Tomography (PET) to determine changes in tumor oxygenation during and following sunitinib therapy in a mouse RCC tumor model. Uptake of [18F]FAZA tended to decrease during therapy of sunitinib, indicating a decrease in the tumor’s hypoxia. However, after stopping drug therapy in tumor-bearing mice, this effect was reversed and tumor hypoxia was increased. [18F]FAZA could potentially be used to monitor drug response of sunitinib therapy for RCC.
