Abstract

This study aimed to carry out the preclinical studies of [89Zr]Zr-DFO-Bevacizumab. The radiolabeled compound was prepared with radiochemical purity >99% (ITLC), and a specific activity of 74 GBq/g. Cellular studies indicated the great capability of [89Zr]Zr-DFO-Bevacizumab for binding to SKOV3 cell lines. High accumulation was observed in the tumor. The liver and spleen received the highest absorbed dose with 1.12 and 0.72 mGy/MBq, respectively. This radiopharmaceutical can be considered as a suitable PET agent for VEGF-expressing ovarian cancer imaging.
