Intratumoral Distribution

Purpose. We aimed to clearly visualize heterogeneous distribution of hypoxia-inducible factor 1α(HIF) activity in tumor tissuesin vivo.Methods. We synthesized of125I-IPOS, a125I labeled chimeric protein probe, that would visualize HIF activity. The biodistribution of125I-IPOS in FM3A tumor-bearing mice was evaluated. Then, the intratumoral localization of this probe was observed by autoradiography, and it was compared with histopathological findings. The distribution of125I-IPOS in tumors was imaged by a small animal SPECT/CT scanner. The obtainedin vivoSPECT-CT fusion images were compared withex vivoimages of excised tumors. Fusion imaging with MRI was also examined.Results.125I-IPOS well accumulated in FM3A tumors. The intratumoral distribution of125I-IPOS by autoradiography was quite heterogeneous, and it partially overlapped with that of pimonidazole. High-resolution SPECT-CT fusion images successfully demonstrated the heterogeneity of125I-IPOS distribution inside tumors. SPECT-MRI fusion images could give more detailed information about the intratumoral distribution of125I-IPOS.Conclusion. High-resolution SPECT images successfully demonstrated heterogeneous intratumoral distribution of125I-IPOS. SPECT-CT fusion images, more favorably SPECT-MRI fusion images, would be useful to understand the features of heterogeneous intratumoral expression of HIF activityin vivo.
