Non-invasive detection of lymph node metastasis is an extremely important medical procedure mandatory for the determination of the most relevant clinical intervention for individual cancer patients. Nonetheless, lymph node biopsy remains the current gold-standard for this procedure, which is highly invasive. To address this urgent clinical issue, this study has explored the potential utility of Fe-phytate complex as a novel magnetic resonance imaging (MRI) contrast agent for non-invasive metastatic lymph node imaging. The proposed parent compound, phytate, has already proven to be clinical applications in the form of 99Tc-phytate for the mapping of various types of cancer patients, and MRI is a well-known, safe imaging modality free of ionizing radiation. The efficacy of the Fe-phytate complex in non-invasive metastatic lymph node imaging was tested in a mouse model of melanoma for lymph node metastases. The isothermal titration calorimeter (ITC) analyses for the thermodynamic property of Fe-phytate clearly suggested that the proposed contrast agent is biologically safe and clinically applicable for the detection of metastatic lymph node in cancer patients. All MRI experiments were performed on a 9.4 T Bruker animal MR scanner. For histopathological analyses, tissue sections were examined with hematoxylin and eosin (H&E) staining, analyzed for tumor metastases of lymph nodes with fluorescence microscopy, and stained with Prussian blue to examine the biodistribution of Fe-phytate particles. The results strongly suggested that Fe-phytate complex can detect metastatic lymph node by MRI in the mice model of melanoma, that the potential applicability of the proposed contrast agent to different cancer models.
