'Omics'-based imaging in cancer detection and therapy

Area of Science:

• Biomedical Imaging
• Molecular Diagnostics
• Translational Oncology

Background:

• The integration of 'omics' (genomics, proteomics, metabolomics) with imaging is revolutionizing cancer research.
• Gene expression, protein profiles, and metabolite analyses provide crucial molecular insights into cancer.
• These molecular data can guide the development of novel imaging biomarkers and therapeutic strategies.

Purpose of the Study:

• To explore the inter-relationship between omics technologies and medical imaging in cancer.
• To highlight recent advancements in using omics-derived information for cancer diagnosis and therapy.
• To discuss novel strategies for improved cancer detection, assessment, and treatment.

Main Methods:

• Gene expression profiling using microarrays and histochemical assays.
• Proteomics analysis via mass spectrometry (MS) and antibody development for immunoassays and imaging.
• Metabolomics profiling using nuclear magnetic resonance (NMR) spectroscopy and MS, including magnetic resonance spectroscopic imaging (MRSI).

Main Results:

• Antibodies targeting overexpressed proteins enable in vivo imaging and targeted therapy.
• Radiolabeled antibodies and novel tracers facilitate cancer detection via PET and other imaging modalities.
• MRSI combined with MRI enhances cancer assessment, potentially leading to new PET tracers.

Conclusions:

• The convergence of omics and imaging offers powerful tools for advancing cancer diagnosis and therapy.
• Integrating molecular and anatomical information improves the understanding of cancer's location, extent, and aggressiveness.
• This synergistic approach paves the way for more personalized and effective cancer management strategies.
