Abstract:
Clinical trials using antiangiogenic drugs revealed their potential against cancer. Unfortunately, a large percentage of patients does not yet benefit from this therapeutic approach highlighting the need of diagnostic tools to non-invasively evaluate and monitor response to therapy. It would also allow to predict which kind of patient will likely benefit of antiangiogenic therapy. Reasons for treatment failure might be due to a low expression of the drug targets or prevalence of other pathways. Molecular imaging has been therefore explored as a diagnostic technique of choice. Since the vascular endothelial growth factor (VEGF/VEGFR) pathway is the main responsible of tumor angiogenesis, several new drugs targeting either the soluble ligand or its receptor to inhibit signaling leading to tumor regression could be involved. Up today, it is difficult to determine VEGF or VEGFR local levels and their non-invasive measurement in tumors might give insight into the available target for VEGF/VEGFR-dependent antiangiogenic therapies, allowing therapy decision making and monitoring of response.
Insights
Antiangiogenic drugs show cancer potential, but patient response varies. Molecular imaging can non-invasively assess vascular endothelial growth factor (VEGF/VEGFR) levels, aiding treatment decisions and monitoring for targeted cancer therapy.
Area of Science:
- Oncology
- Molecular Imaging
- Biomedical Engineering
Background:
- Antiangiogenic drugs offer cancer treatment potential but lack efficacy in many patients.
- Predicting and monitoring patient response to antiangiogenic therapy is crucial for treatment success.
- Treatment failure may stem from low drug target expression or alternative signaling pathways.
Purpose of the Study:
- To explore molecular imaging as a diagnostic tool for evaluating antiangiogenic therapy response.
- To enable non-invasive measurement of vascular endothelial growth factor (VEGF/VEGFR) levels in tumors.
- To aid in patient selection and monitoring for VEGF/VEGFR-targeted therapies.
Main Methods:
- Review of clinical trials involving antiangiogenic drugs.
- Exploration of molecular imaging techniques for diagnostic applications.
- Focus on the vascular endothelial growth factor (VEGF/VEGFR) pathway in tumor angiogenesis.
Main Results:
- Molecular imaging presents a promising approach for non-invasive assessment of antiangiogenic therapy.
- Measuring local VEGF/VEGFR levels could identify patients likely to benefit from targeted therapies.
- Non-invasive monitoring can guide treatment decisions and track therapeutic response.
Conclusions:
- Molecular imaging can provide critical insights into VEGF/VEGFR pathway activity.
- This approach supports personalized medicine by enabling tailored antiangiogenic treatment strategies.
- Further development of molecular imaging is essential for optimizing cancer therapy.
