Molecular imaging and theranostic approaches in pheochromocytoma and paraganglioma

Area of Science:

• Oncology
• Nuclear Medicine
• Endocrinology

Background:

• Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors originating from neural crest cells.
• These tumors often overexpress specific molecular targets, making them amenable to targeted therapies.
• Current treatment for metastatic PPGLs remains challenging, necessitating novel therapeutic strategies.

Purpose of the Study:

• To explore the potential of radiopharmaceuticals for imaging PPGLs.
• To evaluate the evolving role of somatostatin-based theranostics in managing metastatic PPGLs.

Main Methods:

• Review of current literature on PPGLs, their molecular targets, and imaging techniques.
• Analysis of emerging theranostic approaches utilizing somatostatin receptor agonists and antagonists.

Main Results:

• PPGLs exhibit overexpression of targets suitable for radiopharmaceutical detection.
• Theranostic strategies employing somatostatin agonists and antagonists are demonstrating significant advancements.
• These agents show promise for both diagnosis and targeted therapy in PPGL patients.

Conclusions:

• PPGLs are prime candidates for advanced imaging and theranostic interventions.
• Somatostatin-based theranostics represent a significant progression in the therapeutic armamentarium for metastatic PPGLs.
• Further research and clinical application of these targeted approaches are warranted.
