Summary
Radiopharmaceuticals aid surgeons in locating endocrine tumors during surgery. Radioactive probes detect concentrated radioactivity in tumor tissue, improving localization, especially in difficult cases.
Area of Science:
- Nuclear medicine
- Surgical oncology
- Endocrinology
Background:
- Primary endocrine tumors present diagnostic and surgical challenges.
- Scintigraphy using radiopharmaceuticals offers a method for tumor visualization.
- Intraoperative detection requires specific radiopharmaceuticals and sensitive probes.
Purpose of the Study:
- To review the utility of radiopharmaceuticals and radioactive probes in intraoperative detection of endocrine tumors.
- To highlight the role of these technologies in challenging surgical cases.
Main Methods:
- Utilizing radiopharmaceuticals like (123I), (125I), (131I)-mIBG, (111In)-pentetreotide, or anti-CEA antibodies.
- Employing intraoperative probes (diode or scintillating crystal based) to detect radioactivity.
- Positioning probes close to tumor tissue to overcome background radioactivity.
Main Results:
- Successful visualization of endocrine tumors via scintigraphy.
- Assistance to surgeons in difficult cases using radioactive probes.
- Promising results reported for pheochromocytomas, thyroid carcinomas, and gastroenteropancreatic tumors.
Conclusions:
- Radiopharmaceuticals and intraoperative probes are valuable tools for endocrine tumor surgery.
- These techniques are particularly useful for reoperation when conventional imaging fails.
- Advancements in probe technology enhance sensitivity and ease of use.
