Radiotracer Innovations in Breast Cancer Imaging: A Review of Recent Progress

Area of Science:

• Nuclear Medicine
• Oncology
• Radiochemistry

Background:

• Radiotracers are essential tools in nuclear imaging for breast cancer management.
• ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) is a widely used radiotracer for detecting metabolic activity in tumors.

Purpose of the Study:

• To review the role of radiotracers in breast cancer detection, staging, and treatment monitoring.
• To explore emerging radiotracers targeting specific molecular pathways for personalized medicine.

Main Methods:

• Review of current literature on radiotracer applications in breast cancer imaging.
• Discussion of established techniques like PET and PEM using ¹⁸F-FDG.
• Exploration of novel radiotracers targeting receptors such as estrogen receptors and HER2.

Main Results:

• ¹⁸F-FDG PET/PEM effectively identifies primary tumors, metastases, and assesses treatment response by highlighting glucose metabolism.
• Targeted radiotracers provide molecular insights into tumor characteristics, enabling tailored treatment strategies.
• Radiotracer integration enhances early detection and therapeutic efficacy monitoring.

Conclusions:

• Radiotracers significantly improve breast cancer management, from diagnosis to treatment evaluation.
• Development of advanced radiotracers promises to further personalize breast cancer care and advance precision medicine.
• Continued research in radiotracer development is vital for improving patient outcomes in breast cancer.
