Abstract:
Precision medicine, basing treatment approaches on patient traits and specific molecular features of disease processes, has an important role in the management of patients with breast cancer as targeted therapies continue to improve. PET imaging offers noninvasive information that is complementary to traditional tissue biomarkers, including information about tumor burden, tumor metabolism, receptor status, and proliferation. Several PET agents that image breast cancer receptors can visually demonstrate the extent and heterogeneity of receptor-positive disease and help predict which tumors are likely to respond to targeted treatments. This review presents applications of PET imaging in the targeted treatment of breast cancer.
Insights
Precision medicine improves breast cancer treatment by tailoring therapies to individual patients. Positron emission tomography (PET) imaging provides crucial noninvasive insights into tumor characteristics, guiding targeted treatment selection.
Area of Science:

- Medical Imaging
- Pharmacology
Background:
- Precision medicine is revolutionizing breast cancer management through targeted therapies.
- Positron emission tomography (PET) imaging offers noninvasive data complementary to traditional biomarkers.
- PET provides insights into tumor burden, metabolism, receptor status, and proliferation.
Purpose of the Study:
- To review the applications of PET imaging in the targeted treatment of breast cancer.
- To highlight how PET aids in understanding tumor heterogeneity and predicting treatment response.
Main Methods:
- Review of current literature on PET imaging agents for breast cancer.
- Analysis of how PET visualizes receptor status and disease extent.
- Discussion of PET's role in predicting response to targeted therapies.
Main Results:
- PET imaging agents can visualize receptor-positive breast cancer extent and heterogeneity.
- PET data complements traditional biomarkers, offering a comprehensive view of the disease.
- PET can help predict which tumors are likely to respond to specific targeted treatments.
Conclusions:
- PET imaging is a valuable tool in the precision medicine approach to breast cancer.
- Its ability to assess tumor characteristics noninvasively supports personalized treatment strategies.
- PET imaging enhances the selection and monitoring of targeted therapies for breast cancer patients.
