Summary
Dual-target radiopharmaceuticals offer improved efficacy for metastatic castration-resistant prostate cancer (mCRPC). This approach enhances specificity and overcomes challenges with single-target therapies for better patient outcomes.
Area of Science:
- Oncology
- Radiopharmaceutical Therapy
- Molecular Imaging
Background:
- Prostate cancer (PCa) poses a significant global health burden, with metastatic castration-resistant PCa (mCRPC) lacking curative treatments.
- Current single-target radiopharmaceuticals show limitations due to tumor heterogeneity and variable biomarker expression.
- Novel therapeutic strategies are urgently needed to improve survival rates for mCRPC patients.
Purpose of the Study:
- To review advancements in dual-target radiopharmaceuticals for prostate cancer.
- To highlight the potential of these agents in theranostics and personalized medicine.
- To discuss the benefits of dual-targeting over single-targeting approaches.
Main Methods:
- Exploration of recent literature on heterobivalent metal-based radiopharmaceuticals for PCa.
- Analysis of various biomarkers being investigated for dual-targeting strategies.
- Discussion of the advantages of dual-target agents in overcoming limitations of current therapies.
Main Results:
- Dual-target radiopharmaceuticals demonstrate increased therapeutic specificity and efficacy compared to single-target agents.
- They offer improved tumor visualization by addressing variable receptor expression across lesions.
- Several promising targets, including PSMA, GRP receptor, and integrin αvβ3, are being explored.
Conclusions:
- Dual-target radiopharmaceuticals represent a significant advancement in the theranostic management of prostate cancer.
- This approach holds promise for more comprehensive imaging and effective treatment, particularly for mCRPC.
- Further development in this area is crucial for personalized medicine and improved patient survival.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
