Prostate cancer is the most common cancer among men and the fifth leading cause of cancer-related death among men worldwide. Gastrin-releasing peptide receptor (GRPR) is an important complementary target of prostate specific membrane antigen (PSMA) and a key target for prostate cancer diagnosis and treatment. Radionuclide labeled bombesin (BBN) analogues can accurately target overexpressed GRPR in tumor cells, thus providing early diagnosis and treatment of prostate cancer. In this review, we focus on the studies of 99Tc m, 111In, 68Ga, 64Cu, 18F, and 177Lu nuclide-labeled BBN analogues for diagnosis and peptide receptor radionuclide therapy.
