Theranostics, a combination of therapy and diagnostics, is a field of personalized medicine involving the use of the same or similar radiopharmaceutical agents for the diagnosis and treatment of patients. Prostate-specific membrane antigen (PSMA) is a promising theranostic target for the treatment of prostate cancers. Diagnostic PSMA radiopharmaceuticals are currently used for staging and diagnosis of prostate cancers, and imaging can predict response to therapeutic PSMA radiopharmaceuticals. While mainly used in the setting of metastatic, castrate-resistant disease, clinical trials are investigating the use of PSMA-based therapy at earlier stages, including in hormone-sensitive or hormone-naïve prostate cancers, and in oligometastatic prostate cancers. This review explores the use of PSMA as a theranostic target and investigates the potential use of PSMA in earlier stage disease, including hormone-sensitive metastatic prostate cancer, and oligometastatic prostate cancer.

Oral Cyclophosphamide for Patients With Metastatic Castration-Resistant Prostate Cancer in a Scenario of Limited Health Care Resources.
JCO Glob Oncol

Genitourinary Medical Oncology Service, Instituto do Câncer do Estado de São Paulo (ICESP), University of São Paulo, São Paulo, Brazil.
Purpose: Prior noncontemporary studies showed that oral cyclophosphamide is an active treatment of metastatic castration-resistant prostate cancer (mCRPC). However, cyclophosphamide is currently underutilized in routine clinical practice given the lack of survival benefit and the emergence of more effective treatments.
Methods: We retrospectively reviewed our institutional database to identify patients with mCRPC treated with cyclophosphamide.
Predicting the risk of bone metastases in patients with newly diagnosed prostate cancer - Development and validation of a nomogram model.
PLoS One

Institute of Translational Medicine, Medical College, Yangzhou University, Yangzhou, Jiangsu, PR. China.
Objectives: The aim of this study was to develop and validate a nomogram model that predicts the risk of bone metastasis (BM) in a prostate cancer (PCa) population.
Methods: We retrospectively collected and analyzed the clinical data of patients with pathologic diagnosis of PCa from January 1, 2013 to December 31, 2022 in two hospitals in Yangzhou, China. Patients from the Affiliated Hospital of Yangzhou University were divided into a training set and patients from the Affiliated Clinical College of Traditional Chinese Medicine of Yangzhou University were divided into a validation set.
Incisional PSMA PET/CT-positive recurrences in prostate cancer- is there an implication on clinical care?
Clin Exp Metastasis

Martini-Klinik Prostate Cancer Center, University Hospital Hamburg-Eppendorf, Hamburg, Germany.
Oligorecurrent prostate cancer (PCa) can be treated with metastasis-directed therapy (MDT), which may be performed using radioguided surgery (RGS) as an experimental approach. These procedures have shown promising outcomes, largely due to the high lesion detection rate of positron emission tomography/computed tomography (PET/CT). We present a case series of patients who underwent RGS following robot-assisted radical prostatectomy (RARP).

Background And Objective: MicroRNAs (miRNAs) are implicated in cancer by exerting roles in tumor growth, metastasis, and even drug resistance. The general trends of miRNA research in diverse cancers are not fully understood. In this work, miRNA-related research in colorectal cancer, prostate cancer, leukemia, and brain tumors was analyzed in search of key research trends with clinical potential.

Background: Metastatic castration-resistant prostate cancer (mCRPC) treatment is advancing yet Nordic, real-world evidence for its use is scarce. In this population-based cohort study, we describe characteristics of patients with mCRPC, and their treatment patterns and survival outcomes in Finland.
Methods: Incident patients with mCRPC diagnosed during 2013-2021 were identified from data lakes in two large and representative, Finnish hospital districts, and linked to data on drug purchases and causes of death from national registries.
