Background. Androgen deprivation therapy (ADT) in nonmetastatic prostate cancer is unclear. Recent data suggests possible increase in the cardiovascular risks receiving ADT. The aim of the study was to investigate the cardiovascular outcomes in a cohort of Chinese nonmetastatic prostate cancer patients with no previously documented cardiovascular disease. Methods and Results. 745 patients with no previously documented cardiovascular disease and/or diabetes mellitus diagnosed to have nonmetastatic prostate cancer were recruited. Of these, 517 patients received ADT and the remaining 228 did not. After a mean follow-up of 5.3 years, 60 patients developed primary composite endpoint including (1) coronary artery disease, (2) congestive heart failure, and (3) ischemic stroke. Higher proportion of patients on ADT (51 patients, 9.9%) developed composite endpoint compared with those not on ADT (9 patients, 3.9%) with hazard ratio (HR) of 2.06 (95% confidence interval (CI): 1.03-3.24, P = 0.04). Furthermore, Cox regression analysis revealed that only the use of ADT (HR: 2.1, 95% CI: 1.03-4.25, P = 0.04) and hypertension (HR: 2.0, 95% CI: 1.21-3.33, P < 0.01) were independent predictors for primary composite endpoint. Conclusion. ADT in Chinese patients with nonmetastatic prostate cancer with no previously documented cardiovascular disease was associated with subsequent development of cardiovascular events.

Androgen receptor (AR) signaling is a target in prostate cancer therapy and can be treated with non-steroidal anti-androgens (NSAA) including enzalutamide, and apalutamide for patients with advanced disease. Metastatic castration-resistant prostate cancer (mCPRC) develop resistance becomes refractory to therapy limiting patient overall survival. Darolutamide is a novel next-generation androgen receptor-signaling inhibitor that is FDA approved for non-metastatic castration resistant prostate cancer (nmCRPC).

The recent evidences provided in metastatic hormone sensitive prostate cancer (nmHSPC) and in nonmetastatic castration resistant (nmCRPC) introduced the possibility to adopt Androgen Receptor Signaling inhibitor (ARSi) alone (both settings) or with chemotherapy (in mHSPC). In daily clinical practice there are some opening questions regarding the inclusion of next generation imaging, mainly PSMA-PET, how integrate local treatment as radiotherapy, how to select patients or drugs in a multiple-choice scenario, and how to manage patients with comorbidities and polypharmacy. These issues led the Italian Society for Uro-Oncology (SIUrO) to develop a consensus project involving all of the most important Italian scientific societies engaged in the multidisciplinary and multiprofessional management of the disease.

Localized high-risk (HR) prostate cancer (PCa) is a heterogeneous disease whose likelihood of a biochemical recurrence, metastatic progression and cancer-related mortality after initial treatment is higher when compared with patients with low (LR) or intermediate-risk (IR) disease. In the past, neoadjuvant therapy has shown an improvement in postoperative oncological variables but failed to demonstrate any survival advantages. With the promising results from novel treatments in metastatic and non-metastatic castration resistant PCa settings, new evidence has appeared in the literature in the neoadjuvant setting.

Despite treatment, prostate cancer commonly progresses into castration-resistant prostate cancer (CRPC), which remains largely incurable, requiring the development of new interventions. Darolutamide is an orally administered second-generation androgen receptor inhibitor indicated for patients with non-metastatic CRPC or metastatic hormone-sensitive prostate cancer. Here, we evaluated the effect of androgen receptor (AR) inhibition by darolutamide in combination with DNA double-strand-break-inducing targeted radium-223 alpha therapy in vitro and in an intratibial LNCaP xenograft model mimicking prostate cancer metastasized to bone.

The National Cancer Institute (NCI) recognizes the potential of technologies based on the use of nanoparticles (NPs) in revolutionizing clinical approaches to the diagnosis and prognosis of cancer. Recent research suggests that once NPs come into contact with the biological fluid of cancer patients, they are covered by proteins, forming a "protein corona" composed of hundreds of plasma proteins. The concept of a personalized, disease-specific protein corona, demonstrating substantial differences in NP corona profiles between patients with and without cancer, has been introduced.
