Abstract
Prostate cancer, ranking among the most prevalent malignancies in males worldwide, is undergoing a significant evolution in therapeutic paradigms from conventional approaches to precision medicine, with recent advances in targeted therapies offering novel strategic insights. This review delineates the molecular foundations of prostate carcinogenesis, elucidating pivotal domains including genetic mutations, hormonal regulation, tumor microenvironment dynamics, cell cycle dysregulation, epigenetic modifications, and tumor heterogeneity. Furthermore, we evaluate the clinical translation of targeted strategies such as AR signaling axis inhibition, PI3K/AKT/mTOR pathway modulation, DNA damage repair machinery exploitation, prostate-specific membrane antigen -directed interventions, and combinatorial immunotherapy. Concurrent challenges-AR-driven heterogeneity, adaptive drug resistance mechanisms, spliceosomal vulnerabilities, and scarcity of selective molecular targets-are critically analyzed. Notwithstanding these obstacles, targeted therapies exhibit considerable potential to enhance therapeutic efficacy while mitigating systemic toxicities, paving the way for more personalized and precision-oriented oncologic care. By underscoring the imperative to decode prostate cancer's molecular architecture, this work outlines future research priorities and advances a robust scientific framework for innovation in therapeutic development.
