Summary
Cancer is a diverse group of diseases characterized by uncontrolled cell growth and the ability to invade or metastasize to other parts of the body. The wide range of cancer types stems from differences in the cells of origin and the molecular abnormalities driving their progression. Urological malignancies, such as prostate and kidney tumors, pose significant health challenges.Prostate cancer is the second most common cancer in males worldwide and a leading cause of cancer-related deaths in many regions. The androgen receptor (AR) signaling pathway plays a crucial role in prostate cancer growth and progression. The AR is a nuclear hormone receptor that regulates the transcription of genes involved in cell proliferation and survival by binding to androgens such as testosterone and dihydrotestosterone (DHT) in the nucleus. Aberrant AR signalingresulting from overexpression, genetic mutations, or persistent activationdrives prostate cancer progression and contributes to resistance against conventional therapies.For localized renal cell carcinoma (RCC), robotic radical nephrectomy remains the primary curative treatment. However, approximately 40% of RCC patients experience tumor recurrence after surgical resection. Systemic treatment options include small-molecule tyrosine kinase inhibitors (TKIs), cytokines, and monoclonal antibodies, including checkpoint inhibitors, which have been evaluated as both first-line and second-line therapies. Despite advancements, drug resistance remains a major obstacle to effective RCC treatment. Even with the use of vascular endothelial growth factor (VEGF) inhibitors, mammalian target of rapamycin (mTOR) inhibitors, and RAF kinase inhibitors, resistance continues to limit clinical success.This special issue aims to provide a comprehensive understanding of the molecular mechanisms underlying prostate cancer and RCC, highlight recent discoveries, and explore potential avenues for personalized treatment strategies.
