The gold standard of medical therapy for advanced prostate cancer is based on the use of androgen-receptor inhibitors and taxane-based chemotherapy. Several new agents, such as enzalutamide, apalutamide, darolutamide and abiraterone, are now approved and currently used in clinical practice.We present a review of the literature on the current state of the art on the use of androgen receptors inhibitors for the treatment of castration-resistant prostate cancer. We also provide an update on recent significant progress and ongoing clinical trials, and discuss the underlying cancer biology of castration resistance.The advent of second-generation androgen receptor inhibitors has radically changed the therapeutic landscape of advanced prostate cancer. Novel strategies targeting the androgenic signaling pathway are being evaluated in order to overcome resistance mechanisms, to optimize the sequence of drugs currently available and to develop new combinational approaches to improve survival outcomes of advanced prostate cancer patients. New clinical trials, predictive biomarkers research, and real-world experience may further improve clinical outcomes and guide clinicians in the decision-making process.

Introduction: Despite significant advances in the treatment of metastatic urothelial carcinoma, including the advent of immune checkpoint inhibitors, this disease is still challenging to treat and associated poor outcomes remain. Genomic characterization of advanced-stage urothelial carcinoma is widening the field of potential treatments due to the identification of novel biologic drivers. Areas covered: In this review, we explore the role of PARP, HER-2, and mTOR inhibitors in the therapeutic scenario of advanced urothelial carcinoma, as these pathways are frequently altered in urothelial carcinoma. We report ongoing clinical trials involving these agents, either in monotherapy or in combination with other compounds, highlighting the dynamic scenario of metastatic urothelial carcinoma treatment. Expert opinion: Several challenges need to be faced in the development of new potential therapeutic strategies, such as inter/intratumoral heterogeneity and the lack of validated biomarkers.

The aim of this paper was to perform a narrative review of the literature on the available approaches in the treatment of two emerging subpopulations of metastatic renal cell carcinoma (mRCC) patients: the oligometastatic disease (less than 5 metastasis) and the oligoprogressive disease, defined as worsening in maximum 3-5 sites while all other tumor sites are controlled by systemic therapy.We explore all possible approaches in these settings of patients: the role of local therapies, considering both surgical metastasectomy and/or ablative techniques, the efficacy of systemic therapies and the rationale behind active surveillance. We also discuss ongoing clinical trials in these settings.Two different strategies are emerging as the most promising for the approach to the oligometastatic/oligoprogressive mRCC patient: (1) the use of immunocheckpoint inhibitors following metastasectomy; (2) the use of stereotactic radiotherapy alone or combined with immunotherapy for oligometastatic disease. The lack of validated biomarkers of response in these mRCC patient subpopulations is opening the way to the employment of novel technologies. Among them, the use of artificial intelligence seems to be the candidate to contribute to precision oncology in patients with mRCC.
