    Abstract Introduction: Metastatic castrate resistant prostate cancer (mCPRC) remains an aggressive form of prostate cancer that no longer responds to traditional hormonal treatment alone. Despite the advent of novel anti-androgen medications, many patients continue to progress, and as a result, there is a growing need for additional treatment options.

    Abstract The use of immunotherapy has revolutionized the management of patients with locally advanced, unresectable, and metastatic urothelial carcinoma (UC); however, platinum-based chemotherapy remains a therapeutic cornerstone both in localized muscle-invasive and advanced UC. There is still no predictive molecular biomarker with clinical utility to help guide treatment and select patients most likely to derive benefit from a particular therapeutic modality or regimen. However, recent research has further characterized the inherent biology and immunology landscapes of UC leading to the development of potential biomarkers and therapeutic targets that could be used upon further validation. Emerging interrogation of The Cancer Genome Atlas (TCGA) and other molecular profiling datasets has led to the identification of distinct molecular subtypes with diverse clinical behaviors with potential sensitivity to various therapies. It has also led to the discovery of multiple frequently altered genes and proteins that could lead to perturbation of intracellular signaling pathways and of the dynamic interactions between tumor cells, their "microenvironment", and the host "macro-environment". The advent of molecular profiling and deeper next-generation sequencing has the potential to change biomarker and "real time" drug sensitivity assessment, introducing and testing the premise of "precision oncology" and personalized medicine. Within this review, we summarize emerging biomarkers that may predict response to cisplatin-based chemotherapy, immunotherapy, emerging targeted therapies, and promising combination strategies. We also highlight a few examples of 'precision medicine' trials aiming to improve outcomes in UC. Since our review is not exhaustive we strongly recommend the readers to follow the continuously changing literature in the very interesting and dynamic field of UC.

    Abstract Urethral adenocarcinoma of males is a rare disease with limited prospective data to define optimal treatment. Surgical excision remains the primary treatment for early-stage disease. Multimodality therapy with a combination of chemotherapy, radiation, or surgery has been explored in patients with locally advanced disease. We present the case of a 45-year-old-man with a locally recurrent urethral adenocarcinoma after initial surgical resection managed successfully with combined weekly cisplatinum and radiation therapy.

    Abstract Prostate cancer represents one of the leading causes of cancer-related mortality in the United States and the most common cancer among men. Treatment paradigms for the management of advanced stages of prostate cancer have continued to evolve in recent years. These advancements in the therapeutic landscape of metastatic prostate cancer and diagnostic imaging modalities have fundamentally changed the treatment of patients with prostate cancer. In this review article we provide a primer for radiologists highlighting the most recent developments in treatment options and imaging techniques utilized in the modern oncologic management of metastatic prostate cancer. We will examine current therapy options and associated toxicities with an emphasis on relevant imaging findings commonly encountered by radiologists. We also summarize the role of modalities including CT, MRI, PET, bone scintigraphy, and PET in the diagnosis and follow-up of patients with metastatic prostate cancer.

    Abstract Immunotherapy has recently catapulted to the forefront of treatments for patients with solid tumors. Given its inherent immunogenic properties, renal cell carcinoma (RCC) has historically responded to immunotherapy and remains primed for further development. Although immunotherapy with high-dose interleukin 2 was a primary treatment for advanced RCC (aRCC), recent discoveries of key molecular and immunological alterations have led to the FDA-approval of nivolumab, an antiprogrammed cell death inhibitor, which has demonstrated an overall survival in patients with previously treated aRCC. However, despite recent therapeutic advances, aRCC remains an incurable disease for most patients. In this review, we assess the current landscape and future developments of immunotherapy in aRCC.

    Abstract Purpose: Circulating tumor DNA (ctDNA) detection in blood has emerged as a prognostic and predictive biomarker demonstrating improved assessment of treatment response in patients receiving immune checkpoint inhibitors (ICIs). Here, we performed a pilot study to support the role of ctDNA for longitudinal treatment response monitoring in patients with advanced genitourinary (GU) malignancies receiving ICIs.
    Materials and methods: Patients with histologically confirmed advanced GU malignancies were prospectively enrolled. All eligible patients received ICI treatment for at least 12 weeks, followed by serial collection of blood samples every 6-8 weeks and conventional scans approximately every 12 weeks until disease progression. ctDNA analysis was performed using Signatera, a tumor-informed multiplex-polymerase chain reaction next-generation sequencing assay. Overall, the objective response rate (ORR) was reported and its association with ctDNA status was evaluated. Concordance rate between ctDNA dynamics and conventional imaging was also assessed.
    Results: ctDNA analysis was performed on 98 banked plasma samples from 20 patients (15 renal, four urothelial, and one prostate). The median follow-up from the time of initiation of ICI to progressive disease (PD) or data cutoff was 67.7 weeks (range, 19.6-169.6). The ORR was 70% (14/20). Eight patients ultimately developed PD. The overall concordance between ctDNA dynamics and radiographic response was observed in 83% (15/18) of patients. Among the three patients with discordant results, two developed CNS metastases and one progressed with extracranial systemic disease while ctDNA remained undetectable.
    Conclusion: In this pilot study, longitudinal ctDNA analysis for monitoring response to ICI in patients with advanced GU tumors was feasible. Larger prospective studies are warranted to validate the utility of ctDNA as an ICI response monitoring tool in patients with advanced GU malignancies.

    Abstract Background Mammalian target of rapamycin (mTOR) pathway and angiogenesis through vascular endothelial growth factor (VEGF) have been shown to play important roles in prostate cancer progression. Preclinical data in prostate cancer has suggested the potential additive effect dual inhibition of VEGF and mTOR pathways. In this phase I/II trial we assessed the safety and efficacy of bevacizumab in combination with temsirolimus for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC). Methods In the phase I portion, eligible patients received temsirolimus (20 mg or 25 mg IV weekly) in combination with a fixed dose of IV bevacizumab (10 mg/kg every 2 weeks). The primary endpoint for the phase II portion was objective response measured by either PSA or RECIST criteria. Exploratory endpoints included changes in circulating tumor cells (CTC) and their correlation with PSA response to treatment. Results Twenty-one patients, median age 64 (53-82), with pre-treatment PSA of 205.3 (11.1-1801.0), previously treated with a median of 2 (0-5) lines of therapy for mCRPC received the combination of temsirolimus weekly at 20 mg (n = 4) or 25 mg (n = 17) with bevacizumab 10 mg/kg every 2 weeks (n = 21). Median time to progression was 2.6 months (95% CI, 1.2-3.9) and the median best PSA change from baseline to 12 weeks was a 32% increase (-40-632%) which met the predefined futility rule and led to early termination of the study. Nine patients (43%) had ≥ grade 3 toxicity that included fatigue (24%), anorexia (10%), nausea/vomiting (5%) and lymphopenia (5%). In exploratory analysis, a decrease in CTC levels was observed in 9 out of 11 patients. No association between PSA levels and CTC levels was detected. Conclusions The combination of temsirolimus and bevacizumab showed limited clinical activity in mCRPC patients previously treated with chemotherapy and was associated with significant adverse events (AEs). Transient decrease in CTC levels was independent from PSA response. NCT01083368.
