    Abstract Erdheim-Chester disease (ECD) is a rare clonal histiocytic process that is characterized by a foamy (xanthomatous) proliferation often associated with Touton giant cells. The diagnosis is often challenging and not exclusively a histologic diagnosis, as it requires correlation with unique clinical, radiographic, and recently described molecular findings. Activating mutations involving the MAPK pathway including BRAF, ARAF, N/KRAS, and MEK are recurrent in the disease. However, it is increasingly being described that mutations associated with clonal hematopoiesis are also found in bone marrow specimens of patients with ECD, as well as higher frequency of overt concomitant myeloid malignancy including acute myeloid leukemia, myeloproliferative neoplasms, myelodysplastic syndromes, and mixed myeloproliferative neoplasms/myelodysplastic syndromes. Herein, we report a unique case of a patient presenting with BRAFV600E-positive ECD with peripheral blood findings consistent with a concurrent myeloid malignancy featuring co-occurrence of NRAS and IDH2 mutations.

    Abstract The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 62-year-old man with a 45 pack per year tobacco-smoking history presented with painless gross hematuria in the fall of 2015 and was ultimately diagnosed with muscle-invasive urothelial bladder cancer. He received four cycles of cisplatin-based neoadjuvant chemotherapy followed by radical cystectomy with pelvic lymph node dissection, which disclosed residual high-grade muscle-invasive urothelial cancer extending to the perivesical fat and involving two of 20 pelvic lymph nodes (pT3N2). Six months later, surveillance imaging identified new retroperitoneal lymphadenopathy and a large right pelvic mass with possible rectal wall invasion consistent with locally recurrent and metastatic urothelial cancer. Although feeling generally well, he reported having had progressive constipation, pelvic pressure, and narrow-caliber stools for 2 months. He was seen in consultation for management of recurrent bladder cancer.

    Abstract Cancers of the genitourinary (GU) tract are common malignancies in both men and women and are a major source of morbidity and mortality. Immune checkpoint inhibitors (ICI) targeting CTLA-4, PD-1 or PD-L1 have provided clinical benefit, particularly in renal cell and urothelial carcinoma, and have been incorporated into standard of care treatment in both localized and metastatic settings. However, a large fraction of patients do not derive benefit. Identification of patient and tumor-derived factors which associate with response have led to insights into mechanisms of response and resistance to ICI. Herein, we review current approvals and clinical development of ICI in GU malignancies and discuss exploratory biomarkers which aid in personalized treatment selection.

    Abstract Purpose of review: Since 2016, five new programmed cell death protein 1/ligand 1 (PD-1/L1) checkpoint inhibitors have been approved for metastatic urothelial carcinoma. This review will summarize the data supporting the widespread use of these agents and highlight areas of ongoing clinical development.
    Recent findings: PD-1/L1 axis inhibition has demonstrated clear superiority to chemotherapy for the treatment of metastatic urothelial cancer in the second-line setting. A multitude of ongoing studies are investigating the feasibility and efficacy of incorporating established and novel immunotherapies into earlier lines of therapy, including non-metastatic muscle-invasive bladder cancer and even non-muscle-invasive disease. Early-phase clinical trials have begun to explore the safety and activity of novel immune-oncology combinations across a range of clinical settings. Immunotherapy has a clearly defined role in the treatment of metastatic urothelial cancer both in the platinum-refractory setting and in the first-line cisplatin-ineligible setting. Ongoing clinical trials will dictate how to best incorporate immunotherapy into earlier lines of therapy and define the safety and activity of novel immunotherapy agents and combinations.

    Abstract Chemotherapy is no longer the only viable option for patients with locally advanced or metastatic urothelial carcinoma. Immunotherapy, as checkpoint inhibition, has received United States Food and Drug Administration approval in the preceding several years, both in the second-line and first-line for cisplatin-ineligible patients. Those who respond often do so durably; however, response rates in the first line are 23% to 24%, and are lower in the second line. With a focus on urothelial carcinoma, this review discusses the tumor microenvironment and its negative influence on anti-tumor immunity, as well as measures to counteract immune suppression or evasion. The review then describes a range of current clinical trials implementing these measures in the form of programmed death-combination therapy, specifically in advanced bladder and urothelial cancers.

    Abstract Taxanes have had a profound impact on the management of genitourinary tumors. In the perioperative and metastatic setting in bladder cancer, taxanes such as paclitaxel have an established role in combination chemotherapy strategies to improve survival. In metastatic prostate cancer, docetaxel was the only treatment, until recently, shown to improve survival after the development of castration resistance. More recently, cabazitaxel, a synthetic taxane derivative, is an effective option after docetaxel failure. In advanced testicular cancer, taxanes play an important role in the management of relapsed disease with the ability to still achieve cure. This chapter will focus on the development and current role of taxanes in the treatment of genitourinary cancers including bladder, prostate, and testis cancers as well as the status of novel agents currently under investigation.

    Abstract Introduction: Until recently, there has been little advancement in the management of invasive and metastatic urothelial cancer in over 30 years, and outcomes with cisplatin-based chemotherapy remain unchanged. Inhibitors targeting PD-1 signaling on cytotoxic T-cells have revolutionized bladder cancer therapy leading to durable responses. Atezolizumab is an engineered humanized anti-PD-L1 monoclonal antibody that inhibits PD-L1 binding to PD-1 and B7.1, enhancing immune-mediated tumor killing and is currently approved as second-line treatment after failure of platinum-based chemotherapy as well as first-line in cisplatin-ineligible patients. Areas covered: This article summarizes all reported phase I, II and III clinical trials that assessed the safety and efficacy of atezolizumab in the treatment of locally advanced and metastatic urothelial carcinoma. Expert commentary: Treatment with atezolizumab showed durable response and a toxicity profile that appears favorable to cytotoxic chemotherapy historically in the treatment of metastatic urothelial cancer among individuals who had progressed after prior platinum-based therapy and among those ineligible for treatment with first-line cisplatin. PD-L1 expression and tumor mutation load associate with response, however further research is needed to identify additional markers to improve prediction of response to atezolizumab.
