Collecting duct carcinoma was described over 30 years ago as a renal tumor, based in the medullary collecting system, with tubulopapillary morphology, prominent infiltrative growth, and stromal desmoplasia. While diagnostic workup has always emphasized exclusion of upper tract urothelial carcinoma and metastatic adenocarcinoma to the kidney, the molecular era of renal cell carcinoma classification has enabled recognition of and provided tools for diagnosis of new entities in this morphologic differential. In this review, we consider these developments, with emphasis on renal medullary carcinoma, closely related renal cell carcinoma, unclassified with medullary phenotype, and fumarate hydratase-deficient renal cell carcinoma...

Objectives: To assess the performance of urine markers determined in urine samples from the bladder compared to samples collected from the upper urinary tract (UUT) for diagnosis of UUT urothelial carcinoma (UC). Patients and Methods: The study comprised 758 urine samples either collected from the bladder ( n = 373) or UUT ( n = 385). All patients underwent urethrocystoscopy and UUT imaging or ureterorenoscopy. Cytology, fluorescence in situ hybridization (FISH), immunocytology (uCyt+), and nuclear matrix protein 22 (NMP22) were performed...

Neoadjuvant chemotherapy improves survival in patients with muscle-invasive bladder cancer. However, a significant proportion of patients are ineligible for cisplatin owing to renal impairment or other medical comorbidities. The introduction of anti-programmed cell death protein 1/programmed death-ligand 1(PD1/PD-L1) checkpoint inhibitors has redefined the therapeutic landscape for platinum-resistant urothelial cancers; their clinical efficacy and favorable toxicity render these agents attractive therapeutic options either as monotherapy or in combination with other agents in earlier disease states, including muscle-invasive disease...

A select group of patients with upper tract urothelial carcinoma (UTUC) may meet indications for endoscopic management. Strategies for disease management are provided, based on a comprehensive review of the data using PubMed and Medline databases and marrying this with our experience with endoscopic management of UTUC. Endoscopic management of UTUC via retrograde or antegrade approaches is a viable treatment option for appropriately selected patients with low-risk UTUC, including those with low-grade, low-volume, and solitary tumors...

There are currently no reported randomized trials that characterize the staging or therapeutic benefit of performing a lymph node dissection in either bladder cancer or upper tract urothelial carcinoma. Several unanswered questions remain in this domain focused on the indications and patient selection for pelvic lymph node dissection, extent of dissection, its impact on outcome, and potential risks. However, the results of observational studies suggest that the burden of metastasis is high in both diseases when muscle invasive and performing a lymphadenectomy can provide prognostic information and yield therapeutic benefit...

Upper tract urothelial carcinoma is a rare malignancy that has an abundance of surgical treatment options, including open, laparoscopic, robotic, and endoscopic approaches. As advances in technology allow for shorter, less morbid operations, the variation in care of this uncommon disease has raised concerns about compromising oncologic principles. Many institutions have described their experience with promising results; however, there is a paucity of high-quality data that supports the use of robotic surgery as a new gold standard...

Radical cystectomy with bilateral pelvic lymph node dissection is the standard of care for patients with clinically localized muscle-invasive bladder cancer. Survival after radical cystectomy is associated with final pathologic staging. Survival decreases with increasing pT stage because of the presence of occult micrometastases, indicating the need for systemic chemotherapy. Systemic chemotherapy is delivered as either neoadjuvant therapy preoperatively, or as adjuvant therapy postoperatively. This article reviews the evidence for neoadjuvant and adjuvant chemotherapy for the treatment of muscle-invasive bladder and upper tract urothelial cancer and offers recommendations based on these data and recently updated clinical guidelines...

Upper tract urothelial cancer (UTUC) arises from the urothelial lining of the urinary tract. UTUC spreads in several different ways including direct invasion, lymphatic spread, and hematogeneous metastases. Regional lymph nodes are commonly the initial site of metastasis, followed by the liver, lung, and bone. Brain metastasis is uncommon in patients with urothelial carcinoma. Here, we report an uncommon case of kidney urothelial carcinoma with brain metastasis in a 55-year-old woman presenting with dysarthria with right side limb weakness...

Epithelial-mesenchymal transition (EMT) is a process which epithelial cells gain mesenchymal phenotype such as motility and invasiveness. We investigated the role of EMT in upper urinary tract urothelial carcinoma (UTUC). The patient cohort included 93 cases of UTUC treated with radical nephroureterectomy. Tissue microarrays were constructed from formalin-fixed paraffin-embedded tissue blocks. Immunohistochemical staining was performed for E-cadherin, vimentin, and smooth muscle actin to evaluate the EMT status...

A 64-year old woman was admitted to the hospital for severe abdominal pain and distension after gardening and chopping wood the day before. She had a medical history of superficial transitional cell carcinoma (TCC) of the urinary bladder and a laparoscopic nefro-ureterectomy for an invasive TCC of the upper urothelial tract in 2012. Clinical examination showed an acute abdomen. Laboratory analysis revealed a plasma creatinine level of 4,23 mg/dl. Computed tomography (CT) imaging of the abdomen showed hypodense free intraperitoneal fluid, suspicious for ascites...

BACKGROUND: Upper tract urothelial carcinoma (UTUC) accounts for approximately 5% of all urothelial cancers. Because of similarities in morphology and histology between UTUC and urothelial carcinoma of the bladder, most treatment guidelines used for UTUC are extrapolated from the urothelial bladder carcinoma setting. With the emergence of new treatment modalities, such as immunotherapy, UTUC-specific prognostic and predictive models are needed. PATIENTS AND METHODS: A retrospective study of 454 UTUC patients who received surgery at Cleveland Clinic (1995-2014) was conducted...
