BACKGROUND: The standard treatment for metastatic renal cancer is based on vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTor) inhibitors. Compared to other advanced tumors, the treatment of renal cancer is highly affected by impaired renal function; therefore, patients with severe renal insufficiency, including patients on hemodialysis, are generally excluded from clinical trials. CASE REPORT: In the present manuscript we present the case of a renal cancer patient who underwent bilateral nephrectomy and received two lines of treatment...

OBJECTIVE: The requirement for and extent of lymphadenectomy in endometrial cancer is still controversial. Clinicopathological prognostic factors could be helpful to predict lymph node involvement and avoid therefore unnecessary lymphadenectomy. The aim of this study was to investigate which factors can predict lymph node involvement and how lymph node metastases are distributed in the pelvic and para-aortic regions. METHODS: This retrospective analysis was performed by analyzing data from patients with endometrial cancer treated with standard surgery and lymphadenectomy at the Department of Gynecology and Obstetrics of the University Hospital Ulm in 2000 to 2013...

Purpose The aim of this work was to investigate the predictive factors for bladder cancer recurrence survival (BCRS) in patients with upper-tract urothelial carcinoma (UTUC). Methods We selected patients with UTUC who underwent segmental ureterectomy (Su) or nephroureterectomy (Nu) from 2004 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with a history of intravesical therapy for bladder cancer and bladder cancer prior to the diagnosis of UTUC were excluded. We used Kaplan-Meier analysis, log-rank tests, and Cox proportional hazards model to compare overall survival, cancer-specific survival, and BCRS...

In the United States, the estimated number of new cases of renal cell carcinoma (RCC) is approximately 65,000 case with about 15,000 deaths in the year of 2018 (Siegel et al. in CA Cancer J Clin 68(1):7, 2018). RCC as an immunogenic malignancy is supported by many theories and facts which include tumor richness of lymphocytes infiltrate, the occurrence of spontaneous tumor regression, and the proved effect of traditional immunotherapy (Finke et al. in J Immunother 11(1):1-11, 1992), all these factors support the potential therapeutic effect of the novel immunotherapeutic agents in RCC...

INTRODUCTION: eGFR-categories are used to predict functional outcome after partial nephrectomy (PN); no study categorized patients according to preoperative renal scan (RS) data. Aim of the study was to evaluate if stratification of patients according to RS is a reliable method to predict minor/major loss of renal function after PN. MATERIALS AND METHODS: We considered patients who underwent PN and RS pre-/post-PN for T1 tumor in our Institution (2007-2017). Demographics, perioperative and specifically functional data were analysed...

NR3C2 has previously been described as a tumor suppressor gene in several cancers; however the prognostic significance and biological function of NR3C2 in patients with non-metastatic clear cell renal cell carcinoma (ccRCC) remain largely unclear. The prognostic value of NR3C2 expression was evaluated using data from The Cancer Genome Atlas (TCGA) and 181 patients with non-metastatic ccRCC undergoing nephrectomy in our center. Predictive nomograms were generated and identified independent prognosticators to assess ccRCC patient overall survival (OS) and progression free survival (PFS) at 1, 5, and 8 years...

PURPOSE: To determine if segmental ureterectomy (SU) could be chosen for wider oncological indications than low-risk ureteral carcinoma, given the difficulties in accurate preoperative risk stratification determination and kidney-sparing needs for successive therapy. METHODS: Data from ureteral carcinoma patients who underwent open SU or laparoscopic radical nephroureterectomy (RNU) between 2011 and 2016 were retrospectively reviewed. Kaplan-Meier survival analysis and Cox regression model with patients' baseline characteristics (age, bladder cancer history, hydronephrosis), procedure type, and tumor characteristics (site, size, pathological features) as covariates were used to evaluate oncological outcomes...

PURPOSE: There is a lack of reporting of the bladder cuff pathology in the literature and ongoing debate regarding the role of bladder cuff excision (BCE) in the prognosis in patients with upper tract urothelial carcinoma (UTUC). We aimed to know the risk factors, the survival, and the clinical course of such pathology. MATERIALS AND METHODS: The study was retrospective, from 1983-2013 on 305 patients who had diagnosed with UTUC. Patients were managed by radical open/ laparoscopic nephroureterectomy with bladder cuff excision...

G1/G2 variants in the Apolipoprotein L1 (APOL1) gene are associated with end-stage renal disease (ESRD) in people with African ancestry. Plasma biomarkers may have utility for risk stratification in APOL1 high-risk individuals of African ancestry. To evaluate this, we measured tumor necrosis factor receptor 1/2 (TNFR1/2) and kidney injury molecule-1 (KIM1) in baseline plasma specimens from individuals of African ancestry with high-risk APOL1 genotype. Biomarker association with a composite renal outcome of ESRD or 40% sustained decline in estimated glomerular filtration rate (eGFR) was then determined and then assessed as improvement in area under curve...

Background: Metastatic dissemination of solid tumors is often initiated by reactivation of an embryonic development program, epithelial-to-mesenchymal-transition (EMT). EMT has been associated with acquiring invasiveness and resistance to conventional therapies. However, the precise role of EMT during renal cell carcinoma is still debatable and is under investigation. In this context, our study is designed to evaluate the role of cyclosporine (CsA) and transforming growth factor-β (TGFβ) administration in inducing EMT-like state in renal carcinoma cells...

BACKGROUND: Among community-dwelling older adults, frailty is associated with heightened markers of inflammation and subsequent mortality. Although frailty is common among ESRD patients, the role of frailty and markers of inflammation in this population remains unclear. We quantified these associations in patients on the kidney transplant (KT) waitlist and tested whether frailty and/or markers of inflammation improve waitlist mortality risk prediction. METHODS: We studied 1,975 ESRD patients on the KT waitlist (11/1/09-2/28/17) in a multi-center cohort study of frailty...

BACKGROUND: Renal angiomyolipoma (AML) is a common benign tumor of the kidney. The main complication of AML is retroperitoneal hemorrhage caused by AML rupture, which can be severe and life threatening. The risk of AML rupture used to be determined by tumor size. However, these criteria have been challenged by series of clinical studies and case reports, suggesting prediction AML rupture based on tumor size is not always reliable. METHODS: The authors searched PubMed using "angiomyolipoma," "AML," and "rupture" and reviewed relevant studies...

Tumor-associated macrophages can promote growth of cancers. In neuroblastoma, tumor-associated macrophages have greater frequency in metastatic versus loco-regional tumors, and higher expression of genes associated with macrophages helps to predict poor prognosis in the 60% of high-risk patients who have MYCN-non-amplified disease. The contribution of cytotoxic T-lymphocytes to anti-neuroblastoma immune responses may be limited by low MHC class I expression and low exonic mutation frequency. Therefore, we modelled human neuroblastoma in T-cell deficient mice to examine whether depletion of monocytes/macrophages from the neuroblastoma microenvironment by blockade of CSF-1R can improve the response to chemotherapy...
