Characterization of PD-1 and PD-L1 Expression in Papillary Renal Cell Carcinoma: Results of a Large Multicenter Study
2021
Abstract Background Programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) play a decisive role as prognostic markers in clear-cell renal cell carcinoma (RCC). To date, the role of PD-1/PD-L1 as a prognostic marker in papillary RCC (pRCC) remains scarce. Patients and Methods Patients’ sample collection was a joint collaboration of the nationwide PANZAR consortium – a multicenter study. Medical history and tumor specimens were collected from 245 and 129 patients with pRCC types 1 and 2, respectively. Expression of PD-1 and PD-L1 was determined by immunohistochemistry in pRCC and tumor-infiltrating mononuclear cells. Results Of 374 pRCC specimens, 204 type 1 and 97 type 2 we…
The Use of Neoadjuvant Chemotherapy in Patients With Urothelial Carcinoma of the Bladder: Current Practice Among Clinicians.
2017
Abstract Introduction Guidelines recommend neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) in patients with urothelial carcinoma of the bladder in clinical stages T2-T4a, cN0M0. We examined the frequency and current practice of NAC and sought to identify predictors for the use of NAC in a prospective contemporary cohort. Materials and Methods We analyzed prospective data from 679 patients in the PROMETRICS (PROspective MulticEnTer RadIcal Cystectomy Series 2011) database. All patients underwent RC in 2011. Uni- and multivariable regression analyses identified predictors of NAC application. Furthermore, a questionnaire was used to evaluate the practice patterns of NAC at the PR…
Solifenacin in the Elderly: Results of an Observational Study Measuring Efficacy, Tolerability and Cognitive Effects.
2015
<b><i>Introduction:</i></b> The study aimed to evaluate the efficacy and safety of solifenacin in older patients with overactive bladder (OAB). <b><i>Materials and Methods:</i></b> Observational data on patients aged ≥70 years and the prescribed flexible dose of solifenacin for OAB were collected at 294 offices of German general practitioners. Baseline and week 12 data included type and severity of OAB symptoms, adverse events, quality of life, and change in cognitive function per Mini Mental State Examination (MMSE). <b><i>Results:</i></b> Mean age of 774 patients was 78 ± 6 years. A decrease was observed in all OAB sy…
High proliferation rate and TNM stage but not histomorphological subtype are independent prognostic markers for overall survival in papillary renal c…
2018
Papillary renal cell carcinoma (PRCC) is currently divided in 2 subtypes. We reviewed a large cohort of PRCC and correlated subtype, morphological features and diagnostic marker expression with overall survival (OS) to uncover differences between the 2 subtypes. Three hundred seventy-six renal tumors initially diagnosed as PRCC with clinical and survival data were collected from the participating centers. Two hundred forty-six tumors were classified as PRCC1 (65.4%) and 130 as PRCC2 (34.6%) and graded according to the 2016 World Health Organization/International Society of Urological Pathology grading system. Morphological features (abundant cytoplasm, necrosis, fibrous stroma, foamy macrop…
Accordance of Online Health Information on Prostate Cancer with the European Association of Urology Guidelines.
2017
<b><i>Background:</i></b> The internet is an emerging source of information for prostate cancer (PCa) patients. Since little is known about the quality of information on PCa provided online, we investigated its accordance to the latest European Association of Urology (EAU) guidelines. <b><i>Methods:</i></b> A total of 89 German web pages were included for analysis. A quality model classifying the provider of information and its expertise was introduced. Correctness of provided information was systematically compared to the EAU guidelines. <b><i>Results:</i></b> Information was provided by medical experts (41%), media (1…
ICUD-EAU International Consultation on Bladder Cancer 2012: Non–Muscle-Invasive Urothelial Carcinoma of the Bladder
2012
Item does not contain fulltext CONTEXT: Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. OBJECTIVE: To critically review the recent data on the management of NMIBC to arrive at a general consensus. EVIDENCE ACQUISITION: A detailed Medline analysis was performed for original articles addressing the treatment of NMIBC with regard to diagnosis, surgery, intravesical chemotherapy, and follow-up. Proceedings from the last 5 yr of major conferences were also searched. EVIDENCE SYNTHESIS: The major findi…
Aquaporin 3 Expression Loss in Urothelial Carcinoma: Association with Tumor Invasion Depth, but not with Grading?
2017
We have previously provided molecular evidence of expression of aquaporin 3 (AQP3) in normal human urothelium and in UBC of various stages. Whereas former studies demonstrated that loss of AQP3 was associated with invasive and high-grade disease and worse progression-free and cancer-specific survival, this report investigates the expression of AQP3 in associated CIS. Contrary to what we had expected, all CIS specimens were shown to exhibit strong AQP3 expression, suggesting loss of AQP3 in UBC is primarily associated with the ability of tumor cells for invasion but not with grading as sign of dedifferentiation.
