Second TURB, restaging TURB or repeat TURB in primary T1 non-muscle invasive bladder cancer: impact on prognosis?

Purpose: A re-transurethral resection of the bladder (re-TURB) is a well-established approach in managing non-muscle invasive bladder cancer (NMIBC) for various reasons: repeat-TURB is recommended for a macroscopically incomplete initial resection, restaging-TURB is required if the first resection was macroscopically complete but contained no detrusor muscle (DM) and second-TURB is advised for all completely resected T1-tumors with DM in the resection specimen. This study assessed the long-term outcomes after repeat-, second-, and restaging-TURB in T1-NMIBC patients.

Methods: Individual patient data with tumor characteristics of 1660 primary T1-patients (muscle-invasion at re-TURB omitted) diagnosed from 1990 to 2018 in 17 hospitals were analyzed.

Prognosis of Primary Papillary Ta Grade 3 Bladder Cancer in the Non-muscle-invasive Spectrum.

Background: Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC) is a relatively rare diagnosis with an ambiguous character owing to the presence of an aggressive G3 component together with the lower malignant potential of the Ta component. The European Association of Urology (EAU) NMIBC guidelines recently changed the risk stratification for Ta G3 from high risk to intermediate, high, or very high risk. However, prognostic studies on Ta G3 carcinomas are limited and inconclusive.

T1G1 Bladder Cancer: Prognosis for this Rare Pathological Diagnosis Within the Non-muscle-invasive Bladder Cancer Spectrum.

Background: The pathological existence and clinical consequence of stage T1 grade 1 (T1G1) bladder cancer are the subject of debate. Even though the diagnosis of T1G1 is controversial, several reports have consistently found a prevalence of 2-6% G1 in their T1 series. However, it remains unclear if T1G1 carcinomas have added value as a separate category to predict prognosis within the non-muscle-invasive bladder cancer (NMIBC) spectrum.

Optimal Surgical Outcome of Minimally Invasive Partial Nephrectomy (MIPN) Based on an Early Postoperative Estimated Glomerular Filtration Rate (eGFR).

Purpose Of Review: To compare laparoscopic partial nephrectomy (LPN) and robot-assisted partial nephrectomy (RAPN) performed in two European tertiary centers using the classic optimal surgical definition - "MIC" - and a new optimal surgical definition: the "Novel TRIFECTA" (NT) concept. We sought to strengthen the PN evidence and to test the NT's performance.

Recent Findings: The study population comprehended 505 cases of localized kidney cancer from two tertiary centers between 2012 and 2019.

European Association of Urology (EAU) Prognostic Factor Risk Groups for Non-muscle-invasive Bladder Cancer (NMIBC) Incorporating the WHO 2004/2016 and WHO 1973 Classification Systems for Grade: An Update from the EAU NMIBC Guidelines Panel.

Background: The European Association of Urology (EAU) prognostic factor risk groups for non-muscle-invasive bladder cancer (NMIBC) are used to provide recommendations for patient treatment after transurethral resection of bladder tumor (TURBT). They do not, however, take into account the widely used World Health Organization (WHO) 2004/2016 grading classification and are based on patients treated in the 1980s.

Objective: To update EAU prognostic factor risk groups using the WHO 1973 and 2004/2016 grading classifications and identify patients with the lowest and highest probabilities of progression.

Papillary urothelial neoplasm of low malignant potential (PUN-LMP): Still a meaningful histo-pathological grade category for Ta, noninvasive bladder tumors in 2019?

Background: Papillary urothelial neoplasm of low malignant potential (PUN-LMP) was introduced as a noninvasive, noncancerous lesion and a separate grade category in 1998. Subsequently, PUN-LMP was reconfirmed by World Health Organization (WHO) 2004 and WHO 2016 classifications for urothelial bladder tumors.

Objectives: To analyze the proportion of PUN-LMP diagnosis over time and to determine its prognostic value compared to Ta-LG (low-grade) and Ta-HG (high-grade) carcinomas.

Placental Growth Factor in Bladder Cancer Compared to the Diagnostic Accuracy and Prognostic Performance of Vascular Endothelial Growth Factor A.

Background/aim: To evaluate the diagnostic accuracy and prognostic performance of urinary and plasma levels of placental growth factor (PLGF) and provide their comparison with the results of vascular endothelial growth factor A (VEGF-A) in patients with primary and recurrent urinary bladder cancer.

Materials And Methods: The enzyme-linked immunosorbent assay (ELISA) was used to assess urinary and plasma concentrations of PLGF and VEGF-A in 240 individuals.

Results: PLGF levels in urine and plasma were significantly higher in patients with primary bladder cancer than in healthy individuals (p=0.

Prognosis of Castration-resistant Prostate Cancer Patients - Use of the AdnaTest® System for Detection of Circulating Tumor Cells.

Background: Detection of circulating tumor cells (CTC) in patients with castration-resistant prostate cancer (CRPC) may improve the estimate of chemotherapy response. We evaluated the AdnaTest® system in patients receiving docetaxel.

Patients And Methods: CTC analysis was carried out in 37 patients by immunomagnetic separation.

Diagnostic Importance of Selected Protein Serum Markers in the Primary Diagnostics of Prostate Cancer.

Objective: To determine a predictive model for the primary diagnosis of prostate cancer (PC) based on a multiple serum biomarker assay.

Material And Methods: Between August 2011 and February 2013, a total of 387 prostate biopsies were performed. Serum or plasma concentrations of 22 biomarkers (neopterin, IGF-1, IGFBP-2, IGFBP-3, sarcosine, endoglin, TGF-β1, periostin, sPLA2-IIa, chromogranin A, ZAG2, clusterin, PSP94, PSP94bp, leptin, cathepsin D, hepsin, KLK11, PSMA, AMACR, CRISP3 and A1AT) were determined.

Panel of Urinary Diagnostic Markers for Non-Invasive Detection of Primary and Recurrent Urothelial Urinary Bladder Carcinoma.

Objectives: To determine the combination of urinary protein markers for noninvasive detection of primary and recurrent urothelial bladder carcinomas.

Methods: Urinary concentrations of 27 biomarkers (NSE, ATT, AFABP, Resistin, Midkine, Clusterin, Uromodulin, ZAG2, HSP27, HSP 60, NCAM1/CD56, Angiogenin, Calreticulin, Chromogranin A, CEACAM1, CXCL1, IL13Ra2, Progranulin, VEGFA, CarbAnhydIX, Annexin-V, TIM4, Galectin1, Cystatin B, Synuclein G, ApoA1 and ApoA2) were assessed by enzyme-linked immunosorbent assay or by electrochemiluminiscence immunoassay.

Results: During the primary diagnostics, a group of 70 patients with primary occurrence of bladder cancer and 49 healthy control subjects were compared.

Ovarian metastasis of clear cell renal cell carcinoma: A case report.

We report on a 61-year-old woman with a history of right-sided nephrectomy for clear cell renal cell carcinoma (RCC) occurring 21 years ago; she currently presented with a bilateral ovarian tumour. Histologically, the tumour of both ovaries was clear cell carcinoma. Immunohistochemically, the tumour cells were positive for vimentin, RCC marker, epithelial membrane antigen, cytokeratin AE1/3 and CD10.

Narrow band imaging cystoscopy improves the detection of non-muscle-invasive bladder cancer.

Objectives: To determine whether narrow band imaging (NBI) improves detection of non-muscle-invasive bladder cancer over white-light imaging (WLI) cystoscopy.

Methods: We conducted a prospective, within-patient comparison on 103 consecutive procedures on 95 patients scheduled for (re-) transurethral resection of a bladder tumor (84) or bladder biopsies (19) in the Academic Medical Center, Amsterdam (September 2007-July 2009) and in the General Faculty Hospital, Prague (January 2009-July 2009). WLI and NBI cystoscopy were subsequently performed by different surgeons who independently indicated all tumors and suspect areas on a bladder diagram.
