Unmet Need in Non-muscle-invasive Bladder Cancer Failing Bacillus Calmette-Guérin Therapy: A Systematic Review and Cost-effectiveness Analyses from the International Bladder Cancer Group.

Background And Objective: Non-muscle-invasive bladder cancer (NMIBC) poses a significant clinical challenge, particularly when failing bacillus Calmette-Guérin (BCG) therapy, necessitating alternative treatments. Despite radical cystectomy being the recommended treatment, many patients are unfit or unwilling to undergo this invasive procedure, highlighting the need for effective bladder-sparing therapies. This review aims to summarize and report the evidence on the efficacy and to estimate the costs of bladder-preserving strategies used in NMIBC recurrence after failure of intravesical BCG therapy.

Clinical and pathological features of renal tumours among women previously treated for breast carcinomas - the CanSeRe study.

Introduction: Renal cell carcinoma (RCC) and breast carcinoma (BC) are frequent tumours, yet their co-occurrence in the same patient is a unique scenario. Few studies explored the characteristics of such patients without specific focus on pathological data. In this retrospective study, we aimed to describe the clinico-pathological features of RCC patients with a history of BC and compare them to a control cohort of RCC women free of previous BC.

Results: The predominant genetic mechanism leading to the MSI/dMMR phenotype in UTUC patients is related to the constitutional mutation of one allele of the MMR genes MLH1, MSH2, MSH6 and PMS2 within Lynch syndrome.

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.

Management of high-grade papillary Ta or T1 bladder cancer after restaging transurethral resection: A retrospective study comparing Bacillus Calmette-Guerin therapy upfront versus a third resection.

Purpose: Performing restaging transurethral bladder resection (reTURB) for high-risk non-muscle invasive bladder cancer (NMIBC) reduces the risk of recurrence and tumour understaging. Management of residual high-grade papillary Ta or T1 after reTURB has changed this last 10years in international recommendations. This study aimed to compare the recurrence free survival according to the different management procedures performed.

[Profile and immune environment of upper tract urothelial carcinoma].

Introduction And Objectives: Upper Tract Urothelial Carcinoma (UTUC) are tumors that share similarities with bladder tumors. Immunotherapy is already used for bladder locations and appears to have interest for UTUC. In order to rationalize the immunotherapy development pipeline it seemed necessary to describe the immune infiltrate of a cohort of UTUC treated with nephroureterectomy and to determine the expression of a panel of immune checkpoints and co-stimulatory molecules on tumor cells as well as on infiltrating and circulating lymphocytes.

Prognosis of patients with T1 low-grade urothelial bladder cancer treated with bacillus Calmette-Guérin immunotherapy.

Background: The existence and prognosis of T1LG (T1 low-grade) bladder cancer is controversial. Also, because of data paucity, it remains unclear what is the clinical history of bacillus Calmette-Guérin (BCG) treated T1LG tumors and if it differs from other NMIBC (non-muscle-invasive bladder cancer) representatives. The aim of this study was to analyse recurrence-free survival (RFS) and progression-free survival (PFS) in patients with T1LG bladder cancers treated with BCG immunotherapy.

Design and rationale of a single-arm phase II study of neoadjuvant Durvalumab and Gemcitabine associated with Cisplatin or Carboplatin for upper urinary tract urothelial cancer: the iNDUCT trial (NCT04617756).

Background: Upper urinary tract urothelial carcinoma (UTUC) is often locally advanced at initial diagnosis and is associated with high recurrence and mortality rates after radical nephroureterectomy (RNU). Adjuvant platinum-based chemotherapy has shown a recurrence-free survival benefit in a randomised phase III trial, while neoadjuvant treatment seems promising in retrospective series. On the contrary, little is known about the role of perioperative immunotherapy and its combination with chemotherapy for UTUC patients, although initial positive results have been published for muscle-invasive bladder cancer.

Transcriptomic Profiling of Upper Tract Urothelial Carcinoma: Bladder Cancer Consensus Classification Relevance, Molecular Heterogeneity, and Differential Immune Signatures.

Analyses of large transcriptomics data sets of muscle-invasive bladder cancer (MIBC) have led to a consensus classification. Molecular subtypes of upper tract urothelial carcinomas (UTUCs) are less known. Our objective was to determine the relevance of the consensus classification in UTUCs by characterizing a novel cohort of surgically treated ≥pT1 tumors.

Safety and efficacy of preoperative chemotherapy for muscle-invasive bladder cancer in elderly patients.

Purpose: This study aimed at describing the feasibility and oncological outcomes of standard cisplatin-based neoadjuvant chemotherapy (C-NAC) for muscle-invasive bladder cancer (MIBC) in patients aged ≥ 75 and assess the impact of baseline geriatric parameters.

Methods: This retrospective study included patients with stage cT2-4NanyM0 MIBC aged 75 and older treated with ≥ 1 cycle of C-NAC from 2011 to 2021 at a high-volume academic center. Primary outcome was overall survival (OS).

[Preoperative chemotherapy for patients with upper tract urothelial carcinoma: Impact on renal function].

Purpose: Upper tract urothelial carcinoma (UTUC) are rare tumors with a poor prognosis. The standard treatment for localized disease is based on total nephroureterectomy (NUT) followed by platinum-based adjuvant chemotherapy for eligible patients at risk of recurrence. However, many patients have renal failure after surgery preventing chemotherapy.

Survival after sequential neoadjuvant chemotherapy followed by trimodal treatment or radical cystectomy for muscle-invasive bladder cancer.

Purpose: to assess the respective outcomes of patients with localized muscle-invasive bladder cancer (MIBC) treated by either radical cystectomy (RC) or trimodal treatment (TMT) depending on pathological response to previous neoadjuvant chemotherapy (NAC) assessed on cystectomy specimen or post-NAC transurethral resection (TURB) specimen, respectively.

Patient And Methods: We retrospectively included all consecutive patients treated in one academic center with cisplatin-based NAC followed by RC or TMT for cT2-3N0M0 MIBC between 2014 and 2021. Primary endpoint was metastasis-free survival (MFS) in both treatment groups and according to pathological response to NAC.

International Opinions on Grading of Urothelial Carcinoma: A Survey Among European Association of Urology and International Society of Urological Pathology Members.

Background: Grade of non-muscle-invasive bladder cancer (NMIBC) is an important prognostic factor for progression. Currently, two World Health Organization (WHO) classification systems (WHO1973, categories: grade 1-3, and WHO2004 categories: papillary urothelial neoplasm of low malignant potential [PUNLMP], low-grade [LG], high-grade [HG] carcinoma) are used.

Objective: To ask the European Association of Urology (EAU) and International Society of Urological Pathology (ISUP) members regarding their current practice and preferences of grading systems.
