Electronic address:

Bladder cancer (BC) develops from the tissues of the urinary bladder and is responsible for nearly 200,000 deaths annually. This review aims to integrate knowledge of recently discovered functions of the chromatin remodelling tumour suppressor protein ARID1A in bladder urothelial carcinoma with a focus on highlighting potential new avenues for the development of personalised therapies for ARID1A mutant bladder tumours. ARID1A is a component of the SWI/SNF chromatin remodelling complex and functions to control many important biological processes such as transcriptional regulation, DNA damage repair (DDR), cell cycle control, regulation of the tumour microenvironment and anti-cancer immunity.

Selective delipidation of Mycobacterium bovis BCG retains antitumor efficacy against non-muscle invasive bladder cancer.

Cancer Immunol Immunother 2022 Jun 24. Epub 2022 Jun 24.

Experimental Developmental Therapeutics (EDT) Program, Mays Cancer Center at UT Health MD Anderson, San Antonio, TX, USA.

Purpose: Repeated instillations of bacillus Calmette et Guérin (BCG) are the gold standard immunotherapeutic treatment for reducing recurrence for patients with high-grade papillary non-muscle invasive bladder cancer (NMIBC) and for eradicating bladder carcinoma-in situ. Unfortunately, some patients are unable to tolerate BCG due to treatment-associated toxicity and bladder removal is sometimes performed for BCG-intolerance. Prior studies suggest that selectively delipidated BCG (dBCG) improves tolerability of intrapulmonary delivery reducing tissue damage and increasing efficacy in preventing Mycobacterium tuberculosis infection in mice.

Novel Antimicrobial Strategies to Prevent Biofilm Infections in Catheters after Radical Cystectomy: A Pilot Study.

Life (Basel) 2022 May 27;12(6). Epub 2022 May 27.

Andrological and Urogynecological Clinic, Santa Maria Terni Hospital, University of Perugia, 05100 Terni, Italy.

Catheter-associated infections in bladder cancer patients, following radical cystectomy or ureterocutaneostomy, are very frequent, and the development of antibiotic resistance poses great challenges for treating biofilm-based infections. Here, we characterized bacterial communities from catheters of patients who had undergone radical cystectomy for muscle-invasive bladder cancer. We evaluated the efficacy of conventional antibiotics, alone or combined with the human ApoB-derived antimicrobial peptide r(P)ApoB, to treat ureteral catheter-colonizing bacterial communities on clinically isolated bacteria.

Diagnostics (Basel) 2022 Jun 1;12(6). Epub 2022 Jun 1.

Department of Urology, University Hospital of Zurich, University of Zurich, 8091 Zurich, Switzerland.

To evaluate the prognostic value of a modified Immunoscore (mIS) in a cohort of bladder cancer (BC) patients undergoing radical cystectomy (RC), two tissue microarrays of 159 BC patients were immunohistochemically stained for CD3/CD8/FOXP3 and CD45RO to detect Tumor-Infiltrating Lymphocytes (TIL). To predict progression free survival (PFS) and cancer specific survival (CSS), a predictive model cumulatively incorporating all four components was constructed and labeled as mIS. Patients were stratified into two risk groups; "high mIS/favorable risk" and "low mIS/unfavorable risk". Read More

Acetyl-CoA Synthetase 2 as a Therapeutic Target in Tumor Metabolism.

Cancers (Basel) 2022 Jun 12;14(12). Epub 2022 Jun 12.

Institute of Oncology, Affiliated Hospital of Jiangsu University, 438 Jiefang Road, Zhenjiang 212001, China.

Acetyl-CoA Synthetase 2 (ACSS2) belongs to a member of the acyl-CoA short-chain synthase family, which can convert acetate in the cytoplasm and nucleus into acetyl-CoA. It has been proven that ACSS2 is highly expressed in glioblastoma, breast cancer, liver cancer, prostate cancer, bladder cancer, renal cancer, and other tumors, and is closely related to tumor stage and the overall survival rate of patients. Accumulating studies show that hypoxia and a low serum level induce ACSS2 expression to help tumor cells cope with this nutrient-poor environment. Read More

Efficacy of Vinflunine for Patients with Metastatic Urothelial Cancer after Immune Checkpoint Inhibitor Pretreatment-A Retrospective Multicenter Analysis.

Cancers (Basel) 2022 Jun 9;14(12). Epub 2022 Jun 9.

Department of Urology, University Hospital Ulm, 89081 Ulm, Germany.

Background: Immune checkpoint inhibitors (ICI) are standard of care in patients with metastatic urothelial carcinoma (mUC) ineligible for cisplatin, and as second-line therapy after platinum-based chemotherapy. To date, few data exist about the efficacy of the former second-line chemotherapeutic agent vinflunine after the failure of sequential platinum-based chemotherapy and ICI treatment. The aim of this analysis was to examine the efficacy of vinflunine in a post-ICI third- or later-line setting. Read More

Department of Genetics, Evolution, Microbiology, and Immunology, Tropical Disease Laboratory, Institute of Biology, University of Campinas - UNICAMP, 13083-970, Campinas, SP, Brazil.

Numerous studies have attempted to restore the function of the tumour suppressor p53 as an anticancer strategy through gene delivery. However, most studies employed non-bacterial vectors to deliver p53. Various facultative and obligate anaerobic bacteria have been proposed as vectors because of their intrinsic tumour targeting ability and antitumour activity. Read More
