Non-muscle-invasive bladder cancer (NMIBC) is a highly recurrent tumor despite intravesical immunotherapy instillation with the bacillus Calmette-Guérin (BCG) vaccine. In a prospective longitudinal study, we took advantage of BCG instillations, which increase local immune infiltration, to characterize immune cell populations in the urine of patients with NMIBC as a surrogate for the bladder tumor microenvironment. We observed an infiltration of neutrophils, T cells, monocytic myeloid-derived suppressor cells (M-MDSCs), and group 2 innate lymphoid cells (ILC2)...

Among the many milestones in the last several decades in the management of muscle-invasive bladder cancer and high-risk nonmuscle-invasive bladder cancer including the extension of the standard lymph node dissection and the use of neoadjuvant chemotherapy, minimally invasive techniques have gained traction as an attractive option for radical cystectomy. Open radical cystectomy is plagued with high rates of perioperative and postoperative morbidity and mortality, and as robotic assistance has demonstrated benefits in other arenas of surgery and urology, the evolution of the approach to radical cystectomy has likewise incorporated robotic assistance...

BACKGROUND: Recent studies have demonstrated that the expression of long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) promotes cancer cell proliferation, invasion, and metastasis in many tumor types, but the association between bladder cancer and MALAT1 remains unknown. MATERIALS: The expression of MALAT1 was tested by in situ hybridization (ISH) in 120 bladder cancer specimens. The association between MALAT1 expression and clinicopathological features and prognosis of the patients with bladder cancer was analyzed...

INTRODUCTION: It is 40 years since the initial documentation of the efficacy of bacille Calmette-Guérin (BCG) in the management of non-muscle invasive bladder cancer (NMIBC) and probably an opportune a time as any to retrace the origins of this development and to reflect on the progress that has occurred on the use of immune modifiers in the treatment of NMIBC. MATERIALS AND METHODS: A PubMed search for publications on the history of BCG was conducted, and those related to the development of the vaccine for protection against tuberculosis as well as those published in the last 40 years related to its use for treatment for NMIBC were selected for review...

Secondary bladder neck sclerosis represents one of the more frequent complications following endoscopic, open, and other forms of minimally invasive prostate surgery. Therapeutic decisions depend on the type of previous intervention (e.g., radical prostatectomy, TURP, HoLEP, radiotherapy, HIFU) and on associated complications (e.g., incontinence, fistula). Primary treatment in most cases represents an endoscopic bilateral incision. No specific advantages of any type of the applied energy (i.e., mono-/bipolar HF current, cold incision, holmium/thulium YAG laser) could be documented...

OBJECTIVE: The Danish hematuria guidelines were revised in January 2016. Before revision, it was recommended that asymptomatic microscopic hematuria in patients more than 40 years old should be routinely urologically investigated. In the revised guidelines, patients with asymptomatic microscopic hematuria are not recommended to be investigated, irrespective of age. The purpose of this study was to investigate whether asymptomatic microscopic hematuria was predictive of neoplasia of the urinary tract in a referred cohort of patients...

BACKGROUND: The majority of anal cancers (84-95%) are driven by infection with human papillomavirus (HPV). HPV-positive tumours show significantly better responses to chemo-radiotherapy when compared with HPV-negative tumours. HPV infection is linked to alterations in DNA damage response proteins, including MRE11. MRE11 is a potential predictive biomarker for response to radiotherapy in muscle-invasive bladder cancer and may hold predictive power in other cancers. METHODS: Using a previously reported cohort, we evaluated the levels of MRE11 in anal cancer and assessed its predictive value in this disease...

Extraperitoneal bladder perforation is a known complication of a commonly performed rigid cystoscopy. If unrecognized, this complication can lead to continuous intra-abdominal fluid leakage with consequent organ function impairment and symptoms. This is the first case report in literature of a transurethral bladder perforation causing an acute abdominal compartment syndrome, which was subsequently managed conservatively with supportive management only. Case Presentation. We describe a clinical course of a 73-year-old Caucasian female whose initial acute presentation involved urinary symptoms...

Apaziquone (also known as EO9 and Qapzola) is a prodrug that is activated to DNA damaging species by oxidoreductases (particularly NQO1) and has the ability to kill aerobic and/or hypoxic cancer cells. Areas covered: Whilst its poor pharmacokinetic properties contributed to its failure in phase II clinical trials when administered intravenously, these properties were ideal for loco-regional therapies. Apaziquone demonstrated good anti-cancer activity against non-muscle invasive bladder cancer (NMIBC) when administered intravesically to marker lesions and was well tolerated with no systemic side effects...

Robot-assisted radical cystectomy (RARC) has been adopted widely in many centres, owed largely to the success of robot-assisted laparoscopic prostatectomy (RALP). It aims to replicate the oncological outcomes of open radical cystectomy (ORC), while providing a shorter recovery period. Despite this, previous RCTs have failed to show a benefit for RARC over ORC. These trials have compared extracorporeal RARC (eRARC) with ORC, which requires a further incision to mobilise the bowel for urinary reconstruction with an open technique...

Perioperative chemotherapy is likely to improve survival in both the neoadjuvant and the adjuvant setting. Therefore, it is an integral part of the modern treatment of patients with muscle-invasive urothelial bladder cancer. All patients who are suitable for cisplatin-based chemotherapy should be involved in a corresponding concept.Cisplatin-based combinations are standard regimens in the perioperative and palliative systemic treatment of urothelial cancer. Carboplatin is only an inferior substitute for "unfit" patients in the palliative treatment situation...

The mechanism of dsRNA-induced gene activation (RNAa) is being gradually unveiled. The plentiful evidence that it existed in mammalian species other than human demonstrated that dsRNA-mediated RNAa is a conservative phenomenon. Simultaneously, accumulating evidence suggested that microRNAs could activate gene expression by targeting promoter. Nevertheless, it is ambiguous whether microRNA-induced gene activation in different human cells is a common phenomenon. The study we performed verified that miR-1236-3p (miR-1236) and miR-370-5p can activate p21 expression in bladder cancer (BCa) T24, EJ cells, and non-small-cell lung carcinoma A549 cells, while in hepatocellular HepG2 cells both microRNAs cannot effectively induce the expression of P21(WAF1/CIP1) (p21)...

INTRODUCTION: Open radical cystectomy (ORC) is currently the standard treatment for muscle-invasive bladder cancer (MIBC) without metastasis, while many patients with MIBC are not always appropriate candidates due to multiple comorbidities. To evaluate the bladder-preservation strategy, we compared the results with those obtained by ORC. PATIENTS AND METHODS: We retrospectively analyzed the data of 50 patients with MIBC treated by trimodal chemoradiotherapy with cisplatin (CDDP-radiation [CDDP-R])...
