The emergence of chemoresistance greatly increases the recurrence risk for non-muscle invasive bladder cancer (NMIBC) patients, which is still a big concern of clinicians. Understanding the mechanisms of drug resistance is of great significance for preventing and reversing it. We showed here that CXC motif chemokine ligand 5 (CXCL5) was overexpressed in mitomycin C-resistant bladder cancer cell line M-RT4. Meanwhile, parental RT4 cell treated with recombinant human CXCL5 (rhCXCL5) reduced its sensitivity to mitomycin C...

Bladder cancer (BCa) is the fifth most frequently diagnosed cancer worldwide and is, in fact, the most expensive cancer on a per-patient to treat basis. There is a critical need to implement new tests into clinical practice to improve the quality of clinical care, decrease unnecessary invasive therapies and ultimately save costs. Currently, no molecular or genetic biomarker has been widely integrated into daily clinical practice. However, major milestones have been achieved in our understanding of the molecular alterations in BCa that will provide the basis for integrating molecular and genetic biomarkers into clinical decision making to guide management...

Intravesical BCG therapy after transurethral resection of bladder tumor (TURB) is considered the most effective treatment for prophylaxis against the recurrence of high risk non-muscle invasive bladder cancer, and generally well tolerated and infectious complication are rare. We reported a case of granulomatous prostatitis is a patient who had undergone intravesical BCG therapy due to non-invasive superficial urothelial carcinoma of bladder. This patient was diagnosed by prostate biopsy because of PSA elevation without any other voiding symptoms and abnormal abscess pocket in transrectal ultrasonography...

Bladder cancer is among the most frequent types of genitourinary malignancies and results in high morbidity and mortality. Despite considerable progress in methods of bladder cancer diagnosis and treatment, the detailed underlying molecular mechanisms of bladder cancer remain unclear, and the prognosis of patients remains poor. In the present study, the role of long non-coding (lnc)RNA hepatocyte nuclear factor 1A (HNF1A)-antisense RNA (AS)1 in bladder cancer progression was examined in vitro . HNF1A-AS1 was overexpressed in clinical bladder cancer tissues and cultured bladder cancer cells...

Analyses of microRNA (miRNA) expression signatures obtained by RNA sequencing revealed that some passenger miRNAs (miR-144-5p, miR-145-3p, miR-149-3p, miR-150-3p, and miR-199a-3p) acted as anti-tumor miRNAs in several types of cancer cells. The involvement of passenger strands in the pathogenesis of human cancer is a novel concept. Based on the miRNA signature of bladder cancer (BC) obtained by RNA sequencing, we focused on both strands of the miR-223-duplex (miR-223-5p and miR-223-3p) and investigated their functional significance in BC cells...

Background: Patients with cancer are highly concerned about food choices and dietary supplements that may affect their treatment outcomes. Excess folic acid (synthetic folate) from supplements or fortification can lead to accumulation of unmetabolized folic acid in the systemic circulation and urine and may promote cancer growth, especially among those with neoplastic alterations. Objective: We investigated the prospective association between synthetic compared with natural folate intake and clinical outcomes in non-muscle-invasive bladder cancer (NMIBC), which is a highly recurrent disease...

Non-muscle-invasive bladder cancer (NMIBC) is a highly recurrent disease. Early bladder chemotherapy instillation (EBCI) after transurethral resection (TURB) is an efficient way to diminish recurrence. However, this method is often challenged. Areas covered: There was a recent publication of a large meta-analysis with the original patient data and the largest study ever on EBCI. Both brought new evidence on EBCI. Also the results of the 2 trials of EBCI with apaziquone appeared. EBCI is discussed among other methods to decrease recurrence...

CONTEXT: Initial treatment for most bladder cancers (BCs) involves transurethral resection (TUR) or tumours. Often more cancer is found after the initial treatment in around half of patients, requiring a second resection. Repeat transurethral resection (reTUR) is recommended for high-risk, non-muscle-invasive bladder cancer (NMIBC) to remove any residual disease and improve cancer outcomes. OBJECTIVE: To systematically review the practice and therapeutic benefit of an early reTUR for high-risk NMIBC...
