Major clinical issues in bladder cancer include the identification of prediction markers and novel therapeutic targets for invasive bladder cancer. In the current study, we describe the isolation and characterization of a tumor-initiating cell (T-IC) subpopulation in primary human bladder cancer, based on the expression of markers similar to that of normal bladder basal cells (Lineage-CD44(+)CK...

RAB42, member rat sarcoma oncogene family was proved to play a key role in cancer-promoting progression. However, its function the progression of bladder cancer still uncertain. We explored and pan-cancer using bioinformatics analysis, including expression, prognostic, genetic alteration, functional pathways, tumor microenvironment drug resistance. Our results indicated that expression increase...

Atypical bladder leiomyoma is a rare bladder tumor that is difficult to be correctly identified by imaging techniques or cystoscopy. We present the imaging characteristics of an atypical bladder leiomyoma and review the relative literature, with the aim of enhancing awareness of the differential diagnosis of bladder leiomyoma, to avoid and reduce misdiagnosis. The imaging characteristics of the...

Primary signet-ring cell adenocarcinoma of the urinary bladder is a rare tumor. We report in this study the case of a 53 year old man consulting for gross hematuria. Computed tomography imaging demonstrated right hydronephrosis and an invasive bladder tumor. The bladder biopsy showed a signetring cell carcinoma; the exploration of the gastrointestinal tract did nor reveal any other tumor locali...

PURPOSE Although transurethral resection of the bladder tumor (TURBT) is still regarded as thegold standard for the treatment of clinical non-muscle invasive bladder cancer, alternative surgical options remain investigating. Our aim was to evaluate the efficacy and safety of potassium- titanyl-phosphate (KTP) laser for the treatment of primary, clinically non-muscle invasive bladder cancer comp...

Chemoimmunotherapy in two animal models for urological cancers was studied. The models were Dunning R3327A prostatic carcinoma transplanted s.c. in Fischer X Copenhagen F1 hybrids and a well-differentiated bladder carcinoma transplanted orthotopically in the bladder submucosa of female Fischer rats. Cyclophosphamide, cis-platinum, and Adriamycin were initially used as anticancer chemotherapeuti...

The models were Dunning R3327A prostatic carcinoma transplanted s.c. in Fischer x Copenhagen F, hybrids and a well-differentiated bladder carcinoma transplanted orthotopically in the bladder submucosa of female Fischer rats.

Purpose: p21 protein is an inhibitor of cyclin-dependent kinases, which may be able to arrest the cell cycle at the G1 phase by inhibiting DNA replication through the interaction with proliferating cell nuclear antigen. From experimental studies, p21 has been considered a tumor suppressor gene. Herein, the effects of p21 on the development, stage, grade, recurrence, progression and patient's su...

The reactivities of two anti-bladder cancer monoclonal antibodies, AN43 and BB369, were characterized. AN43 and BB369 reacted with a majority (greater than 50%) of bladder cancer tissue sections tested by immunoperoxidase staining. When tested against a panel of 27 normal human tissues, AN43 and BB369 reacted only with urothelium and stomach. AN43 and BB369 showed identical binding patterns and...

The two-stage clonal expansion model for a single, less-than-lifetime period of dosing is formulated and applied to the liver and bladder tumor data from the ED01 study. The model successfully predicts liver tumor incidence for time points beyond termination of dosing with 2-acetylaminofluorene, but it is unsuccessful for bladder tumor incidence. A discontinued dosing version of the Weibull mod...
