Bladder cancer arises from the epithelial lining of the urinary bladder, and it is known as transitional cell carcinoma (TCC). Tobacco smoking is the main known contributor to urinary bladder cancer. However thirty percent of bladder tumors probably result from occupational exposure in the workplace to carcinogens. Immunotherapy by intravesicular delivery of Bacillus Calmette–Guérin (BCG) is used to treat and prevent the recurrence of superficial bladder cancer. Successful BCG immunotherapy for bladder cancer is associated with proper induction of T helper (Th)1 immunity...

Penile metastasis is an extremely rare event and mainly originate from primary pelvic tumor sites such us urinary bladder, gastro-intestinal tract and prostate and more rarely from respiratory system, bone tumors and melanoma. Here we describe the unusual presentation of two bladder urothelial cancer metastatic to the penis with no relevant clinical symptoms. Namely, a 69 years-old man with a warthy lesions of the foreskin and the glans misunderstood for a condylomata that at histological and immunohistochemical analysis showed a bladder urothelial carcinoma; and a 71 years-old man with reddish skin lesion of the glans, a previous history of bladder and urethral carcinoma and histological pagetoid spread of urothelial cancer to the glans...

AIMS: Pathologic stage T1 (pT1) bladder cancers are a clinically heterogeneous group. However, current staging guidelines for superficially invasive cancers do not acknowledge the variability in type and extent of lamina propria invasion in papillary urothelial carcinomas (PUC), and historically proposed substaging systems showed either high inter-observer variation or limited value in predicting patient outcomes. Herein we reappraise pT1 PUC substaging, aiming to identify a novel scheme which is reproducible and prognostically meaningful...

The sialyl-Tn (sTn) antigen is an O-linked carbohydrate chain aberrantly expressed in bladder cancer (BC), whose biosynthesis is mainly controlled by the sialyltransferase ST6GALNAC1. Treatment with Bacillus Calmette-Guérin (BCG) is the most effective adjuvant immunotherapy for superficial BC but one third of the patients fail to respond. A poorly understood correlation between the expression of sTn and BC patient's response to BCG was previously observed. By analyzing tumor tissues, we showed that patients with high ST6GALNAC1 and IL-6 mRNA expression were BCG responders...

BACKGROUND AND OBJECTIVE: Intravesical Bacille Calmette-Guérin (BCG) is essential for preventing the recurrence and progression of superficial bladder tumours. The aim of our study was to compare the efficacy and toxicity of the Connaught and Tice strains, as well as the importance of the maintenance regimen. MATERIAL AND METHODS: We retrospectively reviewed 110 patients with superficial bladder tumours who underwent adjuvant endovesical treatment. The patients were distributed into 3 groups, based on whether the treatment was with the Connaught strain, the Tice strain or both sequentially...

The paradigm of pathologic stage (pT) categorization in bladder cancer remains the depth of invasion into the different histologic layers of the bladder wall. However, the approaches to assigning pT stage category toward an enhanced outcome stratification have been marked by challenges and innovations, due in part to our growing appreciation of the surprisingly perplexing bladder histoanatomy. Upstaging of pT1 tumors after radical cystectomy is substantial and underscores the potential value of pT1 substaging in transurethral resection (TUR) specimens...

Background. Intravesicular Bacillus Calmette-Guérin (BCG) is an effective adjunctive therapy for superficial bladder cancer that has been shown to delay recurrence and progression of disease. Serious side effects are relatively rare but are difficult to diagnosis and commonly overlooked. Case Presentation. We report the case of a patient who was found to have mycotic aortic aneurysms secondary to treatment with BCG after a prolonged course with multiple intervening hospitalizations. Conclusion. Through this report, we discuss our present understanding of BCG infection following treatment and review the literature regarding this particular rare manifestation...

Molluskan hemocyanins are enormous oxygen-carrier glycoproteins that show remarkable immunostimulatory properties when inoculated in mammals, such as the generation of high levels of antibodies, a strong cellular reaction, and generation of non-specific antitumor immune responses in some types of cancer, particularly for superficial bladder cancer. These proteins have the ability to bias the immune response toward a Th1 phenotype. However, despite all their current uses with beneficial clinical outcomes, a clear mechanism explaining these properties is not available...

BACKGROUND: Despite local therapies, commonly transurethral resection (TUR) followed by adjuvant treatments, non-muscle-invasive bladder cancer (NMIBC) has a high rate of recurrence and progression. Intravesical Bacillus Calmette-Guérin (BCG) has been shown to reduce recurrence and progression in people with NMIBC following TUR, however many people do not respond to treatment, have recurrence shortly after, or cannot tolerate standard-dose therapy. The potential for synergistic antitumour activity of interferon (IFN)-alpha (α) and BCG provides some rationale for combination therapy for people who do not tolerate or respond to standard-dose BCG therapy...

BACKGROUND Bladder cancer is a major widespread tumor of the genitourinary tract. Around 30% of patients with superficial cancers develop invasive and metastatic pathology. MATERIAL AND METHODS Some new heterocyclic 4-methyl coumarin derivatives were designed using molecular modeling studies to evaluate their potential against bladder cancer lines T24 and RT-4. The designed compounds that showed good binding affinity to T24 and RT4 were synthesized, with excellent yield. The synthesized compounds after structural evaluation were further evaluated for their antiproliferative activity by cell viability assay, cell cycle analysis, and apoptosis assay...

Henoch Schönlein purpura (HSP), also known as IgA vasculitis (IgAV), is a systemic small-vessel vasculitis that predominantly affects adolescents and is rare in adults. In many cases, the onset of HSP has been causally linked to an infectious disease. We encountered a case of HSP with severe renal involvement diagnosed by renal biopsy following bacillus Calmette-Guerin (BCG) therapy for bladder cancer. This is of clinical relevance, as intravesical BCG administration is becoming an established therapy for superficial bladder cancer and is supposed to be safe...

Cruciferous vegetable intake is associated with reduced risk of bladder cancer, yet mechanisms remain unclear. Cruciferous vegetable isothiocyanates (ITCs), namely sulforaphane (SFN) and erucin (ECN), significantly inhibit histone deacetylase (HDAC) activity in human bladder cancer cells representing superficial to invasive biology (59-83% inhibition with 20μM, 48h treatment), and in bladder cancer xenografts (59±3% ECN inhibition). Individual HDACs inhibited by SFN and ECN include HDACs 1, 2, 4 and 6. Interestingly, global acetylation status of histones H3 or H4 remain unaltered...

Lung cancer is the tumor with the highest incidence in males worldwide and the most common cause of death from cancer overall; its high mortality is mostly due to its propensity to spread to other organs through lymphatic and blood vessels in spite of proper treatment. Bladder metastases from lung cancer are rare, with only 11 cases having been reported, all in recent years. This review aims to discuss some critical points regarding this uncommon condition, namely: (a) lung and bladder tumors share similar etiologic features; (b) almost all bladder metastases from lung cancer arise from lung adenocarcinomas; (c) cytology and superficial bladder biopsy may be falsely negative, since the neoplastic cells coming through the hematogenous route are typically located in the lamina propria and/or muscularis propria of the bladder wall; and (d) the differential diagnosis with primary bladder adenocarcinoma as well as primary and secondary small-cell carcinomas may be challenging...

Intravesical gemcitabine has recently been introduced for the treatment of superficial bladder cancer and has a favourable efficacy and toxicity profile in comparison to mitomycin c (MMC), the most commonly used chemotherapeutic agent. The aim of this study was to assess the cytotoxic potency of gemcitabine in comparison to MMC in urothelial cell lines derived from non-malignant (UROtsa) and malignant (RT4 and T24) tissues to assess selectivity. Cells were treated with gemcitabine or mitomycin C at concentrations up to the clinical doses for 1 or 2h respectively (clinical duration)...

BACKGROUND/AIM: VAX014 minicells (VAX014) have been previously characterized as an integrin-specific oncolytic biotherapeutic agent. The present study was designed to evaluate the potential of VAX014 as an immediate post-operative intravesical adjuvant therapy in the treatment of non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: The ability of VAX014 to kill a panel of dissociated urothelial carcinoma cell lines was tested in vitro. In vivo experiments were conducted using a single intravesical dose of VAX014 in the anti-implantation variation of the MB49 syngeneic orthotopic bladder cancer model with tumor implantation and overall survival rates serving as study endpoints...

Non-muscle invasive (superficial) bladder cancer is a low-grade malignancy with good prognosis, while muscle invasive (invasive) bladder cancer is a high-grade malignancy with poor prognosis. N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) induces superficial bladder cancers with papillary morphology in rats and invasive bladder cancers with infiltrating phenotype in mice. In this study, we analyzed genomic landscapes of rodent BBN-induced bladder cancers using array-based comparative genomic hybridization (array CGH)...
