Bacillus Calmette-Guérin (BCG) is an attenuated strain of Mycobacterium bovis that has been effectively used in the treatment of non-muscle invasive bladder carcinoma. The complications of this treatment are uncommon, and the causes of dissemination are still discussed. We report a case of disseminated tuberculosis in a 66-year-old smoking man without a history of pulmonary diseases, who underwent immunotherapy with BCG after the initial surgical treatment of bladder cancer. After the last BCG instillation, he developed a fever. The diagnosis of sepsis was not confirmed, and miliary pulmonary tuberculosis was suspected. The diagnosis was confirmed by clinical manifestation, computed tomography of the lungs, and histological examination.

Urinary bladder cancer is a common malignancy, being characterized by substantial patient mortality and management cost. Its high somatic-mutation frequency and molecular heterogeneity usually renders tumors refractory to the applied regimens. Hitherto, methotrexate-vinblastine-adriamycin-cisplatin and gemcitabine-cisplatin represent the backbone of systemic chemotherapy. However, despite the initial chemosensitivity, the majority of treated patients will eventually develop chemoresistance, which severely reduces their survival expectancy. Since chromatin regulation genes are more frequently mutated in muscle-invasive bladder cancer, as compared to other epithelial tumors, targeted therapies against chromatin aberrations in chemoresistant clones may prove beneficial for the disease. “Acetyl-chromatin” homeostasis is regulated by the opposing functions of histone acetyltransferases (HATs) and histone deacetylases (HDACs). The HDAC/SIRT (super-)family contains 18 members, which are divided in five classes, with each family member being differentially expressed in normal urinary bladder tissues. Since a strong association between irregular HDAC expression/activity and tumorigenesis has been previously demonstrated, we herein attempt to review the accumulated published evidences that implicate HDACs/SIRTs as critical regulators in urothelial bladder cancer. Moreover, the most extensively investigated HDAC inhibitors (HDACis) are also analyzed, and the respective clinical trials are also described. Interestingly, it seems that HDACis should be preferably used in drug-combination therapeutic schemes, including radiation.

Urinary bladder cancer is one of the most prevalent cancers worldwide.Squamous Cell Carcinoma (SCC) is an uncommon subtype of urinary bladder carcinoma.It is a malignant epithelial neoplasm arising in the urinary bladder demonstrating a pure squamous cell phenotype. On histopathology it is considered when tumor is showing pure squamous morphology without any component of conventional urothelial carcinoma. The SCC is a histologically distinct form of cancer. It arises from the uncontrolled multiplication of cells showing particular cytological or tissue architectural characteristics of squamous cell differentiation, such as the presence of keratin, tonofilament bundles or desmosomes. Majority of bladder SCC are high grade, high stage tumors with most cancers having muscle invasion at the time of diagnosis while overall about 80% of bladder cancers are non-muscle invasive bladder cancer at diagnosis.COX-2 is markedly expressed in all SCCs. An increased COX-2 level induces the development of SCC of the bladder affecting many biological features of this tissue including apoptosis, cell adhesion, angiogenesis and invasiveness.TERT promoter mutations, commonly found in conventional urothelial carcinoma, are also highly prevalent in urinary bladder squamous cell carcinoma suggesting a common tumorgenesis and potential utility as a molecular urine-based-screening assay.This review summarizes the current features related to clinical , pathological, and molecular features of SCC of urinary bladder.

Objective: To explore the utility of first-order MRI-texture analysis (TA) parameters in predicting histologic grade and muscle invasion in urinary bladder cancer (UBC). Methods: After ethical clearance, 40 patients with UBC, who were imaged on a 3.0-Tesla scanner, were retrospectively included. Using the TexRADTM platform, two readers placed freehand ROI on the sections demonstrating the largest dimension of the tumor, evaluating only one tumor per patient. Interobserver reproducibility was assessed using the intraclass correlation coefficient (ICC). Mann–Whitney U test and ROC curve analysis were used to identify statistical significance and select parameters with high class separation capacity (AUC >0.8), respectively. Pearson’s test was used to identify redundancy in the results. Results: All texture parameters showed excellent ICC. The best parameters in differentiating high and low-grade tumors were mean/ mean of positive pixels (MPP) at SSF 0 (AUC: 0.897) and kurtosis at SSF 5 (AUC: 0.828) on the ADC images. In differentiating muscle invasive from non-muscle invasive tumors, mean/ MPP at SSF 0 on the ADC images showed AUC >0.8; however, this finding resulted from the confounding effect of high-grade histology on the ADC values of muscle invasive tumors. Conclusion: MRI-TA generated few parameters which were reproducible and useful in predicting histologic grade. No independent parameters predicted muscle invasion. Advances in knowledge: There is lacuna in the literature concerning the role of MRI-TA in the prediction of histologic grade and muscle invasion in UBC. Our study generated a few first-order parameters which were useful in predicting high-grade histology.
