Abstract
Background Data are scarce regarding intravesical maintenance therapy (MT) with the low-dose bacillus Calmette–Guérin (BCG) Tokyo strain. We investigated the efficacy and safety of MT with a half dose of the Tokyo strain for patients following transurethral resection of nonmuscle invasive bladder cancer (NMIBC). Methods This study retrospectively reviewed clinical data on 78 patients diagnosed with intermediate or high-risk NMIBC followed by either MT (n = 38) or IT alone (n = 40) between January 2012 and March 2018. Statistical analysis was performed to compare recurrence-free survival (RFS) and adverse effects between the two groups. BCG was instilled once weekly for 6 weeks as IT, then once weekly in 2-week for a total of 20 instillations over 3 years. Results Kaplan–Meier analyses showed that patients undergoing MT had significantly better RFS than did those undergoing IT alone (hazard ratio (HR):0.32, 95% confidence interval (CI):0.12–0.89, P = 0.02). The 3-year RFS was 65.0% in the IT group and 89.5% in the MT group. Multivariate analysis showed that MT was associated with a reduced risk of recurrence (HR: 0.32, 95% CI:0.11–0.93, P = 0.03). One MT patient (2.6%) exhibited progression. Conclusions The BCG Tokyo strain showed acceptable efficacy and safety in patients undergoing MT; thus, it is a potential treatment for preventing bladder cancer recurrence.

Outcomes and complications of Hyperthermic IntraVesical Chemotherapy using mitomycin C or epirubicin for patients with non-muscle invasive bladder cancer after bacillus Calmette-Guérin treatment failure. Cent European J Urol 2020; 73:287-294. [PMID: 33133655 PMCID: PMC7587473 DOI: 10.5173/ceju.2020.0148] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 07/07/2020] [Accepted: 07/16/2020] [Indexed: 12/02/2022] Open
Abstract
Introduction Chemohyperthermia is a feasible option in BCG (bacillus Calmette-Guérin) failure patients who desire bladder preservation. We aimed to assess outcomes and complications of chemohyperthermia using mitomycin C (MMC) or epirubicin (EPI). Material and methods From March 2017 to February 2020, 103 BCG failure or intolerance patients with high-risk NMIBC (non-muscle invasive bladder cancer) underwent a hyperthermic intravesical chemotherapy (HIVEC) regimen. Five patients did not complete at least 5 instillations and were excluded from analysis. MMC was used in 72 out of 98 patients (Group A) while EPI was used in 26 patients (Group B). Response to HIVEC, predictive factors for treatment outcome and the disease-free survival (DFS) were defined as primary endpoints. The complications of chemohyperthermia were assessed as a secondary endpoint. Results No significant differences were found in recurrence and progression after induction course between Groups A and B. Kaplan-Meier disease-free survival was 22.61 months in Group A and 21.93 in Group B. The log-rank test showed no statistically significant difference between the two curves (p = .627). In the multivariate analysis, patients with tumor size ≥3 cm (p = .029), recurrence rate >1/year (p = .034), concomitant carcinoma in situ (CIS) during transurethral resection of bladder (TURB) (p = .039) and BCG-unresponsive status (p = .048) were associated with a worse response to chemohyperthermia. The use of MMC or EPI did not influence the response to treatment (p = .157). A slightly significant higher rate of overall complications (p = .0488) was observed in Group B. A significantly higher rate of Grade 3 frequency/urgency (p = .0064) contributed to this difference. The use of EPI was the only independent factor associated with severe urinary frequency/urgency (p = .017). No patients experienced Grade 4/5 adverse events. Conclusions HIVEC can be considered a feasible option in BCG failure/intolerant NMIBC patients, avoiding or postponing radical cystectomy in some particular subclasses of patients.

Abstract
Background Urothelial cell carcinoma (UCC), also called transitional cell cancer, occurs significantly more often in males than in females. Essential for the prognosis of recovery is depth of infiltration (muscle-invasive or non-muscle invasive) and tumor-differentiation at initial diagnosis. The current study aimed to explore sex-related differences after initial diagnosis of UCC in Germany. Methods We identified patients who underwent transurethral resection of the bladder tumor (TUR-BT). Data were retrospectively analyzed, including TNM classification, histopathological grading, risk group according to the European Association of Urology (EAU), use of photody-namic diagnosis (PDD), and early intravesical chemotherapy (IVC). Results A total of 539 male and 190 female patients with UCC underwent TUR-BT. Approximately 75% were non-muscle invasive bladder cancer (NMIBC). Females evidenced significantly higher rates of muscle-invasive bladder cancer (MIBC; P=0.04). Carcinoma in situ (CIS) was significantly more common among males (P=0.01). Recurrence and progression rates showed no significant sex differences – only in the small subgroup of EAU low-risk NMIBC females, we found a significantly higher progression rate (P=0.03). In a Cox proportional hazards model, we found for MIBC, an HR for progression of 6.5 (95% CI, 1.29–33.2; P=0.02) after a median follow-up of 56 months. Use of PDD or IVC showed no significant differences in recurrence and progression between females and males. Conclusion Females were significantly more likely to suffer from MIBC at the time of first diagnosis. In NMIBC, males showed a significantly higher prevalence of CIS and EAU low-risk NMIBC females showed significantly higher rates of progression. Sex was not associated with recurrence rates in NMIBC. PDD and IVC were equally effective in both sexes. Based on the collected data we suggest to further investigate possible sex differences in UCC with therapeutical impact. Additional prospective multicenter studies are needed to evaluate both sex-related long-term disease courses and effectiveness of therapies.

Abstract
BACKGROUND Intravesical bacillus Calmette-Guerin (BCG) instillation is widely used as an adjuvant therapy after transurethral resection of bladder tumor (TURBT) in patients with intermediate- and high-risk nonmuscle invasive bladder cancer (NMIBC). However, the effective dose, duration, and strain of BCG have not yet been clearly determined. We aimed to elucidate the relationship between dose, duration, and strain of BCG and clinical outcomes in NMIBC patients treated with TURBT. METHODS We conducted a literature search in Embase, Scopus, and PubMed databases for all relevant articles published up to October 2016 in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. The relative risks of clinical outcomes, including recurrence, progression, cancer-specific mortality, and all-cause mortality according to dose (standard vs low), duration (induction vs maintenance), and strain of BCG were presented as the pooled risk ratio (RR) and 95% confidence interval (CI). RESULTS Nineteen studies meeting the inclusion criteria were finally selected in this meta-analysis. The risk of recurrence was significantly highly observed in case of low-dose BCG (RR, 1.17; 95% CI 1.06-1.30) and induction BCG (RR, 1.33; 95% CI 1.17-1.50) only group without heterogeneity among the included studies. Although there were no significant differences between dose or duration and other clinical outcomes. On direct comparison in each study comparing BCG strains, the Tice stain showed a relatively high probability of recurrence compared with the Connaught (RR, 1.29; 95% CI 1.01-1.64) and RIVM (RR, 2.04, 95% CI 1.28-3.25) strains. Funnel plot testing revealed no significant publication bias. CONCLUSION The use of standard dose and maintenance BCG instillation may be effective to reduce recurrence rate after TURBT for NMIBC. Further large scale, well-designed, and prospective studies, with stratification of the patients into risk group at randomization, will be required to determine the optimal guideline of BCG use to improve clinical outcomes in NMIBC.

Abstract
Bladder cancer is one of the most commonly diagnosed malignancies worldwide, derived from the urothelium of the urinary bladder and defined by long asymptomatic and atypical clinical picture. Its complex etiopathogenesis is dependent on numerous risk factors that can be divided into three distinct categories: genetic and molecular abnormalities, chemical or environmental exposure and previous genitourinary disorders and family history of different malignancies. Various genetic polymorphisms and microRNA might represent useful diagnostic or prognostic biomarkers. Genetic and molecular abnormalities - risk factors are represented by miRNA or genetic polymorphisms proved to be part of bladder carcinogenesis such as: genetic mutations of oncogenes TP53, Ras, Rb1 or p21 oncoproteins, cyclin D or genetic polymorhisms of XPD,ERCC1, CYP1B1, NQO1C609T, MDM2SNP309, CHEK2, ERCC6, NRF2, NQO1Pro187Ser polymorphism and microRNA (miR-143, −145, −222, −210, −10b, 576-3p). The aim of our article is to highlight the most recent acquisitions via molecular biomarkers (miRNAs and genetic polymorphisms) involved in bladder cancer in order to provide early diagnosis, precise therapy according to the molecular profile of bladder tumors, as well as to improve clinical outcome, survival rates and life quality of oncological patients. These molecular biomarkers play a key role in bladder carcinogenesis, clinical evolution, prognosis and therapeutic response and explain the molecular mechanisms involved in bladder carcinogenesis; they can also be selected as therapeutic targets in developing novel therapeutic strategies in bladder malignancies. Moreover, the purpose in defining these molecular non invasive biomarkers is also to develop non invasive screening programs in bladder malignancies with the result of decreasing bladder cancer incidence in risk population.
