Background&Aim: High grade non-muscle invasive bladder cancer (NMIBC) is common in urological practice. Most of these cancers are or become refractory to intravesical immunotherapy and chemotherapy. Here we evaluated the efficacy of combined local bladder hyperthermia and intravesical mitomycin-C (MMC) instillation in patients with high-risk recurrent NMIBC. Materials and methods: Between February 2014 and December 2015, 18 patients with high risk NMIBC were enrolled. Patients were treated in an outpatient basis with 6 weekly induction sessions followed by monthly maintenance sessions with intravesical MMC in local hyperthermia with bladder wall thermo-chemotherapy (BWT) system (PelvixTT system, Elmedical Ltd., Hod Hasharon, Israel). The follow-up regimen included cystoscopy after the induction cycle and thereafter with regular intervals. Time to disease recurrence was defined as time from the first intravesical treatment to endoscopic or histological documentation of a new bladder tumour. Adverse events were recorded according to CTC 4.0 (Common Toxicity Criteria) score system. Results: Mean age was 72 (32-87) years. 10 patients had multifocal disease, 9 had CIS, 6 had recurrent disease and 2 had highly recurrent disease (> 3 recurrences in a 24 months period). 6 patients underwent previous intravesical chemotherapy with MMC. The average number of maintenance sessions per patient was 7.6. After a mean follow-up of 433 days, 15 patients (83.3%) were recurrence-free. 3 patients had tumour recurrence after a mean period of 248 days without progression. Side effects were limited to grade 1 in 2 patients and grade 2 in 1 patient. Conclusions: BWT seems to be feasible and safe in high grade NMIBC. More studies are needed to identify the subgroup of patients who may benefit more from this treatment.

Background: Mast cells play a critical role in tumor-associated immune pathways. We aimed to determine whether the urinary mast cell mediators predict the immune response in patients with non-muscle invasive bladder cancer (NMIBC) treated with Bacillus Calmette-Guérin (BCG) immunotherapy. Methods: Nineteen patients who have received immunotherapy due to NMIBC and 19 healthy participants were enrolled. Urine samples were collected to assay N-methylhistamine, histamine, and tryptase levels immediately before the first BCG instillation, immediately after the third and sixth instillations, and four weeks after the sixth instillation in patients with NMIBC and at a single visit in healthy participants. Cystoscopic examinations were performed on the patient with NMIBC at three-month intervals for two years. The changes in urinary markers due to BCC response, BCG instillation, and the presence of NMIBC were assessed. Results: The average age was 56.1 ± 10.5 years in patients with NMIBC. Fourteen patients had high-grade Ta tumors, and 5 had high-grade T1 tumors. While 12 patients responded, 6 presented with recurrence and 1 with progression. There was no correlation between the levels of mast cell mediators and BCG response. The N-methylhistamine and histamine levels were increased significantly with the onset of immunotherapy, and N-methylhistamine levels were significantly decreased when immunotherapy was terminated. Pre-BCG estimated marginal means of N-methylhistamine were significantly higher in patients with NMIBC than healthy participants. Conclusions: Our study is the first study to identify the changes in mast cell mediators with the onset of immunotherapy and with the presence of bladder cancer. However, these mediators were not found to predict the patients’ response to immunotherapy.

BACKGROUND: Mini Chromosome Maintenance 5 (MCM5) is considered as a urinary biomarker of bladder cancer. ADXBLADDER is a commercially available test to detect MCM5 antibodies. OBJECTIVE: External validation of ADXBLADDER test as a urinary biomarker of histopathologically confirmed non-muscle invasive bladder cancer (NMIBC) recurrence. METHODS: The study enrolled 119 consecutive patients with a history of NMIBC and 37 healthy volunteers matched as controls. Single, full-void urine samples were collected from patients before cystoscopy ± TUR. To measure MCM5 expression, Arquer Diagnostics ADXBLADDER test was used. The study protocol was registered within the clinical trials database (NCT03796299). RESULTS: Among patients with NMIBC history, recurrence was diagnosed in 83 patients (69.7%). ADXBLADDER demonstrated sensitivity of 73.5% (95% confidence interval (CI) 62.7%–82.6%), specificity of 33.3% (95% CI 18.6% to 51%), overall negative predictive value (NPV) of 35.3% (95% CI 23.3% to 49.5%) and overall positive predictive value of 71.8% (95% CI 66.1% to 76.8%) for detecting recurrence. In a control group, false positive ADXBLADDER results were noticed in 18 patients (48.6%). The sensitivity and NPV were the highest in invasive tumors (100% and 100%, respectively) and in high-grade recurrences (81.8% and 94.1%, respectively). CONCLUSIONS: ADXBLADDER has a moderate sensitivity and poor specificity in detecting NMIBC recurrence. However, it properly diagnoses patients with T1+ stage recurrence or high-grade tumors.
