AbstractBladder cancer is the most frequent malignancy of the urinary system and is ranked the seventh most diagnosed cancer in men worldwide. About 70-75% of all newly diagnosed patients with bladder cancer will present disease confined to the mucosa or submucosa, the non-muscle invasive bladder cancer (NMIBC) subtype. Of those, approximately 70% will recur after transurethral resection (TUR). Due to this high rate of recurrence, patients are submitted to an intensive follow-up program that should be maintained throughout many years, or even throughout life, resulting in an expensive follow-up, with cystoscopy being the most cost-effective procedure for NMIBC screening. Currently, the gold standard procedure for detection and follow-up of NMIBC is based on the association of cystoscopy and urine cytology. As cystoscopy is a very invasive approach, over the years, many different non-invasive (both in serum and urine samples) assays have been developed in order to search genetic and protein alterations related to the development, progression and recurrence of bladder cancer.TERTpromoter mutations andFGFR3hotspot mutations are the most frequent somatic alterations in bladder cancer and constitute the most reliable biomarkers for bladder cancer. Based on these findings, an ultra-sensitive assay called Uromonitor®was developed that corresponds to a urine-based assay capable of detecting trace amounts of the two most common alterations in NMIBC,TERTpromoter andFGFR3mutation, in urine samples. The Uromonitor®test was performed in a cohort of 72 patients, firstly diagnosed with bladder cancer and under surveillance for NMIBC, to access its sensitivity and specificity in the detection of NMIBC recurrence. Uromonitor®was shown to be highly sensitive and specific in detecting recurrence of bladder cancer in patients under surveillance of non-muscle invasive bladder cancer.

Patients with non-muscle invasive bladder cancer (NMIBC) undergo lifelong monitoring based on repeated cystoscopy and urinary cytology due to the high recurrence rate of this tumor. Nevertheless, these techniques have some drawbacks, namely, low accuracy in detection of low-grade tumors, omission of pre-neoplastic lesions and carcinomas in situ (CIS), invasiveness, and high costs. This work aims to identify a urinary metabolomic signature of recurrence by proton Nuclear Magnetic Resonance (1H NMR) spectroscopy for the follow-up of NMIBC patients. To do this, changes in the urinary metabolome before and after transurethral resection (TUR) of tumors are analyzed and a Partial Least Square Discriminant Analysis (PLS-DA) model is developed. The usefulness of this discriminant model for the detection of tumor recurrences is assessed using a cohort of patients undergoing monitoring. The trajectories of the metabolomic profile in the follow-up period provide a negative predictive value of 92.7% in the sample classification. Pathway analyses show taurine, alanine, aspartate, glutamate, and phenylalanine perturbed metabolism associated with NMIBC. These results highlight the potential of 1H NMR metabolomics to detect bladder cancer (BC) recurrences through a non-invasive approach.

Introduction: BCG and MMC shortage and Covid-19 pandemic, more recently, limit accessibility to maintenance regimen in intravesical prophylaxis against recurrence of non-muscle invasive bladder cancer (NMIBC). Ellagic acid (EA) and Annona muricata (AM) exert antitumor activity against different human tumours. An observational prospective study on the prophylactic effect of oral administration of EA+AM in patients avoiding maintenance regimen is presented. Materials and methods: Patients affected by NMIBC and not undergoing maintenance after a 6-week course of intravesical prophylaxis with MMC or BCG were entered. Tis and very high-risk tumours were excluded. After informed consent, the patients were subdivided in relation to the oral assumption or not of EA (100 mg) plus AM (100 mg), daily for 6 months. All patients were submitted to 3-month cytology and cystoscopy. Results: 162 (90%) of 180 entered patients are evaluable, 90 and 72 receiving or not EA+AM. No difference emerged in patients’ characteristics between the two groups. BCG was given in 86 (54%) and chemotherapy in 74 (46%) patients. The recurrence free rate at 3, 6 and 12 months in patients assuming or not EA was 96.5% versus 84.6% ( p = 0.003), 85.4% versus 64.8% ( p = 0.005) and 74.2% versus 60.6% ( p = 0.246), respectively. The recurrence free survival at 12 months in patients assuming or not EA was 63.0% versus 34.5% ( p < 0.0001). Discussion and conclusions: Our study suffers several limits: not randomized trial although prospective, limited number of patients and short follow-up, nevertheless it shows the prophylactic effect of oral EA+AM in absence of maintenance after intravesical chemotherapy or immunotherapy induction.

Background&amp;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 (&gt; 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.
