Around 7200 cases of Muscle Invasive Bladder Cancer are diagnosed annually in the Nordic countries combined. Muscle Invasive Bladder Cancer is an aggressive disease and it is linked with high mortality rates. The golden standard of treatment is radical cystectomy (RC) (the surgical removal of the bladder) and radical removal of lymph nodes in the pelvis. In addition to surgical treatment, and especially in cases where the tumour invades tissues surrounding the bladder or lymph nodes, chemotherapy is recommended. Chemotherapy can be administered before or after surgery, in a neoadjuvant (NAC) or adjuvant setting (AC). Although most patients recover well from surgery, there are significant risks regarding radical cystectomy. The greatest challenges in planning the treatment are making individual risk assessments and prognosis for the treated patients. Neoadjuvant chemotherapy is also insufficiently used and it is hard to predict how the tumour responds to chemotherapy. The purpose of this study is to collect prospective clinical data on radical cystectomy -patients in co-operation with other Nordic countries: Sweden, Denmark, Iceland and Norway. The collected data is used to validate existing prediction tools and discover novel tools for prediction of morbidity related to RC and prediction of oncological outcome after RC. The study is divided into three sub-studies. Transfusions during RC and the time of hospitalization after the surgery are associated poorer oncological outcome when compared to those patients who do not need transfusions. The third study focuses on the oncological outcomes in patients receiving blood transfusions. As there are some conflicting reports and the finding is not properly validated, we aim to validate the effect of transfusions on survival after RC. The number of transfusions during RC and the time between surgery and discharge from hospital will be recorded. Patient cohort will be divided into patients receiving transfusions and not receiving transfusion. The primary end point is patients receiving transfusion and its effect on cancer specific mortality at 24 months. For patients receiving NAC, additional secondary end-point is complete response (pT0N0) rate at RC.

The collected data is used to validate existing prediction tools and discover novel tools for prediction of morbidity related to RC and prediction of oncological outcome after RC. The study is divided into three sub-studies. The first sub-study is to validate low albumin levels as a predictor of complications after RC . The cut-off for low albumin has been <3,5 mg/l across the studies. This could be a very cost-effective biomarker but currently its relevance is limited by lack of proper prospective validation studies. The primary end-point in the Albumin sub-study is the 90-day major (Clavien Dindo 3-5) complication rate. The secondary end-points include total 90-day complication (Clavien 1-5) and 90-mortality rate (Clavien 5) for all patients and complication rate during NAC for patients receiving chemotherapy.

The collected data is used to validate existing prediction tools and discover novel tools for prediction of morbidity related to RC and prediction of oncological outcome after RC. The study is divided into three sub-studies. The second sub-study is on the preoperative neutrophil-lymphocyte ratio (NLR). Some studies suggest that NLR might be a predictor of oncological outcome of BC after RC. In addition, NLR has been suggested to correlate with NAC response and outcome after NAC and RC. The used cut-off value for NLR has varied between 2.26-3.0. Patients will be allocated into two groups: low NLR ratio (NLR<3), and high NLR ratio (NLR≥3). The lab test will be retrieved before RC at the time of routine clinical laboratory testing for all patients and also before the initiation of NAC for patients planned to have chemotherapy. The primary end-point is bladder-cancer specific survival and, and secondary endpoints include progression-free, and overall survival.
Patients with high-risk non-muscle invasive bladder cancer (NMIBC) are usually managed by transurethral resection of their bladder tumor (TURBT) alone plus additional intravesical therapy to deliver high local concentrations of a therapeutic agent within the bladder, potentially destroying viable tumor cells that remain following TURBT. Although the exact mechanism of bacillus Calmette-Guerin (BCG) antitumor action is unknown, its intravesical instillation triggers a variety of local immune responses, which appear to correlate with antitumor activity. BCG induction plus maintenance is the current, guideline-recommended standard of care for high-risk NMIBC. Both recent evidence and guidelines suggest that full-dose BCG maintenance after the first BCG dose of induction course as used in the SWOG 8507 and European Organization for Research and Treatment of Cancer (EORTC) 30911 and 30962 trials, is the most appropriate maintenance schedule. High-risk NMIBC patients following adequate treatment have a recurrence rate at 1 and 2 years of 25 and 30% respectively after treatment with the current standard (BCG), which is clearly unsatisfactory. Programmed death ligand 1 (PD-L1) is a surface glycoprotein that functions as an inhibitor of T-cells and plays a crucial role in suppression of cellular immune response. It is implicated in tumor immune escape by inducing apoptosis of activated antigen-specific CD8 T-cells, impairing cytokine production and diminishing the toxicity of activated T-cells. PD-L1 expression by immunohistochemistry using the Ventana SP142 assay on tumor-infiltrating immune cell (IC) status defined by the percentage of PD-L1 positive ICs: IC0 (<1%); IC1 (≥1% but<5%); and IC2/3 (≥5%PD-L1) has been demonstrated to be higher (IC2/3) in resection and TURBT specimens versus biopsies from primary lesions or metastatic sites. In patients with metastatic bladder cancer, treatment with the PD-L1 inhibitor atezolizumab (1200 mg, every 3 weeks) resulted in objective response rates of 26% in the IC2/3 group, 18% in the IC1/2/3 group and 15% in all patients. The median overall survival was 11.4 months in the IC2/3 group, 8.8 months in the IC1/2/3, and 7.9 months in all patients. Grade 3-4 related treatment-related adverse events occurred in 16% and grade 3-4 immune-mediated adverse events occurred in 5% of treated patients. In murine models with invasive bladder cancer, anti-PD-1 plus CpG has shown to increase survival in mice, with anti-PD-1 plus CpG being superior to either agent alone. Taken together, these results confirmed the clinical activity of atezolizumab in metastatic bladder cancer, which could be beneficial in patients with NMIBC in combination with standard approaches such as BCG.
This is a pilot study that involves human subjects undergoing cystectomy surgery for bladder cancer, testing the utilization of a mobile health app that promotes postoperative patient engagement, along with provider monitoring and care. The aim of this pilot study is to assess feasibility and acceptability of an Internet-based mobile health tool following cystectomy discharge. Objectives will be met by assessing weekly adherence, determining acceptability of mobile health questions post-surgery by patients and providers, and by obtaining participant feedback regarding the tool. Complications, re-admissions, and resource utilization will also be monitored throughout the study. The hypothesis is that an mobile health intervention that tracks PROs, provides educational content, and allows real-time feedback via internet-enabled devices has the potential to improve the quality of care delivery and overall patient experience following surgery by decreasing resource utilization and improving symptom control and communication.
A multicenter Phase 1b/2, two stage, open label study of MMC/Capecitabine ChRT combined with nivolumab monotherapy or nivolumab and ipilimumab combination therapy in adult (>18 years) subjects with non-metastatic muscle invasive bladder cancer that qualify for ChRT with curative intent.
Combined-modality treatment of localized muscle invasive bladder cancer including transurethral resection (TUR), radiotherapy and dual checkpoint inhibition immunotherapy could achieve pathological complete response in some patients. These patients could avoid to undergone radical surgery with radical cystectomy and preserve their bladder, without the side-effects associated with chemotherapy and surgery. This study has been design to determine the efficacy of durvalumab plus tremelimumab with concurrent radiotherapy in terms of pathological response rate in patients with localized muscle invasive bladder cancer treated with bladder preservation intent.
This is a non-randomized, non-blinded, pilot study administering hyperthermic intraperitoneal chemotherapy with Mitomycin-C in 10 men and women with muscle-invasive urothelial carcinoma of the bladder undergoing radical cystectomy with pelvic lymph node dissection who have risk factors for tumor recurrence.
This is a pilot study of avelumab in patients with non-metastatic, muscle invasive bladder cancer who are eligible for radical cystectomy (RC), but are ineligible for cisplatin based neoadjuvant therapy. The target recruitment is 10 evaluable patients for this window of opportunity study. Pre- and post-treatment tumor samples from transurethral resection of the bladder tumor and RC will be used for study endpoints.
