- This retrospective real-world study shows that vinflunine and platinum-combinations were the most common regimens after previous pembrolizumab in patients with metastatic urothelial cancer (mUC). The median progression-free and overall survival were 3.3 and 7.7 months respectively. Conventional chemotherapy after immunotherapy may remain to be a late-stage treatment option for selected patients in the era of targeted precision medicine of mUC. Background: Immune checkpoint inhibitors (ICIs) have been established as a routine treatment in patients with metastatic urothelial cancer (mUC). However, there has been no standard of care after progression on ICIs. We investigated real-world treatment patterns and efficacy of chemotherapy (CHT) after pembrolizumab, in the era before introduction of maintenance avelumab and antibody-drug conjugates (ADC). Patients and Methods: An observational, retrospective study was conducted at twelve Nordic centers. Patients with mUC were treated according to investigator s ' choice of CHT after pembrolizumab. Primary endpoint was overall response (ORR) and disease control rate (DCR); secondary endpoints were progression-free (PFS) and overall survival (OS). Results: In total, 102 patients were included whereof 23 patients received CHT after pembrolizumab as second line treatment (subcohort A) and 79 patients in third line (subcohort B). Platinum-gemcitabine combinations were the most common regimens in subcohort A, and vinflunine in subcohort B. The ORR and DCR were 36% and 47%, respectively. Presence of liver metastases was independently associated with lower ORR and DCR. The PFS and OS were 3.3 months and 7.7 months, respectively. Eastern Cooperative Oncology Group Performance Status (ECOG PS) and number of previous cycles of pembrolizumab were found to be independent prognostic factors associated with OS. Conclusion: In a real-world setting, CHT showed clinically

- Objective The incidence of benign ureteroenteric strictures following radical cystectomy (RC) for urinary bladder cancer (UBC) is investigated mainly in single-centre studies from high-volume centres. The aim of this study was to evaluate the cumulative incidence of strictures and risk factors in a population-based cohort. Patients and methods Data was collected from Bladder Cancer Data Base Sweden (BladderBaSe). The primary endpoint was stricture with intervention. Secondary endpoint included hydronephrosis both with/without intervention. Results In total, 5,816 patients were registered as having had RC due to UBC between 1997 and 2014. After a median follow-up of 23.5 months (IQR = 9.0-63.1 months; range = 0.0-214.0 months), we found that 515 (8.9%) patients underwent intervention for stricture. Seven hundred and sixty-one (13.1%) patients were diagnosed with hydronephrosis without intervention. The cumulative incidence of strictures with intervention was 19.7% (95% CI = 16.7-23.1%) during the 17 years of follow-up. In the first year, the cumulative incidence of strictures was 5.6% (95% CI = 5.0-6.2%), and in the first 2 years 8.4% (95% CI = 7.6-9.3%). For the secondary endpoint, the cumulative incidence was 30.4% (95% CI = 26.7-33.1%) after 17 years. Only the year of RC was associated with stricture incidence in Cox regression analysis, whereas hospital cystectomy volume, patient age and patient sex were not. Conclusion Ureteroenteric strictures requiring intervention may be more common than previously reported, affecting nearly one fifth of patients who have undergone RC for UBC. The annual incidence was highest in the first 2 years after surgery but the cumulative incidence increased continuously during 17 years of follow-up.
