- 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: To overview the updated Swedish National Guidelines on Urothelial Carcinoma 2021, with emphasis on non-muscle-invasive bladder cancer (NMIBC) and upper tract urothelial carcinoma (UTUC). Methods: A narrative review of the updated version of the Swedish National Guidelines on Urothelial Carcinoma 2021 and highlighting new treatment recommendations, with comparison to the European Association of Urology (EAU) guidelines and current literature. Results: For NMIBC the new EAU 2021 risk group stratification has been introduced for non-muscle invasive bladder cancer to predict risk of progression and the web-based application has been translated to Swedish (https://nmibc.net.). For patients with non-BCG -responsive disease treatment recommendations have been pinpointed, to guide patient counselling in this clinical situation. A new recommendation in the current version of the guidelines is the introduction of four courses of adjuvant platinum-based chemotherapy to patients with advanced disease in the nephroureterectomy specimen (pT2 or higher and/or N+). Patients with papillary urothelial neoplasms with low malignant potential (PUNLMP) can be discharged from follow-up already after 3 years based on a very low subsequent risk of further recurrences. Conclusions: The current version of the Swedish national guidelines introduces a new risk-stratification model and follow-up recommendation for NMIBC and adjuvant chemotherapy after radical surgery for UTUC.
