    Abstract Cisplatin-based chemotherapy has been the standard of care in metastatic urothelial cancer (mUC) for more than two decades. However, many patients with comorbidities cannot receive cisplatin or its alternative, carboplatin. 'Cisplatin-ineligible' and 'platinum-ineligible' patients lacked effective therapy options. However, the recent combination of enfortumab vedotin (EV), an antibody-drug conjugate targeting Nectin-4, with pembrolizumab (P), an antibody targeting the programmed death-1 (PD-1) immune checkpoint, is changing the status quo of frontline mUC treatment, with potential synergy seen in the EV-103 and EV-302 clinical trials. First, we review the working definitions of 'cisplatin ineligibility' and 'platinum ineligibility' in mUC clinical trials and the standard of care in both categories. Then, we review select clinical trials for frontline treatment of cisplatin- and platinum-ineligible mUC patients on ClinicalTrials.gov. We classify the investigated drugs in these trials by their therapeutic strategies. Alongside chemotherapy combinations, the field is witnessing more immunotherapy combinations with fibroblast growth factor receptor (FGFR) inhibitors, bicycle toxin conjugates, bispecific antibodies, innovative targeted therapies, and many others. Most importantly, we rethink the value of classifying patients by cisplatin or platinum ineligibility in the frontline setting in the post-EVP era. Lastly, we discuss new priority goals to tailor predictive, monitoring, and prognostic biomarkers to these emergent therapies.

    Abstract The coronavirus disease 2019 (COVID-19) pandemic is posing insurmountable challenges to healthcare systems globally. Cancer therapy is complex, and outcomes are centered on timing. Many oncology societies and health ministries have issued guidelines for cancer care to enable oncologists and patients to navigate the crisis. Lessons learned should inform care models for future pandemics.

    Abstract Abstract: Antibody-drug conjugates (ADCs) have joined the armamentarium against urothelial cancer (UC) as an effective therapy option. Since 2019, the US Food and Drug Administration has approved 2 ADCs for advanced previously treated UC: enfortumab vedotin, which targets nectin-4 and sacituzumab govitecan, which targets trophoblast cell-surface antigen 2. These ADCs are now being tested in earlier disease settings and in previously untreated patients. Furthermore, novel ADCs (e.g., anti-HER-2) are being tested in the clinic and show promising clinical benefit. The next frontier is to understand the mechanisms of resistance and response, gaining experience with ADC-related adverse events and learning the best strategy to sequence and combine these agents with existing therapies. Here, we highlight the recent advances in the development of ADCs for treating localized and metastatic UC.

    Abstract Background: Combining immune checkpoint therapy (ICT) and vascular endothelial growth factor inhibitors (VEGFi) may result in increased treatment-related and immune-related adverse events (TRAEs and irAEs) compared to ICT alone. This metanalysis was conducted to identify prospective phase II or III clinical studies that evaluated the toxicity profile of ICT + VEGFi compared to ICT alone.
    Methods: A systematic search was performed across all cancer types and major databases until August 10, 2022, and screening was done by two independent investigators. Inclusion criteria included phase 2 or 3 studies with at least one arm of patients treated with combination therapy and one arm treated with monotherapy. Adverse event data were pooled using a restricted maximum likelihood fixed effects model, and heterogeneity using Cochran's Q (chi-square) test.
    Results: 7 out of 9366 studies met the inclusion criteria, and 808 and 927 patients were treated with ICT monotherapy and a combination of ICT with VEGFi, respectively. Only one study reported irAEs, so the analysis was restricted to TRAEs. The total number of TRAEs was significantly higher in the ICT + VEGFi group (RR:1.49; 95% CI 1.37 -1.62; p=1.5×10-21), and more frequent treatment withdrawals were attributed to TRAEs (RR:3.10; 95% CI 1.12-8.59; p=0.029). The highest TRAE effect size increases noted for rash (RR 6.50; 95% CI 3.76 - 11.25; p=2.1×10-11), hypertension (RR:6.07; 95% CI 3.69-10.00; p=1.3×10-12), hypothyroidism (RR:5.02; 95% CI 3.08 - 8.19; p=8.9×10-11), and diarrhea (RR:4.94; 95% CI 3.21-7.62; p=3.8×10-13). Other significantly more frequent TRAEs included nausea, anemia, anorexia, and proteinuria.
    Conclusion: Combination therapy with ICT and VEGFi carries a higher risk of certain TRAEs, such as rash, hypertension, hypothyroidism, diarrhea, nausea, anorexia, and proteinuria, compared to ICT monotherapy. More granular details on the cause of AEs, particularly irAEs, should be provided in future trials of such regimens.

    Abstract Introduction Anesthesia is an important specialty in the medical field responsible for caring for patients before, during, and after operations. It involves monitoring vital signs, managing pain levels, and regulating consciousness. There are various subspecialties of anesthesia, including general anesthesia, intensive care medicine, cardiac anesthesia, and pain medicine, among others. This study aims to assess and evaluate the knowledge and perceptions of medical students regarding the role of anesthesiologists and the factors influencing their career choices. Methods A descriptive cross-sectional study was conducted with 379 clinical-year medical students from colleges of medicine across Saudi Arabia. An online questionnaire consisting of 26 items was distributed among the medical students. The questionnaire included sociodemographic characteristics, factors influencing the choice of a career in anesthesiology, and perceptions related to the role of anesthesia. Statistical analysis was performed using RStudio [R Core Team (2021), R version 4.3.1, R Foundation for Statistical Computing, Vienna, Austria]. Categorical variables were presented using frequencies and percentages, while numerical variables were expressed using the median and interquartile ranges (IQRs). Results Among the 379 clinical-year medical students surveyed, a majority of participants (59.6%) reported undergoing a mandatory rotation in anesthesia during their fifth or sixth (final) year of medical school. It is noteworthy that good knowledge was significantly associated with having a mandatory rotation in anesthesia during the fifth or sixth year, with 96.0% of students who had a mandatory rotation demonstrating good knowledge, compared to 88.2% of those who did not. A smaller proportion (1.3%) opted for an elective anesthesia rotation during this period. Among those who undertook an elective clinical rotation in anesthesia, all respondents (100.0%) reported undertaking the elective rotation for three weeks or more and stated that this rotation inspired them to pursue a career in anesthesia. Regarding the factors influencing the choice of residency programs, a controllable lifestyle, particularly the ability to control work hours, emerged as the most influential factor, with 96.8% of participants considering it as such. This was followed by income (91.6%), the presence of a doctor-patient relationship (72.6%), and the prestige of the specialty (69.7%). Conclusion The medical students demonstrated reasonably good knowledge of the anesthesiologist's role, which can be attributed, in part, to the mandatory rotation in anesthesia. In terms of factors influencing career choice, a good lifestyle was found to be the most influential, followed by income, the doctor-patient relationship, and the prestige of the specialty.

    Abstract Purpose of review: Bladder cancer is the 12th most common cancer worldwide. Historically, the systemic management of urothelial carcinoma has been confined to platinum-based chemotherapy. In this review, we discuss the evolving landscape of systemic treatment for urothelial carcinoma.
    Recent findings: Since 2016, when the Food and Drug Administration approved the first immune checkpoint inhibitor (CPI), programmed cell death 1 and programmed cell death ligand 1 inhibitors have been evaluated in the nonmuscle invasive bladder cancer, localized muscle invasive bladder cancer as well as advanced/metastatic bladder cancer settings. Newer approved treatments such as fibroblast growth factor receptor (FGFR) inhibitors and antibody-drug conjugates (ADCs) represent second-line and third-line options. These novel treatments are now being assessed in combination as well as with older traditional platinum-based chemotherapy.
    Summary: Novel therapies continue to improve bladder cancer outcomes. Personalized approach with well validated biomarkers are important to predict response to therapy.
