Background: Immune checkpoint inhibitors (ICIs) are an important therapeutic pillar in metastatic urothelial carcinoma (mUC). The occurrence of immune-related adverse events (irAEs) appears to be associated with improved outcomes in observational studies. However, these associations are likely affected by immortal time bias and do not represent causal effects.

Background: Electronic patient-reported outcomes (ePROs) have been shown to enhance healthcare quality by improving patient symptom management or quality of life (QoL). However, ePROs data for urothelial cancer (UC) patients receiving systemic therapies are scarce, and the application of ePROs in this patient cohort may need specific setups. This study tested the feasibility of ePROs for UC patients receiving systemic therapies in the outpatient clinic of a tertiary care center.

Article Synopsis
  • - A study analyzed 131 patients with advanced metastatic urothelial cancer (mUC) who received systemic therapy between June 2017 and July 2021, focusing on the impact of immune checkpoint inhibitors (ICIs) on patient outcomes.
  • - Results showed a median overall survival of 24 months, with patients on ICIs for 6 months or more having a significantly higher median survival of 59 months; factors like metastatic sites and C-reactive protein levels influenced outcomes.
  • - The research highlights that over 60% of patients received second-line treatment, primarily with ICIs, indicating better patient prognosis with extended immunotherapy compared to historical data, despite limitations like the retrospective nature of the study.

Background: Treatment of muscle invasive bladder cancer can be challenging since treatment is associated with significant side effects and complication rates-especially in patients who often present with relevant comorbidities. In the metastatic stage, the purpose of treatment is palliation, although the oligometastatic stage takes a distinct role. At this stage, treatment of the primary tumor can play a role, if metastasis can be treated locally in addition to systemic treatment, especially the evolving drug treatment landscape could also change long holding paradigms in the near future.

Urothelial cancer (UC) is most commonly found in the urinary bladder, but can also appear in the upper urinary tract, where it is associated with several disease-specific challenges affecting its diagnosis, clinical staging, surgical management, and systemic therapy. A significant number of patients experience extra-vesical disease recurrence despite radical nephroureterectomy (RNU), leading to inevitable demise. Over the last years, the therapeutic armamentarium of UC has expanded with several systemic treatment options entering clinical care and deliver the potential to support a more individualized treatment in the near future.

We conducted a retrospective National Cancer Registry study in Austria to assess a possible seasonal variation in the clinical diagnosis of testicular germ cell tumors (TGCT). In total, 3615 testicular cancer diagnoses were identified during an 11-year period from 2008 to 2018. Rate ratios for the monthly number of TGCT diagnoses, as well as of seasons and half-years, were assessed using a quasi-Poisson model.

Purpose Of Review: Immune-checkpoint inhibitors (CPIs) have been implemented in the treatment algorithm of metastatic urothelial cancer as they have shown higher and more sustained responses compared with conventional second-line chemotherapy. Recently, several clinical trials have reported on CPIs in earlier disease stages such as muscle-invasive bladder cancer (MIBC). This review summarizes ongoing clinical trials and results from early phase clinical trials in muscle invasive and locally advanced bladder cancer.

Purpose Of Review: This review provides an overview of currently ongoing clinical trials evaluating the combination of immune checkpoint inhibitors (CPI) with other therapies in locally advanced or metastatic urothelial cancer and the rationale for this combination approach. We discuss the preliminary results from early data presented at recent meetings regarding the efficacy and safety of novel combination therapies including a CPI for metastatic urothelial cancer.

Recent Findings: CPI emerged as novel first-line or second-line treatment options in advanced and metastatic urothelial cancer (mUC).

Recent meta-analyses on checkpoint inhibitors in cancer report conflicting data regarding the association of patient gender with inhibitor efficacy. In advanced kidney cancer, checkpoint inhibitors have shown improved outcomes in first- and second-line settings compared with standard of care, but the role of patient gender on treatment outcome is unclear. We aimed to assess the efficacy of immunotherapy according to patient gender in advanced kidney cancer.

Purpose: We performed a retrospective analysis of patients treated with radical cystectomy and lymphadenectomy (LAD) for bladder cancer to assess the differential association of the extent of LAD with perioperative complications and re-hospitalization.

Materials And Methods: LAD templates were defined as limited (lLAD = external, internal iliac and obturator), extended (eLAD = up to crossing of ureter and presacral lymph nodes), and super-extended (sLAD = up to the inferior mesenteric artery). Logistic regression models investigated the association of LAD templates with intraoperative, 30- and 30-90-day postoperative complications, as well as re-hospitalizations within 30 and 30-90 days.
