BACKGROUND AND OBJECTIVE: Therapeutic options for patients with non-muscle-invasive bladder cancer (NMIBC) have traditionally been limited to intravesical immunotherapy or chemotherapy. A considerable number of new options have been investigated in recent years. Our aim was to review the efficacy and toxicity of novel therapeutic options (results already reported or currently under investigation) for patients with NMIBC. METHODS: We assessed the efficacy of various novel therapeutic options by examining key endpoints in diverse settings, including recurrence, progression, overall survival, disease-specific survival, and complete response. We identified the principal advantages and limitations for each option. Safety was predominantly evaluated as the incidence of grade ≥3 adverse events. Our investigation focused on evidence from scientific articles and congress abstracts published in English within the past 5 yr. KEY FINDINGS AND LIMITATIONS: To date, pembrolizumab, nadofaragene firadenovec, and the combination of BCG with N-803 have received US Food and Drug administration approval for the treatment of BCG-unresponsive carcinoma in situ of the bladder (with or without papillary tumours). Five phase 3 trials are recruiting BCG-naïve patients with high-risk NMIBC. There is increasing interest in an ablative rather than an adjuvant approach for patients with intermediate-risk NMIBC. CONCLUSIONS AND CLINICAL IMPLICATIONS: Novel drugs and device-assisted drug delivery systems are on the verge of changing the treatment of NMIBC. Novel intravesical options seem to have the same efficacy with fewer adverse events in comparison to systemic therapies. PATIENT SUMMARY: We reviewed new therapy options for non-muscle-invasive bladder cancer. Two agents (pembrolizumab and nadofaragene firadenovec) have been approved to date. Ongoing trials are assessing direct delivery of drugs in solution into the bladder. This route seems to have similar efficacy and fewer side effects than intravenous immunotherapy.
OBJECTIVES: Insulin-like growth factor-I and its binding proteins are involved in cancer development, progression, and metastasis. In urothelial carcinoma, the impact of this pathway is still poorly investigated. The present large cohort study aimed to evaluate the association of preoperative circulating levels of insulin-like growth factor-I, insulin-like growth factor-I binding protein-2 and -3 on outcomes after radical cystectomy. METHODS: A retrospective cohort study of the plasma specimens from 1036 consecutive urothelial carcinoma patients who were treated with radical cystectomy. The primary and secondary outcomes were adverse histopathological features and survival outcomes. Binominal logistic regression and multivariable Cox regression analyses were performed to assess the association of plasma levels of insulin-like growth factor-I, insulin-like growth factor-I binding protein-2 and -3 with outcomes. RESULTS: On multivariable analysis adjusting for the effects of preoperative variables, lower insulin-like growth factor-I binding protein-2 levels were associated with an increased risk of lymph node metastasis and (any non-organ confined disease) any non-organ confined disease. Insulin-like growth factor-I binding protein-3 levels were also inversely independently associated with lymph node metastasis. Receiver operating characteristic curve analysis showed that the addition of insulin-like growth factor-I binding proteins biomarkers to a reference model significantly improved the discriminating ability for the prediction of lymph node metastasis (+10.0%, P < 0.001). On multivariable Cox regression models, lower levels of both insulin-like growth factor-I binding protein-2 and -3 plasma levels were associated with recurrence-free survival, cancer-specific survival, and overall survival. insulin-like growth factor-I binding protein-2 and -3 levels and improved the discrimination of a standard reference model for the prediction of recurrence-free survival, cancer-specific survival, and overall survival (+4.9%, 4.9%, 2.3%, respectively). CONCLUSIONS: Preoperative insulin-like growth factor-I binding protein-2 and -3 are significantly associated with features of biologically and clinically aggressive urothelial carcinoma. These biomarkers improved prognostic urothelial carcinoma models.

CONTEXT: The European Association of Urology (EAU) Guidelines Panel on Upper Urinary Tract Urothelial Carcinoma (UTUC) has prepared updated guidelines to aid clinicians in the current evidence-based management of UTUC and to incorporate recommendations into clinical practice. OBJECTIVE: To provide an overview of the EAU guidelines on UTUC as an aid to clinicians. EVIDENCE ACQUISITION: The recommendations provided in the current guidelines are based on a thorough review of available UTUC guidelines and articles identified following a systematic search of Medline. Data on urothelial malignancies and UTUC were searched using the following keywords: urinary tract cancer, urothelial carcinomas, upper urinary tract carcinoma, renal pelvis, ureter, bladder cancer, chemotherapy, ureteroscopy, nephroureterectomy, neoplasm, adjuvant treatment, instillation, recurrence, risk factors, and survival. References were weighted by a panel of experts. EVIDENCE SYNTHESIS: Owing to the rarity of UTUC, there are insufficient data to provide strong recommendations. The 2017 tumour, node, metastasis (TNM) classification is recommended. Recommendations are given for diagnosis and risk stratification as well as for radical and conservative treatment, and prognostic factors are discussed. A single postoperative dose of intravesical mitomycin after nephroureterectomy reduces the risk of bladder tumour recurrence. Kidney-sparing management should be offered as a primary treatment option to patients with low-risk tumour and two functional kidneys. After radical nephroureterectomy, cisplatin-based chemotherapy is indicated in locally advanced UTUC. CONCLUSIONS: These guidelines contain information on the management of individual patients according to a current standardised approach. Urologists should take into account the specific clinical characteristics of each patient when determining the optimal treatment regimen, based on the proposed risk stratification of these tumours. PATIENT SUMMARY: Urothelial carcinoma of the upper urinary tract is rare, but because 60% of these tumours are invasive at diagnosis, an appropriate diagnosis is most important. A number of known risk factors exist.
Bacillus Calmette-Guérin (BCG) is the most widely used vaccine worldwide and has been used to prevent tuberculosis for a century. BCG also stimulates an anti-tumour immune response, which urologists have harnessed for the treatment of non-muscle-invasive bladder cancer. A growing body of evidence indicates that BCG offers protection against various non-mycobacterial and viral infections. The non-specific effects of BCG occur via the induction of trained immunity and form the basis for the hypothesis that BCG vaccination could be used to protect against the severity of coronavirus disease 2019 (COVID-19). This Perspective article highlights key milestones in the 100-year history of BCG and projects its potential role in the COVID-19 pandemic.

Transurethral resection of bladder tumour is the initial, most critical step in the management of bladder cancer; as such, this is a call to arms for the urological community to it the due diligence it deserves regarding technology and training.
