CG0070 is a replication-competent oncolytic adenovirus that targets bladder tumor cells through their defective retinoblastoma pathway. Prior reports of intravesical CG0070 have shown promising activity in patients with high-grade non-muscle invasive bladder cancer (NMIBC) who previously did not respond to bacillus Calmette-Guérin (BCG). However, limited accrual has hindered analysis of efficacy, particularly for pathologic subsets. We evaluated interim results of a phase II trial for intravesical CG0070 in patients with BCG-unresponsive NMIBC who refused cystectomy. ⋯ This phase II study demonstrates that intravesical CG0070 yielded an overall 47% CR rate at 6 months for all patients and 50% for patients with CIS, with an acceptable level of toxicity for patients with high-risk BCG-unresponsive NMIBC. There is a particularly strong response and limited progression in patients with pure CIS.

Recent studies suggest that anesthetic technique during radical prostatectomy for prostate cancer may affect recurrence or progression. This association has previously been investigated in series that employ epidural analgesia. The objective of this study is to determine the association between the use of a multimodal analgesic approach incorporating paravertebral blocks and risk of biochemical recurrence following open radical prostatectomy. ⋯ Use of a multimodal analgesic approach incorporating paravertebral blocks is not associated with a reduced risk of biochemical recurrence following radical prostatectomy.

Risk of recurrent disease for men with clinical stage 1 high-risk nonseminomatous germ cell testicular cancer (CS1 NSGCT) with lymphovascular invasion (LVI) after orchiectomy is 50% and current treatment options (surveillance [S], retroperitoneal lymph node dissection [RPLND], or 1 cycle of BEP [BEP ×1]) are associated with a 99% disease specific survival, therefore practice patterns vary. We performed a decision analysis using updated data of long-term complications for men with CS1 NSGCT with LVI to quantify and assess relative treatment values. ⋯ We demonstrate that for surveillance to be superior to treatment with BEP ×1 or RPLND, the orchiectomy cure rate must be at least 82%, which is not expected in a patient population with high-risk CS1 NSGCT.

Clinical Trial Observational Study
Incidence and perioperative risk factors for early acute kidney injury after radical cystectomy and urinary diversion.
Early postoperative acute kidney injury (AKI) is associated with increased morbidity and mortality following major surgery. Only few reports exist on postoperative AKI and specifically its risk factors after radical cystectomy (RC) and urinary diversion (UD). We aimed to identify risk factors for AKI in patients undergoing RC and UD. ⋯ An increased risk for AKI was seen in patients with an operative time>400 minutes. Hence, in this group of patients the role of postoperative fluid management for preserving renal function should be considered. Further independent predictors of postoperative AKI were male sex, obesity, intraoperative blood loss, and a low preoperative plasma creatinine. So specially in male and obese patients, optimized perioperative nephroprotective strategies are of importance.

Conditional analyses of recurrence and progression in patients with TaG1 non-muscle-invasive bladder cancer.
To determine conditional recurrence-free survival (RFS) and progression-free survival (PFS) and improve decision-making toward surveillance protocols and scheduling. Furthermore, evaluating the evolution of predictors for disease recurrence over time, because TaG1 non-muscle-invasive bladder cancer harbors a risk of disease recurrence and progression. ⋯ Conditional-survival analyses demonstrates that the patient risk profile changes over time. RFS rates rise with increasing survival whereas PFS rates were stable. The impact of prognostic features decreases over time. Our findings can be used for patient counseling and planning of personalized follow-up.
