A high body mass index (BMI) is associated with an increased risk for developing renal cell carcinoma (RCC), a higher complication rate after surgery, and a postoperative decline in renal function after nephrectomy. In contrast, a high preoperative BMI has been associated with increased survival in patients with localized RCC. We examined the prognostic impact of the BMI in patients treated for metastatic RCC (mRCC) in daily routine practice in Germany. ⋯ Our analysis showed a significant and independent correlation of a high BMI with longer OS in a prospective German cohort of mRCC routine patients starting first-line systemic treatment.

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.

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.

Previous studies have suggested a link between metabolic syndrome (MetS) and prostate cancer (PCa). In the present study, we aimed to assess the association between MetS and markers of PCa aggressiveness on radical prostatectomy (RP). ⋯ MetS was an independent predictive factor for higher ISUP group and positive margins at RP. Low HDL-cholesterol alone, and having 4 and more MetS components were also associated with higher risk of adverse pathological features.

Multicenter Study Comparative Study
A prospective study of health-related quality-of-life outcomes for patients with low-risk prostate cancer managed by active surveillance or radiation therapy.
Patients with low-risk prostate cancer (PCa) often have excellent oncologic outcomes. However, treatment with curative intent can lead to decrements in health-related quality of life (HRQoL). Patients treated with radical prostatectomy have been shown to suffer declines in urinary and sexual HRQoL as compared to those managed with active surveillance (AS). Similarly, patients treated with external-beam radiation therapy (EBRT) are hypothesized to experience greater declines in bowel HRQoL. As health-related quality-of-life (HRQoL) concerns are paramount when selecting among treatment options for low-risk PCa, this study examined HRQoL outcomes in men undergoing EBRT as compared to AS in a prospective, racially diverse cohort. ⋯ Patients receiving EBRT for low-risk prostate cancer suffer declines in bowel HRQoL. These declines are not experienced by patients on AS, suggesting that management of low-risk prostate cancer with AS may offer a means for preserving HRQoL following prostate cancer diagnosis.
