Review Meta Analysis
Laparoscopic versus open nephroureterectomy for the treatment of upper urinary tract urothelial carcinoma: a systematic review and cumulative analysis of comparative studies.
Laparoscopic nephroureterectomy (LNU) has increasingly been used as a minimally invasive alternative to open nephroureterectomy (ONU), but studies comparing the efficacy and safety of the two surgical procedures are still limited. ⋯ Our data suggest that LNU offers reliable perioperative safety and comparable oncologic efficacy when compared to ONU. Given that some limitations cannot be overcome, well-designed prospective trials are needed to confirm our findings.

Characterising responders to neoadjuvant chemotherapy (NAC) is important to minimise overtreatment and the unnecessary delay of definitive treatment of urothelial urinary bladder cancer. ⋯ Survival benefits of NAC are reflected in downstaging of the primary tumour. Chemo-induced downstaging might be a potential surrogate marker for OS.

Randomized Controlled Trial
Infectious complications and hospital admissions after prostate biopsy in a European randomized trial.
The complications of prostate needle biopsy (PNB) are important when considering the benefits and harms of prostate cancer screening. Studies from the United States and Canada have recently reported increasing numbers of hospitalizations for infectious complications after PNB. ⋯ In a European screening trial, <5% PNBs resulted in febrile complications. Significant risk factors included diabetes and prostatic enlargement. Although most fevers were managed on an outpatient basis, infection remained the leading cause of hospital admission after PNB. Consistent with prior international reports, the frequency of hospital admissions after PNB significantly increased over time. Nevertheless, the absolute frequency of hospital admissions related to PNB was low and should not dissuade healthy men who would benefit from early prostate cancer diagnosis from undergoing biopsy when clinically indicated.

DNA methylation markers could serve as useful biomarkers, both as markers for progression and for urine-based diagnostic assays. ⋯ We have identified four methylation markers that predict progression in pTa tumours, thereby allowing stratification of patients for personalised follow-up. In addition, we identified CGIs that will enable detection of bladder tumours in voided urine.

Review
Systematic review of oncological outcomes following surgical management of localised renal cancer.
Renal cell carcinoma (RCC) accounts for 2-3% of adult malignancies. There remain uncertainties over the oncological outcomes for the surgical management of localised RCC. ⋯ The evidence base suggests localised RCCs are best managed by nephron-sparing surgery where technically feasible. However, the current evidence base has significant limitations due to studies of low methodological quality marked by high risks of bias.
