BACKGROUND: The European Association of Urology (EAU) prognostic factor risk groups for non-muscle-invasive bladder cancer (NMIBC) are used to provide recommendations for patient treatment after transurethral resection of bladder tumor (TURBT). They do not, however, take into account the widely used World Health Organization (WHO) 2004/2016 grading classification and are based on patients treated in the 1980s. OBJECTIVE: To update EAU prognostic factor risk groups using the WHO 1973 and 2004/2016 grading classifications and identify patients with the lowest and highest probabilities of progression. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for primary NMIBC patients were collected from the institutions of the members of the EAU NMIBC guidelines panel. INTERVENTION: Patients underwent TURBT followed by intravesical instillations at the physician's discretion. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable Cox proportional-hazards regression models were fitted to the primary endpoint, the time to progression to muscle-invasive disease or distant metastases. Patients were divided into four risk groups: low-, intermediate-, high-, and a new, very high-risk group. The probabilities of progression were estimated using Kaplan-Meier curves. RESULTS AND LIMITATIONS: A total of 3401 patients treated with TURBT ± intravesical chemotherapy were included. From the multivariable analyses, tumor stage, WHO 1973/2004-2016 grade, concomitant carcinoma in situ, number of tumors, tumor size, and age were used to form four risk groups for which the probability of progression at 5 yr varied from <1% to >40%. Limitations include the retrospective collection of data and the lack of central pathology review. CONCLUSIONS: This study provides updated EAU prognostic factor risk groups that can be used to inform patient treatment and follow-up. Incorporating the WHO 2004/2016 and 1973 grading classifications, a new, very high-risk group has been identified for which urologists should be prompt to assess and adapt their therapeutic strategy when necessary. PATIENT SUMMARY: The newly updated European Association of Urology prognostic factor risk groups for non-muscle-invasive bladder cancer provide an improved basis for recommending a patient's treatment and follow-up schedule.

CONTEXT: Most series have suggested better perioperative outcomes of laparoscopic radical nephroureterectomy (RNU) over open RNU. However, the oncological safety of laparoscopic RNU remains controversial. OBJECTIVE: To systematically review all relevant literature comparing oncological outcomes of open versus laparoscopic RNU. EVIDENCE ACQUISITION: A systematic literature search using the Medline, Embase, and Cochrane databases and clinicaltrial.gov was performed in December 2014 and updated in August 2016. Randomised controlled trials (RCTs) and prospective or retrospective nonrandomised comparative studies comparing the oncological outcomes of any laparoscopic RNU with those of open RNU were included. The primary outcome was cancer-specific survival. The risk of bias (RoB) was assessed using Cochrane RoB tools. A narrative synthesis of the evidence is presented. EVIDENCE SYNTHESIS: Overall, 42 studies were included, which accounted for 7554 patients: 4925 in the open groups and 2629 in the laparoscopic groups. Most included studies were retrospective comparative series. Only one RCT was found. RoB and confounding were high in most studies. No study compared the oncological outcomes of robotic RNU with those of open RNU. Bladder cuff excision in laparoscopic groups was performed via an open approach in most studies, with only three studies reporting laparoscopic removal of the bladder cuff. Port-site metastasis rates ranged from 0% to 2.8%. No significant difference in oncological outcomes was reported in most series. However, three studies, including the only RCT, reported significantly poorer oncological outcomes in patients who underwent laparoscopic RNU, especially in the subgroups of patients with locally advanced (pT3/pT4) or high-grade upper tract urothelial carcinoma (UTUC), as well as in instances when the bladder cuff was excised laparoscopically. CONCLUSIONS: The current available evidence suggests that the oncological outcomes of laparoscopic RNU may be poorer than those of open RNU when bladder cuff is excised laparoscopically and in patients with locally advanced high-risk (pT3/pT4 and/or high-grade) UTUC. PATIENT SUMMARY: We reviewed the literature comparing the outcomes of two different surgical procedures for the treatment of upper tract urothelial carcinoma. Open radical nephroureterectomy is a surgical procedure in which the kidney is removed through a large incision in the abdomen, while in laparoscopic radical nephroureterectomy, the kidney is removed through a number of small incisions. Our findings suggest that the outcomes of laparoscopic radical nephroureterectomy may be poorer than those of open radical nephroureterectomy, particularly when the bladder cuff is also required to be removed. Laparoscopic radical nephroureterectomy may also be less effective in patients with locally advanced (pT3/pT4) or high-grade upper tract urothelial carcinomas.
