Abstract

Non‐muscle‐invasive bladder cancer (NMIBC) is the most common form of bladder cancer, with frequent recurrences and risk of progression. Risk‐stratified treatment and surveillance protocols are often used to guide management. In 2017, BJUI reviewed guidelines on NMIBC from four major organizations: the American Urological Association/Society of Urological Oncology, the European Association of Urology, the National Comprehensive Cancer Network, and the National Institute for Health and Care Excellence. The present update will review major changes in the guidelines and broadly summarize new recommendations for treatment of NMIBC in an era of bacillus Calmette‐Guérin shortage and immense novel therapy development.

Abstract

Objective

To investigate whether the timing of an immediate instillation of mitomycin C (on the day of transurethral resection of bladder tumour [TURBT] or 1 day later) has an impact on time to recurrence of non‐muscle‐invasive bladder cancer (NMIBC).

Patients and Methods

All patients with NMIBC who were enrolled in a prospective trial between 1998 and 2003, and treated with an early mitomycin C instillation (on the day of TURBT or 1 day later), were selected. Statistical analysis was performed with Kaplan–Meier curves and multivariable Cox regression.

Fig. 1 Kaplan–Meier analysis showing time to recurrence for patients treated with an immediate instillation of MMC on the day of TURBT (Day‐0 group) or 1 day after (Day‐1 group).

Results

Administering an instillation of mitomycin C on the day of TURBT or 1 day later did not show a statistically significant difference in time to recurrence in a univariable model (log‐rank P = 0.99). After correcting for the number of scheduled adjuvant instillations, no statistically significant difference could be detected either: hazard ratio 1.05 (95% confidence interval 0.81–1.35, P = 0.74).

Conclusion

These data do not support the hypothesis that a very early instillation (on the day of TURBT) of mitomycin C decreases the risk of recurrence as compared with an early instillation (1 day after TURBT).

Guideline of guidelines: non-muscle-invasive bladder cancer

/by

Abstract

Non-muscle-invasive bladder cancer (NMIBC) represents the vast majority of bladder cancer diagnoses, but this definition represents a spectrum of disease with a variable clinical course, notable for significant risk of recurrence and potential for progression. Management involves risk-adapted strategies of cystoscopic surveillance and intravesical therapy with the goal of bladder preservation when safe to do so. Multiple organizational guidelines exist to help practitioners manage this complicated disease process, but adherence to management principles among practising urologists is reportedly low. We review four major organizational guidelines on NMIBC: the American Urological Association (AUA)/Society of Urologic Oncology (SUO), European Association of Urology (EAU), National Comprehensive Cancer Network (NCCN), and National Institute for Health and Care Excellence (NICE) guidelines.

Controversies in management of high-risk prostate and bladder cancer

/by
CaptureRecently, there has been substantial progress in our understanding of many key issues in urological oncology, which is the focus of this month’s BJUI. One of the most substantial paradigm shifts over the past few years has been the increasing use of radical prostatectomy (RP) for high-risk prostate cancer and increasing use of active surveillance for low-risk disease [1,2]. 
Consistent with these trends, this month’s BJUI features several useful articles on the management of high-risk prostate cancer. The first article by Abdollah et al. [3] reports on a large series of 810 men with D’Amico high-risk prostate cancer (PSA level >20 ng/mL, Gleason score 8–10, and/or clinical stage ≥T2c) undergoing robot-assisted RP (RARP). Despite high-risk characteristics preoperatively, 55% had specimen-confined disease at RARP, which was associated with higher 8-year biochemical recurrence-free (72.7% vs 31.7%, P < 0.001) and prostate cancer-specific survival rates (100% vs 86.9%, P < 0.001). The authors therefore designed a nomogram to predict specimen-confined disease at RARP for D’Amico high-risk prostate cancer. Using PSA level, clinical stage, maximum tumour percentage quartile, primary and secondary biopsy Gleason score, the nomogram had 76% predictive accuracy. Once externally validated, this could provide a useful tool for pre-treatment assessment of men with high-risk prostate cancer. 
Another major controversy in prostate cancer management is the optimal timing of postoperative radiation therapy (RT) for patients with high-risk features at RP. In this month’s BJUI, Hsu et al. [4] compare the results of adjuvant (≤6 months after RP with an undetectable PSA level), early salvage (administered while PSA levels at ≤1 ng/mL) and late salvage RT (administered at PSA levels of >1 ng/mL) in 305 men with adverse RP pathology from the USA Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) registry. At 6.2 years median follow-up, late salvage RT was associated with significantly higher rates of metastasis and/or prostate cancer-death. By contrast, there was no difference in prostate cancer mortality and/or metastasis between early salvage vs adjuvant RT. A recent study from the USA National Cancer Data Base reported infrequent and declining use of postoperative RT within 6 months for men with adverse RP pathology, from 9.1% in 2005 to 7.3% in 2011 [5]. As we await data from prospective studies comparing adjuvant vs early salvage RT, the results of Hsu et al. [4] are encouraging, suggesting similar disease-specific outcomes if salvage therapy is administered at PSA levels of <1 ng/mL. 
Finally, this issue’s ‘Article of the Month’ by Baltaci et al. [6] examines the timing of second transurethral resection of the bladder (re-TURB) for  high-risk non-muscle-invasive bladder cancer (NMIBC). The management ofbladder cancer at this stage is a key point to improve the overall survival of bladder cancer. Re-TURB is already recommended in the European Association of Urology guidelines [7], but it remains controversial as to whether all patients require re-TURB and what timing is optimal. The range of 2–6 weeks after primary TURB was established based on a randomised trial assessing the effect of re-TURB on recurrence in patients treated with intravesical chemotherapy [8], but it has not been subsequently tested in a randomised trial. Baltaci et al. [6], in a multi-institutional retrospective review of 242 patients, report that patients with high-risk NMIBC undergoing early re-TURB (14–42 days) have better recurrence-free survival vs later re-TURB (73.6% vs 46.2%, P < 0.01). Although prospective studies are warranted to confirm their results, these novel data suggest that early re-TURB is significantly associated with lower rates of recurrence and progression.
