AbstractThere is evidence that a history of benign prostatic hyperplasia increases the incidence of bladder cancer, and treatment with 5-alpha reductase inhibitor or androgen deprivation therapy reduces recurrence of non-muscle invasive bladder cancer. We aimed to evaluate whether prostate volume affects its prognosis. We reviewed medical records of men who underwent transurethral resection of bladder tumor due to non-muscle invasive bladder cancer from January 2012 to December 2017. Patients were divided into two groups based on prostate volume measured by computed tomography (group 1: 264 patients with ≤ 30 mL, group 2: 124 patients with > 30 mL). Propensity score matching analysis was used for adjust selection bias, and then assessed recurrence-free survival and progression-free survival. With a median follow up duration of 52 months, group 1 showed higher 5-year recurrence-free and progression-free survival (69.3% vs 47.0%, p = 0.001; 96.7% vs 87.7%, p = 0.002). Further, cox-regression analysis showed that tumor size (HR = 1.292 p < 0.001), multifocal tumor (HR = 1.993, p < 0.001), adjuvant intravesical therapy (chemotherapy: HR = 0.580, p = 0.037 and bacillus Calmette–Guérin: HR = 0.542, p = 0.004) and prostate volume (HR = 2.326, p < 0.001) were significant predictors of recurrence-free survival. Prostate volume (HR = 2.886, p = 0.014) was also associated with PFS with age (HR = 1.043, p = 0.044) and tumor grade (HR = 3.822, p = 0.013). We conclude higher prostate volume is associated with worse recurrence and progression-free survival in non-muscle invasive bladder cancer.

294 Background: Combination chemotherapy is the standard of care for neoadjuvant, adjuvant, and metastatic bladder cancer due to increased efficacy when compared to monotherapy. We report our experience with sequential intravesical combination chemotherapy using gemcitabine and mitomycin C (MMC) for non-muscle invasive bladder cancer (NMIBC). Methods: We performed a multi-institutional retrospective review of 47 consecutive patients who received 6 weekly treatments with sequential gemcitabine (1g) and mitomycin C (40mg) chemotherapy for NMIBC. Thirty patients received treatment at University of Iowa, 14 at UCSF and 3 at University of Minnesota. Results: A total 47 patients (median age 70, range 32-85; 36 males, 11 females) previously failing a median of 2 intravesical treatments were reviewed. The complete response (CR), 1-year recurrence-free survival (1-RFS) and 2-year recurrence-free survival (2-RFS) for all patients was 68%, 48% and 38%, respectively. In all, 14 of 47 patients (30%) remain free of recurrence with a median time to followup of 26 months (range 6-80 months). The median time to recurrence for all patients who recurred was 4 months (range 1-33 months). Ten patients required cystectomy. Conclusions: Sequential intravesical combination chemotherapy using gemcitabine and MMC appears to be a useful treatment for patients with a history of NMIC which has failed BCG or other intravesical therapy, in addition to patients with intermediate and high-risk disease.

Background and Purpose: The European Association of Urology guidelines recommend restaging transurethral resection of bladder tumours (reTURB) 2–6 weeks after primary TURB. However, in clinical practice some patients undergo a second TURB procedure after Bacillus Calmette-Guérin immunotherapy (BCG)induction. To date, there are no studies comparing post-BCG reTURB with the classic pre-BCG approach. The aim of this study was to assess whether the performance of reTURB after BCG induction in T1HG bladder cancer is related to potential oncological benefits. Materials and Methods: Data from 645 patients with primary T1HG bladder cancer treated between 2001 and 2019 in 12 tertiary care centres were retrospectively reviewed. The study included patients who underwent reTURB before BCG induction (Pre-BCG group: 397 patients; 61.6%) and those who had reTURB performed after BCG induction (Post-BCG group: 248 patients, 38.4%). The decision to perform reTURB before or after BCG induction was according to the surgeon’s discretion, as well as a consideration of local proceedings and protocols. Due to variation in patients’ characteristics, both propensity-score-matched analysis (PSM) and inverse-probability weighting (IPW) were implemented. Results: The five-year recurrence-free survival (RFS) was 64.7% and 69.1% for the Pre- and Post-BCG groups, respectively, and progression-free survival (PFS) was 82.7% and 83.3% for the Pre- and Post-BCG groups, respectively (both: p > 0.05). Similarly, neither RFS nor PFS differed significantly for a five-year period or in the whole time of observation after the PSM and IPW matching methods were used. Conclusions: Our results suggest that there might be no difference in recurrence-free survival and progression-free survival rates, regardless of whether patients have reTURB performed before or after BCG induction.

296 Background: Valrubicin was approved in the United States in 1998, removed from the market in 2002 because of manufacturing issues, and reintroduced in 2009. We report secondary outcomes and concomitant medication use from a US multicenter, observational, retrospective study. Methods: Medical records of adult patients with non–muscle-invasive bladder cancer (NMIBC) who used valrubicin were abstracted (March–September 2011). Kaplan-Meier analyses were performed for disease-free survival (DFS), progression-free survival (PFS), worsening-free survival (WFS), cystectomy-free survival (CFS), and time to cystectomy. Results: 113 patients (mean age, 73.7 years) received intravesical valrubicin (median, 6 instillations [range, 2–18]). 107 patients (94.7%) received >3 instillations; 97 (85.8%) completed the full course of therapy (≥6 instillations). DFS was 51.6% (95% CI, 40.9%–61.3%) at 3 months, 30.4% (95% CI, 20.4%–41.1%) at 6 months, and median DFS was 3.5 months (95% CI, 2.5–4.0). PFS was 97.6% (95% CI, 90.9%–99.4%) at 3 months, 87.2% (95% CI, 75.4%–93.5%) at 6 months, and median PFS was 18.2 months (95% CI, 17.2–19.0). WFS was 47.4% (95% CI, 37.2%–57.0%) at 3 months and 28.1% (95% CI, 18.8%–38.2%) at 6 months. CFS was 98.0% (95% CI, 92.2%–99.5%) at 3 months and 93.7% (95% CI, 85.2%–97.4%) at 6 months. Median CFS was not reached; only 13.3% of patients underwent radical cystectomy after starting valrubicin. 56 patients (49.6%) experienced ≥1 local adverse reaction; the most common were hematuria and pollakiuria (both 17.7%), micturition urgency (15.9%), and bladder spasm (14.2%). 55 patients (48.7%) used ≥1 concomitant medication for local adverse reactions; the most commonly used were urinary antispasmodics (21.2%), fluoroquinolones (14.2%), and other urologicals (14.2%). Conclusions: In patients with NMIBC treated with intravesical valrubicin, median DFS and PFS were 3.5 and 18.2 months, respectively, and median CFS was not reached as only 13% of patients underwent radical cystectomy. Valrubicin was well tolerated, and most patients received the full course of 6 instillations. Funding: Research and abstract were supported by Endo Pharmaceuticals Inc.
