Background&Aim: High grade non-muscle invasive bladder cancer (NMIBC) is common in urological practice. Most of these cancers are or become refractory to intravesical immunotherapy and chemotherapy. Here we evaluated the efficacy of combined local bladder hyperthermia and intravesical mitomycin-C (MMC) instillation in patients with high-risk recurrent NMIBC. Materials and methods: Between February 2014 and December 2015, 18 patients with high risk NMIBC were enrolled. Patients were treated in an outpatient basis with 6 weekly induction sessions followed by monthly maintenance sessions with intravesical MMC in local hyperthermia with bladder wall thermo-chemotherapy (BWT) system (PelvixTT system, Elmedical Ltd., Hod Hasharon, Israel). The follow-up regimen included cystoscopy after the induction cycle and thereafter with regular intervals. Time to disease recurrence was defined as time from the first intravesical treatment to endoscopic or histological documentation of a new bladder tumour. Adverse events were recorded according to CTC 4.0 (Common Toxicity Criteria) score system. Results: Mean age was 72 (32-87) years. 10 patients had multifocal disease, 9 had CIS, 6 had recurrent disease and 2 had highly recurrent disease (> 3 recurrences in a 24 months period). 6 patients underwent previous intravesical chemotherapy with MMC. The average number of maintenance sessions per patient was 7.6. After a mean follow-up of 433 days, 15 patients (83.3%) were recurrence-free. 3 patients had tumour recurrence after a mean period of 248 days without progression. Side effects were limited to grade 1 in 2 patients and grade 2 in 1 patient. Conclusions: BWT seems to be feasible and safe in high grade NMIBC. More studies are needed to identify the subgroup of patients who may benefit more from this treatment.

4572 Background: In 2006, we reported that intravesical sequential bacillus Calmette-Guérin (BCG) and electromotive mitomycin in high risk non-muscle invasive bladder cancer leads to higher disease-free interval, lower recurrence and progression, and to improved overall survival and disease-specific survival compared with BCG alone. After an additional 6 years of follow-up, we now report estimated 16-year results. Methods: From 1994 through 2002, we randomly assigned 212 patients with high risk non.muscle invasive bladder cancer to 81 mg BCG infused over 120 min once a week for 6 weeks (n=105) or to 81 mg BCG infused over 120 min once a week for 2 weeks, followed by 40 mg electromotive mitomycin (intravesical electric current 20 mA for 30 min) once a week as one cycle for three cycles (n=107). Complete responders underwent maintenance treatment: those assigned BCG alone had one infusion of 81 mg BCG once a month for 10 months, and those assigned BCG and mitomycin had 40 mg electromotive mitomycin once a month for 2 months, followed by 81 mg BCG once a month as one cycle for three cycles. The primary endpoint was disease-free interval. Analyses were done by intention to treat. Results: Median follow-up was 121 months (IQR 70.5–163.5). Patients assigned sequential BCG and electromotive mitomycin had higher disease-free interval than did those assigned BCG alone (79 months [95% CI 27–139] vs 26 months [11–113]; difference between groups 53 months [39–67], log-rank p=0.0002). Patients assigned sequential BCG and electromotive mitomycin also had lower recurrence (45% [35–55] vs 62% [50–72], difference between groups 17% [6–28], log-rank p=0.0002); progression (12% [3–21] vs 28% [17.5–38.5], difference between groups 16% [5–27], log-rank p=0.003); overall mortality (44% [33–55] vs 59% [43–75], difference between groups 15% [2–28], log-rank p=0.01); and disease-specific mortality (9% [2.5– 15.5] vs 23% [11–34], difference between groups 14% [4–24], log-rank p=0.0055). Conclusions: In patients with high risk non-muscle invasive bladder cancer intravesical BCG combined with electromotive mitomycin provided better results than BCG alone in terms of higher remission rates and longer remission times.

356 Background: Currently, there are few well-validated data of the optimal schedule of follow-up after BCG intravesical instillation. The objective of the study were to elucidate the ability of conventional exams (cystoscopy, urine cytology) to diagnose presence of carcinoma and the significance of protocol biopsy after BCG intravesical treatment in patients with high-risk non-muscle-invasive bladder cancer (NMIBC). Methods: The study included patients treated with BCG intravesical treatment. From January 2002 to October 2012, we retrospectively reviewed a total of 72 patients (61 men and 11 women). The median age was 72 years (range 47-84). The pathological stages were Tis in 4 patients (6%), Ta in 29 (40%) and T1 in 39 (54%) (T1 with CIS in 30 [42%]). Tumors were multifocal in 56 (78%) and second TUR had been performed in 53 (74%) patients. We investigated the prognosis and accuracy of tumor existence by conventional exams referring with the protocol biopsy. A protocol biopsy was performed within 5 to 9 months after the final TUR. CTCAE v4.0 was used to grade adverse events. Results: Of 72 patients, we performed protocol biopsy in 62 patients and 9 (15%) had cancer. The conventional methods had a sensitivity of 78%, specificity of 81%, positive predictive value of 41% and negative predictive value of 96% in diagnosing cancer. Although three (5%) had grade2 adverse events, there were no grade 3 or greater adverse events. Of 53 patients with no cancer in protocol biopsy, 8 (8%) patients experienced a recurrence but 51patients (96%) were alive with no evidence of disease. Of 9 patients pointed out cancer in protocol biopsy, 7patients (78%) had no evidence of disease recurrence at last follow-up. The 5-year recurrence-free survival rate and overall survival rate were 77% and 95%, respectively. Conclusions: To the best of our knowledge, this is the first report of the ability of conventional exams for follow-up after BCG treatment. Our findings revealed that conventional exams were limited for meticulous follow-up, so that the protocol biopsy will be recommended to obtain the better survival in high-risk NMIBC patients.

e17031 Background: Management of high-risk non-muscle invasive bladder cancer (HR NMIBC) represents a clinical challenge due to high failure rates despite prior bacillus Calmette-Guérin (BCG) therapy. We describe real-world patient characteristics, long-term outcomes, as well as the economic burden in the HR NMIBC population. Methods: We identified a random sample of 412 HR NMIBC patients who received ≥ 1 dose of BCG within Veterans Affairs (VA) centers across the United States from January 1, 2000, to December 31, 2016. HR NMIBC was defined as high-grade Ta (TaHG), T1, and/or carcinoma-in-situ (CIS). We analyzed the number of BCG instillations received, as well as used the Kaplan-Meier method to estimate event-free survival for cystectomy and bladder cancer-specific death. All-cause expenditures were summarized as medians with corresponding interquartile ranges (IQR) and adjusted to 2019 USD. Results: The median (IQR) age at diagnosis was 67 years (61-74), with most patients being white (84%) and male (81%). At HR NMIBC diagnosis, 69 (17%) patients had CIS +/- T1 or TaHG, and 341 (83%) had TaHG or T1, no CIS. The vast majority of patients [n = 363, (90%)] received six BCG instillations (range: 1-7) within 365 days of the first dose. The total follow-up was 2,694 person-years. From BCG initiation to end of follow-up, the median all-cause expenditures per patient were $358,593 (257,699 – 652,853). Conclusions: In this equal access setting, the vast majority of HR NMIBC patients received 6 instillations of BCG within 1 year, although the interval over which the instillations were given varied among patients. Patients with CIS appeared to have a worse prognosis, as 24% underwent cystectomy, and 13% died of bladder cancer at 10 years of follow-up. These findings also highlight the considerable economic burden of HR NMIBC. [Table: see text]
