Abstract Introduction and Aims Almost three quarters of patients diagnosed with bladder cancer have non-muscle invasive disease. The European Association of Urology (EAU) guidelines recommend the use of intravesical instillation of Mitomycin C (MMC) to reduce the rate of recurrence. Methods A retrospective cohort analysis was carried out of all patients who underwent a TURBT between January 2016 and January 2019 in our Trust. A comparison of recurrence outcomes was investigated between patients who had immediate instillation of MMC (within 1 hours post-TURBT) versus early instillation (within 24 hours post-TURBT). Recurrence was assessed at 3 months cystoscopy and at 1 year follow-up. Results 201 patients were included. 100 underwent immediate MMC instillation (75% male, 25% female); 101 early instillation (72% male, 28% female). There was 11% recurrence (immediate) versus 13% (early) in instillation groups at 3 months. At first year, recurrence was seen in 12% (immediate) versus 14% (early) groups. Of these recurrences, there was an upstaging of tumour in 27% (immediate) versus 31% (early) at the 3 monthly follow-up and 25% (immediate) versus 28% (early) at the 1st year. The mean period of post-operative stay following initial TURBT was 0.8 days in the immediate versus 1.1 days in the early instillation groups. Conclusion Although no statistical differences were seen in this study, the results appear to favour immediate instillation of MMC after TURBT with respect to reduction in recurrence and upstaging rates. Post-operative length of stay in hospital was also shorter in patients who had an immediate MMC instillation.

Background: Approximately 70% of urinary bladder cancer are non-muscle invasive at presentation. It is notorious for its high incidence and recurrence rate. The five-year recurrence rate varies between 30 and 60%. The intravesical treatment evolved out of need to prevent tumour recurrence after local surgical resection.Objectives: To compare intravesical Mitomycin C and BCG therapies in the prevention of recurrences and severity of their side effects.Materials and Methods: 40 patients with superficial bladder cancer were studied in urology unit of surgery department of North Bengal Medical College, Darjeeling from June, 2012 to May, 2013. They underwent transurethral resection of bladder tumour. Post operatively 19 patients were treated by intravesical Mitomycin C and 21 patients with BCG. Post intravesical therapy, patients were monitored 3 monthly for recurrence and side effects.Results: No recurrence was observed at the 3rd month follow up, two recurrences were observed at the end of 6th month in the Mitomycin C group. Regarding side effects, cystitis had no significant difference between the two groups but fever, hematuria and retention of urine were found significantly in BCG group during the study period.Conclusions: In the prevention of recurrences, intravesical Mitomycin C and BCG therapies have comparable efficacies at the end of 6 months. A further follow up period is required to see and compare the long term results. The incidence of the side effects although mild was much higher with intravesical BCG therapy.Bangladesh Journal of Medical Science Vol.15(1) 2016 p.74-77

Purpose: To assess the efficacy of intra-arterial chemotherapy as a bladder-preservation treatment in patients with muscle-invasive bladder cancer (MIBC) following transurethral resection of bladder tumors (TURBT). Materials and Methods: From 2005 June to 2012 November, 46 patients diagnosed with MIBC (clinical stage T2-T3N0M0) underwent three courses of cisplatin-based intra-arterial chemotherapy as a remedial approach for bladder preservation after TURBT. All patients also received intravesical instillation of chemotherapy as a maintenance strategy. Results: All 46 patients completed the treatment with minor complications. The median follow-up time was 34.5 months (range, 8-87 months). Thirty-two patients (69.6%) demonstrated complete response. The three-year and five-year overall survival was 70.65 and 61.23%, and the disease-specific survival over the same periods was 78.03 and 67.62%, respectively. During the entire follow-up period, more than 80% preserved their bladder. Conclusions: Intra-arterial chemotherapy can be performed as a remedial treatment for MIBC patient following TURBT. Combined with TURBT, it offers an option for bladder preservation therapy on patients who are unable or unwilling to undergo radical cystectomy.

Abstract Aim Non-muscle-invasive bladder cancer (NMIBC) is the most prevalent form of bladder cancer, predominantly affecting the elderly population. The most common treatment for recurrent NMIBC is transurethral resection of the bladder tumour (TURBT), which carries a risk of perioperative morbidity and mortality in this often-co-morbid population. Outpatient laser ablation of low-grade NMIBC recurrences is a minimally invasive treatment option, but long-term efficacy is poorly reported. Method We retrospectively reviewed the case notes of all patients treated with Holmium:YAG laser ablation from 2008-2016. Data regarding patient demographics, original histology, dates of procedures, follow-up time, recurrence, progression, and complications were recorded. Results A total of 199 procedures were performed on 97 patients (mean age of 83.56), 73 (75.3%) of which originally had low-grade (G1 or G2) tumours. Overall, 55 (56.7%) patients developed tumour recurrence at long-term follow-up (mean 5.36 years), and only 9 (9.3%) patients had tumour progression to a higher stage or grade, but there was no progression to muscle-invasive disease. The median recurrence-free, progression-free and overall survival times were 1.69 years (95% CI 1.20-2.25), 5.70 years (95% CI 4.10-7.60) and 7.60 years (95% CI 4.90-8.70), respectively. No patients required emergency inpatient admission after laser ablation for any associated complications. Conclusions Office-based Holmium: YAG laser ablation is an oncologically-safe method of managing recurrent low-grade non-muscle-invasive bladder cancer in the long-term, with no patients progressing to muscle-invasive disease. Furthermore, the procedure is safe, and no significant complications were seen in this elderly and co-morbid population.

Abstract: Mitomycin C (MMC) is widely used in treatment of non-muscle invasive bladder cancer at a 1 mg/mL concentration, by intravesical instillation. MMC is also used as an ophthalmic procedure in glaucoma care mostly with 0.2 mg/mL concentration. To accelerate syringes provision, it could be interesting to demonstrate the stability of the drug, in order to be able to prepare the chemotherapeutic drug several hours before the chemotherapy administration.: A stability indicating HPLC-UV method was developed and validated according to the ICH guidelines. Concentrations of the MMC stored at 25 °C and 60 % of relative humidity and protected from light in polypropylene syringes (1 mg/mL and 0.2 mg/mL) or glass vials (1 mg/mL) were evaluated for 96 h and compared to the initial observed concentrations.: MMC stability was demonstrated in syringes and glass vials at 1 mg/mL only for 8 h in water for injections and for 10 h at 0.2 mg/mL in 0.9 % sodium chloride solutions, because relative concentrations (95 % confidence interval of the mean of 3 samples) were systematically over 90 % of the initial concentrations. After 96 h the relative concentrations were found below 80 % as compared to initial concentrations, thus indicating instability of these solutions. Degradation products were observed and remained below 3 %.: This study confirms that MMC solutions for ophthalmic application at 0.2 mg/mL or vesical instillation at 1 mg/mL have to be formulated extemporaneously to maintain the desired concentration.
