Background: Trans-urethral resection of bladder tumor is an essential diagnostic tool as well as effective treatment modality for non-muscle invasive bladder cancer. We aimed to evaluate the recurrence and progression of the non-muscle invasive bladder cancer in Nepalese patients. Methods: This was a retrospective study of 43 patients with non-muscle invasive bladder cancer, who underwent trans-urethral resection of bladder tumour followed by adjuvant intravesical instilla­tion of chemo or immunotherapy between January, 2013 to December, 2018. Patients were divided into low, intermediate and high-risk groups according to the clinical and pathological factors used by the European Organization for Research and Treatment of Cancer scoring system. Outcomes were calculated in terms of recurrence and progression in each group. Results: Out of 43 patients, 11 (25.58%) patients had low risk, 18 (41.86%) patients had intermediate risk and 14 (32.56%) patients had high risk of recurrence categories. No recurrence and progression of the disease noted in low risk group. In the intermediate risk group, out of 18 patients, 4 (22.2%) patients developed recurrence and 2 (11.1%) patients had progression of disease. In high risk group, out of 14 patients, 4 (26.8%) patients developed recurrence and 2 (14%) patients developed progres­sion of the disease. Conclusions: Even in a low volume centre of bladder cancer, effective treatment for non-muscle inva­sive bladder cancer with trans-urethral resection of bladder tumour followed by adjuvant intravesical chemo or immunotherapy can be given safely to reduce recurrence and progression of the disease.

Background: Many regimes of intravesical therapy have been tried in attempt to reduce the recurrence rate of non muscle invasive bladder cancer, these generally require frequent attendance for instillation. Multiple non-comparative studies have demonstrated the favourable outcomes of the immediate treatment by instillation of mitomycin C after transurethral resection of bladder tumor (TURBT) in cases of non-muscle invasive Transitional Cell Carcinoma.Objective: To compare frequency of tumour recurrence in low risk transitional cell carcinoma of bladder between single dose Mitomycin C instillation and control group.Material and Methods: This study was conducted at urology departmentsaidu teaching hospital and Nawaz sharif kidney center swat. Study Design Quasi Experimental.Study Duration was (From: Feb 2018 to February 2019). Total 62 patients fulfilling the inclusion criteria were selected. Patient were divided between group A and B according to Non probability purposive sampling. TURBT was done in all patients. In those assigned to group A Mitomycin C 40mg was instilled through foleys catheter and clamped within 12 hrs of resection once haematuria has cleared. Mitomycin C was retained for 2 hrs and then foleys catheter was removed.Results: Mean age of patients in Group-A and in Group-B was 54.90±11.48 and 60.03±13.58 years respectively. In Group-A 1(3.2%) and in Group-B 9(29%) patients had recurrence after 3 months follow up time period. Recurrence rate of Group-B was significantly higher. i.e. (p-value=0.006).Conclusion: Results of this study showed the superiority of mitomycin C in patients with low risk non muscle invasive bladder cancer in terms of significantly lower recurrence rate as compared to that of control group. So, it can be said that single mitomycin C instillation significantly decrease recurrence in patients with low risk non muscle invasive bladder cancer.
