To determine the frequency and predictors of non-muscle invasive bladder tumour recurrence on first-check cystoscopy after transurethral resection of bladder tumour.
This cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, from April to November 2014, and comprised patients with a suspected newly-diagnosed urothelial cancer. Patients with non-muscle invasive disease with complete resection of all visible lesions along with deep biopsy from the tumour base were included. Patients received standard adjuvant intravesical therapy according to their risk stratification and underwent a white-light check cystoscopy at 3 months to look for tumour recurrence. Association between clinico-pathological variables and recurrence at first cystoscopy was determined. SPSS 20 was used for data analysis.
The mean age of 84 patients at presentation was 63.3±12.5 years (range: 36-89 years). There were 75(89%) men and 9(11%) women. On initial transurethral resection, the size of tumour was less than 3cm in 32(38%) participants and equal to or above 3cm in 52(62%). Single tumour was found in 51(61%) subjects and multiple tumours in 33(39%). None of the resected tumours was primary carcinoma in situ and 35(42%) tumours were of high grade. The overall recurrence rate at first cystoscopy was 28(33.3%). Larger tumour, higher grade and tumour multifocality were factors associated with recurrence at check cystoscopy (p<0.05 each). Patients\' age, gender, smoking status and tumour stage did not correlate with early recurrence (p>0.05 each).
The number, size and grade of the tumour strongly correlated with recurrence at check cystoscopy.
