The use of immediate postoperative instillations of intravesical chemotherapy after TURBT of NMIBC among European countries

Purpose The aim of this study was to assess the use of immediate postoperative instillation of intravesical chemotherapy (IPOIC) after transurethral resection of bladder tumour (TURBT) of nonmuscle invasive bladder cancer (NMIBC) in Europe. Methods Urologists based in five European Union nations were asked to extract information from the records of patients with NMIBC–urothelial carcinoma who received at least one TURBT. Multivariate logistic regression models were developed to determine the significant predictors of IPOIC usage. Data were weighted to control for country-to-country and other differences. Results Overall, 324 urologists (58 France, 72 Germany, 62 Italy, 65 Spain, 67 United Kingdom) were involved; the participation rate was 55 %. Overall, 771 patients received 954 TURBTs (mean—1.2/patient), of which 413 of the TURBTs (43.3 %) were administered IPOIC . Sixty-six of the 413 IPOICs (16.0 %) were for a recurrent tumour. Five of the tested variables were significantly associated with a patient’s likelihood of receiving IPOIC after TURBT. Variables in the order of significance are as follows: (1) country (United Kingdom, patients most likely to receive IPOIC; France, least likely); (2) progression risk (physician assessed) [lower-risk conditions (no CIS, tumour
