INTRODUCTION: Intravesical instillations for adjuvant treatment of non-muscle-invasive bladder cancer (NMIBC) may be postponed of necessity. However, the frequency and reasons for postponement are unclear.
MATERIALS: We carried out a prospective, epidemiological study in an Urology department of the Île-de-France, between August 2016 and March 2017, to determine the frequency and reasons for postponement of intravesical instillations during adjuvant treatment of NMIBC. One-hundred consecutive patients treated by intravesical instillations of mitomycin C (MMC) or Bacillus Calmette-Guérin (BCG) were included. At each session and in case of instillation postponement, the medical team completed a specially designed questionnaire.
RESULTS: A total of 541 instillations were performed in the 100 patients. Twenty-four instillations (4.4%) were postponed in 19 patients. The major cause of postponement was an untreated positive urine analysis and culture (UAC) in 13/24 (54%) cases. The causes of cancellation did not differ significantly between MMC and BCG. The most frequently cancelled instillations were the first in the therapeutic protocol in 26% of cases. The number of instillations preceding those cancelled did not differ significantly between MMC and BCG (2.1±2.0 instillations for MMC vs. 1.5±1.6 for BCG; P=0.64).
CONCLUSIONS: There was a low rate of postponed instillations (4.4%). The main reasons, namely an untreated UAC and a positive dipstick test, based on the jurisprudence, are not included in the latest CC-AFU guidelines.
LEVEL OF EVIDENCE: 3.
