Abstract

According to these data, early treatment failure after 6 weekly instillations of 120 mg Immun BCG Pasteur F is an alarming signal which requires immediate re-assessment of the patient to exclude a muscle-invasive bladder cancer or an extravesical carcinoma in situ, either in the upper urinary tract or in the prostatic urethra.
