[Recurrence prevention of papillomas of the bladder using lycurim instillation].

Following surgical removal of papillary tumours of the bladder from 60 patients the authors performed short instillations of the bladder with LYCURIM. The histological picture revealed tumours in the stage O-A-B1 and grade I-II-III. In a control group (n = 129) 89 recidive cases were observed in 2 years. Out of the 60 patients of the LYCURIM group 19 (31.7%) were free of tumours for 2 years and 43 (71.7%) for 11/2 years. A transient cystitis which occurred with short application of the medicament was easily cured. Toxic effects on the blood picture were not observed.
