Local mitomycin-C therapy in relapse-prevention of superficial bladder neoplasms treated by means of laser.

Authors report on local mitomycin-C (MTM-C) therapy applied subsequent to the treatment by means of Nd-YAG laser in 59 superficial (Ta-T1) bladder neoplasms. Relapse-rate in the neoplasms could be reduced by using MTM-C accompanied by minor side-effects. Seventy-two % of patients have been free from relapse for the mean 44-month follow-up period. Authors also suggest that laser therapy may favourably be completed by local chemoprophylaxis in "high-risk" type superficial bladder neoplasms.
