Medulloblastoma in children 0-3 years old: forty years' experience in slovenia.

Twenty-one children 0-3 years with MB were admitted 1960-1996, of 14 before treated 1984, 3 had no treatment, 5 had postoperative RT, one had radioactive gold IT. Seven treated 1986-1996 had preradiation Cht, 5 with HDCy. Of the 14 treated before 1984, 12 died within 1 year, one after 42 years in hypopharynx cancer, one is alive, of normal height and working. Of the 7 treated 1986-1996, 3 with disseminated disease died. Four are longtime survivors, 2 treated with reduced doses of RT of normal development. Preradiation Cht with HDCy and reduced doses of RT seems to be a reasonable approach.
