Patient characteristics ().

Age	1–5 years = 26	6–11 years = 10	12–18 years = 6
Gender	Male = 21	Female = 21
Immunophenotype	B cell = 40	T cell = 2
Protocol of therapy	ALL IC BFM 2002: 1	ALL IC BFM 2009: 41
Risk group	SR: 5	IR: 25	HR: 12
CNS involvement	Positive: 2	Negative: 40
EFS	Relapse: 2	Death: 2 (after relapse: 0)	Live in first remission: 38
Steroid sensitivity	Good: 35	Poor: 6
BM on day 15	M1: 28	M2: 9	M3: 4
BM on day 33	M1: 38	M2: 1	M3: 2

One child died before the 8th day of the treatment, so we were not able to assess the sensitivity to steroids and the response to treatment on the 15th and 33rd days of chemotherapy.
