Variable	Cox Regression for RFS
	Risk (OR)	95%C.I. of OR	p
Ph/bcr-abl	4.53	1.42–14.4	0.01
Mediastinal mass	6.79	1.13–40.5	0.03
Male gender	1.43	0.47–4.35	NS
T-cell immunophenotype	1.68	0.39–7.26	NS
No. of induction to CR	1.34	0.29–6.10	NS
Variable	Cox Regression for OS
	Risk (OR)	95%C.I. of OR	p
Ph/bcr-abl	5.32	1.64–17.2	0.005
T-cell immunophenotype	3.04	1.09–8.52	0.03
Male gender	1.03	0.35–2.97	NS
LDH	2.51	0.92–6.84	NS
No. of induction to CR	0.61	0.10–3.54	NS

RFS, relapse-free survival; OR, odds ratio; NS, not significant; CR, complete remission; OS, overall survival.
