Clinical stage and number of cases	Initial treatment approach	Study findings	Survival	Reference
Stage I/II, n = 6 Stage III/IV, n = 6	CHOP for stage I/II (n = 6) APO w/wo IDMTX and HiDAC for stage III/IV (n = 6)	No relapses in patients with limited stage disease Relapse occurred in 4/6 with advanced stage	5-y EFS: 60%∗ 5-y OS: 70%∗	6
Stage I/II, n = 7 Stage III/IV, n = 10	T-LLy/ALL regimen (n = 12) B-NHL regimen (n = 5)	5/7 with stage I/II survived 5/10 with stage III/IV disease survived	Follow-up: 59% were alive	7
Stage I/II, n = 3 Stage III/IV, n = 15	LLy regimen (n = 5) ALCL-like regimen (n = 12) B-NHL regimen (n = 1)	16 achieved CR 5 relapsed after reaching CR; 1 survived after relapse	5-y EFS and OS: 61% ± 11% and 65% ± 11%	9
