Table 2

Relationship between best response to initial bortezomib treatment and best response to bortezomib retreatment.

		Best response to bortezomib retreatment
		ORR (%)	CR	VGPR	PR	SD	PD
Best response to initial bortezomib treatment	ORR (%)	30	10 (33)	2 (7)	6 (20)	10 (33)	2 (7)
	CR	22 (73)	9	2	5	4	2
	VGPR	3 (10)	0	0	1	2	0
	PR	3 (10)	1	0	0	2	0
	SD	2 (7)	0	0	0	2	0

ORR: overall response rate; CR: complete response; VGPRL very good partial response; PR: partial response; SD: stable disease; PD: progressive disease.
