TABLE 1.

BCMA expression by IHC on different B-cell malignancies. Per tumor type, the amount of tumor cells was determined. BCMA positivity either on membrane or in golgi was determined as percentage of total tumor cells. Percentages were assessed independently by two pathologists.

Disease	N	%Tumor cells	%BCMA+ of tumor cells	BCMA membrane intensity	BCMA golgi intensity
MM	4	70–98	60–90	Absent to strong	Weak to strong
LPL (WM)	3	20–65	10–90	Weak to moderate	Weak to moderate
DLBCL	3	7–90	0–8	Absent to moderate	Absent to moderate
CLL	4	90–95	0–0.5	Absent to weak	Absent to weak
MCL	3	80–90	0	Absent	Absent
