Benefit of ASCT
Not curative
improves OS by 12 months
Conditioning before ASCT
Melphalan
Timing of ASCT
Thaildomide pivotal study
CASSIOPEIA
Dara-VTD as 1st line
Thalidomide SE
Peripheral neuropathy
Somnolence
VTE
Constipation
Thalidomide benefits
Minimal myelosuppression
Minimal renal clearance- useful in AKI
VGPR
M protein detectable on immunofixation but not on electrophoresis
or
>90% reduction of M protein
and
M protein in urine < 100 mg/d
CR
Negative immunofixation in serum and urine
and
< 5% plasma cells in BM
and
No plasmacytomas
PR
> 50% reducition on M protein
and
BJ reduction of >50% or < 200 mg/d
or
if M protein not detectable- FLC reduction of >50%
and
> 50% reduction of the diameter of plasmacytomas
