Stem Cell CollectionStem Cell Collection

• After 4 cycles of RVD she achieves a VGPR with kappa light chains reduced to 10 and lambda light chains recovered to 0.1.

• Her marrow reveals 4% kappa restricted plasma cells.

• MRI demonstrates significant resolution of infiltrative images.

• She agrees to proceed to stem-cell collection and transplantation.

What we don’t knowWhat we don’t know

• Is VRD superior to VTD or CyBorD?• Should the goal be ‘X” number of cycles and

proceed to SCT or should patients continue induction until best response?

• Is “response adapted” therapy appropriate?• Is there a role for carfilzomib based induction?• Should anybody be chemomobilized in the era of

plerixafor?

Stem Cell TransplantationStem Cell Transplantation

• She collects 10 million CD34 cells per kg over 3 days and is ready to be admitted for high dose melphalan and autologous stem cell transplantation.

• She asks what is it going to be like and does she really need a SCT?

• Should everybody be collected upfront?– How much?

• Who should undergo upfront SCT?– All patients?– Only those with suboptimal response?

What is suboptimal?– PR– VGPR– Near CR

– Who is truly transplant ineligible?– What about low risk patients in CR?

• What role does risk stratification play in deciding therapies?

In my humble opinionIn my humble opinion

• High dose melphalan is one of the most active agents in myeloma today– 30-40% CR– 24 months median remission duration without maintenance– Name another agent with similar single agent activity– It is also cost-effective

• With stem cell support it can be given safely to older patients with comorbidities.

• Thus not planning for it’s use upfront is similar to telling a patient I am never going to use bortezomib or lenalidomide during your disease course because “I don’t like it” or I don’t believe in it”.

• Whether early or late, once twice or more times it remains an active agent that can be extremely effective in all stages of the patients disease journey.

Tales of Two Cases

Case 1• 55-year-old female presents

with asymptomatic anemia of 10 gm/dL and total serum protein 10 gm/L

• Workup reveals– 30% plasma cells– Cytogenetic diploid– IgA kappa peak of 3.2– β2M of 3.0

• Receives 4 cycles of Bz/Thal/Dex

• Followed by Auto SCT on day 60 documented stringent CR

Case 2• 55-year-old female presents

with asymptomatic anemia of 10 gm/dL and total serum protein 10 gm/L

• Workup reveals– 30% plasma cells– Cytogenetic t(4;14)– IgA kappa peak of 3.2– β2M of 3.0

• Receives 4 cycles of Bz/Thal/Dex

• Followed by Auto SCT on day 60 documented paraprotein peak of 0.4 g/dL

Both have a 10/10 sibling donor available.

Summary

• High dose melphalan with autologous stem cell support remains the standard of care for consolidation therapy for patients with chemosensitive disease

• Current therapy with high dose melphalan followed by maintenance therapy results in more than 70% major responses and median remission durations of around 3.5-4 years.

• Moving forward minimizing toxicities, developing more effective conditioning regimens and better risk stratification will allow us to provide each patient with the best chance of a long life with myeloma control, good quality of life with the least treatment burden
