Smoldering Myeloma
Kyle NEJM 1980 (6 cases): We believe that a patient whose illness fulfills the criteria for the diagnosis of multiple myeloma should be observed off therapy if there is no anemia, bone lesions, hypercalcemia, or renal insufficiency . . . Therapy may lead to leukopenia . . . [And] unnecessary chemotherapy causes unnecessary expense, and it is a source of concern to the patient.

Asymptomatic Myeloma
Blood 1980;56:521
• Alexanian Blood 1980 (20 cases): Since asymptomatic patients with higher tumor mass grades . . . are even less common . . . chemotherapy should not be withheld in those rare asymptomatic patients with intermediate or high tumor mass. Also, the presence of an IgA myeloma protein or the excretion of more than 200 mg/day of Bence Jones protein favored the need for early chemotherapy. . . Serial assessments of myeloma protein level provided a useful index of changing tumor load and the need for chemotherapy.

Would you consider treatment for High Risk Smoldering multiple myeloma?
PostPosted: Thu Feb 28, 2013 4:23 pm
by DanaH
I would welcome the community's thoughts on early treatment of High Risk Smoldering multiple myeloma (high risk for progression to active disease) in the clinical trial setting. I am aware of early clinical trial intervention studies with [lenalidomide] w/ Dex (Spanish study group as well as some centers in the US, I believe Dr. Lonial @ Emory ) and carfilzomib, [lenalidomide] w/ Dex (NIH w/ Dr. Landgren). Have any smolderers considered this and actually participate(d) in these trials? Or would anyone currently under treatment for active multiple myeloma have or had considered this option prior to commencing treatment once their multiple myeloma became active, had you known you were at high risk for progression ? All opinions will be very much appreciated.

Dana H,I am in the NIH trial. I went to the NIH and had all the testing done planning to enter the natural history study. My testing showed that i was a high risk smolderer according to the both the italian and spanish study protocol. Dr Landgren felt that I had a 75% chance of converting to active myeloma in the next two years. They had introduced the CRD for smolderers at a previous visit so I was already considering it and those odds were not for me. I didn't want to wait to be symptomatic before starting to fight it.
They are having great results thus far! You need to meet them and have an evaluation before you think too much about this. Nothing wrong with standard therapy. Lots involved in making a decision like this besides the labs. Can you get there easily, (its an eight month treatment, almost weekly). You may or may not be able to work depending on your response to the meds and what kind of job you have. Expenses are not totally covered. Your comfort level with the docs.
Good luck with your eval and your decision.

IMWG Guidelines for SMM
Preventive clinical trials need to be considered forpatients with high risk smoldering myeloma.
Patients with smoldering myeloma with FLC ratio <0.125 or > 8 plus > 10% plasma cells in the marrow are at high risk of progression in the first 2 years following recognition.
These patients should be considered candidates for chemoprevention trials. However, off-study, observation is still the standard even in this group.

Wb-MRI in SMM
“End organ damage currently is the most important factor for the classification and the decision to treat systemically in monoclonal plasma cell disease. Therefore, serum calcium, renal damage, anemia, and bone destruction (ie, osteoporosis or focal lytic bone lesions) are the most important parameters (ie, CRAB criteria).”

Who and When to Treat
• Newly diagnosed patients with no evidence of evolving organ damage– Vaccinate– Observe at 3 month intervals– Offer E3A06
• Follow clonal proliferation based on increasing M-protein or FLC
• Follow for trends in organ damage • Marrow, kidneys, skeletal system
![Page 39: Case 1: Patient with high-risk smoldering myeloma – watch and wait or treat immediately?](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815167550346895dbf95d2/html5/thumbnails/39.jpg)
Should all high risk SMM patients be treated immediately?
• Not as standard of care• Determine what the patient wants
– Offer E3A06 or NIH CRd trial• Use best metrics for clone and organ damage
– Follow trends • Image appropriately
– MRI, PET/CT

Changing Landscape
• Updated IMWG guidelines needed
– for SMM clinical trials
• How rational are our definitions?
• How radically should they be changed?
• Should we
– redefine myeloma needing treatment?
– regroup plasma cell diseases?
• risk from clone and organ damage
• We cannot overlook the urgency of relapsed/refractory status as a major driver
