In transplant-eligible, fit patients with primary refractory myeloma, what is the optimal timing for stem cell collection?

We know the longer we expose patients to lenalidomide, the harder collection will be. Would you collect now or switch to an alternative regimen to achieve VGPR or response prior to collection? Any preference on KPd versus DPd or alternative regimen?

In fit patients with less than a partial response to induction therapy, i.e. primary refractory, the optimal timing for stem cell collection is NEVER. If they don't respond to three drug induction (proteasome inhibitor + IMiD + steroid), they are unlikely to respond durably to a standard high dose m...

I will take a different tactic in these primary refractory disease cases.

I typically employ a VD-PACE like regimen and give for 2 cycles. Then use the second cycle as part of chemomobilization for stem cell collection, followed by high dose melphalan and stem cell rescue. After transplant, I then w...

Adding an updated response as requested by theMednet editorial team :) I agree with everything in @Dr. First Last's response from 3 years ago. For patients with primary refractory myeloma, even collecting stem cells is probably low-yield especially since it's not benign. And while continued len expo...
