How long do you treat with IMID in a case of smoldering multiple myeloma?
I have not yet adopted use of lenalidomide for SMM, as I believe in the future, we will do away with the definition of SMM—patients either have MGUS which is observed, versus MM which requires the standard platform of myeloma treatment. This will be accomplished with a better molecular understanding...
Do you check LDH levels for patients with CLL who are asymptomatic and on surveillance?
I personally include LDH as part of my routine chemistry panel monitoring of CLL in surveillance for several reasons. Often, patients with CLL can show up with new anemia; in such cases, the differential diagnosis is autoimmune hemolytic anemia versus disease progression. An elevated, new LDH level ...

Would you use routine PET scans after two cycles of R-CHOP to guide first-line treatment de-escalation in low-risk (aaIPI = 0) DLBCL patients?
This phase III trial suggests that in very low-risk limited-stage DLBCL (aaIPI = 0), patients who achieve a negative PET after two cycles of R-CHOP can safely receive only four total cycles instead of six, with similar 3-year PFS (92% vs 89%) and less toxicity. However, the results apply to a highly...

When do you order genetic studies such as comparative genomic hybridization for melanocytic lesions?
In my practice, I confine copy number alteration studies (SNP array testing) for cases where the biological potential of a melanocytic proliferation is in question. I do not perform the testing if the case is diagnostic histopathologically and/or immunohistochemically of a nevus or melanoma.The seco...
How do you approach relapsed idiopathic HLH?
This question is quite non-specific - the answer depends very much on the specific context (child, adult, relapsed after what treatment?) and as such, can only be answered in broad strokes.First, ensure that it is truly idiopathic – check EBV, CMV viral loads, and other viral/infectious triggers as ...

Do you initiate anticoagulation prophylaxis for pediatric patients with vascular compression secondary to solid tumor/lymphoma?
It is an interesting question, but lacks critical details. Of course, most cancers are prothrombotic, and anticoagulation can have risks: Is it arterial or venous compression? Complete obstruction? Acute or chronic? Collaterals? Is it compromising an organ? Is thrombus seen, or is there blood flow?...
Is there any role for bisphosphonate or alternative bone-modifying agents use in SMM in the absence of other indications for its use?
The short answer is no, unless the patient has an indication like osteoporosis. Bisphosphonates have been evaluated in smoldering multiple myeloma in studies performed over 10 years ago. Treatment with pamidronate (D’Arena et al., 2011) or zoledronic acid (Musto et al., 2008) did not affect the time...
