What is your approach to bone imaging in MGUS?
Excellent question. For low-risk MGUS (M-spike <1.5 g/dL, normal serum free light chain ratio, and an IgG type protein), it is reasonable to forego any bone imaging in the absence of any relevant bone-related symptoms. The rate of bone involvement in patients with an M-spike of 1.5 g/dL was noted to...
How do you approach the management of a patient with symptomatic iron deficiency anemia who is intolerant of iron?
Oral iron will not work. I would bet my last dollar there was no anaphylaxis but rather an imprudently treated minor infusion reaction which is the cause of ostensible “anaphylaxis” over 99% of the time. You can’t verify that it was real because I can assure you: It was not. They did not do a trypt...
Do you routinely refer young patients with iron deficiency anemia for GI evaluation?
The answer is no, I do not. However, if after iron repletion deficiency persists, then I do. But as for pregnancy, unless there has been a precipitous and proven drop, I would definitely not do a GI workup during pregnancy.

How would you manage symptomatic iron deficiency in patients with PV on frequent phlebotomies?
While iron deficiency by itself is not harmful, if someone has symptomatic iron deficiency, you could consider them intolerant to phlebotomies, and start a cytoreductive agent. Then, over time they can replete their iron stores. In some patients who are very symptomatic from their iron deficiency, I...

For a patient with NSCLC harboring an EGFR or ALK mutation that transforms into SCLC, would you add immunotherapy to chemotherapy or avoid immunotherapy given the tumor's EGFR/ALK origin?
I typically avoid immunotherapy and continue the targeted therapy, such as osimertinib, with the chemotherapy.
For a patient with May-Thurner syndrome and DVT, would you recommend anticoagulation for 3-6 months or indefinitely?
This is a very good question, there is little data on this and there are only a few case series. One case series of 8 patients showed a 25% risk of recurrence in one year with May-Thurner syndrome but too small of a sample to really know what the risk is, plus this probably included a heterogenous m...
For patients with newly diagnosed VTE on IV heparin planned for transition to DOAC, would you start at the loading or maintenance DOAC dose?
Agree with Dr. @Dr. First Last. In the clinical trials that led to rivaroxaban and apixaban approval, many patients had 2 days of injected anticoagulant first to arrive at successful outcomes leading to DOAC approval. I suggest IV heparin until hemodynamically normal (for PE), sq LMWH for a dose or ...
