In the post Covid era, could the ILROG hypofractionated regimens (published as "emergency guidelines" for lymphoma) be considered as standard of care for ISRT?
In palliative settings, we have utilized hypofractionated regimens in hematologic malignancies for decades. Examples include 4 Gy X 1 for follicular lymphoma, 4 Gy X 5 for myeloma, 3 Gy X 10 for DLBCL, and 4 Gy X 2 for mycosis fungoides. In select circumstances (both before and after COVID-19), I ha...
Do you check the Duffy-null phenotype before starting azathioprine and in which patients?
I personally do not check the Duffy antigen prior to starting azathioprine. I do check TMPT levels on all patients prior to starting it to help determine initial dosing.
How would you manage a patient with HbSS and severe pulmonary hypertension on home oxygen?
This patient should be referred to a specialist in pulmonary hypertension in sickle cell disease for right heart catheterization and aggressive management of the pulmonary hypertension. As described, the patient is not a good candidate for lung transplant or gene therapy.
How would you approach the staging and treatment of extranodal marginal zone lymphoma of left and right lacrimal gland?
This entity is described in literature as "ocular adnexal lymphoma". I usually screen those patients for Chlamydia infection and would empirically consider a 3-week course of doxycycline especially if the disease is indolent behaving clinically and there is prior serologic evidence of Chlamydia infe...
In which patients with MGUS do you recommend a kidney biopsy to evaluate for MGRS?
If a patient has unexplained renal disease, and this could be interstitial or glomerular, and an MGUS, I strongly consider it. I typically try to get heme to do a bone marrow biopsy first because their findings may obviate a renal biopsy if they find something (although sometimes they may find low-g...
What treatment options do you consider if eosinophilia with end organ dysfunction persists with q8 week dosing of benralizumab and you can't obtain approval for q4 week dosing?
Depending on the degree of eosinophilia and end-organ dysfunction, if the patient is not already on oral steroids, they probably should be pending a new plan for a steroid-sparing agent. Is the diagnosis more consistent with HES or EGPA? Has the patient failed mepolizumab 300 mg? There is good data ...
How would you treat an elderly, transplant-ineligible patient with recurrent DLBCL?
There is no single standard of care in the treatment of transplant-ineligible relapsed or refractory DLBCL in the second line. Many regimens would be considered relevant considerations here, including rituximab, gemcitabine, and oxaliplatin; bendamustine and rituximab; rituximab and dose-adjusted EP...
In a patient with type I von Willebrand disease who is pregnant and at increased risk for preeclampsia, would you recommend treatment with aspirin?
Yes, and is tolerated well.
When would you initiate exchange transfusion in babesiosis and significant hemolysis?
There are no studies that answer this question. Some people have extrapolated from the use of exchange transfusions for severe malaria to consider using this treatment with babesiosis, another intraerythrocytic protozoan infection. Unfortunately, though there are some studies on malaria, the results...
How do you choose which BTK inhibitor to use in NHL?
At this point, I use very little ibrutinib. If I need CNS penetration, ibrutinib has a track record there. Otherwise, I have pivoted to acalabrutinib and zanubrutinib. I typically will pick by indication - acala for CLL and zanu for WM/MZL. In MCL or likely soon in CLL, I am not entirely sure how to...
