Do you continue daratumumab beyond 24 months in first line treatment of amyloidosis?
This is an important and common clinical question, and one for which prospective data are currently limited. For background, the ANDROMEDA clinical trial (Kastritis et al., PMID 34192431) demonstrated that the addition of daratumumab to cyclophosphamide, bortezomib, and dexamethasone (CyBorD) signif...
When would you use AVD + brentuximab instead of ABVD for newly diagnosed stage 3 or 4 Hodgkin lymphoma?
By reducing the risk of primary treatment failure from 23% to 18%, the ECHELON-1 study demonstrated that compared to ABVD, AVD + brentuximab vedotin reduces the risk of primary treatment failure by about 25% for patients with advanced-stage classic Hodgkin lymphoma. If given with prophylactic G-CSF,...
Are there still clinical situations in which you deliberately treat patients with a DOAC besides apixaban?
Thank you for your question. Apixaban has been my preferred agent for a long time for patients requiring therapeutic anticoagulation. Apixaban’s lower bleeding risk was shown prior to and now has additional evidence to support this with the COBRRA trial. The risk is also ameliorated by the safety in...
Can aplastic anemia present with multiple infiltrative bone lesions, such as in the spine and pelvis?
It is exceedingly unlikely that such bone lesions are due to aplastic anemia. AA is the absence of hematopoiesis, so there is no mechanism for bone lesions to be present.
In what scenarios do you use a chromogenic factor X assay in adjusting INR goals for patients on warfarin?
I do not use this method. It has been suggested that such assays be used in patients with lupus-type inhibitors who have significantly prolonged prothrombin times at baseline. In this setting, if the INR is "therapeutic," one would confirm an adequate warfarin effect if the factor X activity was in ...
Do you offer enasidenib with azacitadine in AML with an IDH2 mutation for patients ineligible for intensive induction chemotherapy?
I typically do not give enasidenib with azacitidine upfront for patients with AML with IDH2 mutation and ineligible for intensive induction chemotherapy. Based on the results of the VIALE-A study (DiNardo et al, NEJM 2020), I usually give venetoclax with azacitidine to those patients. In addition to...
Are there any alternative, hypofractionated RT courses for patients with DLBCL that can be used during the COVID-19 pandemic?
ILROG recently came out with guidelines pasted below: Synopsis of ILROG Recommendations for Administering Radiotherapy for Hematological Malignancies During Emergency Conditions of the COVID-19 Pandemic • We are facing an increased demand for RT to substitute or complement systemic therapy deemed i...
What is your preferred 1L treatment for newly diagnosed Del(17p)/TP53 mutation, High-Risk CLL?
For patients with TN-CLL with TP53 aberration, the treatment options are usually based on patient factors. If a patient is a candidate for combination therapy, I prefer to treat them with uMRD-guided BTKi+BCL2i ± CD20 mAb. I only add a CD20 mAb to patients with no history of frequent infections and ...
In a patient who has been receiving 1L Ibrutinib for TP53+ CLL for years with complete hematologic response but detectable MRD, is there any role to switch to the novel BTKi agents given better PFS?
There are a couple of features to this question that need comment. First, the goal of therapy with a single-agent BTKi, regardless of ibrutinib, acalabrutinib, zanubrutinib, or pirtobrutinib, is NOT to achieve undetectable MRD. Very few patients will achieve this milestone due to the drug's MOA. BTK...
Is there any indication for IVIG in immunocompromised patients with only decreased IgM and/or IgA levels?
Nope. IVIG preparations contain IgG not IgA or IgM. Low serum IgA may or may not be associated with low IgA levels in mucosal surfaces leading to a risk of local infections. Low levels of one or both may be asymptomatic but in the right setting might suggest a need for evaluation of plasma cell dysc...
