When using daratumumab in the setting of post-transplant red cell aplasia or post-transplant immune-mediated cytopenias, do you hold the drug for certain ANC parameters?
Typically, we do not hold until below ANC 500.
How do you approach steroid-refractory GVHD in patients who either cannot receive ruxolitinib or do not respond to ruxolitinib?
Both acute and/or chronic GVHD could be steroid-refractory. In patients with acute steroid-refractory GVHD, I would target therapy based on organ involvement. If skin is involved and the patient cannot take or get ruxolitinib, I would use ATG first, in particular if severe disease, but there is a nu...
What is your approach in a fit patient, advanced stage, bulky classical Hodgkin lymphoma who has decreased disease burden in areas but a persistent, hypermetabolic (Deauville 5) anterior mediastinal mass following two cycles of AAVD?
Biopsy!If persistent HL:I know it is only phase II data, but I've been impressed with the ORR and personal experience with pembro-GVD: Moskowitz et al., PMID 34170745.I hate radiating the chest, but one could argue that option as well.
How would you treat a locally-recurrent extraosseous (pulmonary) Ewing sarcoma?
It is possible to re-challenge the patient with the same regimen. Assuming EF and BNP are normal and can be followed, bolus Doxorubicin with Dexrazoxane would allow safe administration of additional doxorubicin. The alternative is to use high-dose Ifosfamide (14 g/m2/cycle). In the event of a good v...
In patients with severe hemophilia A on emicizumab for prophylaxis, in case of noncompliance leading to a lapse of more than 2-3 months off therapy, do you reload with emicizumab?
In general, you need to restart the four-week loading then follow with maintenance. First, you need to find out why they were noncompliant (e.g. did not like/could not do subcutaneous injections, did not work, always noncompliant). If they are planning to continue noncompliance, this is not a good ...
How do you discern whether elevated liver enzymes are from immunotherapy versus chemotherapy when a patient is on combination chemo/immunotherapy?
There is no consensus on the best method for distinguishing the cause of elevated liver enzymes in patients being treated with ICPi's when combined with various chemotherapies. Important considerations include time of onset, severity, and presence of hepatobiliary metastases. Hepatotoxicity from ICP...
Is cross reactivity low enough to try cisplatin as an alternative for patients who experience hypersensitivity reaction to carboplatin?
A couple of preparatory comments. First, there is a reasonable review recently published about platinum sensitivity and management questions related to this (Makrilia et al., PMID 20886011). The second comment is that platinum sensitivity reactions can be quite severe, and are relatively rare with <...
How would you approach an early stage II unfavorable Hodgkins lymphoma following 6 cycles ABVD with persistent Deauville 5 with negative biopsy?
This is an active disease and should be treated accordingly. I would not wait. RT is certainly option number one now, but the patient has a considerable risk for recurrence even after RT, since he/she has Hodgkin‘s that is not responding adequately to treatment. Continuing with ABVD in a patient who...
When do you refer patients for germline testing when somatic tumor testing is negative for actionable mutations?
Somatic (tumor-only) testing should not be used to conclusively rule in or rule out the presence of a germline pathogenic/likely pathogenic alteration. While most germline sequence alterations (point mutations, small insertions/deletions) will be detected on tumor-only testing, this may miss chromos...
Do you hold IV iron in the setting of active infection?
While there is no evidence of harm, there is enough conjecture about the danger to make it prudent to wait until infection is controlled. So yes, I do. Further because of the iron restricted erythropoiesis during infection, the efficacy is likely to be blunted.
