What is your approach to initial management of patients with suspected or confirmed primary cutaneous CD8+ positive aggressive epidermotropic T- cell lymphoma (PCAECTCL)?
PCAECTCL is an exceptionally rare and clinically aggressive subtype of cutaneous T-cell lymphoma, characterized by a rapidly progressive course, ulcerated or necrotic skin lesions, and early dissemination to extracutaneous sites. Due to its rarity and lack of standardized guidelines, management is l...
In a newly diagnosed elderly patient with AML who harbors an IDH1 mutation, would you treat with upfront with ivosidenib/HMA or would you proceed with venetoclax and HMA as your first line treatment?
For me, the decision whether to treat this patient with IDH1 inhibitor monotherapy (ivosidenib) vs. venetoclax/HMA depends on how fit this patient is and his/her desire for aggressive therapy and inpatient vs ambulatory care. Prior data suggests very high response rates (90-100%) following venetocla...
How would you manage a solitary, painful, lytic bony lesion in a patient with negative PET/CT but bone marrow biopsy confirmation of multiple myeloma?
This is a palliative scenario, but the approach may differ based on the clinical circumstances. If Heme Onc is planning on administering systemic therapy, then a short course of palliative RT to expedite pain control would be appropriate. Treatment of many sites (e.g., femur) can be done very quickl...
How do you choose between liso-cel and axi-cel in patients with early relapse DLBCL for whom you are recommending CAR T-cell therapy?
Axi-cel and liso-cel are anti-CD19 chimeric antigen receptor (CAR) T-cell products approved for primary refractory or early relapsed (<1 year from initial chemoimmunotherapy) diffuse large B-cell lymphoma (DLBCL). Both products exhibit excellent efficacy (overall response rates >80%) and are potenti...
How would you treat a stage I fully resected double hit DLBCL?
In patients with fully resected DLBCL, I still give chemotherapy. That also applies to double-hit lymphomas. Limited stage DHL does not seem to have a poorer prognosis than non-DHL, and intensive regimens do not make a difference. I would treat with RCHOPx3-4 cycles.Torka et al., PMID 31945157Lue et...
How would you manage relapsed DLBCL in a patient who received second line CD19 CART treatment?
With commercial CD19 CAR-T therapy moving into earlier lines of therapy, post-CAR-T relapses are now more common. There are still many options depending on what first-line/bridging therapy was given, CD19/20/30 expression, and patient preferences. I always get a biopsy if feasible to confirm relapse...
How have the results of the SUNMO trial with mosunetuzumab/polatuzumab vedotin impacted your treatment choices for transplant ineligible relapsed/refractory DLBCL?
The SUNMO trial results have provided another option for patients with relapsed and/or refractory disease who aren't fit enough for more intensive therapy, whether it be salvage + ASCT for relapsed or CAR-T/bispecific + CIT for those with refractory disease. As well, the regimen is likely to have le...
How do you manage erythrocytosis secondary to sotatercept for patients with PAH?
I have not done that yet, but I have let Hgb drift up to 18-19 and monitor the patient closely. I lower the dose to 0.5 or even 0.3, if Hgb is high at baseline, then start and stay at 0.3 before I increase. I will consider phlebotomy if the above options are not available.
In an adult patient with asymptomatic, isolated neutropenia in whom you suspect a Duffy null phenotype, at what ANC or in what situations would you do a bone marrow to look for other etiologies of neutropenia?
What a great question! Happy to answer. As you know, as many as 60% of individuals who have the Duffy null phenotype will have an ANC that is lower than the lower limit of normal in many labs BUT as you also know, the total body (in circulation + in tissues) neutrophil count in such individuals is n...
When would you consider use of emapalumab for HLH/MAS?
The FDA has approved emapalumab for familial HLH. For secondary HLH/MAS, I typically begin with anakinra (100 mg q 6 hrs for those 40 kg or more). If this is not enough and if CXCL9 (I send on day one to have the data available) is notably elevated, then consider adding emapalumab. Alternatively, a ...
