Do you do prophylactic LP/IT chemotherapy in high risk APML prior to starting consolidation?
Extramedullary disease such as CNS involvement is quite uncommon at diagnosis in acute promyelocytic leukemia (APL). However, it can be seen in patients with relapsed disease. Both isolated CNS relapse and CNS relapse associated with morphologic or molecular relapse can occur. Yet one has the impres...
What dose of radiotherapy do you use for low volume Castleman's disease?
Reports in the literature are varied in terms of radiation dose. For scenarios such as this with low volume disease, it is probably reasonable to consider the lower end of ranges reported by others to be successful, such as 30 Gy. Careful pathology review is important for these cases as well. One mu...
Do you check IGHV mutation status in patients with newly diagnosed CLL?
Yes. In the targeted therapy era, there are three factors that continue to have prognostic and therapeutic significance and should be checked: IgHV mutation status p53 aberrancy - requires both FISH for del17p AND mutation analysis for p53 Complex karyotype - can be done on peripheral blood or marr...
How do you approach patients who are inappropriately worried/fixated on a test result that is flagged as abnormal but not clinically significant?
This happens all the time now. I tell them that those results were flagged as outside the reference range (I don't use the term abnormal) but that they are not clinically significant. It does not always work if there is a patient who is super anxious or hyper-focused. Typically, if they need a lot m...
Would you radiate the thoracic duct for bilateral chylothorax in a hematologic malignancy with no discrete adenopathy?
We have done for adenopathy, which relieves obstruction and thus helps with drainage, but we don’t know how it would help in this situation.
Do you check LDH levels for patients with CLL who are asymptomatic and on surveillance?
I personally include LDH as part of my routine chemistry panel monitoring of CLL in surveillance for several reasons. Often, patients with CLL can show up with new anemia; in such cases, the differential diagnosis is autoimmune hemolytic anemia versus disease progression. An elevated, new LDH level ...
Do you see a role for omidubicel upfront in severe aplastic anemia for patients without a matched donor?
We typically use cord blood products if there is no available family member donor or reasonably matched unrelated donor. The use of haploidentical family donors is very effective, less expensive, and allows supplementation with CD34+ stem cell boosts if counts are suboptimal DeZern et al., PMID 3234...
How do you manage catheter-associated, upper extremity superficial venous thrombosis?
I manage catheter-associated upper extremity superficial venous thrombosis (SVT) conservatively with arm elevation, warm compresses, NSAIDs, and topical creams containing NSAIDs. Upper extremity SVT is primarily caused by indwelling intravenous catheters, so I do strongly recommend catheter removal ...
How long would you anticoagulate a patient with recurrent VTE who has ongoing risk factors for intracranial bleeding?
In general, my preferred agent outside of the inpatient setting in patients with a risk of intracranial bleeding is LMWH. In the inpatient setting, utilizing a bivalirudin or heparin gtt is most appropriate. I would monitor carefully, including potentially imaging 24 hours after the therapeutic anti...
Can AMPLIFY data be extrapolated to use of other BTKi's in combination with venetoclax or would you only ever use acalabrutinib/venetoclax in first line?
I prefer NOT to extrapolate results, given that BTKis have unique spectra of kinase activities ("kinomes"), different PK/PD properties (such as half life), different adherence rates and dosing schedules, and have different synergistic (especially in a complex immune context that we are committing to...
