In a patient with amyloidosis and abnormal liver function but child Pugh A, would you still proceed with SABR for a liver metastasis?
No great data regarding the impact of amyloidosis on liver tolerance, but if the patient was a CP Class A patient, I would feel comfortable offering SABR for a liver metastasis.
What is your approach to ESA use in patients with ESKD and active malignancy on treatment?
Patients can receive ESA’s and keep hgb goal at 10. Would discuss this with an oncologist and get clearance and after a hematological workup is also attained.
How would you manage anticoagulation in a patient with acute MI or PE with prolonged aPTT due to congenital factor XII deficiency?
You can monitor anti Xa levels.
Would an MPL variant mutation of unknown clinical significance be considered diagnostic of essential thrombocytosis in a patient with longstanding elevation in the platelet count, and for whom all secondary causes have been excluded?
A bone marrow biopsy should be performed if not already done to complete diagnostic work-up for an MPN. If the MPL variant is truly of unknown significance, then that alone is not diagnostic of an MPN. The WHO 5th edition criteria for ET diagnosis are summarized in Loghavi et al., PMID 38043791 and ...
What is your perioperative approach to holding and restarting hydroxyurea in patients with essential thrombocythemia?
I would like to rephrase the question since as written, the assumption is that hydroxyurea is a preferred therapy for ET, when any careful reading of the literature will show that there is no proven rationale for using chemotherapy of any sort routinely in ET. There is no association between the pla...
When do you re-image patients with a diagnosis of venous sinus thrombosis?
My practice is to perform early reimaging, typically at around 2 weeks, before transitioning from parenteral anticoagulation to oral anticoagulation. This early reassessment is important as recanalization processes begin early and are linked to clinical outcomes. Subsequent imaging at 6 months is al...
How do you manage thrombocytopenia when radiating the spleen?
Radiation oncologists are occasionally asked to see patients with symptomatic splenomegaly (early satiety, dyspnea, and pain) and evaluate for radiation therapy. Many such patients have non-functional bone marrow from diseases such as primary myelofibrosis. This leads to extramedullary hemoatopoiesi...
How is transferrin saturation a reliable indicator for any parameter if serum iron is not reliable?
The question is a very good question. The Fe/TIBC must be drawn on an overnight fast including any vitamin pills containing iron. Otherwise, the serum iron is speciously elevated which in turn speciously elevates the TSAT. If those conditions are met, the TSAT is as good as the transferrin receptor ...
What subset of sickle cell disease patients are you offering sickle cell disease gene therapy?
All patients with Hgb SS and patients with Hgb SC who have had any significant complications, excluding chronic pain.
When do you refer AYA patients with newly diagnosed severe aplastic anemia for transplant?
In a young person, my first thought is to obtain telomere lengths to be sure he/she does not have a telomeropathy. This has significant implications both with and without transplantation. Certainly, if telomeres are short, allogeneic transplantation is preferred since there is less likelihood of res...
