What is the recommended radiation treatment volume for a patient with orbital DLBCL who achieved a CR to chemotherapy?
I suggest consulting the excellent guideline from the ILROG. There is a difference between Primary Intraocular Lymphoma and Orbital (Ocular Adnexal) Lymphoma. The guideline also describes which patients can be managed without irradiation of the entire orbit.
What is your approach to BK hemorrhagic cystitis not responding to cidofovir?
BK hemorrhagic cystitis can range from completely asymptomatic infection (with positive BK viremia and viruria by PCR) or grade 0 to massive macroscopic hematuria requiring instrumentation for clot evacuation and urinary obstruction requiring bilateral nephrostomy tubes for urine diversion (grade 4)...
For a patient with PE undergoing procedures like port placement in the first month, how do you manage anticoagulation?
Due to their convenience, efficacy, and safety, I think direct oral anticoagulants (DOC) are the agents of choice for most cases of PE, DVT, or chronic prophylaxis. As per the package insert for Apixaban, for moderate or high risk invasive procedures, stop 48 hrs in advance, and for low risk, stop 2...
Which patients with acute promyelocytic leukemia do you consider maintenance after completing consolidation?
Before we address the role of maintenance in APL, several principles are important to note. First, APL is now a highly curable disease with contemporary therapeutic strategies. Second, we now divide patients into low-risk and high-risk based solely on the presenting WBC (< or =10,000/uL vs >10,000/u...
How do you advise patients with sickle cell disease on contraception?
According to both the "ASH Pocket Guidelines" and the National Heart Lung and Blood Guidelines for health maintenance in Women with sickle cell disease, progestin only and barrier methods of contraception are the preferred recommendations for contraception. Combined hormonal agents can be considered...
How do you approach the management of GVHD prophylaxis in the setting of severe infection?
GVHD prophylaxis the 1st ~ 3 months after alloSCT is paramount and immunosuppression withdrawal might cause GVHD which can in turn exacerbate or cause infection given the need of corticosteroids to control it. Having said that, case-by-case management is important. As an example, alloSCT using a PTC...
Would you consider thrombophilia testing in a pregnant patient with VTE?
I would not check antiphospholipid antibodies in a pregnant woman with thrombosis unless she had a history of autoimmune disease or other concerning findings. However, if it were checked, I would make sure that it is a true positive. DOACs often cause a false positive LAC. I have had patients with f...
How do you titrate hydroxyurea in the management of myeloproliferative neoplasms?
It certainly depends on the situation, but for most patients, the default is to start at 500 mg PO daily and make adjustments every 1 to 2 weeks based on the counts to get to the therapeutic targets.
Would you consider clearing a patient with essential thrombocytosis for a kidney donation?
For brevity, I am assuming that the patient is already medically approved for surgery and organ donation, and I will focus on the clinical significance of the essential thrombocytosis (ET) with regard to both. I am also going to assume that the patient actually has ET, and not masked polycythemia ve...
How would you approach a young patient with a history of APLS and VTE, desiring hormone replacement therapy after oophorectomy?
I think the answer is not straightforward. What APLAs are positive and what was/is the titer? Were there other risk factors at the time of the clot (smoking, oral contraceptives, etc...) My general recommendation would be to avoid estrogens in patients with APLAs. I can imagine a scenario where the ...
