Should extra precautions be taken for pediatric oncology patients in light of the recent COVID-19 outbreak?
I have not personally seen cases. This is not surprising, however, because our patient population is more susceptible to severe outcomes from respiratory infections. This is compounded by weakened immune function and, for some patients, cardio respiratory damage.
How should you manage a pediatric oncology patient who has an ANC > 500 and a normal chest x-ray but is confirmed to be infected with COVID-19 and is immunosuppressed from chemotherapy?
The treatment for pediatric patients with cancer who develop COVID-19 is very poorly defined. The risk of severe disease is unknown because although adults with cancer appear to have worse outcomes than those without, non-immunocompromised children seem to have few severe outcomes from the disease a...
At what cumulative anthracycline dose is it recommended to use dexrazoxane for cardioprotection?
Typically considered in patients with anticipated >300 mg/m2 doxorubicin, as has been mentioned, which is most commonly seen in patients with sarcoma or recurrent lymphomas. Great discussion re: evidence and considerations in this piece in JACC Cardio-Oncology Upshaw et al., PMID 38773999.In practic...
What is your approach to optimizing pre-operative hemoglobin in patients with sickle cell disease?
This is always a question that has to be hyper-individualized. The research, and therefore the associated professional guidance, is thin. The American Society of Hematology (ASH) 2020 Guidelines for Sickle Cell Disease: Transfusion Support and the NHLBI Expert Panel Report (2014) are the only profes...
How do you counsel families of prepubertal girls with an oncologic diagnosis about cryopreservation of ovarian tissue?
One of the biggest current issues with ovarian cryopreservation (OTC) in the US is that there is no consensus yet about who should receive OTC, and practice varies across the country. In addition, many patients are diagnosed and treated at centers that do not have oncofertility programs and do not o...
Do you offer IV iron first line to women with iron deficiency anemia from heavy menstrual bleeding?
I offer first-line IV iron because oral iron cannot keep up with the losses from heavy menstrual bleeding, and the majority can't tolerate it. I routinely give a gram of LMW iron dextran in one hour, Feraheme (not ferumoxytol generic) 1,020 mg in 30 minutes, or ferric derisomaltose 1 gram in 30 minu...
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...
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...
What is the expected timeframe for the development of radiation myelitis and therapies that have helped with neurologic symptoms?
The incidence and the timeframe of the development of radiation myelopathy are influenced by total radiation dose, radiation dose per fraction, time between courses of radiation, and associated chemotherapy or immunotherapy. Older age, the presence of diabetes, and previous exposure to radiation are...
What is your treatment approach for a pediatric patient with H3K27M-mutant diffuse midline glioma following progression after radiation therapy?
First, if the patient is at least six months from initial radiation and has had a reasonable initial response, reirradiation is the best proven treatment for recurrence. We would also encourage enrollment on a clinical trial (the DMG National Tumor Board is a helpful resource for determining for whi...
