What would be your recommended regimen for an AYA patient with relapsed mediastinal pure seminoma, with relapse 20 months after completion of BEP?
Mediastinal seminoma is rare and has a high cure rate with chemotherapy alone (BEP x3). I would refer a patient like this to a high-volume center. Treatment options are high-dose chemotherapy followed by ASCT vs. resection. This should be a tumor board discussion. Despite limited data and the interv...
What would be your next line of treatment for disease control in a pediatric patient with metastatic hepatocellular carcinoma in partial response after multiple therapies?
Dear Dr. @Dr. First Last, Does the patient have an underlying hepatopathy (guessing yes, given the presence of varices)? And how old is the patient? Also - what was the AFP at diagnosis and what is it now? And what is the underlying liver function like? Final question - has the tumor been sequenced ...
What is the risk of secondary malignancy and/or conversion to MPNST for patients with NF-1 who undergo radiation?
Broadly speaking, this is certainly a possibility and this has been a reason why the community has triaged the application of radiotherapy to more high-risk cases (Williams et al., PMID 19117870). Just playing out the numbers independent of the application of radiotherapy, 100% of NF1 patients will ...
For which pediatric oncology patients do you start bacterial prophylaxis, inpatient or outpatient, and what is your antibiotic of choice?
Bacterial prophylaxis in pediatric oncology patients should be guided by the intensity of treatment, depth and duration of neutropenia, and individualized risk for invasive infection. Current evidence and expert consensus support targeted prophylaxis in children with the highest risk of life-threate...
What chemotherapy regimen would you use for a testicular cancer patient in need of BEPx3 but unable to use platinum based chemotherapy regimen due to cochlear implants?
To be succinct, the correct answer is BEP x 3 if he wants the therapy that would achieve optimal cure rate. If disease is limited to retroperitoneal nodes, especially if < 3 cm is the largest node and normal postorchiectomy, serum hCG and AFP, RPLND would then be the preferred option.
Are there any unique considerations for treating pediatric high grade glioma?
Trial availability, disease extent, age, specific molecular alterations, and family history should likely all play a role in choosing the most appropriate treatment paradigm.It’s expected that most future studies in pediatric high grade glioma will be stratified by their nascent biology, given that ...
When do you consider testing with stroke gene panels in young stroke patients?
Broadly, I ask for genetic testing only when I have a specific diagnosis in mind. This testing is not routine in my practice. Examples are: A patient is referred for white matter lesions found on brain MR and a transient neurological episode. The question of CADASIL(NOTCH-3) or related disorders is...
Is there any benefit of using aspirin to mitigate VTE risk in testosterone-induced polycythemia?
Erythrocytosis is a common adverse effect of testosterone therapy, and results from several studies suggest an association between elevated hematocrit (Hct) and risk of VTE (Braekkan et al., PMID 19833630; Ory et al., PMID 35050717). There is currently no data to support the routine use of aspirin o...
What is your approach to an infant (<12 mo) with new onset petechiae and thrombocytopenia, with labs consistent with ITP?
In an older (1-6 year old) child with apparent ITP, less work up might be needed. While many tests are possible, in this case, labs consistent with ITP, I would interpret as including a CBC otherwise normal for age without blasts on a smear (if this is not true, the differential is much wider). If i...
Do you recommend salvage radiation therapy to limited recurrent Ewing's sarcoma bony lesions?
Depending on the age of the patient, size, and location of the tumor, SBRT is often an attractive option for re-irradiation for a limited volume recurrence from Ewing sarcoma that failed to respond to prior conventional treatment. There is data from Mayo Clinic (Brown et al., PMID 25548538) and MSK ...
