How would you advise a younger patient with residual/recurrent optic nerve meningioma, proceeding with radiotherapy, about the risks of malignant transformation or induction of other brain malignancies because of radiation?
The risk of malignant transformation of an optic nerve sheath meningioma (ONSM) after RT appears to be remarkably low, much lower than the risk of blindness from an untreated, progressive ONSM. In a younger patient, I would lean toward RT for patients with imaging progression or early visual loss, ...
How will you utilize the PARADIGM study results from ASH 2025, comparing azacitidine/venetoclax to intensive induction chemotherapy for fit patients with newly diagnosed AML?
It was very exciting to see PARADIGM presented as a plenary at ASH, and I look forward to the manuscript! Interpreting the findings in the context of the enrolled patients is very important. The median age of enrolled patients was approximately 65 years in both arms, and ~75% of enrolled patients ha...
What factors should be considered when deciding whether to omit radiation in pediatric/AYA patients receiving N+AVD, particularly regarding long-term outcomes and second malignancy risks?
Based on the early data from S1826, it appears that radiation can be omitted if end-of-therapy scans (after 6 cycles of therapy) show metabolic remission of disease. The ability to limit RT to 1% of patients is encouraging for potential reduction in late effects such as cardiovascular disease and SM...
What factors determine whether a patient in their 20s with a new oncologic diagnosis is better served by an adult or pediatric center?
It's been 30 years since Dr. Archie Bleyer first pointed out that adolescents and young adults had not enjoyed an increase in survival over a 50-year period that had been seen in pediatric and older adults with cancer.Since then, every study has shown superior outcomes for young adults treated at pe...
In pediatric patients with Hodgkin lymphoma who have a partial response after chemotherapy and multiple disease sites above and below the diaphragm, how do you approach radiotherapy planning considering cumulative dose and toxicity?
RT dose and target volume in pediatric Hodgkin lymphoma are determined according to the systemic therapy protocol being used. For example, your case suggests a patient with Stage III or IV disease. In the COG study AHOD1331, patients received either Bv-AVE-PC or ABVE-PC systemic therapy x 5 cycles a...
What areas do you treat with RT for an intermediate or high risk pediatric Hodgkin Lymphoma with a slow early response?
For pediatric Hodgkin lymphoma, radiation fields are really based according to the treatment protocol. If the patient was being treated per AHOD 0031, then the radiation fields would include all sites of initial involvement, assuming they don't meet the criteria for omission of RT (RER and then a CR...
What is the optimal timing for PET/CT to assess disease and treatment response with nivo + AVD?
The S1826 study did not require interim imaging. Despite this, I routinely order an imaging test prior to cycle 3, day 1 for patients on the N-AVD regimen. In most cases, I order PET/CT scans. I continue therapy in patients with a Deauville score of 4 or less (partial or complete response) rather th...
How would you work up a mildly neutropenic patient (ANC >800) with family history of neutropenia and personal history of occasional mouth sore?
The first question is whether to evaluate the neutropenia at all. With ANCs >800 and only occasional mouth sores, is a diagnosis necessary, and should the term “neutropenia” be used at all? If the family’s origin is in a part of the world where the Duffy null phenotype is common (e.g. Africa, parts ...
What are your top takeaways in Lymphoma from ASH 2025?
Fixed-duration versus continuous targeted treatment for previously untreated chronic lymphocytic leukemia: Results from the randomized CLL17 trial — This trial may change practice by using the combination of BTK-I and Ven without CD20 antibodies. This time-limited option led to MRD, and I would expe...
How do you manage patients desiring home hospice but with severe thrombocytopenia and/or anemia due to advanced malignancy?
As a pediatric hematologist/oncologist and pediatric palliative care physician, I can only speak to our approach with children, which may be quite different than the adult world. In our community, we are not able to provide blood or platelet transfusions in the home. For children who are profoundly ...
