How do you choose between axicabtagene ciloleucel and tisagenlecleucel in patients with follicular lymphoma for whom you are recommending CAR T-cell therapy?
This is an area of uncertainty. There are no head-to-head data to bring to bear, of course (and, if there were, you probably wouldn’t need to ask). The toxicity profile of the two cells is clearly different, with lower rates of severe toxicity with tisacel than with axicel. As neither product has be...
What is your approach to MRD testing in the frontline treatment of multiple myeloma?
Outside of clinical trials, I am not ordering MRD testing for patients in the newly diagnosed setting, regardless of transplant eligibility. While there are substantial data showing that MRD status correlates with survival outcomes (e.g., Munshi et al., Blood Adv 2020), there is a dearth of informat...
How do you manage grade 1-3A Follicle Center Lymphoma of the lower female genital tract, presenting with a cervical mass?
I would treat this with 12 x 2 Gy. Indeed, fertility preservation will be an issue here. Depending on the size of the lesion, if the ovaries can be spared, then 24 Gy delivered to the cervix/uterus may still allow for a pregnancy with a favorable outcome. Another experimental approach, if the patien...
What hemoglobin level prompts you to start erythropoietin in a patient with low-risk MDS?
Depending on the patient's symptoms and clinical context, I will either start an ESA when the patient starts becoming transfusion-dependent (Hgb < 8 g/dL) or, if the patient is not transfusion-dependent, but still symptomatic from anemia, I will start the ESA when their Hgb is < 10 g/dL. Prior to in...
How soon after CAR T-cell therapy can salvage radiation be delivered?
This is another important question. In our practice, the earliest we have treated patients is after their first post-CAR-T PET/CT at day 30. An abstract presented in an oral presentation at this year's ASTRO meeting by Dr. @Dr. First Last describes that radiation to sites of incomplete response at t...
How would you approach a patient with limited stage SCLC who progressed immediately after completing chemoradiation with brain metastasis?
For 1-10 brain metastases from SCLC, consider the NRG CC009 clinical trial randomizing between SRS and hippocampal-avoidance WBRT!
Is there an optimal salvage radiation dose for relapsed post-CART disease?
While there is not enough data to definitively recommend a specific dose, we feel an EQD2 > 37.5-40 Gy is desirable for patients with limited residual or relapsed disease post-CAR T-cell. Our commonly recommended fractionations include 37.5 Gy in 15 fractions, 40 Gy in 15 fractions, and 40 Gy in 20 ...
In a patient with recurrent fibrolamellar HCC a year after upfront resection (previously refused adjuvant therapy) with a solitary abdominal mass, would you offer neoadjuvant therapy to assess response?
Recurrent disease is the best care for under clinical trials for FLC. There are not many, sadly because of limited support. But there are some, like NCT03860272.
How do you approach a patient with newly diagnosed high-grade osteosarcoma who received maximum cumulative dose of doxorubicin for a soft tissue sarcoma 10 years earlier?
Some chemo is better than no chemo for osteosarcoma.That is what is known. After the first randomized study establishing that chemo was effective at improving survival for OS, all subsequent randomized studies have been statistical ties. No regimen or schedule or dose or drug has been proven to be b...
Do you recommend sperm banking for males prior to undergoing radiation?
To the first question in the prompt, I would recommend sperm banking for any patient who was receiving a sufficiently high radiation dose to the testes and desired fertility preservation. In my practice, this are few patients, although it is an important consideration for younger patients. To the se...
