Can aplastic anemia present with multiple infiltrative bone lesions, such as in the spine and pelvis?
There are several studies showing diffuse hypointense pictures with an infiltrative-like pattern on MRI in aplastic anemia and MDS. Some aplastic anemia and refractory cytopenia of childhood show patchy pattern of hematopoiesis with some regions having increased fat fraction and some remnants of hem...
Do you modify dosing and monitoring of Lu-177–PSMA therapy for patients with prior large-field RT involving substantial active marrow compared with patients who only had focal bone SBRT?
No, we do not modify dosing and monitoring of PSMA therapy with prior large-field RT. In the VISION trial, the vast majority of patients were heavily pre-treated, presumably many with pelvic radiation for definitive treatment or treatment for bCR prior to metastasis. Assuming that the patient had ap...
How would you manage an isolated nodal recurrence of breast cancer in a patient with a prior history of mantle-field radiation?
Nodal recurrences, especially in unresectable regions, are especially challenging cases in the context of reRT. At a high level, the first thing to think about is resectability. If resectable, the usual approach is surgery, then adjuvant RT to unirradiated areas, and adjuvant chemotherapy. If unrese...
How does one interpret the LUMINA trial in the FLORENCE APBI ERA?
This is a common scenario. My practice is to discuss this with the patient. I discuss 5 fraction PBI or 5 fraction WBI depending on the scenario, as well as endocrine therapy and the differences in toxicity profiles. Given compliance rates of 50-60% with endocrine therapy long-term, many patients pr...
Would you offer other antibody-drug conjugates to a patient who had a history of G2 trastuzumab deruxtecan-induced pneumonitis that is now resolved?
There are no prospective data to guide this decision; the decision requires careful individualization. TDM-1 (ado-trastuzumab emtansine has a substantially lower pneumonitis risk than trastuzumab deruxtecan (1.6-1.9% with TDM-1 compared to 9.6-10.5% with trastuzumab deruxtecan), and TDM-1 uses a dif...
Despite the paucity of strong data showing benefit of chemotherapy + radiotherapy in patients with stage I-II high risk histology endometrial cancer, if you recommend treatment with both modalities, how do you determine treatment schedule?
For the purpose of this answer, I'll define high risk as serous, carcinosarcoma, undifferentiated, and dedifferentiated. Clear cell carcinoma can be considered and likely treated more by its molecular profile. As you indicate, there is little data to support the routine use of chemotherapy for FIGO ...
Do you continue daratumumab beyond 24 months in first line treatment of amyloidosis?
This is an important and common clinical question, and one for which prospective data are currently limited. For background, the ANDROMEDA clinical trial (Kastritis et al., PMID 34192431) demonstrated that the addition of daratumumab to cyclophosphamide, bortezomib, and dexamethasone (CyBorD) signif...

Would you add immunotherapy to FOLFOX if the patient is not a FLOT candidate for neoadjuvant gastric cancer, extrapolating data from the MATTERHORN study?
While it is always somewhat perilous to extrapolate from a proper study to lesser situations, this seems quite reasonable. It seems highly unlikely that the removal of Taxotere from a fluoropyrimidine-oxaliplatin-based regimen would render immunotherapy less effective in gastric cancer. In the MATTE...
How do you counsel eligible patients on lung cancer screening who are hesitant because of the cancer risk from CT scans?
This is simple. The risk of lung cancer in patients who have smoked for >20 years is orders of magnitude higher than the theoretical risk of medical X-ray-induced cancers from low-dose CT (LDCT) screening. A typical LDCT scan exposes patients to approximately 1.5 mSv of radiation, equivalent to abou...
