How would you approach a stage 1 HR+/HER2- pre-menopausal patient <50 years old with Oncotype DX RS of 24?
All the prior comments are very reasonable. It is hard to completely exclude a small absolute benefit from chemotherapy in this group. The trial's subset analyses aren't designed to definitively answer whether ovarian suppression or direct action of the chemo led to the observed risk reduction in <5...
Which adjuvant chemotherapy regimen would you recommend for a peri-menopausal woman with synchronous stage IA primary breast tumors, one that is ER+HER2+ and the second ER+HER2-?
I would treat the patient with paclitaxel 80mg/m2 x 12 weeks plus trastuzumab for a year (Tolaney et al., Clin Oncol 2019). The more difficult question is the optimal anti-estrogen therapy: tamoxifen (TAM), TAM + ovarian suppression (OS), or aromatase inhibitor (AI) + OS. This is because the SOFT an...
Given the results from the BILCAP trial presented at ASCO, would you change to or initiate therapy with capecitabine for patients with biliary tract cancer in the post-operative setting?
The BILCAP study represents the first data from a large, randomized, prospective, adequately-powered trial demonstrating a survival benefit for adjuvant therapy in this difficult-to-treat and relatively rare cancer.Given that capecitabine is relatively well tolerated, I would likely change from gemc...
For patients on commercial teclistamab who achieve a response, are there patient-specific or response-specific parameters that would prompt you to de-escalate therapy from once per week?
I think it’s safe to say we really lack good evidence to guide us. However, we must balance the risk of persistent immunosuppression with teclistamab and its efficacy. The only piece of data I am aware of in this regard comes from ASCO 2023 in an abstract by @Dr. First Last. In the MajesTEC-1 study,...
Following long-term efficacy and safety data from the beti-cel trials, how do you approach gene therapy for eligible patients with transfusion-dependent β-thalassemia?
The results with beti-cel are excellent. So are the results with exa-cel. These two gene therapies use different approaches to modifying hemoglobin production in erythroid stem cells. Beti-cel adds a modified hemoglobin that resembles fetal hemoglobin using viral-mediated transduction, whereas exa-c...

What is your current practice for obtaining mutation status for a patient with newly diagnosed ovarian cancer?
My current practice is to test all newly diagnosed epithelial ovarian cancer patients (includes fallopian tube and peritoneal) with both germline multigene and somatic multigene/NGS panels. Only recently have I adopted the practice of concurrent testing at diagnosis rather than basing the decision t...
When, if ever, would you recommend risk reducing BSO in patients with moderate penetrance breast cancer germline mutations?
RAD51C, RAD51D, and BRIP1 are all associated with significant risks of ovarian cancer and are appropriate for consideration of prophylactic oophorectomy, albeit perhaps at a slightly later age than BRCA1 and BRCA2. ATM and PALB2 may be associated with ovarian cancer risks that are similar to that of...
How do you stage patients with testicular cancer who may have CSIS disease?
This always looks easy, but you have to be careful and have patience. Some mistakes occur because providers use the PRE-orchiectomy markers or immediate post-orchiectomy markers before they have a chance to normalize. Also, providers sometimes react to low abnormal stable markers which often are fal...
Do you offer enasidenib with azacitadine in AML with an IDH2 mutation for patients ineligible for intensive induction chemotherapy?
I typically do not give enasidenib with azacitidine upfront for patients with AML with IDH2 mutation and ineligible for intensive induction chemotherapy. Based on the results of the VIALE-A study (DiNardo et al, NEJM 2020), I usually give venetoclax with azacitidine to those patients. In addition to...
