Under what circumstances would you pursue completion ALND in a patient with multiple positive sentinel nodes after breast-conserving surgery?
For clinical/imaging node-negative disease with 1-2 positive nodes, now there are 7 plus clinical studies (ACOSOG Z0011, AMAROS, OTOASOR, SENOMAC, IBCSG 23-01, AATRM, SINODAR-ONE) which have shown no difference in axillary recurrence, DFS with dissection, but higher lymphedema as expected. The most ...
How do you incorporate Oncotype or Mammaprint recurrence score when planning an adjuvant CDK4/6 inhibitor for high-risk early-stage HR+ breast cancer?
Oncotype DX and MammaPrint recurrence scores are not used to guide adjuvant cyclin-dependent kinase 4/6 (CDK4/6) inhibitor therapy in high-risk, early-stage, hormone receptor-positive breast cancer. However, they were used to further identify the node-negative patient population with T2 or greater t...
What factors do you use to decide between ribociclib and abemaciclib for high risk HR+/HER2− early breast cancer?
For women who are eligible for both, we discuss both, but I am biased towards ribociclib for certain. The QOL issues we have had with abemaciclib in the adjuvant setting have been outrageous. Despite best supportive care and dose adjustments, I have women severely limiting their daily activities aro...
How would you manage a CVST secondary to a traumatic brain injury with the presence of intracranial hemorrhage?
When dealing with CVST after TBI, the mechanism of injury is not the same as a spontaneous CVST. There is often direct injury to the vein or the area overlying it. Given that these patients often have other traumatic injuries, and given the lack of clear evidence to support one therapy or another, I...
When, if ever, will you utilize T-DM1 in metastatic HER2+ breast cancer given trastuzumab deruxtecan's significantly improved efficacy vs T-DM1?
We now have very compelling data that trastuzumab deruxtecan (T-DXd) is highly effective in the second line setting and superior to T-DM1. The announcement of results came with the statement that "this study will lead to a paradigm shift in the treatment of Her2-positive metastatic breast cancer". S...
In elderly patients with advanced melanoma and idiopathic pulmonary fibrosis receiving active antifibrotic therapy, would neoadjuvant or adjuvant immune checkpoint inhibition be preferred?
I'd be very careful with the use of immunotherapy in an elderly patient with any sort of autoimmune disease, especially when receiving disease-modifying therapy. Having said that, there is no such contraindication to giving immunotherapy in such patients. Neoadjuvant setting: It is always preferred ...
How do you reconcile the differing results of the C-POST and KEYNOTE-630 trials when discussing treatment options with high-risk CSCC patients?
I explain that the two trials enrolled different risk populations, which likely accounts for the apparent discrepancy in outcomes — but when you look closely, they actually lead to the same clinical conclusion. C-POST deliberately enriched for very-high-risk patients (using well-established adverse ...
What are your top takeaways in GI Cancers from ESMO 2025?
1. MATTERHORN StudyThe global phase III MATTERHORN trial enrolled 474 patients with resectable gastric or gastroesophageal junction adenocarcinoma, randomized to receive FLOT alone or FLOT plus durvalumab. The primary endpoint, event-free survival (EFS), was previously reported as positive. Adding d...
How would you treat a patient with Gleason 8 or 9 prostate cancer, pretreatment PSA 15-24, with retroperitoneal adenopathy?
I would offer a similar approach to that described nicely by @Dr. First Last and @Dr. First Last: definitive RT+ADT+abiraterone, with SIB to the grossly positive nodes. My caveats and additions are: I start with a frank discussion with the patient re: evidence for various scenarios and general prog...
Would patients receiving targeted therapies be eligible for TTFields for brain metastases?
It is unknown whether NSCLC brain patients receiving targeted therapies should also receive TTFields. The most common patients would be those harboring EGFR mutations or ALK rearrangement. This would need to be studied and should not be presumed to be safe, as other unforeseen toxicities have occurr...
