For atrial fibrillation patients with high risk of CVA who cannot tolerate full dose AC due to bleeding, do you consider low dose/extended dosing anticoagulation even if they do not meet age/GFR criteria for a dose reduction, if Watchman is not readily available as an option?
Most drugs, including anticoagulants, have a dose-response. Therefore, one could argue that even though DOACs were not studied at low doses, except in defined sub-groups such as the very elderly, using such a dose in other situations may have some benefit. The problem is that without data, we simply...
What are your top takeaways in Medical Oncology from SABCS 2025?
lidERA trial. This is the first phase III trial showing an advantage for an oral SERD giredestrant over standard endocrine adjuvant therapy in early breast cancer. Treatment with giredestrant led to a 30% reduction in the risk of invasive disease recurrence over standard endocrine therapy at the fir...
Under what circumstances would you start steroids for a patient with a new brain tumor prior to biopsy or resection?
In my opinion, for all brain tumors regardless of type, steroids should be initiated if it is felt that perilesional edema is the predominant cause of presenting symptoms or the amount of perilesional edema is large enough to cause midline or trans-tentorial shift, even if asymptomatic. Otherwise, f...
When would you continue atezolizumab/bevacizumab beyond progression in advanced HCC?
There are many effective drugs now in HCC. If there is true progression, I would change therapy. What is true progression? I think, a confirmed new lesion and/ or significant growth of the current disease. A few mm seen on a scan sometimes is read by radiology as PD but if the lesion is 8 mm, it's n...
For patients with early stage resected giant cell lung cancer and other less common histologies, are there any specific considerations for adjuvant therapy?
Giant cell carcinomas/pleomorphic carcinomas/sarcomatoid carcinomas are difficult, and typically aggressive entities. In reviewing the literature, there is precious little data to guide the selection of cytotoxic chemotherapy (most reports are pathology studies, some case reports, and unfortunately,...
What is your approach to systemic anticoagulation for patients with hypoalbuminemia and nephrotic syndrome secondary to a non-membranous nephropathy condition?
Patients with nephrotic syndrome (NS) and hypoalbuminemia have a several-fold higher risk of venous thromboembolism (VTE) than the general population and also a somewhat higher risk of arterial thromboembolism (ATE), such as MI and stroke. This risk seems to be higher in membranous nephropathy (MN) ...
Is there a role for resection of the cutaneous primary in a patient on dual-agent immunotherapy for metastatic melanoma?
Yes. The location and size (width, length) should be noted. The patient should first be treated with dual ICI. If the patient with metastatic melanoma, who has the primary intact, undergoes successful dual ICI therapy and has a documented CR, near CR, or excellent PR, which is typically noted within...
How would you approach adjuvant therapy for a premenopausal female with HR+, HER2+ breast cancer with N1mic disease?
Assuming that she has had breast surgery, the adjuvant chemotherapy that I would use in this is weekly paclitaxel at 80 mg/m2 x 12 weeks along weekly trastuzumab x 12 weeks followed every 3-week trastuzumab for a total duration of one year. This regimen with median follow-up of 6.5 years (Tolaney et...
How do you approach CNS prophylaxis in patients with DLBCL?
I think the NCCN-CNS-IPI based on the German data is a reasonable place to start when it comes to making decisions regarding CNS prophylaxis. We typically do IT MTX for patients on the lower end of the risk spectrum and high-dose IV MTX for patients on the higher end of the risk spectrum.
