How are you deciding between T-DXd/pertuzumab and THP> HP/tucatinib in patients with metastatic HER2+ breast cancer?
I am reserving HP/tucatinib to the maintenance setting (after 1L THP, as was studied in HER2CLIMB-05, but also will plan to offer it as maintenance after 1L T-DXd/P in patients who experience cumulative toxicity on T-DXd/P and need to stop). I would tend to offer HP/tucatinib maintenance to those wi...
Which neoadjuvant/adjuvant chemotherapy regimen would you select in a patient with resectable stage IB pancreatic head adenocarcinoma and MDS-SF3B1 on luspatercept (baseline Hgb of 8-9 g/dL)?
Seems a bit unfair that the patient has both! First, I would consider resection upfront to ensure this key step rather than risk additional complications of chemotherapy. Perioperative or total neoadjuvant therapy is not standard for resectable disease yet (pending Alliance trial result). Second, bo...

What are the recommended prophylactic measures for managing or mitigating diarrhea when pertuzumab is combined with trastuzumab deruxtecan, given toxicity risk with each individually?
My understanding is that prophylactic anti-diarrheals were not required in the trial but left to institutional discretion. While the rate of diarrhea in DB-09 was 56%, most of these were Grade 1-2 (only 7% were Grade 3 or higher). As such, I am not starting antidiarrheals prophylactically, but I do ...
What is your preferred 1L treatment for newly diagnosed Del(17p)/TP53 mutation, high-risk CLL?
For patients with TN-CLL with TP53 aberration, the treatment options are usually based on patient factors. If a patient is a candidate for combination therapy, I prefer to treat them with uMRD-guided BTKi+BCL2i ± CD20 mAb. I only add a CD20 mAb to patients with no history of frequent infections and ...

Should we be stopping new starts of patients who can be triaged for 2-3 months like prostate cancers on ADT when significant community spread of COVID-19 is detectable in our area?
I would for those patients requiring ADT, which is the way I interpreted the question. I want to elaborate more because @Dr. First Last brought up other scenarios we should consider and he brings some more good points: Many patients could get active surveillance for a period of time before ADT is co...
How do you counsel patients and caregivers regarding management of cancer-associated cachexia?
ASCO guidelines re: anorexia/cachexia were just published in May 2020. Basically, they note the magnitude of the clinical problem and the limited therapeutic options proven to be helpful. They state that dietician consultation is reasonable to employ. They also note that it is reasonable for a clini...
What is your approach for endocrine therapy in young women (<35 years old) with HR+/HER2+ breast CA with residual disease after TCHP who will start adjuvant T-DM1?
She would be given the options of tamoxifen or ovarian suppression with an AI for five years and then a discussion at that time based on where the data goes in that time. Tamoxifen would have fewer side effects but less effective reduction of PFS per extrapolation from the SOFT/TEXT trials. Ovarian ...
How do you sequence Pluvicto vs docetaxel in a fit, chemotherapy-naïve patient with high-volume PSMA-avid mCRPC progressing on an ARPI?
I generally favor starting with docetaxel, though both are reasonable options. CCTG Study PR21 did not show a difference in radiographic progression-free survival between starting with docetaxel versus starting with Pluvicto in this setting. However, OS favored patients who started with docetaxel, a...
