The consequences of HMB are substantial and multifaceted, and, as we f...

The starting point for consideration of adjuvant chemotherapy is to quantify the risk of a distant recurrence. For estrogen receptor positive, HER2 negative breast cancer, Oncotype Dx RS data are critical for understanding the risk of a distant recurrence1 as well as endocrine and chemotherapy respo...

A total of one year for trastuzumab, including the part with chemotherapy, adjuvant or neoadjuvant. The benefit from addition of pertuzumab, as might have been predicted, was very small, since it is very hard to add any sizable benefit to trastuzumab without some logical risk stratification; for ER ...

Low-molecular-weight heparin demonstrates the greatest benefit in patients with cancer-associated pulmonary embolism, intermediate-risk PE, and those requiring outpatient management.

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 ...

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 ...

Since the NATALEE trial excluded patients who received more than 12 months of neoadjuvant or adjuvant endocrine therapy, I would probably not consider ribociclib for your patient, as she is too far out from initiation of endocrine therapy.

At this point, there are no prospective trials comparing checkpoint monotherapy and chemo-immunotherapy for patients with PD-L1 high NSCLC. The ongoing prospective INSIGNA trial will answer this question. If one does a cross trial comparison of pembrolizumab for patients with PD-L1 of >50% and chemo...

There is no clinical trial to provide a direct comparison between the two regimens, hence the answer to this question is usually driven by personal interpretation of the data and patient preference. The data for both regimens show a statistically significant PFS benefit and a superior response rate ...
