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...
Is it acceptable to treat patients with limited, asymptomatic brain metastases and EGFR-mutant NSCLC with upfront TKI?
Though some clinicians have been exploring the idea of targeted therapy for EGFR mutant brain metastases, this has been done in the absence of strong evidence. Reasons for pushing this idea are that sometimes the lesions seem to respond, and this has been seen in some single arm studies and anecdota...
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...
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...
When should you use single-fraction radiotherapy for spinal cord compression?
The SCORAD III trial is practice changing. But I do NOT plan to treat ALL patients with spinal cord compression with a single fraction of 8 Gy now. Here is why: SCORAD III is extremely important new study for the management of metastatic epidural spinal cord compression (MESCC) for patients with sho...
How does data from the HIMALAYA trial impact your first line treatment selection for advanced HCC?
The results from the HIMALAYA trial with the combination tremelimumab (CTLA-4 inhibitor) and durvalumab (PD-L1 inhibitor) reported an OS of 16.4 months compared to 13.8 months for sorafenib which was statistically significant (HR 0.78, p-value of 0.0035). With the limited data presented at ASCO GI 2...
Is there any role for ctDNA testing after surgery or SBRT for Stage IB NSCLC to determine the need for adjuvant chemotherapy?
This is another emerging use for ctDNA that has shown promising results in small studies. The TRACERx consortium in the UK looked at the evolution of early NSCLC over time in 100 patients who underwent resection. They performed multi-region sampling and whole-exome sequencing and created patient-spe...
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...
