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...
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...
Are there any alternative, hypofractionated RT courses for patients with DLBCL that can be used during the COVID-19 pandemic?
ILROG recently came out with guidelines pasted below: Synopsis of ILROG Recommendations for Administering Radiotherapy for Hematological Malignancies During Emergency Conditions of the COVID-19 Pandemic • We are facing an increased demand for RT to substitute or complement systemic therapy deemed i...
Would you use a hippocampal sparing technique when treating with PCI for a limited stage small cell lung cancer?
This is an important question where the evidence is evolving, and some key trials remain ongoing. Because the data remains in flux, in the ongoing phase 3 SWOG S1827/Maverick trial of MRI surveillance +/- prophylactic cranial irradiation (PCI) for LS and ES-SCLC, where I serve as the PI, hippocampal...
How has COVID-19 altered your recommendations for invasive mediastinal staging for NSCLC?
I just had this discussion with our chief of interventional pulmonolgy at MD Anderson. Some of his faculty are being asked to staff our COVID-19 patient floor. In addition, bronchoscopy procedures should be considered high-risk procedures, and are required to have at least 45 minutes in between proc...
In which group of patients you would send for RNAseq for translocations/fusions that might be missed by NGS in advanced NSCLC?
In patients who are never/rare smokers in whom tissue NGS is negative, I would strongly consider RNAseq of a recent or fresh biopsy. You can find the occult fusion (or missed MET) in about 15% of NGS negative, TMB low cases based on this recent very nice paper from MSKCChttps://www.ncbi.nlm.nih.gov/...
Can ctDNA be used to evaluate response to checkpoint inhibitors in NSCLC when pseudoprogression is suspected on CT imaging?
This is a scenario where ctDNA may have value in the future, as imaging alone is often not sufficient to reliably differentiate between pseudo-progression and true progression in patients receiving immune checkpoint inhibitors. A small study of 28 patients with melanoma suggested that ctDNA obtained...
Which patients would you treat with relugolix instead of injectable GnRH agonist therapy?
I would consider relugolix for patients with: 1. Intermediate-risk prostate cancer that needs a short course of androgen deprivation therapy 2. Patients with biochemical relapse that would benefit from a short course of ADT and salvage RT2.5 Patient with pre-existing cardiac comorbidities 3. Potenti...
