Is your approach to managing immune related adverse events altered at all in light of COVID-19?
First of all, I wish to thank @Dr. First Last from Johns Hopkins/Sibley for his advice addressing this critical topic.We are all witnessing a rapidly evolving crisis that none of us have been prepared for and it is the right thing to quickly consider as best as we can how the COVID-19 pandemic shoul...
Which adjuvant chemotherapy regimen would you recommend for a peri-menopausal woman with synchronous stage IA primary breast tumors, one that is ER+HER2+ and the second ER+HER2-?
I would treat the patient with paclitaxel 80mg/m2 x 12 weeks plus trastuzumab for a year (Tolaney et al., Clin Oncol 2019). The more difficult question is the optimal anti-estrogen therapy: tamoxifen (TAM), TAM + ovarian suppression (OS), or aromatase inhibitor (AI) + OS. This is because the SOFT an...
Should 3 years of adjuvant osimertinib be the standard of care for resected Stage IB-IIIA EGFRm NSCLC?
Since my initial response to this question, the ADAURA study has been fully published (NEJM 383:1711, 2020) and the FDA has approved osimertinib as adjuvant therapy for people with resected NSCLC harboring an EGFR sensitizing mutation. However, neither of these events has altered my opinion that des...
What is your preferred first-line therapy for transfusion-dependent beta-thalassemia?
Transfusion is my preferred first-line therapy (and standard of care) for beta-thalassemia major. For beta-thalassemia intermedia that has evolved into TDT, my preferred first-line treatment is mitapivat over luspatercept, particularly if the patient has extramedullary masses (that have been noted t...
How are you using liquid biopsy in the routine management of your patients with metastatic NSCLC?
The dramatic improvement in the prognosis of metastatic NSCLC patients harboring targetable oncogenic genetic alterations with highly effective therapy has underscored the need for tumor molecular profiling. There have been numerous studies in the past decade assessing the performance of ctDNA (here...
Is there a role for DDR gene mutation or tumor mutation burden/load in predicting response to immunotherapy in urothelial cancer?
Our recent work showed that urothelial cancers harbor high rate of alterations in DDR (DNA damage repair and response) genes, with 25 – 29% rate of deleterious alterations and up to 25% with variants of unknown significance – considering the genomic complexity of urothelial cancers, it is not un...
What is the longest acceptable interval between radical orchiectomy and adjuvant BEP for Stage IIB/III pure seminoma in the age of COVID-19?
Drs. @Dr. First Last and @Dr. First Last have worked with GCT experts to create practical recommendations during this pandemic. You can read these here. Briefly, these patients should be still be treated with timely curative intent. Treatment decisions will need to be individualized for each patient...
Is there any consensus or guidance on how to manage germ cell tumor patients in the COVID-19 era?
Germ Cell Tumor Management in face of SARS-CoV-2: Safe, Rational Modifications to Standard GCT Practice to Protect Public Health, GCT Outcomes, GCT Patients, and Health Systems. This bulletin has been produced by a concerned group of international experts in germ cell tumors, has not undergone exten...
When do you recommend patients get vaccinations with respect to their RT course?
I agree with @Dr. First Last's reply, and find that some patients are under the impression they are immunocompromised during radiation therapy and thus should avoid vaccines, when in fact the opposite is true. The skepticism behind the science of vaccination also can lead to avoidance, and so I try ...
Would weak PR positivity make you consider adjuvant endocrine therapy for a young pre-menopausal woman with a HER2 positive, ER negative breast cancer?
I would discuss the uncertainties, and would offer tamoxifen at the most (I would not subject the patient to the toxicities of OFS and AI). I would also have a low threshold to discontinue tamoxifen if there are toxicities. If there are minimal to no side effects, it may be worthwhile getting the th...
