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...
Would you stop current immunosuppressive therapy or delay starting immunosuppressive therapy in a patient with aplastic anemia who has been infected with COVID-19?
Not much is known yet about this specific situation—but our growing experience here in New York City suggests it may be safe. We have had several post-BMT patients who were on immune suppression for GVHD become COVID positive who have not had significant problems. Also, we have now treated 8-10 pat...
For a patient with localized, high-risk prostate cancer (Gleason >8, staged with PSMA PET), is prostate SBRT a reasonable treatment choice, and if so, what duration of ADT would you utilize in this setting?
Yes, I offer SBRT as a reasonable option for high-risk prostate cancer. This is admittedly an extrapolation from PACE-B, which studied treatment of intermediate-risk cancer, but it seems justified in my view. Safety is well established. Efficacy is supported by PACE-B, with an asterisk coming from N...
Is the PROTEUS data enough to change your practice in the treatment of patients with high-risk localized or locally advanced prostate cancer?
The question asks if the results of PROTEUS would/should impact practice patterns...let us take a look: ADT is not recommended to be used with radical prostatectomy in prostate cancer by any guideline. Apalutamide or any ARPI are not recommended to be used with RP in prostate cancer in any guideline...
Would you prioritize TACE or systemic therapy in BCLC B multifocal HCC with tumor bulk higher than "up to 7?"
This is a challenging area where we need more definitive studies. With the info available, I do favor systemic therapy for such patients. Liver directed therapy is unlikely to lead to adequate control for such multifocal disease and the patient is likely to require multiple treatments to different a...
Is there anything you use for patients with anticipatory nausea who has failed Ativan and Zyprexa?
I know of no data, but I would consider hypnosis, mediation and mindfulness, cognitive behavioral therapy, acupuncture, and medical marijuana as possible options for anticipatory nausea refractory to lorezapam and Zyprexa. Hypnosis, mindfulness, and cognitive behavioral therapy are in a sense are re...
Would you continue tarlatamab in CNS-only progression of small cell cancer if there is no systemic disease?
I would absolutely continue tarlatamab in this scenario. While there is evidence of at least some activity of tarlatamab in the CNS (e.g., Zhang et al., PMID 40126456), the effect can be transient, suggesting that intra- and extracranial discrepancy is possible/probable. I would handle isolated, oli...
Should we consider radiation therapy for patients with N2 EGFRm NSCLC who will receive osimertinib, though RT was excluded on ADAURA?
For an EGFR-mutant N2 disease, we favor adjuvant chemotherapy (OS benefit) and/or adjuvant TKI based on ADAURA trial (DFS survival). The only prospective data regarding the use of adjuvant radiotherapy comes from a phase III trial, Lung Adjuvant Radiotherapy Trial (Lung-ART), where patients were ran...
When do you consider using protons for breast cancer?
I think there is a limited role for protons in breast cancer outside of prospective studies at this time.With respect to partial breast irradiation, while initial trials showed some higher skin toxicities, modern institutional series have shown much better outcomes. That being said, the total number...
When using T-DXd/pertuzumab regimen in frontline treatment of HER2+ metastatic breast cancer, are you adapting the regimen with induction and then de-escalation to maintenance?
Outside of a clinical trial, I do not routinely define a fixed induction-and-maintenance strategy when starting T-DXd with pertuzumab. Instead, I individualize treatment over time based on response, tolerability, and patient priorities. While many patients achieve deep and durable responses, cumulat...
