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...
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...
How would you approach adjuvant systemic therapy for an isolated, oligometastatic CNS recurrence of RCC that was treated with SBRT?
I tend not to treat patients with resected/irradiated CNS lesion(s) if there is no disease elsewhere. Such patients were not included in the adjuvant pembro study, the activity of any systemic therapy for CNS disease is not well-established, and in general, I worry single agent pembro is undertreatm...
In which situations do you offer ovarian suppression with chemotherapy to prevent the development of premature menopause in premenopausal women with ER negative breast cancer?
I would consider the use of GnRHa during chemotherapy in all women that are premenopausal at breast cancer diagnosis (irrespective of age) and that are concerned about developing the side effects of early menopause. Current evidence supports its use as a standard strategy for ovarian function preser...
Do you do prophylactic LP/IT chemotherapy in high risk APML prior to starting consolidation?
Extramedullary disease such as CNS involvement is quite uncommon at diagnosis in acute promyelocytic leukemia (APL). However, it can be seen in patients with relapsed disease. Both isolated CNS relapse and CNS relapse associated with morphologic or molecular relapse can occur. Yet one has the impres...

Does receipt of chemoimmunotherapy for LS-SCLC impact your recommendation for PCI?
Historic data showed that the addition of PCI for patients with limited-stage small cell lung cancer showing response after chemoradiotherapy improves overall survival and decreases brain failure rates by about 50%. Recently, the addition of consolidation immunotherapy after concurrent chemoradiothe...
Are there patients for whom CROSS followed by surgery and adjuvant nivolumab should still be considered, following data from MATTERHORN and ESOPEC?
ESOPEC does not invalidate CROSS—it redefines the preferred option for fit patients; in the real world, not every patient will be able to tolerate FLOT or d-FLOT: Yes. Despite the emergence of perioperative FLOT-based strategies from ESOPEC and MATTERHORN, CROSS, followed by surgery and adjuvant niv...
Given results of the RADICALS trials, is LT-ADT standard of care for salvage prostate RT?
I do not think long-term ADT is established as standard of care for salvage prostate radiation, as this would require a demonstration of improved overall survival in at least specific subgroups of patients. RADICALS-HD demonstrates improvement in freedom from metastasis as well as freedom from non-p...
How do you counsel patients on the efficacy of breast cancer risk reduction strategies such as breast MRI surveillance or bilateral mastectomy for those considered high risk by polygenic risk score, pathogenic variants, and/or family history?
This is a difficult question with limited data to guide decisions. The ultimate goal of any screening effort is to identify disease earlier so that treatment is more effective (and hopefully less onerous) so that fewer patients die. We have good data that enhanced screening in high risk populations,...
