How will your management of head and neck cancers change with the COVID-19 pandemic?
Short answer: Most head and neck cancer radiation is as necessary as it gets. At this point, my management won't change very much. That may change as the pandemic evolves. Use all the appropriate precautions to stop the spread of COVID-19 and other viruses (we are using masks for every staff member,...
When will you prescribe 3 v. 6 months of FOLFOX or XELOX for the adjuvant treatment of colon cancer?
This set of studies will do more to reduce toxicity for patients than any other studies presented at ASCO this year. Based on these results, I plan on treating stage III patients as follows: 1. For T4 and/or N2 patients, I will continue to recommend FOLFOX or CAPOX for 6 months, and continue to adju...
What are the treatment options for a patient with unfavorable intermediate risk PCa who desires future child bearing?
The best option for such patients would be sperm banking prior to treatment, whether they undergo RT+ADT or surgery. See this prior post on this forum regarding the impact of RT on fertility. Given the expected internal scatter dose to the testes during a course of fractionated RT, it would not be s...
When do you consider certolizumab for pregnant women with antiphospholipid syndrome with positive lupus anticoagulant?
Certolizumab is a TNF-α antagonist with minimal or no transfer across the placenta. It was evaluated in the phase 2, open-label IMPACT (Improve Pregnancy in APS with Certolizumab Therapy) trial to prevent placenta-mediated adverse outcomes in pregnant patients with antiphospholipid antibody syndrome...
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...
What criteria would you consider to select patients for 20 Gy consolidative RT in DLBCL/HGBL?
The primary endpoint of the study was 5-year local control. The study was powered to estimate this endpoint after the last patient had at least 2 years of potential follow-up (which will be reported at ASTRO). Local failures after 2 years are uncommon. The estimated 5-year freedom from local recurre...
When making treatment decisions, how do you deal with conflicting results on HER2 measurement via IHC, FISH, and Oncotype Dx HER2 expression levels?
IHC and FISH are the standard-of-care assays for HER2 status determination, and treatment decisions should be based on IHC/FISH results rather than Oncotype DX HER2 mRNA expression levels when discordance exists (Tozbikian and Zynger, PMID 29498449; Neely et al., PMID 30230095). The Oncotype DX HER2...
Would you consider proceeding with a sentinel lymph node biopsy after wide excision revealed 1.2 mm residual non-ulcerated T2a melanoma on the upper back?
Any melanoma with Breslow’s depth of more than 0.8 mm (more than T1a) needs a sentinel lymph node biopsy for complete staging, due to higher chance of lymph node metastasis. Ideally, it should be done at the time of wide local excision, as doing the sentinel lymph node biopsy afterwards may be more ...
How should medical oncologists and dermatologists communicate about patients with at least Stage IIB/III cutaneous melanoma regarding neoadjuvant immunotherapy?
Only melanoma patients with stage III or resectable stage IV disease should be treated with standard-of-care neoadjuvant immunotherapy. These patients should see a medical oncologist first (and no longer last, as is the current process). I would recommend that the schedulers at your institution be e...
What whole brain radiation dose would you recommend for primary CNS lymphoma with partial response to HD-MTX-R and R-ICE and planned for concurrent ibrutinib?
There are many uncertainties in how to optimal treat patients with PCNSL. It is clear that high-dose MTX-based regimens should be pursued when feasible. The role, if any, of RT is controversial. If pursued, a WBRT-based approach is generally considered most appropriate.With that said, if a patient o...
