Should hippocampal-avoidance WBRT be the default option for WBRT?
I think this is a difficult question to answer as a lot depends on the particulars. Here's a list of some of those issues: Radiosurgery is very easily administered & frequently free of toxicity. Systemic agents are showing improved efficacy in the brain. Surveillance MR imaging = lower incidence of ...
How do you manage neurocognitive decline associated with chemotherapy (i.e. chemo brain)?
I agree with @Dr. First Last's detailed response. Practically speaking, I would also add that it is important to listen and validate your patient's concerns and respond to their frustration and sense of loss. A diagnostic evaluation will not only help you and your patient discover or 'rule out' othe...
Would you use upfront atezo/bev in a patient with HCC and untreated hepatitis?
Yes. I would not have concerns. For HBV, I would start treatment before or simultaneously. Studies have varied by protocol about the HBV viral load being under 500 or 100 but it is not clear this matters. There have not been flairs reported. In regards to HCV, again, not an issue for me.
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...
For an non-operative patient with IB1 cervical cancer, would you recommend RT alone or concurrent chemoRT for definitive therapy?
I usually favor RT alone as local control and the outcome is excellent unless they have adenocarcinoma, a suspicious pelvic node, or multiple high risk features (high grade with LVSI on bx).
What are best practices for radiation oncology patient and staff precautions with the COVID-19 pandemic?
COVID Update 1/30/21 Wow, it's been almost a year. Here are some updates from our practices at University of Maryland. We have successfully treated both PUIs and COVID+ patients at all of our practices. We have yet to have a patient to staff (or staff to patient) transmission. We do not break patien...
In a patient with borderline resectable pancreatic adenocarcinoma s/p 10 cycles FOLFOX and aborted Whipple due to locally advanced disease, do you recommend dose escalation beyond 54 Gy?
Yes, there is no contraindication to giving an ablative dose after exploration. 54 Gray is a palliative dose, which has not improved overall survival based on the LAP07 trial. While it's fair to say that we do not know the definition of definitive or ablative in LAPC, we have published OS results ve...
What resources/ancillary staff do you utilize for school re-entry after cancer treatment to decrease anxiety, improve self-confidence, and support emotional functioning?
Facilitating school re-entry for children and adolescents undergoing cancer treatment is an important component of comprehensive care. Maintaining engagement in school can help preserve a sense of normalcy and mitigate feelings of isolation and loneliness. However, the transition back to school may ...
How long after achieving a CR would you consider stopping pembrolizumab in metastatic melanoma?
Based on Keynote 001 and more recently on Keynote 006, where we observed sustained remission in more than 90% of the patients who had stopped pembrolizumab for complete response, we usually consider stopping pembrolizumab in patients who have a confirmed complete response (this means that we have tw...
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...
