Do you get DEXA scans routinely before starting ADT for prostate cancer or endocrine therapy for breast cancer?
When initiating long-term ADT, I order a DEXA scan, check vitamin D level, ensure adequate dietary calcium intake, and discuss weight-bearing exercise/refer to PT when appropriate. I also continue check DEXAs every 2 years unless they otherwise meet criteria for a bone-modifying agent (mCRPC with bo...
How would you treat a young breast cancer patient with limited nodal involvement and an isolated sternal oligometastasis at diagnosis?
Although there is limited data to support this approach, I have treated similar patients with "curative intent" with respect to the RT portion of their treatment. If the sternal oligomet is in close proximity to the ipsilateral IMNs, it can be included within the partial wide tangent fields for the ...
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...
When should you use single-fraction radiotherapy for spinal cord compression?
The SCORAD III trial is practice changing. But I do NOT plan to treat ALL patients with spinal cord compression with a single fraction of 8 Gy now. Here is why: SCORAD III is extremely important new study for the management of metastatic epidural spinal cord compression (MESCC) for patients with sho...
How are you using predictive tests such as DCISionRT (PreludeDx) or OncotypeDX DCIS in the management of DCIS?
Advantages: It's a relatively cheap, simple assay to better individualize risk of DCIS. Not only prognostic like Oncotype DCIS but also predictive of the absolute benefit of radiation. Supposed to be a better risk assessment tool than traditional clinical pathologic factors. Can identify those who ...
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...
Would you recommend adjuvant radiation therapy to the locoregional lymph node basins for Merkel cell carcinoma (MCC) s/p WLE with negative margins and isolated tumor cells in 1 of 3 right inguinal sentinel lymph nodes?
Yes, this is not an easy disease to cure in the node-positive setting. So, the question can be framed: do isolated tumor cells constitute a benign finding, frank malignancy, or a space in between? I don't have an answer to that, and perhaps given the rarity of the entity, that answer will remain rec...
How do you talk to patients with intermediate-risk prostate cancer deciding between LDR brachytherapy (monotherapy) vs HDR mono vs SBRT vs EBRT, in terms of the comparative side effect profile of each approach?
It’s hard to add much to Dr. @Dr. First Last's excellent evidence-based answer, but I’ll elaborate on the counseling aspect from my perspective. Introduction: I start by acknowledging how difficult it is to weigh several totally foreign options and acknowledge the gravity of the decision. My patient...
How do you sequence radiation and capecitabine in breast cancer patients receiving adjuvant capecitabine for residual disease after neoadjuvant chemotherapy?
According to personal communication with Dr. Masakazu Toi (June 13, 2017), the corresponding author of the CREATE-X NEJM publication, radiotherapy was administered prior to capecitabine in the majority of cases on this study. It is worth noting that in CALGB 49907, a randomized trial comparing capec...
Is long term ADT now the standard of care with salvage prostate bed RT?
The dreaded hormone question...After 40 years of embarking on extremely well designed randomized trials, we still are confused about the who, what, when of ADT. Will RTOG 9601 create a new care standard? As @Dr. First Last said, I think we will see increased utilization. I have been using bicalutami...
