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...
Has precision medicine changed how you consent patients for treatment?
The use of precision oncology technology and genetics has changed the ability to provide informed consent. In general, the riskier or less standard of care a therapeutic intervention might be, the greater the need for informed consent. In this way, precision oncology has pushed the envelope especial...
In light of GOG-252, are there any situations where IP chemotherapy would be preferable following debulking of advanced epithelial ovarian cancer?
In GOG-252, the control arm (arm 1) was the dose-dense Japanese GOG (JGOG) regimen, compared to two IP-based arms (arm 2, IP carboplatin, and arm 3, IP cisplatin). As stated in our OGR, interpretation of the negative results of this study is difficult for several reasons. All three arms in GOG-252 r...
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...
Should 3 years of adjuvant osimertinib be the standard of care for resected Stage IB-IIIA EGFRm NSCLC?
Since my initial response to this question, the ADAURA study has been fully published (NEJM 383:1711, 2020) and the FDA has approved osimertinib as adjuvant therapy for people with resected NSCLC harboring an EGFR sensitizing mutation. However, neither of these events has altered my opinion that des...
Does the presence of cribiform histology at biopsy in prostate cancer affect your management in an otherwise intermediate-risk prostate cancer?
There have been no trials on this specific question, so there is room for debate and more science (hoping our recent grant submission in this area gets funded...). Here is my current thinking. This is for generally healthy patients with long life expectancy (≥10 years, but especially if ≥15 years). ...
What neoadjuvant therapy would you choose for a post menopausal woman with ER negative, PR positive high grade node negative breast cancer?
Assuming that there is no reason to doubt the results of the hormone receptor testing, and her HER2 is negative, I would treat her the same way I would a triple-negative cancer—I would not bother to send Oncotype as it should be high with the negative ER, and I wouldn't believe it if it came back lo...
How would you approach a patient with HR+, HER2- metastatic breast cancer who is endocrine resistant, with bone marrow involvement and pancytopenia?
Symptomatic bone marrow involvement (bone marrow carcinomatosis) is extremely rare in metastatic breast cancer and carries very poor prognosis. It is often associated with microangiopathic hemolytic anemia and DIC. Anemia is the most common manifestation and WBC and platelet counts are often not tha...
How would you approach a stage 1 HR+/HER2- pre-menopausal patient <50 years old with Oncotype DX RS of 24?
All the prior comments are very reasonable. It is hard to completely exclude a small absolute benefit from chemotherapy in this group. The trial's subset analyses aren't designed to definitively answer whether ovarian suppression or direct action of the chemo led to the observed risk reduction in <5...
How would you treat a patient with metastatic NSCLC on pembrolizumab with a sustained complete response, now with 2 isolated small liver lesions?
I am unaware of any "level 1" evidence for this approach, much of our data is anecdotal, however there is certainly reasonable experience of treating "oligo-progressive" disease with local therapies. While there is more experience in adrenal and CNS metastatic disease, I would think that a local the...
