Are CHEK2 mutations a contraindication for breast conservation therapy with lumpectomy + RT?
Among women with early-stage breast cancer and moderate penetrance breast cancer susceptibility genes, such as CHEK2, decisions about breast surgery are largely based upon personal preferences. According to data from large population-based studies, women with CHEK2 pathogenic variants have about a 2...
How do you approach cisplatin dosing for locally advanced head and neck SCC in HPV-positive and HPV-negative patients?
Weekly cisplatin 40 mg/m² is not yet considered equivalent to high-dose cisplatin 100 mg/m² every three weeks, and high-dose cisplatin remains the preferred regimen for both HPV-positive and HPV-negative locally advanced head and neck squamous cell carcinoma. However, weekly cisplatin is an acceptab...
Do you refer all of your patients for EGD prior to initiation of atezolizumab/bevacizumab for advanced HCC?
Per the trial, this was required within 6 months of starting the study. However, in practice, I don't know that this strict rule would be necessary. For example, what if an EGD was done 10 months ago without varices? I don't think I would feel strongly about this. Similarly, if we could get one shor...
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...
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...
What is your strategy for ovarian suppression if unable to achieve goal estradiol levels with leuprolide 3.75mg monthly dose?
Monthly therapy rarely fails to induce adequate suppression. The choice of options will depend on whether the patient planned permanent or only temporary suppression AND the risk of recurrence of the cancer. If she will accept permanent suppression and has high risk disease, oopherectomy would be th...
Is there any role for early stem cell mobilization and collection during the SMM phase?
Prolonged exposure to lenalidomide can affect the ability to mobilize and collect stem cells, though this is less of an issue with increasing use of plerixafor (Giralt et al., 2009). If you are going to treat with an IMD, it is important to collect stem cells after 4-6 months of therapy, similar to ...
Would you use bevacizumab in a patient with advanced HCC and multiple large esophageal varices that have not been endosopically intervened upon?
Large varices should be treated endoscopically. I would avoid using Atezo/bev in a patient who has not had adequate treatment of their varices as there is a real risk of bleeding with bev in this setting.
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...
When do you suggest ovarian suppression for fertility preservation in premenopausal women receiving neo/adjuvant chemotherapy?
The benefit of ovarian suppression in young breast cancer patients should be looked into from two different aspects. First, the suppression of the ovary resulting in the hormone receptor-dependent cancer stem cell (minimal residual disease) suppression, and second, the preservation of the fertility ...
