When treating an intact whole breast with hypofractionated radiation, how do you approach boost dosing in the case of a close margin?
In the Plenary session of the 2012 San Antonio Breast Cancer Symposium, Dr. John Yarnold reviewed all of the updates of the UK START and Royal Marsden HFRT trials and discussed the fact that 40 Gy in 15 fractions had become the standard for the UK's National Institute for Health Care and Excellence ...
Would you radiate the thoracic duct for bilateral chylothorax in a hematologic malignancy with no discrete adenopathy?
We have done for adenopathy, which relieves obstruction and thus helps with drainage, but we don’t know how it would help in this situation.

Would you add immunotherapy to FOLFOX if the patient is not a FLOT candidate for neoadjuvant gastric cancer, extrapolating data from the MATTERHORN study?
While it is always somewhat perilous to extrapolate from a proper study to lesser situations, this seems quite reasonable. It seems highly unlikely that the removal of Taxotere from a fluoropyrimidine-oxaliplatin-based regimen would render immunotherapy less effective in gastric cancer. In the MATTE...
In which patients do you utilize a breast MRI as part of the initial workup for breast cancer?
I'm not a fan of routine MRI in the work-up for early-stage breast cancer, but I do agree with the fairly standard list of selective indications mentioned previously. I also obtain an MRI when there is a significant discrepancy between standard imaging and physical exam. Examples would be: One or a...
Do you check LDH levels for patients with CLL who are asymptomatic and on surveillance?
I personally include LDH as part of my routine chemistry panel monitoring of CLL in surveillance for several reasons. Often, patients with CLL can show up with new anemia; in such cases, the differential diagnosis is autoimmune hemolytic anemia versus disease progression. An elevated, new LDH level ...

What is the rationale for the recent change in the NCCN criteria for very high risk prostate cancer?
As the new Chair of NCCN's Prostate Cancer Guidelines, I am happy to answer this.The purpose of risk groups is not merely to be a prognostic divider, but to help guide treatment. Many systems have been developed that have greater prognostication than NCCN risk groups, such as STAR-CAP (which is supe...
How do you counsel a young man receiving EBRT as part of TNT for rectal cancer about risk of infertility?
I counsel male patients that, although the testes are outside the target dose volume, they will receive enough radiation that it could, at least temporarily, impair their ability to conceive. I offer to refer them for sperm banking prior to starting treatment.
Do you see a role for omidubicel upfront in severe aplastic anemia for patients without a matched donor?
We typically use cord blood products if there is no available family member donor or reasonably matched unrelated donor. The use of haploidentical family donors is very effective, less expensive, and allows supplementation with CD34+ stem cell boosts if counts are suboptimal DeZern et al., PMID 3234...
