When would you offer single fraction adjuvant partial breast irradiation instead of a 5-10 fraction course for early stage breast cancer?
We have not offered a single fraction, and our standard is 26 to 30 in 5 fractions. Data on a single fraction is not enough to support this recommendation for now.
How would you manage treatment of keloid that is so large it requests a graft?
16 Gy/4 fractions
Does postoperative radiation within 24 hours of a skin graft with a keloid resection increase the risk of graft failure?
The amount of radiation required to prevent keloid recurrence after excision is lower than what would be expected to compromise a skin graft. The studies cited are dealing with postoperative radiotherapy for cancer, where radiation doses are required to be higher than what is used for a keloid, and ...
Is there anything you use for patients with anticipatory nausea who has failed Ativan and Zyprexa?
I know of no data, but I would consider hypnosis, mediation and mindfulness, cognitive behavioral therapy, acupuncture, and medical marijuana as possible options for anticipatory nausea refractory to lorezapam and Zyprexa. Hypnosis, mindfulness, and cognitive behavioral therapy are in a sense are re...
Will patients who receive radiation to a large mediastinal nodal field have an increased susceptibility to COVID-19?
While the actual infection of COVID-19 has more to do with hygiene, social distancing, and prevention such as drugs or vaccines, the susceptibility for the patient to develop symptomatic progression of COVID-19, once infected, has a strong theoretical possibility. The factors that impact severe lymp...
How has COVID-19 altered your recommendations for invasive mediastinal staging for NSCLC?
I just had this discussion with our chief of interventional pulmonolgy at MD Anderson. Some of his faculty are being asked to staff our COVID-19 patient floor. In addition, bronchoscopy procedures should be considered high-risk procedures, and are required to have at least 45 minutes in between proc...
Would you consider offering salvage radiation to a patient with castrate resistant prostate cancer who has never had local therapy and has no evidence of lymph node or distant metastasis?
It's hard to give a great answer without knowing more information, such as the PSA, Gleason score, and T-stage at presentation, why he was treated with androgen deprivation alone up front, what AD he was treated with, how long he was under treatment before he became castrate resistant, and what is t...
Is there a role for selective arterial embolization of RCC before primary SBRT?
An interesting question! A good way to approach this question is with a list of potential advantages and a list of potential disadvantages. For the record, this is all hypothetical. I am not aware of any published literature that has explored this concept.Advantages: Significantly reduce the size of...
How does positive peritoneal washings factor into your treatment decisions regarding pelvic radiation and/or chemotherapy?
At this point, for patients who lack other adverse factors, we do not change management based on positive cytology for endometrioid histology.
In a patient with anorectal SCC, T2N0, with a history of bladder prolapse managed with pessary, would the pessary need to be removed prior to radiation?
I don't see a problem having a pessary in place at the time of each treatment, if the patient needs it in place in order to function. To reduce the risk of long-term vaginal stenosis, these patients should also have a vaginal spacer inserted at the time of each radiation treatment to better spare th...
