What is your recommended management for a pT1N0 perianal moderately differentiated SCC s/p wide local excision with close 1 mm deep margin?
It’s important to examine the patient before proceeding. Anal and peri-anal cancer can be multi-centric. I have had cases with pathology reports like this who had other areas of clearly invasive disease remaining. Assuming staging studies are negative and the physical examination reveals only a hea...
How does the performance of a LYMPHA procedure affect the timing and planning of post-mastectomy radiation?
This is increasingly being seen for patients undergoing ALND with LYMPHA or LVB procedures. They often have their arm wrapped for several weeks post-op. I will try to simulate 4-6 weeks postop; prior to sim, my nurse will reach out and if the arm is still wrapped or limited ability to lift the arm, ...
Do you ever consider hypo-fractionated palliative radiation postoperatively for bone metastases?
Yes, we use it routinely. We consider it one of the wise choices.
For a stable AVM after SRS, would you consider repeat SRS?
Yes. 3 years.
Would you deliver post-operative axillary radiation for breast cancer patients who have contralateral axillary disease s/p ALND?
For recurrent disease involving contra lateral axilla, I have treated undissected axilla and supraclavicular region only (not contralateral breast or chest wall).
How can oncologists be more collaborative with palliative care physicians?
First and foremost, for oncologists to be collaborative with palliative care physicians, a trusting relationship is a must (good communication amongst teams is key to optimal patient care). This is akin to PCP-Oncologist (or even PCP-any other specialist relationship). Before advances in science and...
When would you offer radiation for poorly differentiated thyroid cancer?
PD thyroid cancers are rare, of follicular origin, often iodine unresponsive, and can be addressed with surgery and postop RT. More advanced disease presentation is a much larger issue and DM rates are as high as 60% with poor response to systemic therapy to date. Unlike anaplastic thyroid cancers t...
How does depth of invasion factor into your decision making when considering postoperative radiotherapy for vulvar cancer?
I would not offer adjuvant RT for depth of invasion as only risk factor.
How do you manage post radiation chronic vaginitis with bleeding?
Limit trauma to the area. No biopsies unless absolutely necessary. Can use vaginal packs on a short term basis (don't leave in too long). Transfusions if indicated. Can try a course of metronidazole, which can treat an anaerobic infection, but also is purported to have oxygen-mimetic properties. Thi...
How do you counsel patients who want breast augmentation following breast conserving surgery and whole breast radiation?
I usually start by trying to better understand why they want to do this. I try to reinforce that the majority of patients have good to excellent cosmetic results (by both the patient and provider assessments). I emphasize that there will be continued anatomic changes in the breast post-RT (likely fr...
