How long of a delay are you willing to accept for vaginal cuff brachytherapy either as primary therapy or as boost?
The absolute benefit of vaginal cuff HDR boost is small and 6 months delay would negate any such benefit.
Given the results of PORTEC-4A, what adjuvant therapy, if any, would you offer a patient with a POLE-mutant endometrial cancer who also has a p53 mutation and substantial (>5 foci) of LVSI?
When you have dual mutation, the better of the two mutations drives the outcome, so it would be treated like a POLE-type. If substantial LVSI and pathological nodal assessment are done, I would favor Brachy alone. If nodes are not assessed, I would favor EBRT. The link below has references about dua...
Would you consider modifying T&O fractionation during the COVID-19 pandemic?
We have been using 7gy x 4 instead of 5 fraction regimen in the past. A 2 fraction regimen showed lower local control in comparison to 4 fractions in the IAEA randomized trial.
Between KEYNOTE A-18 and INTERLACE, for which patients would you recommend using one protocol over another?
We currently favor A-18 for stage III disease (clinical or node-positive). A-18 had a more modern RT technique both for EBRT and brachytherapy while in INTERLACE, 60% had a prescription to point A for brachytherapy. In comparison with the EMBRACE 3D brachytherapy series, pelvic recurrence rate seems...
How do you manage moist desquamation when treating vulvar cancer?
My experience is largely limited to the treatment of gynecologic malignancies, with the treatment of vulvar lesions the most common reason for development of moist desquamation. The first goal, in my opinion, is to prevent development of moist desquamation as much as possible. Skin folds that are no...
Do you believe the collective data support neoadjuvant chemotherapy or primary debulking surgery for patients with advanced ovarian cancer?
At this time, primary debulking surgery should be applied whenever feasible. However, I think we still do a poor job of selecting patients for PDS versus IDS. We neglect (or do not know) how tumor biology is really affected by surgery. For instance, BRCA-mutated tumors are likely easier to accomplis...
How do you manage a FIGO stage IB dedifferentiated endometrial carcinoma that is MMR deficient and p53 wt?
Aggressive disease. Favor chemo plus IO (MMR-d) (Van Gorp et al., PMID 39284383) followed by EBRT.
What is your strategy to help prevent paclitaxel-related neuropathy?
There are no proven strategies for prevention of CIPN and the use of these supplements is not recommended. Some supplements such as acetyl carnitine can actually worsen neuropathy outcomes and some supplements such as B12, vitamin C, and others may negatively interact with chemotherapy and worsen di...
When do you use a vaginal cuff boost with pelvic RT for stage II endometrial cancer?
Most prospective studies studying the role of external beam in endometrial cancer have treated patients with pelvic radiation (46/2 Gy or 50.4/1.8 Gy) without any brachytherapy. These studies have reported very low rates (2-3%) of in field failure in the radiation arms, so recommending external beam...
For vaginal cylinder HDR in the setting of adjuvant endometrial cancer radiation, do you routinely alter the prescription dose based on the diameter of the cylinder?
The prescription dose will remain the same regardless of the size of the cylinder that is used and should be specified to the vaginal surface (often 6 Gy x 5) or to 5 mm depth (often 7 Gy x 3). Because of the inverse square law, the dose to the non-prescription point will vary as a function of cylin...
