What are your top takeaways from SGO 2023?
There were many great presentations at SGO 2023 along with a few practice changing presentations. Two pivotal randomized phase III clinical trials enrolled advanced, metastatic endometrial cancer patients. Each demonstrated dramatic benefit with the addition of immunotherapy to chemotherapy (followe...
What small bowel dose constraints do you use in gyn brachytherapy?
There is no good outcome data available with this, although some dosimetric studies have limited 2 cc to 60-65 Gy (EQ2). That being said, it is important to monitor at each fraction the closest loop of small bowel and attempts should be made to avoid any hot spots and to spread out that dose to diff...
When do you use a brachytherapy vaginal cuff boost in postoperative cervical cancer treatment?
I limit use to close or positive margins, or if the patient has had an incidental simple hysterectomy done instead of a radical hysterectomy.
Is there a role for elective para-aortic nodal irradiation in endometrial cancer?
We treat in two scenarios:One is for patients who have had surgery done, have positive pelvic nodes on pathology, and PA nodes have not been dissected. For these patients, surgical series report a risk of pa nodal involvement of 40-50% and we treat pelvic and PA region after adjuvant chemotherapy.Th...
In a surgically staged Stage II Grade 1 endometrial adenocarcinoma, with no other high risk factors, would you treat with brachytherapy alone or add on the pelvic RT?
Yes, the current stage II was excluded from PORTEC 1 and 2 and were part of GOG 99 and GOG 249. With stromal invasion there is risk of nodal, vaginal, and parametrial (if only simple hysterectomy was done) recurrence, and for that reason we offer pelvic EBRT. That being said, if stromal invasion is ...
For a patient with vaginal adhesions/stenosis, do you recommend any other therapy besides a dilator?
Yes! In patients who have received radiation and have stenosis I frequently given topical estrogen cream with their dilators to help prevent or treat vaginal stenosis. My patents report that it helps with the pain associated with vaginal atrophy when they try to use their dilator. I treat a lot of c...
How would you manage a Stage IB endometrioid endometrial cancer, status post staging surgery, with a rapid vaginal recurrence <1 month post operatively?
A rapid recurrence like this is unusual, but we have definitely seen it. Cuff recurrences require multidisciplinary management. The most worrisome feature of this patient is the rapidity of recurrence. For the initial management, I would probably have recommended some kind of adjuvant treatment afte...
How would you manage a clinically inoperable, stage IIIB, MMR deficient uterine cancer?
Tough situation and uncommon case. If definitely inoperable, your options are to do preoperative systemic therapy or preoperative radiation therapy. I often advocate for preoperative radiation therapy as these tumors tend to respond well to radiation, and you can save the standard-of-care chemothera...
Would uterine serosal involvement change your adjuvant treatment recommendation for a patient with Stage II grade 2 endometrial cancer?
Would recommend chemotherapy and vaginal brachytherapy. Had the patient had Stage II, Grade 2 disease (ignore the ITC for a moment), we would offer the patient pelvic radiation therapy alone based on GOG 249 and PORTEC 3 results, the latter of which showed a benefit of chemotherapy largely driven by...
How would you approach treatment for a locally advanced cervical cancer in the context of a completely prolapsed uterus in a non-surgical candidate?
In the few cases I have done, it was reducible and would have it pushed in daily during the course of EBRT, and also made brachytherapy feasible. One which is not reducible is a challenge with both EBRT and brachytherapy. One can treat with chemo RT and hope regression of tumor would make brachyther...
