Do you include pembrolizumab for metastatic/recurrent cervical cancer per KEYNOTE-826 regardless of PDL1 status?
PD-L1 expression is the biomarker currently approved for assessing potential responsiveness to immune checkpoint inhibitor (ICI) therapy in cervical and other malignancies. The search for better biomarkers is ongoing. With that caveat, KEYNOTE-826 was a randomized trial of chemotherapy +/- bevacizum...
Would you favor giving mirvetuximab before paclitaxel/bevacizumab?
Given some lag time for tests to be completed, I have personally started ordering folate testing early in a patient's care so that I have the information available for when we are making decisions like which regimen to move to. Prior to this when waiting for results, I would give treatments like tax...
How do you modify the management of an SLE patient with active systemic lupus for a gynecological cancer that normally requires pelvic radiation and brachytherapy?
I have not done any specific modification for SLE. I would treat with VMAT and IGRT with a 5 mm PTV margin and ensure EBRT and HDR meet ideal dose constraints for OARs.
How would you treat a small cell carcinoma with a 4 cm right Bartholin's gland primary and a single small right inguinal adenopathy?
It’s like limited-stage SCLC would be treated with cis plus etoposide and RT (60-66 Gy). Will favor no elective pelvic node RT if pure small cell carcinoma and no mixed component.
How would you treat a high intermediate risk stage IA grade 2 endometrial ca?
If it is Stage IA, Grade 2 without additional risk factors, we recommend observation. It is not considered high intermediate risk.If it is Stage IA, Grade 2 with additional risk factors such as LVI or age 60+, we recommend a referral to radiation oncology to discuss. Anecdotally, most patients will ...
What normal tissue constraints do you use, if any, in patients receiving vaginal cuff brachytherapy alone?
We optimize based on the PORTEC 2 and PORTEC 4 protocol recommendations. We use CT-simulation and 5mm optimization points. There are no normal tissue constraints when using this approach and 2D planning can be utilized. We do not insert, for example, bladder points. Many planning studies have demons...
Would you consider chemoradiation + chemotherapy as in PORTEC-3 regimen for p53 mutated stage IA endometrial cancer, though this trial did not include those with stage IA disease?
There are not sufficient data to recommend this regimen in patients with stage IA endometrioid endometrial cancer. In subset analysis of patients with grade 3 endometrioid cancer with + LVSI, there was no difference in recurrence free or overall survival (OS) with the addition of chemotherapy. For p...
When do you expect the 2023 FIGO staging for endometrial cancer to become adopted clinically in the US?
Agree with the previous comment. Current adjuvant RT for stage I and II are based on mainly histopathological classification (PORTEC-I/II). However, the recent publication of PORTEC-4a (Horeweg et al., PMID 37487144) for stage I/II showed molecular classification predicts response for stage I/II. Mo...
How should molecular studies, in particular the presence of POLE or p53 mutations, be incorporated into the decision to treat an "intermediate risk" endometrial cancer patient with adjuvant therapy after hysterectomy?
PORTEC, ESMO, and SGO guidelines support molecular characterization of endometrial cancer based on the TCGA/ProMisE classifications. p53 is a predictive biomarker for response and prognosis while POLE is prognostic. Based on the most recent SGO clinical practice statement, these can be used to escal...
Outside of a clinical trial, do you currently incorporate the TCGA molecular classification into management decisions for patients with endometrial cancer?
I currently do not use the TCGA or ProMisE classifications to inform adjuvant therapy after surgery. Although exciting, it is premature to use this classification until we have the results of PORTEC-4a. These results will help us to better risk stratify patients and guide adjuvant treatment. That be...
