GYNGHER - HER2 Expression in Gynecological Malignancies: a Brazilian Cohort
Brazil350 participantsStarted 2026-04-23
Plain-language summary
Adult patients with gynecologic cancer (endometrial, ovarian, cervical, vulvar and vaginal cancers) treated at Oncoclínicas \& CO sites will be enrolled for primary tumor immunohistochemistry (IHC) analysis. When sufficient paraffin tissue is available for biomarker testing, slides will be sent from partner Pathology Labs of the OC Precision Medicine network to Locus Lab (São Paulo) for HER2 staining with automated protocols (Dako HercepTest and Roche Ventana 4B5) and scoring using different criteria (gastric cancer, breast cancer, and endometrial cancer). Primary objective is to describe the prevalence of HER2 high expression (IHC 3+ using Dako HercepTest and gastric cancer scoring criteria) in endometrial, ovarian, and cervical cancers (common gynecological malignancies). Secondary objectives are to describe the prevalence of HER2 high expression (IHC 3+ using Dako HercepTest and gastric cancer scoring criteria) in vulvar and vaginal cancers (rare gynecological malignancies); and to describe the prevalence of different HER2 expression levels (IHC 0, 1+ and 2+ using Dako HercepTest and gastric cancer scoring criteria) across all gynecological malignancies, to describe HER2 expression levels as per endometrial cancer scoring criteria in the endometrial cohort; to describe the association of different histological subtypes of gynecological cancer with HER2 IHC expression levels.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age \>= 18 years at sample collection; - Diagnosis of cervical, endometrial, ovarian/peritoneum/uterine tube, vulvar, or vaginal cancers;
* Sufficient paraffin primary tumor tissue for biomarker testing in the OC Precision Medicine Pathology labs.
* Date of diagnosis of gynecological cancer must be from January 2020 to March 2025.
* Patients need to sign informed consent, or waiver of informed consent is granted.
Exclusion Criteria:
* Patients without sufficient paraffin tissue for the proposed biomarker testing.
* Patients whose diagnosis was performed in metastatic lesion.
* Patients with history of exposure to systemic anti-cancer therapies for the gynecological cancer diagnosis before surgery or excisional biopsy of gynecological cancer (information is available in the original histopathology request document stored in the LIMS).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
