Methylation Profiling in Self-Samples for Identification of (Epi)Genetic Biomarkers for Gynecological Cancers (MYSSELF)

November 3, 2026 updated by: Wiebren Tjalma, Universiteit Antwerpen

The goal of the MYSSELF (Methylation Profiling in Self-Samples for Identification of (Epi)Genetic Biomarkers for Gynecological Cancers) study is to investigate which biological markers (i.e., (epi)genetic biomarkers) found in self-collected samples, such as first-void urine and vaginal samples, are linked to the presence of endometrial, ovarian, vulvar, or vaginal (pre-)cancer or to postmenopausal bleeding. Samples collected by clinicians from the cervix or vulva, as well as blood and tissue samples, will be used for comparison. The study will explore whether these markers could help improve earlier and less invasive detection of gynecological cancers in the future.

Detailed Description

Gynecological cancers include cancers of the cervix, endometrium, ovaries, vulva, and vagina. Early detection of these cancers is important, because treatment is more effective before the disease has advanced. At the moment, cervical cancer is the only gynecological cancer with a population-based screening program. For the other types (endometrial, ovarian, vulvar, and vaginal cancer), only diagnostic methods are available, but these are often uncomfortable for patients or not sufficiently specific. Hence, this study aims to improve early detection by looking for new biological markers (i.e., (epi)genetic biomarkers) in less-invasive samples that are associated with the presence of gynecological cancers. For this, different sample types are collected from patients with endometrial, ovarian, vulvar, or vaginal (pre-)cancer (n=100/(pre-)cancer) or from individuals with postmenopausal bleeding (n=330). These samples include self-samples collected at home (first-void urine (Colli-Pee 20 mL prefilled with urine conservation medium (UCM)) and vaginal self-sample (Evalyn brush)), clinician-collected cervical/vulvar samples, and blood samples. Only when a tissue sample is already being taken as part of the participant's standard treatment or diagnostic follow-up, it will be used for this study as well. As such, participants do not undergo additional invasive procedures as part of the study. All these samples are collected before any treatment begins (e.g., surgery, chemotherapy, radiotherapy…). For all analyses, current diagnostic results (e.g., dilation & curettage, transvaginal ultrasonography, blood biomarker CA-125, vulvoscopy, echography, imaging (CT, PET, MRI)) and cancer (histology) diagnoses will be used as the final diagnosis. A questionnaire will provide more information about the presence of risk factors and participants' experiences with the self-sampling methods.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Individuals having female genital organs, regardless of their gender identity.
  • 18 years old or older at the time of signing the informed consent form.
  • Diagnosed with either endometrial, ovarian, vulvar, or vaginal cancer irrespective of stage; diagnosed with one of their precursor lesions; or individuals with postmenopausal bleeding.
  • Has not started any form of cancer treatment prior to study enrolment.
  • Written informed consent must be obtained from each participant.

  • Participating in another interventional clinical study (where, e.g., a medical device, drug, or vaccine is evaluated) at the same time as participating in this study. Participation in another observational or low-interventional clinical study at the same time is allowed.
  • Unable to give informed consent.
  • Participants with a history or current evidence of any condition or abnormality that might confound the results of the study, or when it is not in the best interest of the participant to participate, in the opinion of the investigator.

Exclusion criteria related to blood withdrawal:

  • The participant has severe anemia.
  • The participant received a blood transfusion two weeks before sample collection.

Experimental: Participants Providing Samples for Biomarker Analysis

Participants will collect one first-void urine sample and one vaginal self-sample at home, the day before or the day of their planned consultation at the hospital or at the hospital itself. During the hospital visit, an additional clinician-collected cervical and/or vulvar sample and a blood sample will be collected for the study. If a tissue sample is already being taken as part of the participant's standard treatment or diagnostic follow-up, it will also be used for this study. Current diagnostic results (e.g., dilation & curettage, transvaginal ultrasonography, blood biomarker CA-125, vulvoscopy, echography, imaging (CT, PET, MRI)) and cancer (histology) diagnoses will be used as the final diagnosis.
Device: Colli-Pee 20 mL device with UCM

Participants will collect a first-void urine (the initial part of the urine stream) sample with the 20 mL Colli-Pee device prefilled with urine conservation medium (UCM, DNA Genotek, Canada). This sample can be taken at home the day before or the day of the planned consultation at the hospital or at the hospital itself.

Device: Evalyn Brush

Participants will collect a vaginal self-sample with the Evalyn Brush (Rovers Medical Devices, The Netherlands) at home the day before or the day of the planned consultation at the hospital or at the hospital itself.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number and overview of biomarkers associated with the presence of gynecological (pre-)cancers
Time Frame: 48 months

The primary objective of this study is to determine the feasibility of detecting (epi)genetic biomarkers in participants with (pre-)cancer (endometrial, ovarian, vulvar, or vaginal cancer). This evaluation will be conducted using multiple sample types: self-samples (first-void urine and vaginal samples), clinician-collected cervical/vulvar samples, blood samples, and tissue samples.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comparison of the biomarkers in different sample types
Time Frame: 48 months

The secondary objective is to compare the presence of biomarkers across different sample types (self-samples (first-void urine and vaginal samples), clinician-collected cervical/vulvar samples, blood samples, and tissue samples).
48 months
Association of biomarkers and presence of postmenopausal bleeding
Time Frame: 72 months

The third objective is to explore the association of the identified biomarkers with clinical characteristics in individuals with postmenopausal bleeding, a symptom that can arise from a variety of conditions, including but not limited to endometrial cancer.
