What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at different preventive surgeries for women with gene mutations that raise their risk of ovarian cancer. Researchers want to see if removing the fallopian tubes first and delaying ovary removal works as well as standard surgery or close monitoring. About 480 women will be followed for 3 years to track cancer rates, side effects, and quality of life.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study targets Chinese women at moderate-to-high genetic risk for hereditary ovarian cancer (HOC). The population includes documented carriers of pathogenic or likely pathogenic (P/LP) germline mutations in high-risk susceptibility genes, primarily BRCA1 and BRCA2, as well as other HRR-related genes such as RAD51C, RAD51D, BRIP1, and PALB2. The population encompasses both premenopausal and postmenopausal women seeking individualized risk-management strategies.

Ages

18 years and older

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Gender: Female. Age: 18 years or older at the time of enrollment.Genetic Risk: Documented carriers of pathogenic or likely pathogenic germline mutations in high-risk ovarian cancer susceptibility genes (including BRCA1, BRCA2, RAD51C, RAD51D, BRIP1, PALB2). Data Availability: Willing to provide informed consent and allow access to clinical records, genetic testing reports, and follow-up data (bidirectional cohort). Psychosocial Status: Ability to complete quality of life and psychological assessment scales (e.g., GCS, SF-36, FSFI). Exclusion Criteria: * Prior Malignancy: History of ovarian, fallopian tube, or primary peritoneal cancer prior to the baseline intervention. Synchronous Malignancy: Diagnosis of any other advanced-stage malignancy. Inability to Follow-up: Significant psychological, social, or geographical factors that would prevent regular long-term follow-up (3 years). Previous Extensive Pelvic Surgery: History of extensive pelvic surgery that precludes the feasibility of laparoscopic prophylactic salpingectomy or oophorectomy.
