Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 100 years
  • Women only
  • Adult, Older adult

Study population: For the retrospective cohort: All women with STIC diagnosed between 2015 and start of the prospective study are identified. Data up until that time-point will be collected. At the end of the data collection follow-up will be updated on the women in the retrospective cohort. For the prospective cohort: All consecutive women with isolated STIC from participating centres are informed on the study and requested to participate.

Who may be able to join

  • Women
  • Bilateral salpingectomy (with or without oophorectomy)
  • A serous tubal intraepithelial carcinoma at histopathological review

Who cannot join

  • Invasive cancer at initial surgery or pathological examination (either macroscopic and/or microscopic)

About this study

To prospectively assess the incidence of peritoneal carcinomatosis for women with isolated STIC (serous tubal intraepithelial carcinoma). Moreover, to identify histopathological characteristics of STIC which are reproducible and associated to the risk of peritoneal carcinomatosis and to report the findings of additional diagnostics.

Read the detailed description

Women with a BRCA pathogenic variant (PV) undergo a risk-reducing salpingo-oophorectomy (RRSO) to reduce their ovarian cancer risk of 17-44%. A residual risk for peritoneal cancer (PC) persists, with most patients having extensive tumour spread throughout the abdomen. Despite surgery and chemotherapy, the five-year survival rate of PC is only 14-30%. Recently it became apparent that PC is frequently preceded by a preinvasive serous tubal intraepithelial cancer (STIC) at RRSO. The entity STIC is often found conjointly with ovarian cancer, but can also be present as an isolated condition, mostly in high risk women. If this STIC is found at RRSO, the risk for PC was found to be 27.5% (95% CI, 15.6-43.9) after ten years whilst this risk was <1% without STIC. The pathophysiological mechanism of this association is not yet known and it is unknown which women with STIC are most at risk. Moreover, the additional value of diagnostics and management is unknown as data is lacking.

Objective: To prospectively assess the PC incidence for women with isolated STIC, to identify histopathological characteristics of STIC which are reproducible and associated to the risk of PC, and to report the findings of additional diagnostics.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The risk for peritoneal carcinomatosis in women with isolated STIC

    Measured: 10 years

Secondary outcomes (3)
  1. Risk factors

    Risk for PC in relation to patient characteristics such as age at diagnosis and presence of a genetic pathogenic variant.

    Measured: 5-10 years

  2. Histopathological characteristics

    Identification of histopathological characteristics of STIC which are reproducible and associated to the risk of PC.

    Measured: 5-10 years

  3. Additional diagnostics

    To report findings at additional diagnostics (ie. imaging, staging surgery, CA125).

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of BRCA Mutation and Serous Tubal Intraepithelial Carcinoma, run by Radboud University Medical Center.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 1 May 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Miranda Steenbeek, MD PhD (0031615909405, miranda.steenbeek@radboudumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The risk for peritoneal carcinomatosis in women with isolated STIC (time frame: 10 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2024.
