Trial summary

The main objective of this project is to demonstrate the feasibility of DLSCT to detect breast cancer in women with dense breasts. Patients with locoregional advanced primary breast cancer and heterogeneously (n = 7) or extremely dense breasts (n = 7) as determined by mammography will be included in this study.

About this study

Official title: Dual-layer Spectral Computerized Tomography for Breast Cancer Detection in Women With Dense Breasts: a Single Centre, Feasibility Study - The DECREAS Study

The main objective of this project is to demonstrate the feasibility of DLSCT to detect breast cancer in women with dense breasts.

Patients with locoregional advanced primary breast cancer and heterogeneously (n = 7) or extremely dense breasts (n = 7) as determined by mammography will be included in this study. These patients have an indication for a positron emission tomography computed tomography (PET-CT) scan to search for distant metastases. In this study the participants will undergo an additional contrast enhanced DLSCT scan to determine the feasibility of spectral CT to detect breast cancer in women with dense breasts.

Being tested
Dual-layer spectral computerized tomography (DLSCT)
Medical subject headings
Breast Neoplasms

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dual-layer spectral computerized tomography (DLSCT)Diagnostic test

    Contrast enhanced DLSCT scan using a 128-slice dual-layer detector (IQon Spectral CT, Philips Health Systems) will be performed. Patients will be placed in prone position during the DLSCT scan in order to improve the visualisation of breast tissue and comparability with MRI images. During the examination we will administer a nonionic low-osmolar iodinated contrast agent (Optiray©) in order to visualise tumor angiogenesis.

What is being measured

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

  1. Visual tumor conspicuity

    The conspicuity of tumors will be graded on a 4-point confidence scale

    Measured: On the same 1 day as the regular PET-CT scan was performed

  2. BI-RADS score

    BI-RADS score according to the ACR BI-RADS lexicon

    Measured: On the same 1 day as the regular PET-CT scan was performed

Secondary outcomes (2)
  1. Iodine enhancement

    Iodine enhancement will be measured in Hounsfield Units (HU).

    Measured: On the same 1 day as the regular PET-CT scan was performed

  2. Iodine content

    Iodine content will be measured mg/mL.

    Measured: On the same 1 day as the regular PET-CT scan was performed

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Neoplasms and Breast Density, run by Rijnstate Hospital at 1 site in Netherlands.

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 5 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 6 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Contact Carla M Meeuwis, MD,PhD (+31 26 378 8888, cmeeuwis@rijnstate.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual tumor conspicuity (time frame: On the same 1 day as the regular PET-CT scan was performed). The study lists 2 primary outcomes in all. 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 6 Jan 2022.
