Contrast Enhanced Spectral Mammography (CESM) Study (CONTEND)

February 24, 2022 updated by: Professor Fiona J Gilbert, Cambridge University Hospitals NHS Foundation Trust

An Assessment of the Impact of CONTrast ENhanceD Mammography (CESM) on Patient Management and Comparison With MRI (CONTEND Study)

The aim of this study is to determine if the addition of Contrast Enhanced Spectral Mammography (CESM) to standard diagnostic imaging, results in a decision regarding patient management - discharge, follow-up, surgery or treatment - being made sooner than it would if the patient had followed the standard course of investigations and review.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Women with suspicious breast lesions following mammography and ultrasound will be eligible for the study. Those who consent to participate will be randomised either to receive Contrast Enhanced Spectral Mammography (CESM) in addition to standard care or to receive standard care alone.

Women randomised to receive CESM will undergo the procedure either during the same visit or if necessary on another date within a week. Any additional suspicious lesions detected by CESM will be biopsied along with the original lesion either under ultrasound or x-ray guidance. Biopsy of suspicious lesions is standard care and not part of the research protocol. Those randomised to receive standard care will undergo ultrasound or x-ray guided biopsy of any suspicious lesion identified by ultrasound or mammography.

Results of all biopsies will be discussed at the next multidisciplinary (MDT) meeting where a treatment decision (conservation surgery, mastectomy or neoadjuvent therapy) will be made for those with confirmed disease. MRI will be performed on appropriate women in line with standard practice. Additional disease detected by MRI will be biopsied, either under ultrasound or MRI guidance, if this will influence patient management. The results from these cases will be discussed at the next MDT meeting.

For those women in either arm of the study with benign biopsy results standard care will be followed.

A proforma will be used to record patient pathway, biopsy results and MDT patient management decisions for each case.

For women who received both CESM and MRI, a retrospective review of these images will be made in order to compare diagnostic accuracy. Images from each imaging modality will be read by a different reader for each case. CESM images will be read without the knowledge of MRI results and vice versa. A proforma will be completed by readers to record findings.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 85 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Be willing and able to give written informed consent for participation in the study.
  • Have a lesion of suspicion 3, 4 or 5 following mammography and ultrasound.

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Undergo a CESM
Patients will undergo an experimental Contrast Enhanced Spectral Mammogram (CESM) in addition to standard diagnostic procedures
Diagnostic test: Contrast Enhanced Spectral Mammogram
Undergo a Contrast Enhanced Spectral Mammogram in additional to standard of care
No Intervention: Follow Standard care
Patient will follow standard care pathway.

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
Assessment of impact the addition of CESM has on patient management - does this lead to an earlier diagnosis / treatment plan
Time Frame: Retospective analysis at end of data collection period ( approximately I year)
The pathway of each participant through the diagnostic process will be reviewed at the end of the data collection period to assess whether the addition of CESM resulted in a definitive decision regarding treatment being made earlier than in the usual diagnostic route.
