About this study

Official title: Prospective National Multicentre Study to Validate a Model of Surgical Deescalation in Atypicals Breast Lesions

Routine screening mammography has increased the non-palpable suspicious lesion detection rate, requiring histopathological evaluation. The discovery of atypical lesions on the breast biopsy is associated with two interrelated risks:

  1. The risk of underestimating the severity of the lesion biopsied currently leads systematically to achieve a surgical resection for these patients while a breast cancer (BC) will finally identified at surgery in 10 to 25% of cases. Thus, unnecessary surgeries will be performed in 75 to 90% of cases (no cancer).
  2. These breast lesions confer long-term increase in the subsequent risk of breast cancer (cumulative incidence of 15 to 25% at 25 years). Thus, women identified with atypical lesions are then followed using clinical and mammographic annual evaluation.

The goal would be to get a model to assess the risk and no longer operate those patients at high risk of BC. Several groups have attempted to identify predictors of concurrent or secondary BC associated with the discovery of an unusual lesion at biopsy. However, they are often focused on a subtype of atypia (eg atypical metaplasia, atypical ductal hyperplasia, atypical lobular hyperplasia) and no prediction model has been validated in prospective multicenter. Based on a large retrospective study at Gustave Roussy, a prediction model (Nomat) has been developed, common to all atypical lesions, which can predict the presence of a BC at excision surgery (risk of concurrent BC). This model is based on the age of the patient, the disappearance of radiographic abnormalities (microcalcifications in general) after the biopsy and initial radiological lesion size. This model has good performance with an area under the curve (AUC) of 0.72. In previous series, with a BC high-risk threshold of 20%, negative predictive value was 90%, and this model would have prevented the surgery in 51% of patients (low risk patients by model). It is essential to validate this model by forward-looking and in different centers to ensure its relevance.

This is a multicenter prospective validation of the model on 300 patients operated for atypical lesions in 21 centers. All patients with atypical breast lesions have a routine surgery. The clinical data, imaging and histological data will be collected prospectively. The main objective of this study is to validate the model Nomat.

What is being measured

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

  1. Negative Predictive value of the NOMAT model

    The primary endpoint is the negative predictive value (NPV) of Nomat model used to predict the absence of breast cancer associated with cases of atypical lesions in breast biopsy

    Measured: Up to 3 months

Secondary outcomes (1)
  1. Exploratory research for biomarkers using DNA Seq

    The study will be Nomat parallel homogeneous database of prospective clinical and pathological data of patients operated for atypical breast lesions associated with tissue and blood samples (5 mL in EDTA tube).

    This bank will exploratory research of new biomarkers and validation of new biomarkers that may emerge in the coming years.

    Measured: Up to 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Biopsy and Blood sample in people with Breast Cancer, run by Gustave Roussy, Cancer Campus, Grand Paris at 1 site in France.

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 6 inclusion and 10 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: finished, as of the sponsor's last update on 24 Jul 2018. 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 France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Negative Predictive value of the NOMAT model (time frame: Up to 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02523612, which also lists 1 linked publication.

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 24 Jul 2018.
