研究概览
简要总结
The purpose of this study is to validate the interest of broadband spectroscopy analysis (femto/attosecond by infrared laser) on liquid biopsies in breast cancer screening.
详细描述
Each patient will have one or more liquid biopsy during the follow-up according to the cohort and have a mammogram at the same time.
Biopsies will be analysed by broadband spectroscopy in order to compare the results to mammogram result.

研究组 & 干预措施
Patient cohort
In this cohort, women for who an invasive breast cancer has been diagnose will be included.
Only one liquid biopsy will be collected before any treatment.
干预措施: liquid biopsy (Other)
Exploratory cohort
In this cohort, women with high risk of BRCA1/2 mutation but without invasive breast cancer.
6 liquid biopsies will be collected : each year after inclusion during 5 years.
干预措施: liquid biopsy (Other)
Control cohort
In this cohort, women recruited participated to organised breast cancer screening. They must not have an invasive breast cancer.
They will have 3 liquid biopsy : the first at inclusion and then at each mammogram every two years (organised breast cancer screening).
干预措施: liquid biopsy (Other)
结局指标
主要结局
Validation of the value of molecular profiling analysis in broadband laser spectroscopy on liquid biopsies for breast cancer screening
时间窗: Comparison between the different cohorts at (T0 : inclusion) and the others visits (T1:+1year; T2: +2years; T3 : +3years; T4:+4years; T5: 5years)
To validate the value of molecular profiling analysis in broadband laser spectroscopy on liquid biopsies for invasive breast cancer screening by comparing a cohort of patients with localized invasive breast cancer (Stage I/II) to a cohort of women without invasive breast cancer from organized or individual age-matched screening.
次要结局
- Correlating the results of high-speed laser spectroscopy analysis on liquid biopsies with mammography data (ACR 0-5)(T0: inclusion; T1:+1year; T2: +2years; T3 : +3years; T4:+4years; T5: 5years)
- Comparison of BRCA1/2 patients molecular profiles with control and patient cohorts derived from broadband laser spectroscopy(T0: inclusion; T1:+1year; T2: +2years; T3 : +3years; T4:+4years; T5: 5years)
- Estimate detection rate of both breast cancer screening methods (spectroscopy/mammography) for control cohort(T0 : inclusion; T2 : +2 years; T4: +4years)
- To study the role of confounding factors in the structure of molecular profiles derived from broadband laser spectroscopy(T0: inclusion; T1:+1year; T2: +2years; T3 : +3years; T4:+4years; T5: 5years)
