An observational study in Breast Cancer and Abnormal Mammogram, Unspecified, sponsored by Menssana Research, Inc.. Status unknown at 3 sites in 3 countries. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-02-16.
Sponsored by Menssana Research, Inc. · Observational
To validate a breath test that predicts risk of breast cancer and an abnormal mammogram.
We will determine the accuracy of volatile organic compounds (VOCs) in the breath as predictors of risk of breast cancer and an abnormal mammogram. Breath samples will be collected using an ultra-clean collection bag and analyzed with gas chromatography surface acoustic wave detection (GC SAW)
The study will be performed in two phases:
Phase 1: Model-building phase (cross-sectional study): Breath VOCs will be employed to construct multivariate algorithms that distinguish between normal women and those with breast cancer and abnormal screening mammograms.
Phase 2: Model-testing phase (cross-sectional study): The predictive accuracy of these algorithms will be tested to predict outcomes in normal women and those with breast cancer and abnormal screening mammograms.
12,544 studies on the registry are indexed under Breast Neoplasms; 2,892 are open to participants now.
This study's planned enrollment of 1,000 is above the median of 184 across 2,642 observational studies indexed under Breast Neoplasms.
