Breast Study to Learn More About the Application of Optical Transillumination Measurements to Assess Breast Cancer Risk and to Potentially Detect the Presence of Breast Cancer. - Full Text View

Purpose

This study aims to evaluate if a light based technique, called Transillumination Breast Spectroscopy (TIBS), can be used to construct a non-invasive breast cancer risk predictor which provides a better odds ratio than mammographic parenchymal density.

Estimated Enrollment:	500
Study Start Date:	July 2006
Study Completion Date:	September 2009
Primary Completion Date:	March 2009 (Final data collection date for primary outcome measure)

Groups/Cohorts
1 Women with confirmed unilateral breast carcinoma or ductal carcinoma in situ (DCIS)
2 Women without radiological suspicious lesions, matched to cases by age (± 2.5 years), date of screening mammogram, and screening center.

Detailed Description:

In a previous cross sectional study in a group of women without breast cancer and with varying degrees of parenchymal density patterns, a strong association was demonstrated between Transillumination Breast Spectroscopy (TIBS) and x-ray derived mammographic density. From this, we expect that TIBS should also provide a comparable odds ratio (4-6) as mammographic density for breast cancer risk shown in other independent epidemiological studies. It is possible that TIBS may provide complementary information and a higher odds ratio if compared to the incidence of breast cancer. In contrast to mammography derived parenchymal density pattern, no historical TIBS data is available for a retrospective analysis and hence a cross sectional study within a group of screened women is proposed. We hypothesize that TIBS provides physical information about the breast tissue which can be used to construct a breast cancer risk predictor with an odd ratio > 6.
