Use of Hair to Diagnose Breast Cancer
Recruitment status was: Recruiting
Procedure: x-ray diffraction of human hair
|Study Design:||Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single Blind
Primary Purpose: Diagnostic
|Official Title:||A Prospective Blinded Study to Evaluate and Characterise an Assay for the Diagnosis of Breast Cancer Using Synchrotron-Derived X-Ray Diffraction of Hair Fibres.|
- The primary outcome is the determination of the accuracy (sensitivity and specificity) of the x-ray diffraction test for breast cancer using hair. Sensitivity is defined as the proportion of all positive Fermiscan tests that are true positives.
- The prevalence of a positive x-ray diffraction hair test and a negative mammogram, and of a negative hair test and a positive mammogram
|Study Start Date:||December 2006|
The test has the potential to improve the diagnostic (and consequently therapeutic) paradigm for breast cancer.
Women attending a radiology clinic in the Mater Hospital, Sydney, for a mammogram will be invited to participate in the study. A few hairs will be cut from their head or pubic region, put into a coded container and sent to the sponsor for analysis by synchrotron-x-ray diffraction. Although an imperfect standard for a variety of reasons, mammography is the standard screening assay, and confirmation of the pathology of the lesions found by mammography is carried out by biopsy. This will be the standard to which the hair test results will be compared. A negative mammogram will confirm a negative hair test, but a negative mammogram combined with a positive hair diffraction test will need a different approach. In the event of a positive hair test and a negative second read of the mammogram, the patient will be contacted by the referring practitioner. Patients in this category will be offered a breast MRI. A negative breast MRI under these circumstances will be classified as a true negative.
