Early Detection of Breast Cancer in Women With Suspicious Mammograms
Study Overview
Detailed Description
Breast cancer is a leading cause of cancer mortality in women worldwide. According to estimates, approximately 46,000 women in the United States, and 130,000 women in the European Union, die due to breast cancer yearly. Early detection is of paramount importance in reducing mortality from this major public health burden. Screening mammography has been shown to reduce breast cancer mortality by 20% to 35% in women aged 40 to 69 years. Detection of small volume breast cancer at early stages is associated with a 10-year disease-free survival rate as high as 98% in patients with pT1a,bN0M0 tumors (measuring 1 cm or less, with disease-free axillary lymph nodes and no distant metastasis). The assumption that early diagnosis will lead to improved treatment outcomes has driven the search for diagnostic biomarkers.
Despite this enthusiasm, a biomarker for stage I breast cancer has been elusive. The predictive value of mammography declines in cohorts of patients with denser breast tissue and smaller lesions, and recent studies have indicated that the small amount of biomarker molecules emanating from a breast tumor of less than 1 cm is well below the sensitivity of detection for current analytical methods. In addition, biomarkers in body fluids are highly perishable. Biomarkers break down during collection, transport and storage due to endogenous degradative enzymes yielding false negatives. Thus there is a significant need for new technologies that will a) identify and measure low abundance biomarkers (less than 1 nanogram/mL), and b) is low cost and can be seamlessly integrated into the clinical workflow.
Primary Objective:
The primary goal of this study is to a) experimentally discover putative plasma markers for detecting early, stage I breast cancer in the setting of a suspicious mammogram and distinguish those cancers from benign lesions b) verify the putative markers through molecular profiling; and c) validate the markers by mass spectrometry.
Secondary Objectives:
- Determine percent accuracy of breast cancer diagnosis in the context of 3D mammographically (screen detected) tumors.
- Determine percent precision of cancer diagnosis in the context of 3D mammographically (screen detected) tumors.
- Discover additional protein markers of early stage breast cancer that distinguish these tumors from benign lesions identified by mammography by comparing protein markers between patients with invasive cancer vs. benign tumors as determined by biopsy.
- Additionally compare protein markers between patients with invasive cancer and pre-invasive neoplasms as determined by biopsy.
- Bank samples for future research and sequencing.
