""The NoTouch BreastScan (NTBS) is a non-invasive infrared imaging device which measures thermal gradients in breasts using dual infrared cameras and computer analysis. We evaluated NTBS as a predictor of breast cancer in patients undergoing minimally invasive biopsy. In this IRB-approved prospective trial, 121 female patients underwent NTBS prior to scheduled tissue biopsy. Twenty-two patients were excluded due to uninterpretable scans (n?=?18), diagnosis [http://www.selleckchem.com/products/z-vad-fmk.html find more] of a nonprimary breast malignancy (n?=?1), or no biopsy performed (n?=?3) for a total of 99 patients. Five patients had bilateral breast biopsies and one patient had two ipsilateral biopsies, resulting in 105 biopsies. Patients were prospectively scanned using a high specificity mode, termed NTBS1. All 99 patients were retrospectively re-evaluated in a high sensitivity mode, NTBS2. Of 105 biopsies performed in 99 women, 33 (31.4%) were malignant and 72 (68.6%) were benign. NTBS1 demonstrated a sensitivity of 45.5% and a specificity of 88.9%. Of 94 normal contralateral breasts, 9.6% had a positive NTBS1. In the retrospective evaluation, NTBS2 demonstrated a sensitivity of 78.8% and a specificity [http://en.wikipedia.org/wiki/RhoC RhoC] of 48.6%. Half (50%) of the normal contralateral breasts had a positive NTBS2. NTBS does not accurately predict malignancy in women with suspicious imaging abnormalities. The higher sensitivity mode results in an unacceptable number of false positives, precluding its use. Infrared imaging did not improve the sensitivity or specificity of mammography in this clinical setting. ""Abstract:? In oncology, quality of care is a major issue for patients and providers. Significant variations in care, including nonreceipt of adjuvant systemic therapy, nonadherence to therapy, and/or early discontinuation of therapy, occur frequently and may impact survival. Reasons for these variations [http://www.selleckchem.com/products/ly2157299.html learn more] are not well understood, but may play a role in the prominent disparity in breast cancer survival between blacks and whites. Since May 2006, the Breast Cancer Quality of Care Study (BQUAL) has recruited 1158 women with nonmetastatic breast cancer from several centers across the country, with completed data on 1057 participants to date. Detailed information on demographic, behavioral, biomedical, and emotional factors related to chemotherapy use was collected on each participant at baseline and at two follow-up interviews during the first 6?months. In addition, for women with ER+ tumors, further questionnaires were completed every 6?months regarding hormonal therapy use. Each participant was also asked to provide a DNA sample, and to allow medical record review. We surveyed physicians providing care to the study participants regarding attitudes toward adjuvant treatment. The mean age of participants was 58?years (SD 11.6), and 15% (n?=?160) were black. The majority had an annual household income
