Carbohydrate antigens in nipple aspirate fluid predict the presence of atypia and cancer in women requiring diagnostic breast biopsy

<p>Abstract</p> <p>Background</p> <p>The goal of this prospective study was to determine (a) concentrations of the carbohydrate biomarkers Thomsen Friedenreich (TF) antigen and its precursor, Tn antigen, in nipple discharge (ND) collected from women requiring biopsy because of a suspicious breast lesion; and (b) if concentration levels predicted pathologic diagnosis.</p> <p>Methods</p> <p>Adult women requiring biopsy to exclude breast cancer were enrolled and ND obtained. The samples from 124 women were analyzed using an anti-TF and anti-Tn monoclonal antibodies in direct immunoassay.</p> <p>Results</p> <p>The highest median concentration in ND for TF and Tn was in women with ductal carcinoma <it>in situ </it>(DCIS). TF was higher in women with 1) cancer (DCIS or invasive) vs. either no cancer (atypia or benign pathology, p = .048), or benign pathology (p = .018); and 2) abnormal (atypia or cancer) versus benign pathology (p = .016); and was more predictive of atypia or cancer in post- compared to premenopausal women. Tn was not predictive of disease. High TF concentration and age were independent predictors of disease, correctly classifying either cancer or abnormal vs. benign pathology 83% of the time in postmenopausal women.</p> <p>Conclusions</p> <p>TF concentrations in ND were higher in women with precancer and cancer compared to women with benign disease, and TF was an independent predictor of breast atypia and cancer. TF may prove useful in early breast cancer detection.</p

A Cognitive-Behavioral Treatment for Depression in Rural American Indian Middle School Students

Rural American Indian (AI) middle school students with depressive symptoms who participated in a culturally modified version of the Adolescent Coping with Depression (CWD-A) course (n = 8) reported significant improvement in depressive symptoms at post-intervention and at 3-month follow-up. There was also a nonsignificant but clinically relevant decrease in participants\u27 anxiety symptoms. Students reported satisfaction with the intervention, and it was potentially more cost-effective and less stigmatizing than the individualized treatment-as-usual interventions to which it was compared. These results suggest the CWD-A is a promising approach for reducing depressive and anxiety symptoms in rural AI students and should be further evaluated with a larger sample of students
