BACKGROUND We studied the effect on tumour response to neoadjuvant therapy of the substitution of lapatinib for trastuzumab in combination with weekly paclitaxel after doxorubicin plus cyclophosphamide treatment, and of the addition of lapatinib and trastuzumab combined after doxorubicin plus cyclophosphamide treatment in patients with HER2-positive(More)
LBA506 Background: The purposes of this trial are to determine the effect of substituting lapatinib (L) for trastuzumab (T) in combination with weekly paclitaxel (WP) following AC as well as adding L to T with WP following AC on pathologic complete response (pCR) rates. METHODS Women with HER2-positive operable breast cancer received standard AC q3wks x 4(More)
Little is known about the cognitive factors associated with adherence to antiestrogen therapy. Our objective was to investigate the association between domain-specific cognitive function and adherence among women in a clinical prevention trial of oral antiestrogen therapies. We performed a secondary analysis of Co-STAR, an ancillary study of the STAR breast(More)
OBJECTIVES This study examined the relationship between positive and negative affect, depressive symptoms, and cognitive performance. METHODS The sample consisted of 1479 non-demented, postmenopausal women (mean age = 67 years) at increased risk of breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel Project's Study of Tamoxifen and(More)
BACKGROUND National Surgical Adjuvant Breast and Bowel Project (NSABP) trial B-31 suggested the efficacy of adjuvant trastuzumab, even in HER2-negative breast cancer. This finding prompted us to develop a predictive model for degree of benefit from trastuzumab using archived tumor blocks from B-31. METHODS Case subjects with tumor blocks were randomly(More)
Mammographic breast density is an established risk factor for breast cancer. However, results are inconclusive regarding its use in risk prediction models. The current study evaluated 13,409 postmenopausal participants in the NSABP Study of Tamoxifen and Raloxifene. A measure of breast density as reported on the entry mammogram report was extracted and(More)
BACKGROUND Uncertainties continue to exist concerning the outcomes and management of small (T1a/b N0 M0) invasive breast cancers. METHODS A central pathology review was performed of 638 such lesions from National Surgical Adjuvant Breast and Bowel Project (NSABP) clinical trial B-21. RESULTS Univariate analysis revealed a high risk for ipsilateral(More)
BACKGROUND The benefits of breast cancer adjuvant systemic treatments are generally assumed to be proportional (or constant) over time, but limited data suggest that some treatment effects may vary with time. We therefore systematically assessed the proportional hazards assumption across all 19 breast cancer adjuvant systemic therapy trials in the National(More)
OBJECTIVES The presentation of risks and benefits in clinical practice is common particularly in situations in which treatment recommendations involve trade-offs. The treatment of breast cancer risk with selective estrogen receptor modulators (SERMs) is such a decision. We investigated the influence of health care provider (HCP) counseling on women's(More)
