AIM OF DATABASE Danish Breast Cancer Cooperative Group (DBCG), with an associated database, was introduced as a nationwide multidisciplinary group in 1977 with the ultimate aim to improve the prognosis in breast cancer. Since then, the database has registered women diagnosed with primary invasive nonmetastatic breast cancer. The data reported from the(More)
It is unclear if depression or depressive symptoms have an effect on mortality in breast cancer patients. In this population-based, nationwide, retrospective cohort study in Denmark, depression was defined as affective or anxiety disorders that necessitated psychiatric hospital admission. All the affective and anxiety disorders were divided and categorized(More)
OBJECTIVES To evaluate the effect on breast cancer mortality during the first 10 years of the mammography service screening programme that was introduced in Copenhagen in 1991. DESIGN Cohort study. SETTING The mammography service screening programme in Copenhagen, Denmark. PARTICIPANTS All women ever invited to mammography screening in the first 10(More)
BACKGROUND On average, aromatase inhibitors are better than tamoxifen when used as initial or sequential therapy for postmenopausal women with endocrine-responsive early breast cancer. Because there may be contraindications to their use based on side-effects or cost, we investigated subgroups in which aromatase inhibitors may be more or less important. (More)
BACKGROUND Postmastectomy radiotherapy is associated with a lower locoregional recurrence rate and improved disease-free and overall survival when combined with chemotherapy in premenopausal high-risk breast-cancer patients. However, whether the same benefits apply also in postmenopausal women treated with adjuvant tamoxifen for similar high-risk cancer is(More)
The purpose of this study was to investigate the association between tumor tissue levels of total tissue inhibitor of metalloproteinases-1 (TIMP-1) and prognosis in patients with primary breast cancer and to analyze whether measurement of TIMP-1 in tumor extracts added prognostic information to that obtained from measurements of urokinase-type plasminogen(More)
Oestrogen receptor concentrations were measured in primary tumours of 291 postmenopausal breast cancer patients with high risk of recurrence. These patients were a subset of the 1650 patients participating in the Danish Breast Cancer Cooperative Group's trial of adjuvant treatment with tamoxifen (30 mg daily for one year). A cut-off point of 10 fmol/mg(More)
PURPOSE A number of prospective studies have shown that adjuvant CEF significantly improves disease-free and overall survival as compared to CMF in breast cancer patients. Our aim was to determine whether the benefit of epirubicin versus methotrexate differs according to TIMP-1 tumour cell immunoreactivity. EXPERIMENTAL DESIGN Tissue micro arrays from 647(More)
We have reported previously that both urokinase-type plasminogen activator (uPA) and its type 1 inhibitor (PAI-1) are statistically significant prognostic variables in patients with high-risk breast cancer (Grondahl-Hansen et al., Cancer Res., 53:2513-2521, 1993), and we recently described that the uPA receptor (uPAR) is a prognostic marker in(More)
The tumor level of TIMP-1 has been suggested as a new prognostic marker in breast cancer. The purpose of this study was to investigate whether TIMP-1 also carries prognostic information when measured in blood as this is a much more preferable material compared with tumor extracts. Using ELISA, TIMP-1 was measured in prospectively collected preoperative(More)
