Outcome

Type Measure Description Time frame Safety issue
Primary To assess the disease free survival (DFS) with 6 years of adjuvant anastrozole compared with 3 years of adjuvant anastrozole in postmenopausal hormone sensitive breast cancer patients, subsequent to 2 to 3 years of adjuvant tamoxifen After 9 years for the group with 6 years of adjuvant anastrozol, subsequent to 2 to 3 years of adjuvant tamoxifen or after 6 years for the group with 3 years of adjuvant anastrozole subsequent to 2 to 3 years of adjuvant tamoxifen
Secondary To compare the incidence of contralateral breast cancer after 6 years versus 3 years adjuvant anastrozole, subsequent to 2 to 3 years of tamoxifen After 9 years for the group with 6 years of adjuvant anastrozol, subsequent to 2 to 3 years of adjuvant tamoxifen or after 6 years for the group with 3 years of adjuvant anastrozole subsequent to 2 to 3 years of adjuvant tamoxifen
Secondary To compare the overall survival after 6 years versus 3 years adjuvant anastrozole, subsequent to 2 to 3 years of tamoxifen After 9 years for the group with 6 years of adjuvant anastrozol, subsequent to 2 to 3 years of adjuvant tamoxifen or after 6 years for the group with 3 years of adjuvant anastrozole subsequent to 2 to 3 years of adjuvant tamoxifen
Secondary To compare toxicity of 6 years versus 3 years of adjuvant anastrozole in postmenopausal hormone sensitive breast cancer patients, subsequent to 2 to 3 years of tamoxifen After 9 years for the group with 6 years of adjuvant anastrozol, subsequent to 2 to 3 years of adjuvant tamoxifen or after 6 years for the group with 3 years of adjuvant anastrozole subsequent to 2 to 3 years of adjuvant tamoxifen
Secondary To determine regional differences in the initial treatment of breast cancer retrospectively by collecting baseline information on initial therapies. Aspects of the initial treatment that will be investigated are e.g. the kind of surgery performed (breast saving or mastectomy) and whether or not chemotherapy is given and which chemotherapy was used in postmenopausal patients in relation to the primary tumour and patient characteristics. After 9 years
Secondary To compare the cost effectiveness of 3 years versus 6 years adjuvant anastrozole therapy, after subsequent 2 to 3 years of adjuvant tamoxifen treatment. After 9 years for the group with 6 years of adjuvant anastrozol, subsequent to 2 to 3 years of adjuvant tamoxifen or after 6 years for the group with 3 years of adjuvant anastrozole subsequent to 2 to 3 years of adjuvant tamoxifen
Secondary To assess patterns of care in The Netherlands in prevention, detection and treatment of osteoporosis in postmenopausal women with breast cancer treated with adjuvant anastrozole. After 9 years
Secondary To relate the number of osteoporotic fractures during and following treatment with adjuvant anastrozole with the compliance to osteoporotic guidelines. After 9 years
Secondary To analyse occurrence of distant (bone) metastases in relation to occurrence of osteopenia and osteoporosis, and in relation to use of supplements and therapy for reduced BMD. After 9 years
