BACKGROUND Tamoxifen has been the standard adjuvant treatment for postmenopausal women with hormone-responsive early breast cancer for more than 20 years. However, the third-generation aromatase inhibitor anastrozole has proven efficacy and tolerability benefits compared with tamoxifen when used as initial adjuvant therapy. We investigate whether women who(More)
Neoadjuvant (primary systemic) treatment is the standard treatment for locally advanced breast cancer and a standard option for primary operable disease. Because of new treatments and new understandings of breast cancer, however, recommendations published in 2003 regarding neoadjuvant treatment for operable disease required updating. Therefore, a second(More)
PURPOSE Cross-talk between the estrogen receptor (ER) and the phosphoinositide-3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathways is a mechanism of resistance to endocrine therapy, and blockade of both pathways enhances antitumor activity in preclinical models. This study explored whether sensitivity to letrozole was enhanced with the oral(More)
BACKGROUND Capecitabine is a rationally designed oral, tumor-activated fluoropyrimidine carbamate with high activity in metastatic breast cancer. This multicenter phase II study was designed to evaluate further the efficacy and safety of capecitabine in patients with metastatic breast cancer previously treated with a taxane-containing regimen. PATIENTS(More)
Bisphosphonates (BP) prevent, reduce, and delay cancer-related skeletal complications in patients, and have substantially decreased the prevalence of such events since their introduction. Today, a broad range of BP with differences in potency, efficacy, dosing, and administration as well as approved indications is available. In addition, results of clinical(More)
To establish the importance of CHEK2 mutations for familial breast cancer incidence in the German population, we have screened all 14 of the coding exons in 516 families negative for mutations in both the BRCA1 and BRCA2 genes. We found 12 distinct variants in 30 unrelated patients (5.81%), including 5 that are novel and an additional 4 found for the first(More)
PURPOSE Current adjuvant therapies have improved survival for premenopausal patients with breast cancer but may have short-term toxic effects and long-term effects associated with premature menopause. PATIENTS AND METHODS The Zoladex Early Breast Cancer Research Association study assessed the efficacy and tolerability of goserelin (3.6 mg every 28 days(More)
PURPOSE In postmenopausal women with estrogen receptor-positive early breast cancer, surgery is usually followed by a 5-year course of tamoxifen. This report presents results of a prospective, open-label, randomized study, designed to evaluate the benefits of switching to anastrozole after 2 years of tamoxifen treatment, compared with continuing on(More)
BACKGROUND For more than 20 years, tamoxifen has been the mainstay of adjuvant endocrine therapy for women with hormone-sensitive early-stage breast cancer. However, not only does tamoxifen have potential side-effects such as an increased risk of endometrial cancer and thromboembolic events, but patients can also develop resistance to the drug. We aimed to(More)
Mutation analysis of complex genes without hotspots for sequence variations, such as BRCA1, is time-consuming and expensive. Of all currently available methods, direct sequencing has the highest sensitivity, but also the highest costs. Other techniques, such as SSCP, DGGE, and PTT, are more economical but, depending on the experience of the investigator,(More)
