BACKGROUND Trastuzumab--a humanised monoclonal antibody against HER2--has been shown to improve disease-free survival after chemotherapy in women with HER2-positive early breast cancer. We investigated the drug's effect on overall survival after a median follow-up of 2 years in the Herceptin Adjuvant (HERA) study. METHODS HERA is an international(More)
PURPOSE We sought to identify gene expression markers that predict the likelihood of chemotherapy response. We also tested whether chemotherapy response is correlated with the 21-gene Recurrence Score assay that quantifies recurrence risk. METHODS Patients with locally advanced breast cancer received neoadjuvant paclitaxel and doxorubicin. RNA was(More)
BACKGROUND Although axillary surgery is still considered to be a fundamental part of the management of early breast cancer, it may no longer be necessary either as treatment or as a guide to adjuvant treatment. The authors conducted a single-center randomized trial (INT09/98) to determine the impact of avoiding axillary surgery in patients with T1N0 breast(More)
PURPOSE Tremelimumab is a fully human monoclonal antibody specific for CTL-associated antigen 4 (CTLA4) with single-agent activity in certain tumors but has not been evaluated in patients with breast cancer. EXPERIMENTAL DESIGN In a phase 1 study, 26 patients with advanced, hormone-responsive breast cancer received tremelimumab (3-10 mg/kg) every 28 days(More)
Trastuzumab has an established role for the treatment of HER2-positive early-stage breast cancer because of the success of this agent in the adjuvant setting. Several key questions about the value of trastuzumab for the treatment of breast cancer, however, still need to be answered. Various differences in patient characteristics and treatment regimens were(More)
Two phase I, open-label trials in healthy subjects assessed whether co-administration with CYP3A4/CYP2C19 inhibitors, itraconazole/fluconazole (study A), or CYP3A4 inducer, rifampicin (study B), affects the exposure, safety/tolerability and pharmacokinetics of selumetinib and its metabolite N-desmethyl selumetinib. In study A (n = 26), subjects received a(More)
Two phase I open-label studies were conducted to investigate the pharmacokinetics (PK), safety, and tolerability of single oral doses of selumetinib in subjects with end-stage renal disease (ESRD) undergoing hemodialysis and subjects with varying degrees of hepatic impairment; both studies included a matched control group comprised of healthy individuals.(More)
PURPOSE Selumetinib (AZD6244, ARRY-142886), an oral mitogen activated kinase 1/2 inhibitor, is in clinical development for the treatment of a variety of different tumor types. Herein, we report a study that determined the distribution, metabolism, and excretion of selumetinib in healthy male volunteers. METHODS In this open-label, single-center, Phase I(More)
AIMS To evaluate the reliability of magnetic resonance imaging (MRI) performed with three-dimensional (3D) sequences in mammographically detected breast microcalcifications. METHODS During an 8-month period, a group of 28 patients with mammographically detected microcalcifications suspicious for malignancy underwent MRI. Their ages ranged from 33 to 65(More)
Breast cancer is one of the most prevalent and devastating malignant diseases in women worldwide. Fortunately, while breast cancer incidence is still increasing, its death rate is declining. This is mainly due to early diagnosis and potent therapies such as blockade of estrogen receptor- or of ErbB2 (HER2-neu) membrane receptor signaling.In recent years,(More)
