Welcome Richard BellAndrew Love Cancer Centre, Geelong, Australia
Contributions of Roche Oncology • Substantial clinical trial programme across the spectrum of breast cancer: • paclitaxel ± Avastin as first-line treatment for MBC • Xeloda + docetaxel (XT) vs docetaxel for MBC • HERceptin Adjuvant trial (HERA) • Commitment to the continued development of existing products • Continued exploration of new treatments
Current investigative programme • Different disease settings • neoadjuvant, adjuvant and metastatic • Combinations of chemotherapy with biologic agents • Combinations of biologic agents • Evaluating new treatment strategies
