Welcome Chris Twelves University of Leeds and Bradford NHS TrustUK
Evolution of treatment: new opportunities for Xeloda in breast cancer (BC) • Neoadjuvant BC • proof of concept for model biologics and targeted therapies • Adjuvant BC • replace 5-FU in standard anthracycline-based regimens • as an alternative to other cytotoxics • Metastatic BC • increasing adjuvant use of anthracyclines-taxanes • need for effective, well tolerated and convenient regimens • sequential monotherapies • doublet and triplet combinations ± Herceptin • all oral combinations
Evolution of treatment: new opportunities for Xeloda in colorectal cancer • Adjuvant colon cancer • introduction of chemotherapy combinations • need to select appropriate (effective, well tolerated, convenient) treatment for each patient • Metastatic colorectal cancer • increasing use of complex chemotherapy combinations ± biologicals and/or small molecules • need for effective, well tolerated and convenient regimens that are cost effective

Innovations in early breast cancer (BC) management with Xeloda Heikki Joensuu Helsinki University Central Hospital Helsinki, Finland
Rationale for integrating Xeloda into the treatment of early BC • High single-agent efficacy in metastatic BC (MBC) • objective response rate 15–28% in five clinical trials of pretreated MBC • median duration of response ≈8 months • Active in combination regimens • Xeloda extends overall survival when combined with Taxotere1 • interesting partner to build on improved outcomes achieved with taxanes in early BC treatment2,3 • Favorable safety profile, with minimal myelosuppression and alopecia 1O’Shaughnessy J et al.
