Doctors found that 92 percent of 3,231 women treated with the new combination chemo survived more than three years with no recurrence of their cancer.

These results make the new combination a viable alternative to anthracycline-based chemotherapy, said lead researcher Dr. Dennis Slamon, director of clinical/translational research at the Jonsson Comprehensive Cancer Center at the University of California, Los Angeles.

"It is going to be difficult to develop treatment regimens that have even better response rates than that," said Slamon, who is also chief of hematology/oncology with UCLA's department of medicine

This study was supported by funds from Roche/Genentech. Slamon has served as an adviser to both companies, including during the time period when the study was conducted.

Because the studies were presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.
