See some of Becky's lastest post discussing one year vs. two years of herceptin, where she states there really is no statistically significant advantages to doing two years of therapy in early stage bc. from at least preliminary studies.

Most people do one year of Herceptin. There are even studies with nine weeks of Herceptin with similar efficacy and no cardiac risk, at least so far. Not many do two years of therapy unless there is larger disease involvement.
