A year of treatment with a medicine made of an antibody and chemotherapy drug has proven highly effective in preventing stage 1 HER2-positive breast cancer from recurring in patients, a team led by Dana-Farber Cancer Institute researchers has found.

In conjunction with the trial, researchers looked for biomarkers of whether the cancer was likely to recur even after treatment with T-DM1. They found that patients with high scores on the HER2DX test – which weighs clinical factors and the activity of four genes within tumor tissue – had a greater risk of recurrence.

In this study, we evaluated T-DM1, which links trastuzumab to a powerful chemotherapy agent, for effectiveness and toxicity in this group of patients." T-DM1, known as an antibody-drug conjugate, is currently approved for post-surgical, or adjuvant, treatment of patients with HER2-positive breast cancer which remains after pre-surgical treatment, and is also approved for patients with metastatic HER2-positive breast cancer.
