Stronger role for a breast cancer drug

Lapatinib shows utility for patients with a particularly troublesome form of the cancer

Patients with metastatic breast cancer are destined to return to chemotherapy, and this drug combination seems to significantly delay that day for patients who have a certain form of the disease, says medical oncologist Stephen Johnston of the Royal Marsden NHS Foundation Trust in London.

He presented the findings December 11 at the San Antonio Breast Cancer Symposium.
