Trastuzumab and Pertuzumab in Treating Patients With Unresectable Locally Advanced or Metastatic Breast Cancer That Did Not Respond to Previous Trastuzumab

Summary

RATIONALE: Monoclonal antibodies, such as trastuzumab and pertuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving trastuzumab together with pertuzumab may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving trastuzumab together with pertuzumab works in treating patients with unresectable locally advanced or metastatic breast cancer that did not respond to previous trastuzumab.
