MRI in Evaluating Early Response to Chemotherapy in Women With Infiltrating Breast Cancer

Study Evaluating the Contribution of MRI for the Evaluation of Early Response to Neoadjuvant Chemotherapy in Patients With Infiltrative Breast Cancer

RATIONALE: Diagnostic procedures, such as magnetic resonance imaging (MRI), may help in learning how well chemotherapy works to kill breast cancer cells and allow doctors to plan better treatment. Drugs used in chemotherapy, such as epirubicin and docetaxel, may stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

PURPOSE: This clinical trial is studying MRI in evaluating early response to chemotherapy in women receiving chemotherapy for infiltrating breast cancer.

Pilot study (feasibility) without direct individual benefit aimed at breast cancer patients treated with neoadjuvant chemotherapy prior to local breast surgery (lumpectomy or mastectomy).
