| Brief Title ICMJE | Metformin Plus Neoadjuvant Chemotherapy in Breast Cancer | ||||||||
| Official Title ICMJE | Clinical Phase II, Randomized, Double Blind Trial, to Evaluate the Efficacy of Metformin and Chemotherapy Versus Placebo Nad Chemotherapy in Neoadjuvant Setting for Locally Advanced Breast Cancer | ||||||||
| Brief Summary | Background Obesity and overweight are well known risk factors for breast cancer and also are associated with higher recurrence and mortality rates. Main goal of this study is to evaluate the efficacy of metformin plus chemotherapy in terms of pathologic complete response in comparison with placebo plus the same chemotherapy regimen Design: Randomized, double blind, clinical trial. This study will be performed at National Cancer Institute of Mexico City, at breast cancer unit. Patients with ER+ or PR+, HER2 negative, breast cancer are candidates to participate. After completion of chemotherapy all patients will have a breast surgery to assess pathologic response. Complete pathologic response is defined as the abscence of malignant cells in breast tissue and lymph nodes. The presence of DCIS is considered as pCR |

| Detailed Description | Definitions Luminal A: tumors ER + PR + HER2 Negative and Ki67 <14% Luminal B: tumors ER +/-, PR +/-, HER2 negative and Ki67 >15% Complete pathologic response is defined as the abscence of malignant cells in breast tissue and lymph nodes. The presence of DCIS is considered as pCR |
