Platinum for Triple-Negative Metastatic Breast Cancer and Evaluation of p63/p73 as a Biomarker of Response

Summary

The purpose of this research study is to : * Determine how effective cisplatin or carboplatin is in slowing the time it takes for ER negative (estrogen-receptor-negative), PR negative (progesterone receptor-negative), HER2 negative (human epidermal growth factor receptor 2) breast cancer to progress. Cisplatin and carboplatin are anti-cancer chemotherapy drugs that stop cancer cells from growing abnormally and is used to treat other cancers. * Evaluate a new biomarker to help determine which breast cancers are most likely to respond to cisplatin chemotherapy The hypothesis is that Triple Negative metastatic breast cancer may be particularly sensitive to platinum, and that a subgroup of those patients may have a marker in their tumors that predicts response.
