A Randomized Phase III Post-Operative Trial of Platinum Based Chemotherapy vs. Observation in Patients with Residual Triple-Negative Basal-Like Breast Cancer Following Neoadjuvant Chemotherapy.

This randomized phase III trial studies how well cisplatin or carboplatin (platinum based chemotherapy) works compared to observation in treating patients with remaining (residual) basal-like triple-negative breast cancer following chemotherapy after surgery (neoadjuvant). Drugs used in chemotherapy, such as cisplatin and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether cisplatin or carboplatin is more effective than observation in treating patients with residual triple negative basal-like breast cancer.

Key Eligibility:
• Female and male patients must have histologically confirmed triple negative (estrogen receptor negative [ER-]/progesterone receptor negative [PR-]/human epidermal growth factor receptor-2 negative [HER2-]) invasive breast cancer, clinical stage II-III at diagnosis (American Joint Committee on Cancer [AJCC] 7th edition) based on initial evaluation by clinical examination and/or breast imaging.
• Patients must have completed neoadjuvant taxane +/- anthracycline; patients must NOT have received cisplatin or carboplatin as part of their neoadjuvant therapy regimen.
