Evaluation of Carboplatin/Paclitaxel With and Without Trastuzumab (Herceptin) in Uterine Serous Cancer

The primary objective of this study is to estimate whether the addition of trastuzumab to paclitaxel and carboplatin chemotherapy improves progression free survival when compared to paclitaxel and carboplatin alone in Uterine Serous Papillary Carcinoma (USPC) patients overexpressing Her2/neu at 3+ level by immunohistochemistry (IHC)or positive by fluorescence in situ hybridization (FISH).
