<qa>  What is the name of the group that will receive gemcitabine and trastuzumaTreatment: Patients in this study will receive one of two treatment combinations. A computer will randomly assign patients to a treatment group. Group one will be given gemcitabine and trastuzumab. Gemcitabine will be given to patients on days 1 and 8, and trastuzumab on days 1, 8, and 15. Group two will receive gemcitabine, trastuzumab, and cisplatin. Gemcitabine and cisplatin will both be administered on days 1 and 8, and trastuzumab on days 1, 8, and 15. Each treatment cycle for both groups will last a total of 21 days. All study drugs will be administered through intravenous infusions. Several tests and exams will be given throughout the study to closely monitor patients. Thorough patient exams will be given at the beginning of each treatment cycle. Imaging tests will be done every two cycles for the first eight cycles and then every three cycles until study completion. Study treatment will be discontinued due to disease growth or unacceptable side effects.
