简要总结
Primary Objectives:
- To assess the feasibility of mini-allogeneic Peripheral Blood Progenitor Cell (PBPC) transplantation in patients with recurrent or metastatic breast cancer.
- To determine the success rate (complete remission without severe toxicity or death) at 100 days after the transplant and long-term progression free survival (PFS) rate.
- To examine the graft vs. breast cancer effect of allogeneic PBPC transplantation.
详细描述
If tumors shrink by standard-dose chemotherapy, patients will receive moderate dose chemotherapy to prepare for the blood stem cell transplant. The drug fludarabine will be given by vein on days 1-5. The drug melphalan will be given by vein on days 4 and 5. Day 6 will be a rest day; no drugs will be given. The blood stem cell transplant will be given on day 7. Bone marrow from the matched donor may be used instead of blood stem cells, particularly for unrelated donors. A catheter (tube) will be placed in a large vein in the chest to reduce the number of times patients are stuck with a needle.
Researchers will collect blood stem cells from your brother or sister or from an unrelated donor using granulocyte colony-stimulating factor (G-CSF) before receiving high-dose chemotherapy. You will need to have enough stem cells before transplantation.
The drugs G-CSG, tacrolimus, and methotrexate will be given to ease side effects and help blood counts return to normal after the transplant. G-CSF is given as a shot under the skin, starting the day from transplant and continuing until the white blood cell count is normal. Tacrolimus is given by vein or by mouth for 4 to 7 months; during the last month it is given, the dose will be tapered off. Methotrexate is given by vein on days 1, 3, and 6 after transplant. Day 11 of methotrexate is given additionally if a donor is unrelated. Blood transfusions may be needed also.
Antithymocyte globulin will be given to patients who receive blood or bone marrow from donors whose cells do exactly match the patients or from unrelated donors.
Sometimes the transplanted cells attack the normal cells in the patient's body instead of the cancer cells. This is called graft-vs-host disease (GVHD). The drug methylprednisolone will be given by vein or by mouth to fight GVHD is it occurs.

结局指标
主要结局
Number of Participants With Tumor Response
时间窗: Baseline to measured progressive disease (post study follow-up period 24 months starting from the date of the last drug administration). Data collected every 4 months.
Best response recorded from start of treatment until disease progression/recurrence using World Health Organization (WHO) criteria of Complete Response: disappearance of all disease/symptoms \> 4 weeks; Partial response, \> 50% reduction in sum of products of diameters of each measurable lesion for more than 4 weeks; Stable Disease, no change in tumor size; and Progressive Disease, appearance of new lesions or \> 25% increase in sum of products of diameters of any measurable lesions.
Overall Survival
时间窗: Transplant until death.
Survival duration was calculated from time of transplantation by number of days.
Time to Progressive Disease
时间窗: Transplant to Progression.
Progression-free was measured, by days, at time from transplantation to development to disease or death from any cause, which ever occurred first.
Grade II-IV Toxicity
时间窗: Up to one year.
Non-hematopoietic toxicity within the first year of transplantation, acute Graft versus Host Disease (GVHD) above National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Grade I and chronic above Grade I are reported by participant incidence. Broad classification of adverse events (AE) categories based on anatomy and/or pathophysiology; within each category, AEs are listed accompanied by their descriptions of severity (Grade, Grade 1 least severe).
Number of Participants With Acute or Chronic GVHD And Response to Therapy
时间窗: Transplant to 1 year post transplant
Participants diagnosed with Graft versus Host Disease (GVHD) post transplant were divided into either acute (aGVHD), normally observed within the first 100 days post-transplant; and chronic GVHD (cGVHD) cases, normally occur after 100 days, then evaluated and scored according to standard criteria from "Consensus conference on acute GVHD grading," Bone Marrow Transplant 1995; 15: 825-828, noted is type of case and whether responds to therapy.
