No results posted yet for this study

Summary

A major focus of recent research has been the development of effective ways of sensitizing the patient's immune system to recognize the cancer as foreign. Allogeneic stem cell transplantation represents a novel way of potentially achieving this goal. There is recent evidence that non-myeloablative allogeneic stem cell transplantation provides effective therapy for patients with metastatic renal cell carcinoma. Based on the preliminary reports from other investigators treating patient with breast and ovarian cancer, the investigators of this study would propose treating an expanded cohort of patients with any metastatic solid tumor.

The principal endpoints of the trial will include incidence of durable engraftment, quality of hematopoietic and immune reconstitution, extent of donor chimerism, incidence and severity of acute and chronic graft versus host disease (GVHD), and incidence of long-term disease free survival (DFS). The investigators will evaluate the tumor response of patients with stable or progressive disease post-transplant to donor lymphocyte infusions (DLI). The investigators will also study the effects of DLI on T-cell immunity in the recipients.

Conditions

  • Metastatic Solid Tumor

Interventions

DRUG

nonmyeloablative stem cell transplant

Conditioning includes cytoxan 60mg/kg/d on Days 6 \& 5, total dose 120mg/kg, Fludarabine 25mg/m2/d on days -5 to -1, total dose 125mg/m2. Patients with decreased cardiac or liver function pre-transplant will have their dose of cytoxan reduced by 25% - 45 mg/kg/d for 2 days or total dose of 90mg/kg. Patients will receive G-CSF (5ug/kg) to foster engraftment. PBSC progenitors will be mobilized from donor with G-CSF 5ug/kg 2x daily starting 4 days prior to stem cell collection until a target of 5-10 x106 CD34+ cells/kg is reached. Peripheral blood progenitors will be isolated from leukaphereses obtained on Days 5 \& 6 with additional collections dependent on cell yields. Peripheral blood from donors will be given to patients 1 day after cytoreduction \& immunosuppression. Immunosuppression will be tapered Day +60 if no signs of GVHD. Patients with residual non-regressing disease or mixed chimerism after day 100, who are off immunosuppression \& do not have signs of GVHD, will receive a DLI
