Mini Allo Stem Cell Transplantation for the Treatment of Solid Tumors

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
