Measure
Samarium-153/Stem Cell Transplant/Radiation
Samarium Sm153 Lexidronam Pentasodium (Samarium)/Stem Cell Transplant/Radiation arm: receive Ifosphamide IV in preparation for peripheral blood stem cell transplant followed by collection of stem cells. Samarium is administered after collection of peripheral blood stem cells (PBCT). Once counts recover, while receiving filgrastim daily, a second, higher dose of Samarium-153 is given, followed in 14 days by infusion of the stem cells. Filgrastim: administered daily until count recovery Ifosfamide: administered as part of Stem Cell transplant preparation. PBCT: Before administration of Samarium, collection of autologous hematopoietic stem cells Radiation: Radiation Dosimetry performed at 4, 24, 48, and 72 after each infusion of Sm-EDTMP. Samarium: First dose is administered after autologous stem cell collection. Second, higher dose, of SM-EDTMP administered after count recover. 14 days after administration of higher dose, patient undergoes autologous stem cell infusion.

Samarium Sm153 Lexidronam Pentasodium/Stem Cell Transplant/Radiation arm will receive Ifosphamide IV in preparation for peripheral blood stem cell transplant followed by stem cell collection. Samarium Sm153 Lexidronam Pentasodium is administered after collection of peripheral blood stem cells. Once counts recover, while receiving filgrastim daily, a 2nd, higher dose of Samarium-153 is given, followed in 14 days by stem cell infusion. Filgrastim: Filgrastim will be administered every day til count recovery Ifosfamide: Ifosfamide will be administered as part of Stem Cell transplant prep. Peripheral blood stem cell transplantation: Before administration of Samarium, collection of autologous hematopoietic stem cells Radiation: Radiation Dosimetry performed at 4, 24, 48, and 72 after each infusion of Sm-EDTMP. Samarium Sm 153 lexidronam pentasodium: First dose of Sm-EDTMP administered after autologous stem cell collection. Second, higher dose, of SM-EDTMP administered 7 days later.

Samarium Sm153 Lexidronam Pentasodium (\^153Sm-EDTMP)/Stem Cell Transplant/Radiation arm will receive Ifosphamide IV in preparation for peripheral blood stem cell transplant followed by stem cell harvest. \^153Sm-EDTMP is administered after collection of peripheral blood stem cells. Once counts recover, while receiving filgrastim daily, a 2nd, higher dose of \^153Sm-EDTMP is given, followed in 14 days by stem cell infusion. filgrastim: Filgrastim is administered every day til count recovery. ifosfamide: Ifosfamide is administered as part of Stem Cell transplant prep. peripheral blood stem cell harvesting: completed before administration of \^153Sm-EDTMP, collection of autologous hematopoietic stem cells. radiation: Radiation Dosimetry performed at 4, 24, 48, and 72 after each infusion of \^153Sm-EDTMP. \^153Sm-EDTMP: First dose is administered after autologous stem cell collection. Second, higher dose, is administered 1 week later.
