The purpose of this study is to determine the preferred injection site for G-CSF and GM-CSF, which are cytokines, or growth factors. The doctor may also choose to use these growth factors in combination with chemotherapy to increase the number of stem cells in the blood. Both options are established and are effective in increasing the number of stem cells in the blood.
Patients will receive one shot under the skin twice a day for approximately 12-15 days after receiving chemotherapy through the time your cells are being collected. Patients will be randomly assigned to receive growth factors administered either to their abdomen or to their extremities. Both shots will always be given either in the abdomen or in the extremities.
