Filter by:RATIONALE: The influenza vaccine may help prevent flu in patients who have undergone stem cell transplant. PURPOSE: This clinical trial is studying how well the influenza vaccine works in preventing flu in patients who have undergone stem cell transplant and in healthy volunteers.
RATIONALE: Probiotics, such as Lactobacillus, may be effective in preventing infections in patients with suppressed immune systems. PURPOSE: This phase I trial is studying the side effects and how well giving enteral nutrition, including Lactobacillus, works in preventing infections in patients undergoing donor stem cell transplant for hematologic cancer or myelodysplastic syndrome.
This is a clinical research study designed to evaluate whether the administration of a vaccine to patients after transplant consisting of a minor histocompatibility antigen (mHag peptide) mixed with G-CSF (a drug intended to stimulate the immune system) can stimulate increased graft versus leukemia (GVL) responses without causing graft-versus-host disease (GVHD).
RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment. PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.
RATIONALE: Studying blood samples from cancer patients undergoing pain treatment in the laboratory may help doctors learn more about how pain drugs work in the body. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at fentanyl in patients with cancer.
This is a Phase I study designed to determine the MTD and assess the toxicity associated with clofarabine followed by fractionated cyclophosphamide in patients > 1 year of age or < 21 years of age with relapsed or refractory acute leukemias. There will be 25 to 35 patients enrolled. Cohorts of 3 to 6 patients each will receive escalated doses of clofarabine followed by fractionated cyclophosphamide until the MTD is reached. There will be no intra-patient dose escalation. Single-agent cyclophosphamide will be administered by 2-hour IVI on Day 0 of cycle 1. On Days 1, 2, and 3 and Days 8, 9, and 10 clofarabine will be administered by IVI 2 hours before each dose of cyclophosphamide (see the treatment schema below). A cycle is defined as 28 days.
RATIONALE: Giving low doses of chemotherapy before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving umbilical cord blood transplant together with fludarabine, melphalan, and antithymocyte globulin works in treating patients with hematologic cancer.
RATIONALE: Giving low doses of chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving a monoclonal antibody, such as alemtuzumab, before transplant and tacrolimus and methotrexate after transplant may stop this from happening. PURPOSE: This phase II trial is studying the side effects of donor stem cell transplant and to see how well it works in treating patients with high-risk hematologic cancer.
RATIONALE: Studying a diagnostic biomarker test in blood samples from patients who have undergone a donor stem cell transplant for cancer may help doctors plan treatment. PURPOSE: This clinical trial is studying an immunologic diagnostic blood test to see how well it works in predicting side-effects in patients with hematologic cancer or other disorders who have undergone a donor stem cell transplant.
RATIONALE: Giving total marrow and total lymph node irradiation together with low doses of chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase I trial is studying the side effects and best dose of total marrow and total lymph node irradiation when given together with fludarabine and melphalan followed by donor stem cell transplant in treating patients with advanced hematological cancer that has not responded to treatment.
