RATIONALE: Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy or radiation therapy. Giving sargramostim to the stem cell donor and the patient may reduce the chance of developing graft-versus-host disease following stem cell transplantation.
PURPOSE: Clinical trial to study the effectiveness of sargramostim in decreasing graft-versus-host disease in patients who are undergoing donor stem cell transplantation for hematologic cancer or aplastic anemia.
- Determine the efficacy of sargramostim (GM-CSF) to mobilize CD34+ hematopoietic stem cells in donors and to reduce graft-vs-host disease in patients after allogeneic stem cell transplantation (SCT) for hematologic malignancy or aplastic anemia.
- Determine the safety of GM-CSF after allogeneic SCT transplantation in these patients.
OUTLINE: This is a pilot study.
- Donors: Donors receive sargramostim (GM-CSF) subcutaneously (SC) once daily on days 1-6. Donors undergo stem cell harvest on day 7.
Donors may undergo up to 3 apheresis procedures to reach the target stem cell dose and may receive additional GM-CSF prior to each collection.
- Patients: Patients receive conditioning therapy as per transplantation protocol RP98-15. Patients undergo allogeneic stem cell transplantation on day 0. Patients then receive GM-CSF SC once daily beginning on day 7 and continuing until blood counts recover.
Patients are followed weekly until day 100 and then at days 180 and 360.
PROJECTED ACCRUAL: A total of 10 patients and 10 donors will be accrued for this study.

The purpose of this study is to find out the safe dose range of the study drug in patients with myeloproliferative disorders.
The three main chronic myeloproliferative disorders are polycythemia vera (PV), essential thrombocythemia (ET) and idiopathic myelofibrosis (IMF). These are clonal neoplastic diseases cha...
RATIONALE: Drugs used in chemotherapy, such as clofarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them ...
RATIONALE: Analyzing tissue and blood samples from healthy volunteers or patients with Fanconi anemia, myeloproliferative disorders, or myeloma in the laboratory may help doctors learn mor...
This phase I/II trial studies the side effects and how well tipifarnib works in treating patients with chronic myeloid leukemia, chronic myelomonocytic leukemia, or undifferentiated myelop...
Platelet distribution width (PDW) and mean platelet volume are markers of platelet activation and have prognostic value in coronary heart diseases, as well as in cancers of solid organs. In this study...
Chronic diseases are prevalent and the leading causes of mortality. Comorbidity of substance use disorders (SUDs) and chronic diseases is understudied to inform behavioral healthcare integration.
Myeloproliferative neoplasms (MPNs) are clonal disorders divided into Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) or Ph chromosome-negative MPNs. Co-occurrence of these diseas...
This study examined pre-existing depression as a risk factor for the development of chronic spinal pain, and pre-existing chronic spinal pain as a risk factor for the development of depression. Data f...
Clonal myeloid disorders that possess both dysplastic and proliferative features but are not properly classified as either MYELODYSPLASTIC SYNDROMES or MYELOPROLIFERATIVE DISORDERS.
A myelodysplastic/myeloproliferative disorder characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to CHRONIC MYELOID LEUKEMIA, but cytogenetically lacking a PHILADELPHIA CHROMOSOME or bcr/abl fusion gene (GENES, ABL).
Conditions caused by abnormal CILIA movement in the body, usually causing KARTAGENER SYNDROME, chronic respiratory disorders, chronic SINUSITIS, and chronic OTITIS. Abnormal ciliary beating is likely due to defects in any of the 200 plus ciliary proteins, such as missing motor enzyme DYNEIN arms.
A leukemia affecting young children characterized by SPLENOMEGALY, enlarged lymph nodes, rashes, and hemorrhages. Traditionally classed as a myeloproliferative disease, it is now considered a mixed myeloproliferative-mylelodysplastic disorder.
A myelodysplastic-myeloproliferative disease characterized by monocytosis, increased monocytes in the bone marrow, variable degrees of dysplasia, but an absence of immature granulocytes in the blood.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
