简要总结
RATIONALE: Colony stimulating factors, such as GM CSF, may increase the number of immune cells found in bone marrow or peripheral blood. It is not yet known which GM-CSF regimen is more effective in treating patients with prostate cancer.
PURPOSE: This randomized phase II trial is studying how well GM-CSF works in treating patients with relapsed prostate cancer.
详细描述
OBJECTIVES:
Primary
- To determine the ability of sargramostim (GM-CSF) to increase the number and activation of dendritic cells (DC) in patients with biochemically relapsed prostate cancer.
Secondary
- To determine the effect of administration schedule and hormonal state on sargramostim-induced DC number and activation in these patients.
- To correlate the effects of sargramostim on DC number and activation with effects on prostate-specific antigen (PSA) modulation.
- To determine whether sargramostim administration generates antiprostate cancer immune responses in these patients.

入选标准
- •DISEASE CHARACTERISTICS:
- •Histologically confirmed adenocarcinoma of the prostate
- •Non-metastatic, recurrent systemic disease as manifested by a rising PSA, defined as ≥ 2 consecutive rises in PSA to be documented over a reference value (measure 1)
- •The first rising PSA (measure 2) should be at taken ≥ 14 days after the reference value
- •A third confirmatory PSA measure is required (second beyond the reference level) to be greater than the second, and it must be obtained ≥ 14 days after the second measure
- •If this is not the case, a fourth PSA is required to be taken and be greater than the second measure
- •No local-only relapse
- •Must have undergone prior definitive therapy for prostate cancer consisting of external beam radiotherapy, brachytherapy (with or without external beam radiotherapy), or radical prostatectomy (with or without adjuvant androgen ablation)
- •Patients who have not undergone definitive therapy as above or who have undergone hormonal therapy alone are not eligible
- •No evidence of metastases on bone or CT scan
- •PATIENT CHARACTERISTICS:
- •ECOG performance status 0-1
- •Leukocytes ≥ 3,000/μl
- •Absolute neutrophil count ≥ 1,500/μl
- •Platelets ≥ 100,000/μl
- •Total bilirubin normal
- •AST and ALT ≤ 2.5 times upper limit of normal (ULN)
- •Creatinine ≤ 1.5 times ULN
- •No active thrombophlebitis or disseminated intravascular coagulopathy
- •No history of pulmonary embolus
- •No history of immunodeficiency or autoimmune diseases
- •No uncontrolled intercurrent illness, including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- •PRIOR CONCURRENT THERAPY:
- •See Disease Characteristics
- •No prior systemic chemotherapy for any reason
- •No concurrent anticoagulation therapy (i.e., therapeutic coumadin)
- •Prophylactic anticoagulation (e.g., aspirin) allowed
- •No concurrent systemic corticosteroids or other immunosuppressives
- •Inhaled or topical steroids allowed

研究组 & 干预措施
Arm II: sargramostim (3xweek)
Patients receive GM-CSF SC three times weekly for 4 weeks. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.
干预措施: sargramostim (Biological)
Arm I: sargramostim (days1-14)
Patients receive sargramostim (GM-CSF) subcutaneously (SC) on days 1-14. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.
干预措施: sargramostim (Biological)
