About

RATIONALE: Colony-stimulating factors such as sargramostim increase the number of immune cells found in bone marrow or peripheral blood. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with sargramostim may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects of giving radiation therapy together with sargramostim and to see how well it works in treating patients with advanced solid tumors.

Full description

OBJECTIVES:

• Determine the safety of contrast-enhanced high-dose radiotherapy administered with sargramostim (GM-CSF) in patients with advanced solid malignancies.
• Determine immune response in patients treated with this regimen.
• Determine tumor response in patients treated with this regimen.

OUTLINE: Patients are stratified according to prior therapy (biopsy or simple surgery vs radical surgery, chemotherapy, or radiotherapy).

Patients receive a contrast agent intratumorally followed by a single fraction of kilovoltage radiotherapy. Beginning 24 hours after radiotherapy, patients receive sargramostim (GM-CSF) intratumorally continuously for 1 week and then subcutaneously for 2 weeks. Patients with lung tumors receive GM-CSF by inhalation twice daily for 1 week and then every other week for a total of 3 weeks of drug treatment.

Treatment may repeat in several weeks in the absence of disease progression or unacceptable toxicity.

Patients are followed every 8 weeks.

PROJECTED ACCRUAL: A total of 47 patients (12 for phase I and 35 for phase II) will be accrued for this study.

Ages: 18+ years old
