Cryotherapy and GM-CSF in Treating Patients With Lung Metastases or Primary Lung Cancer

Lung Cancer Clinical Trial

Official title: Percutaneous Cryotherapy and Aerosolized GM-CSF for Pulmonary Metastases and Primary Lung Cancer

Status Completed

Clinical Trial Summary

RATIONALE: Cryotherapy kills tumor cells by freezing them. Giving an injection of GM-CSF before cryotherapy and inhaling GM-CSF after cryotherapy may interfere with the growth of tumor cells and shrink the tumor. Giving cryotherapy together with GM-CSF may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving cryotherapy together with GM-CSF works in treating patients with lung metastases or primary lung cancer.

Clinical Trial Description

OBJECTIVES:

Primary

• Determine whether percutaneous cryotherapy in combination with aerosolized sargramostim (GM-CSF) has any demonstrable immunologic effect in patients with pulmonary metastases or primary lung cancer.

• Determine whether any systemic immune response is detectable by the combination of cryotherapy as the antigen presentation source and GM-CSF as the immunologic adjuvant.

• Determine whether low morbidities will be maintained in patients treated with this regimen.

• Determine whether effective immunization is associated with a drop in CD4+, CD25+, LTP(TGF-β1)+, Tr cells as measured by flow cytometry or ELISPOT assay for TGF-β1-secreting cells.

Secondary

• Determine clinical response (i.e., tumor control in the dominant masses undergoing cryotherapy or in other metastatic sites) as measured by CT criteria.

• Determine the toxicity of this regimen in these patients.

OUTLINE: Patients undergo CT-guided core biopsy of a dominant lung mass and placement of at least 2 cryoprobes. Prior to initiating the freeze, patients receive an interstitial injection of sargramostim (GM-CSF) near the tumor. Patients then undergo percutaneous cryotherapy over 2 hours utilizing a freeze-thaw-freeze cycle. Beginning within 3 days of cryotherapy, patients receive aerosolized GM-CSF twice daily for 1 week. Beginning on day 32, patients may elect to undergo a second course of treatment as described above in the absence of disease progression or unacceptable toxicity.

Patients undergo blood and tumor tissue collection at baseline and periodically during study for immunological correlative studies. Peripheral blood mononuclear cells isolated from blood samples are analyzed for antigen-specific CD4-positive or CD8-positive T-cell response by flow cytometry or by TGF-β1 ELISPOT assay to measure TGF-β1- secreting cells. Tumor cell lysates extracted from tumor samples are pulsed with autologous dendritic cells and analyzed by ELISPOT assay to measure T-cell reactivity in tumor specimens.

After completion of study therapy, patients are followed at 6 and 12 months. ;
