About

RATIONALE: Cryotherapy kills tumor cells by freezing them. Giving cryotherapy before surgery may kill more tumor cells.

PURPOSE: This phase I trial is studying how well cryotherapy works in treating patients with primary stage I non-small cell lung cancer or lung metastasis.

Full description

OBJECTIVES:

Primary

• Evaluate the histologic result of treating patients with primary stage I non-small cell lung cancer or lung metastasis after neoadjuvant percutaneous cryotherapy (PTC).

Secondary

• Provide a qualitative assessment of the histology from the ablation and tumor margins, comparing histologic observations with imaging-enhancement patterns by CT or PET scan before and after PTC.

OUTLINE: Patients undergo CT-guided percutaneous cryotherapy (PTC) over 2 hours. Approximately 3 weeks after completion of PTC, patients undergo thoracotomy consisting of lobectomy of the primary lung cancer or wedge resection with adequate margin for the metastatic lesion, and mediastinal lymph node dissection.

Tissue samples from ablation and tumor margins are collected during thoracotomy and compared with imaging-enhanced patterns of CT or PET scans taken at baseline and after PTC.

After completion of study therapy, patients are followed periodically for 6 months.

Enrollment: 9 patients

Sex: All

Ages: 18 to 120 years old

Volunteers: No Healthy Volunteers
