Percutaneous Renal Tumor Cryoablation Followed by Biopsy

Phase 1
Completed
Conditions
Renal Cancer
Interventions
Procedure: percutaneous cryoablation
Registration Number
NCT01012427
Lead Sponsor
Memorial Sloan Kettering Cancer Center
Brief Summary

This study is being done to test how effective cryoablation is in killing cancer cells. Cryoablation uses freezing temperatures to treat cancer. Cryoablation works by creating freezing temperatures within a needle probe. When this probe is inserted into a cancer, the freezing temperatures are used to try and kill the cancer. Unfortunately, the investigators don't know how well cryoablation works at destroying the cancer. This study will allow us to check to see how well cryoablation works for kidney cancers. After the investigators destroy the kidney cancers using cryoablation, the investigators will followup with you every 5-7 months to make sure the cryoablation worked and that the cancer was destroyed.

Exclusion Criteria

  • Women who are pregnant or breastfeeding.
  • Tumor less than 5 mm to the renal pelvis, main renal vessel, ureter, or other vital structure
  • Contraindication to MRI in patients in which it is required.
  • Coagulopathy as defined above (Inclusion Criteria).

GroupInterventionDescription
Patients with 3.0 cm or smaller renal cancerpercutaneous cryoablationThe interventions in this study are part of clinical care and include percutaneous image-guided biopsy, percutaneous renal tumor cryoablation, CT/MR imaging of the ablation bed, and repeat pathologic sampling of the tumor bed with percutaneous biopsy. The cryoablation is done as the therapeutic intervention in patients with small renal cancer. The CT/MR imaging is done to evaluate the treatment for residual disease after the ablation. The repeat biopsy (e.g. three cores) is done to confirm that the neoplasm has been eradicated. These patients have continued imaging, and if necessary, percutaneous biopsy to ensure no recurrent disease.
