Title: Percutaneous Cryoablation for Renal Cell Cancer


1
Percutaneous Cryoablation for Renal Cell Cancer
  • Christos Georgiades MD PhD
  • Assistant Professor of Radiology Surgery
  • Vascular Interventional Radiology
  • Johns Hopkins Hospital

2
Stamping Out Kidney Cancer Without Surgery
  • 55,000 patients are diagnosed with kidney cancer
    every year in the USand increasing
  • 75 of them are discovered by accident and most
    small enough to be treated by Interventional
    Radiology (Avoid Surgery)

3
How is Cryoablation done?
  1. No incision/No surgery
  2. No general anesthesia

3. Ablation needle(s) placed by Interventional
Radiologist under Image guidance
4
Our Experience
  • Treated 90 tumors (in 84 patients)
  • 2006-2008
  • 80 under sedation
  • 4 local anesthesia only
  • Never general anesthesia
  • Ages 35-90
  • Follow up every 3 months up to a year and then
    annually

5
Results
  • -Of the 90 tumors (1-10 centimeters)
  • 88 completely treated without any evidence for
    cancer (98)
  • 2 had small tumor left (1cm), one retreated with
    ablation and now no tumor left (99)
  • No patients developed new local cancer or
    metastatic cancer after ablation and none
    required surgery

Summary
  • Cryoablation by Interventional Radiology has a
    near 100 success rate in treating kidney cancers
    up to 4 and probably up to 7 centimeters in size
  • No incision/no surgery/no anesthesia
  • Most patients go home same day and can resume
    normal activities quickly
  • Fewer complications, lesser cost
  • In the unlikely case cryoablation fails, patients
    can still have the surgery they would have in the
    first place.

8
Conclusions
  • Cryo-ablation should be the first treatment
    choice for patients whose kidney cancer is 4
    centimeters or smaller.
  • and
  • If a patient wishes to avoid or cannot have
    surgery, even larger lesions can be treated (near
    100 success rate cancer up to 7 centimeters in
    size)
