  1. Cryoablation Minimally-Invasive, Non-Surgical Treatment for Kidney Cancer The Johns Hopkins Hospital

  2. Kidney Cancer • 52000 new cases per year in the USA • 75% are incidentally discovered when patients are examined for other reasons. Because of utilization of Cat scans, Ultrasounds and MRIs by Radiologists • This Incidental detection results in improved long term survival/cure rate because many caught early- now70% (40% in 1960’s)

  3. Kidney Cancer in the US 52000

  4. Treatment options • Removal of whole kidney • Removal of tumor and surrounding part of kidney • Open surgery vs laparoscopic surgery or ablation • Percutaneous ablation

  5. Percutaneous Cryoablation • A thin, needle-like, probe is directed from the skin into the tumor NO INCISION or SURGERY Under direct visualization using a CAT scan or Ultrasound • The probe freezes the tumor to lethal sub-zero temperatures • Probe is thawed and removed • Under minimal sedation NO GENERAL ANESTHESIA

  6. Size of Kidney Cancers Treated with Cryoablation

  7. Percent of kidney cancers completely treated (Success rate) 1-year follow up < 1-year follow up

  8. What happens to the Cancer after treatment?

  9. Before After

  10. Minimally-Invasive Cryoablation for Kidney Cancer • Cryoablation can be a curative treatment option for patients with kidney cancer • 4 cm or less-success rate is 97% • * Even patients with larger tumors can benefit from this procedure especially those who cannot have general anesthesia or surgery • * Half of patients go home same day, • the rest after one night’s stay
