SAN DIEGO, Calif. (March 9, 2009)Freezing kidney tumorsusing a safe minimally invasive interventional radiology treatment that kills the cancer 100 percent effectively without surgeryshould be the gold standard or first treatment option for all individuals with tumors that are 4 centimeters in size or smaller. And, this treatmentinterventional cryoablationis a viable option for people with larger tumors, according to two studies presented at the Society of Interventional Radiology's 34th Annual Scientific Meeting.
"Interventional cryoablation is as effective as laparoscopic surgery (partial nephrectomy), the current gold standard treatment, and laparoscopic cryoablation surgery for treating renal cell carcinoma," said Christos Georgiades, M.D., Ph.D., interventional radiologist at Johns Hopkins Hospital in Baltimore, Md. "We can eliminate a cancerthat once it metastasizes can be notoriously difficult to treat and has a low chance of curewith a simple outpatient procedure. Eliminating cancer at such an early stage is truly significant news for kidney cancer patients," he added.
It's important that individuals realize all their treatment optionsespecially since the incidence of kidney cancer has been steadily increasing in this country over the past 30 years, said Georgiades. Approximately 54,000 people are diagnosed with kidney cancer each yearwith nearly 13,000 dying from it annually, according to recent statistics. Most people with this cancer are older, and the overall lifetime risk of getting kidney cancer is about 1 in 75with men at higher risk than women. More than 75 percent of individuals who are diagnosed with kidney cancer have small tumors that are discovered incidentally. "Cryoablation is a great treatment option that doctors should discuss with patients early on," he explained.
The Hopkins studies, examining the safety and efficacy of percutaneous (no incision) cryoablation, show the treatment's powerful results. "Based o
