'Freezing' Kidney Tumors Nonsurgically Is Effective, Safe And Less Expensive Than Laparoscopic Surgery
Research presented today at
the Society of Interventional Radiology's 32nd Annual Scientific Meeting
shows that the nonsurgical image-guided treatment of kidney tumors --
cryoablation - - is as effective as the laparoscopic technique in viable
candidates. The comparative trial shows that percutaneous cryoablation
results in a slightly lower recurrence rate of the tumor, a shorter
hospital stay, no major complications, and a 59.5 percent lower hospital
cost than the laparoscopic treatment. During cryoablation argon gas enters
the tip of the probe and extracts heat from the surrounding cells,
resulting in an "ice ball" that freezes and kills the tumor. The
nonsurgical treatment spares the majority of the healthy kidney tissue and
can be repeated as often as needed. This interventional treatment had no
major complications as opposed to the surgical group, which experienced
complications in six percent of those studied.
The radiologist uses imaging to pinpoint the tumor, and then inserts
the cryoprobe through the skin, similar to the way a biopsy is performed.
This can be performed under general anesthesia, but is often possible with
only local anesthesia and conscious sedation. By using imaging the
radiologist can avoid going through any adjacent structures or harming
healthy tissue. If necessary, adjacent structures can be displaced prior to
the ablation to minimize collateral damage. Laparoscopy, on the other hand,
requires general anesthesia, as well as multiple abdominal incisions to
allow access for the surgical instruments. It is also associated with a
longer recovery time.
"This early stage research indicates that percutaneous cryoablation in
the appropriate patient population can effectively kill tumors, while also
offering patients a shorter hospital stay, a faster recovery, and an
excellent safety profile, all at a lower cost than laparoscopy," noted
study author J. Louis Hinshaw, M.D., of the University of Wisconsin.
"Unfortunately, not all patients are viable candidates for percutaneous
ablation and we work closely with our urology colleagues to ensure that
each patient receives the most appropriate treatment."
The FDA has approved both radiofrequency ablation and cryoablation for
use in soft tissue tumors, of which renal cell carcinoma is one.
"We are excited about this study because it offers patients with renal
cell carcinoma a less traumatic treatment that can be repeated as needed,"
Hinshaw added. "Depending on the stage of the disease, this procedure can
be curative, but can also be used for palliative treatment in some
settings."
In the study, 19 percutanous and 48 laparoscopic cryoablations were
performed and compared. The results indicated:
-- Laparoscopic cryoablation had a slightly higher tumor recurrence rate (
12.5 vs. 10.5 percent)
-- Percutaneous cryoablation required fewer days in the hospital (1.1 vs.
2.5)
-- Percutaneous cryoablation had no major complications (0 vs. 6.3
percent)
-- Percutaneous cryoablation cost 59.5 percent less than laparoscopic
approach
About Kidney Cancer
Kidney cancer is the eighth most common cancer in men and the tenth in
women. The most common type of kidney cancer is renal cell carcinoma that
forms in the lining of the renal tubules in the kidney that filter the
blood and produce urine. Approximately eighty-five percent of kidney tumors
are renal cell carcinomas.
Surgical removal of tumors confined to the kidney offers the best
chance for a cure. Unfortunately, some patients may not tolerate surgery
due to underlying medical conditions, and some patients, particularly those
with small tumors, may not want to have surgery for their cancer. In this
group of patients, minimally invasive image-guided therapies offer a less
invasive option. These interventional treatments can also offer valuable
benefits to some patients with advanced or metastatic renal cell carcinoma.
Chemotherapy drugs and radiation are generally ineffective at curing kidney
cancer.
More than 32,000 Americans each year are diagnosed with kidney cancer
-- many of them don't have symptoms. Typically, those with kidney cancer
are past the age of 40 and are twice as likely to be men. Other risk
factors include smoking, obesity, high blood pressure, long-term dialysis
and Von Hippel- Lindau syndrome.
About the Society of Interventional Radiology
Interventional radiologists are board-certified physicians who
specialize in minimally invasive, targeted treatments. They offer the most
in-depth knowledge of the least invasive treatments available coupled with
diagnostic and clinical experience across all specialties. They use X-rays,
MRI and other imaging to advance a catheter in the body, usually in an
artery, to treat at the source of the disease nonsurgically. As the
inventors of peripheral angioplasty and the catheter-delivered stent,
interventional radiologists pioneered minimally invasive modern medicine,
and provide treatments that offer less risk, less pain and less recovery
time compared to open surgery. More information can be found at
