Freezing Liver and Kidney Cancer Metastasis

10/6/2018


The patient, in his 60s, underwent radiotherapy and chemotherapy for colon cancer several years ago; recently the disease was found to have metastasized in the liver. The left lobe of the liver was surgically removed; the remaining part underwent cryotherapy, an innovative medical procedure which involves freezing the metastasis using “ProSense” - equipment developed and manufactured by the Israeli company, IceCure Medical. Liquid nitrogen at a temperature of minus 160 degrees is injected into the patient via a very fine needle, creating a kind of ice ball which destroys the cancer cells.
Cryotherapy employs extreme cold to freeze and kill cells of cancerous tissue at a certain density, thus avoiding the need to surgically remove the entire organ. “The area to be frozen is very specific and focused, requiring detailed and accurate advance planning. At a temperature of minus 160 degrees the necrosis dissolves and disappears without damaging the surrounding healthy tissue. This method helps to completely clear the liver of the malignancy, "says Dr. Solomonov.
Recently studies have been published showing that as a result of cryosurgery, the immune system "attacks" and kills the cancer cells that remain. This treatment has been tried in the past on patients with breast and kidney cancer, but this is the first time in Israel that the treatment is performed in liver cancer, whose treatment is considered very complex. In cases that don’t require surgery, cryotherapy can be performed without the need for general anesthesia, without stitches or cuts in the patient's body. Because of the cold, the patient suffers no pain. It is still necessary to monitor the patient regularly, as with any oncology patient.

Dr.Ran Katz, Ziv's Director of the Urology Department, who recently performed this procedure on the kidney of a 60 year-old patient, the first such operation in Israel and the second in the world, said "The advantage to the patient is that this approach significantly reduces the risk of complications arising from surgery deep within the body; there is minimum pain, no scar tissue, no need for stitches and the patient can be released that very same day.”
This new method is suitable for patients with breast, kidney, bone, lung and liver cancer. It allows treatment in dense areas of the body which are sometimes considered problematic for surgery. This is an advanced Israeli technology, which has been used in just a number of hospitals worldwide.
