Kidney cancer: cryotherapy rather than ablation
A team at Rangueil University Hospital in Toulouse has successfully treated by percutaneous cryotherapy five patients with kidney cancer. This innovative and gentle technique destroys diseased tissue by applying extreme cold to the tumor.
After the one in Strasbourg where 20 interventions have already been performed, the University Hospital of Toulouse is among the first centers to have this technique of cryotherapy, whose main advantage is to avoid the use of kidney removal. Thus the renal function is then preserved.
Since the 1970s, the incidence of kidney cancer has been increasing. Currently, in France, 8,500 new cases are diagnosed each year.
While the reference treatment was, until recently, the complete removal of the tumor-bearing kidney, the development of new techniques can improve patient survival and preserve the organ. This is particularly the case of partial nephrectomy (partial removal of the kidney) or lumpectomy (removal of the single tumor).
As for cryotherapy, "it is a real added value in the management of patients with renal tumors," said Toulouse Hospitals. The intervention is less traumatic, the follow-up simpler and the duration of hospitalization shorter.
