The metastatic lung disease , which occurs when a cancer whose origin is in another part of the body spreads to the lungs, it is difficult to control and often have a poor prognosis. Therefore, any treatment to slow the progression of metastasis and improve the quality and life expectancy of patients is promising.
The study, called ECLIPSE-participated 22 people with a total of 36 tumors, which were given 27 sessions of cryoablation, which are managed to destroy tumors in 23% of patients treated with this technique. These results are preliminary, but one of the study's authors, David A. Woodrum, interventional radiologist at the Mayo Clinic in Rochester (Minnesota, USA), said that cryoablation has great potential to address cases in which an advanced stage cancer has spread to the lungs.
How cryoablation is performed
To perform cryoablation treatment of an interventional radiologist uses a small needle probe inserted through an incision in the patient's skin and targets the tumors located within the lung, guided by a medical image.
When these tumors reach the device, its end is cooled with gas at low temperatures, between -80 ° C and -120 ° C, and the ice crystals are generated which are capable of destroying cancer because they disrupt cellular function of the disease, preserving healthy lung tissue surrounding tumors, and without suffering any damage thus.
The patient undergoing this therapy is ready to resume his normal life just one day after surgery, but experts say it must subsequently attend reviews for about five years
