ANCHOR LEAD: CAN A TECHNIQUE USING LIQUID NITROGEN KEEP LUNG CANCER UNDER CONTROL? ELIZABETH TRACEY REPORTS
Treating lung tumors using local techniques like radiofrequency ablation that heat up the cancerous tissue is known to be helpful in some people. Now freezing tumors is also being studied. Rosalyn Juergens, a lung cancer expert at Johns Hopkins, says there are certain advantages to the technique.
JUERGENS: One of the things that is unique to cryoablation is when you freeze something the tumor actually reacts just a little bit differently than when you heat kill something, in that some of the proteins are not degraded in the same way, so there’s some thought that maybe you could use an immune approach in somebody you use cryotherapy with because those proteins then, the immune system could react to, that’s all very preliminary, but I think that’s there’s going to be some research down the line looking at how cryotherapy can be used. :31
Juergens says more data will be available as the technique is used more widely. I’m Elizabeth Tracey reporting.
