Lung Cancer: Radiofrequency Ablation (RFA) of Lung Tumors

Posted on 10/19/2009 10:54:34 PM PDT by neverdem

Introduction: Surgery is the established treatment for early stage primary lung cancers (cancer that started in lung) or limited secondary cancers (cancer that started outside and spread to lung, also known as metastases or metastatic cancer). External beam radiation is an alternative local therapy to surgery, particularly for patients who are not candidates for surgery due to other medical conditions. Thermal ablation, using either heat or cold, is a newer treatment to destroy cells in lung tumors. Heat is most commonly used, and is referred to as Radiofrequency Ablation (RFA). RFA of tumors has gained significant interest and acceptance in the last decade due to its potential to produce a large volume of cancer cell death in a controlled fashion.

What is RFA?

RFA stands for Radio Frequency Ablation. RFA is successfully used to treat certain tumors of lung, liver, kidney, and bone. Radiofrequency energy oscillation agitates cells thereby increasing the frictional heating with in tissues resulting in cell death. The feasibility of lung RFA has been demonstrated in animals (1-3), and the feasibility, safety and long term efficacy of lung RFA to treat tumors have been reported in humans, both in the United States and internationally (4-13). During the RFA procedure, rapidly alternating current is applied with a frequency in the range of 460-500 kHz through the RFA electrode (14). The alternating current causes movement of ions in the tissue resulting in tissue heating. Applying a temperature greater than 50 degrees centigrade for five minutes results in tumor cell death. Too high a temperature is not desirable as it will cause charring and gas formation immediately adjacent to the electrode and prevent the homogeneous heating of the entire tumor. During RFA, reaching a temperature of 60-100 degrees centigrade within the tumor is generally desired, as charring and gas formation...

I think the Kanzius machine holds the most promise, if we could find a way to an inert mental to be taken in by cancer cells then we could have a near 100% cure rate for all cancer.

On Fox the other morning a Doctor who had cancer and was given only two weeks to live experimented putting two drugs together. That was nine years ago. Sounded very interesting for anyone with cancer. http://neoplas.org/

Anything done to help lung cancer victims is good — there’s too little attention paid to the disease — and too little money invested in a cure. Thanks for posting this.

RFA is also used in cardiothoracic surgery to ablate lesions.

I've had transcathetor RFA three times to correct a heart arrhythmia. Amazing stuff.

It’s a much less invasive alternative to surgery.

Do a little research on the GB-4000. They aren’t very expensive and they work.
