Lung cancer is a very life threatening cancer and one of the most difficult cancers to treat because it has a tendency to spread to other parts of the body in its early stage. Furthermore, those patients whose medical condition is complicated by presence of other diseases like acute cardiac disease besides being affected by lung cancer are unsuitable for invasive surgery required to treat lung cancer. Approximately 1.3 million people die every year due to lung cancer worldwide. In 90% patients affected with lung cancer, the cancer originates from the epithelial cells lining the lung airways known as bronchi and bronchioles.
Conventional radiation therapy treatment for lung cancers required 25 to 30 sessions of radio therapy where each session lasted for about 30 minutes.
The next generation Gated RapidArc technology introduced by Varian Medical Systems, Inc allows the doctor to detect the exact location of cancer in the lung with highest precision, while the patient is breathing. The Gated RapidArc technology uses 4-Dimensional Gated Stereotactic Body Radiosurgery to deliver full dose of radiation therapy in just 1 to 3 sessions of ten minutes each. This helps to reduce the effective treatment to just one week as compared to six weeks treatment time with conventional radiation therapy treatment.
The Gated RapidArc technology uses advanced motion management capability to ‘gate’ the radiation beam, turning it on or off in response to tumor motion during treatment. This helps to eliminate the cancerous lung tissue with high precision without causing any damage to surrounding healthy lung tissue.
The Gated RapidArc technology is superior to conventional radiation therapy and traditional invasive surgical treatments because it is completely non-invasive and leaves no scars from surgical incisions on body.
