How does radiation help cancer patients?
Being able to precisely and accurately deliver radiation makes a difference in terms of controlling cancer and reducing the risk of side effects. But tumor or patient movement as a result of normal body functions, including regular breathing, filling of the bladder, or gas in the bowel can shift the tumor by a centimeter or more, which can make it challenging to accurately target the radiation and result in under- or over-dosing of the tumor. Too much radiation may increase the risk of side effects while too little may reduce the effectiveness of the treatment. Tracking the tumor’s movement — and synchronizing the delivery of radiation with that movement — helps to maximize treatment effectiveness, while minimizing dose to surrounding tissues, which can help reduce the incidence of side effects.
What is the treatment for cancer?
Radiation therapy is a treatment option for many types of tumors throughout the body. Precise and accurate delivery of radiation to the tumor is key to killing cancerous cells while minimizing dose to healthy tissues. Accurate and precise delivery helps minimize irradiation of the healthy tissues surrounding tumors and potentially the risk of side effects, which may lead to better quality of life for the patient both during and after treatment.
How does tracking target movement help with radiation?
Tracking target movement — and synchronizing the delivery of radiation with that movement — helps to maximize treatment effectiveness, while minimizing dose to surrounding tissues, which can help reduce the incidence of side effects.
What is a cyberknife?
The CyberKnife® device is the only radiosurgery or radiotherapy device that tracks and treats a moving cancer throughout the entire breathing cycle (15) . This enables an even smaller margin of normal tissue around the cancer to be treated, increasing the safety of treatment.
How does Cyberknife work?
The CyberKnife® device treats a lung cancer from up to several hundred different directions, all designed on the computer to intersect through the cancer volume, compared with 2-6 directions using “conventional” radiotherapy. Because the CyberKnife® radiation beams come from so many different directions, there is very little radiation dose to normal tissues far away from the cancer target area, again increasing the safety of the treatment, even as its power against the cancer itself is increased, due to the extreme concentration of radiation dose within the target cancer itself.
What is the treatment for stage 3 lung cancer?
The primary treatment for more advanced lung cancer patients (stage III) usually consists of chemotherapy and radiotherapy (8,9). There is also evidence that surgery added to the treatment regimen may further increase the disease-free survival (20), although this represents a very aggressive treatment approach with an added risk of complications, and is not considered the standard of care for all stage III patients.
What is the term for a disease that spreads to the lungs?
Metastatic Disease to Lungs. The lungs serve as a common site of secondary spread (known as metastatic disease, or metastases) for a wide variety of primary cancers, including colorectal cancer, upper gastrointestinal cancers, kidney cancer, sarcomas (primary soft tissue or bone cancers) and pediatric cancers.
How does lung cancer move?
Lung cancers actually move along a sometimes variable and unpredictable path during the respiratory cycle, sometimes moving several centimeters or more (9) . To compensate for this breathing motion using conventional radiotherapy, a larger volume of normal tissue around the cancer needs to be treated with full dose radiation, which limits the total dose of radiation that may be safely given.
What is the cure rate for early stage cancer?
For early stage (I, II), operable cancers in healthy patients, surgical removal is normally accepted as the treatment of choice, with reported cure rates as high as 70% or more (1, 2). If a patient has an early stage cancer, but their ability to withstand surgery is in question because of coexisting medical problems ...
Can lung cancer be spread?
Sometimes lung metastases are the only area of cancer spread, without evidence of relapse elsewhere in the body. When this is the case, if the lung metastases are not too numerous or advanced, some patients will be cured with surgical resection of their metastatic disease (16-19).

What is SBRT radiation?
SBRT is a form of hypofractionated radiation therapy. Hypofractionation entails delivering a higher dose per fraction across fewer total fractions. Hypofractionated radiation therapy , such as lung SBRT, has been proven to deliver clinical outcomes as good as conventional fractionation — while dramatically reducing both the number of treatments and the total cost of care for both patients and payers.
Why is it important to deliver radiation to the target?
Precisely delivering the prescribed radiation dose to the target is essential for optimizing long-term cancer control. Additionally, precise dose delivery reduces irradiation of healthy tissues surrounding the target.
How does radiation therapy work?
Radiation therapy is a treatment that uses high-energy X-rays (photons) to kill, shrink or control the growth of tumors. Radiation therapy works by damaging cells , disabling them from growing and dividing. The goal of any radiation treatment is to destroy cancer cells while minimizing the side effects on healthy tissue. As imaging technologies have improved over the last several decades, radiation therapy has integrated those improvements to enhance dose delivery and minimize side effects.

The goal of any radiation treatment is to destroy cancer cells while minimizing the side effects on healthy tissue. As imaging technologies have improved over the last several decades, radiation therapy has integrated those improvements to enhance dose delivery and minimize side effects.
How does radiation affect the quality of life of a patient?
The ability to deliver precise doses of radiation enables clinicians to decrease exposure to surrounding healthy tissue and minimize negative side-effects that can reduce a patient’s quality of life. Most patients resume normal activity immediately after treatment sessions.
Can a cyberknife be used for lung cancer?
CyberKnife or stereotatic radiosurgery has been used on lung tumors with pretty good results. The Japanese, together with M.D. Anderson looked into using it for stage I lung cancers in patients that are otherwise suitable candidates for surgery.#N#The bottom line is it is a new technology for lung masses. It may have a role in patients who are not surgical candidates, or perhaps someday for many patients that may even have resectable disease and good cardiopulmonary reserve.#N#Some thoracic surgeons, who are the experts in thoracic oncology, have learned to use it, evaluate its efficacy and have it in their armamentarium, so as not to loose patients to others that may use their new hammer inappropriately thinking that every tumor is a new nail.#N#Thoracic surgeons need to be poised as the gatekeepers for thoracic oncology patients for appropriate disease management.#N#Greg
Does Cyberknife remove tumors?
Cyberknife doesn't remove the tumor, it zaps it and you could still have tumor residue or dead tumor.#N#I had stereotactic radiation and had no fudicial placement, just the tattoes. Most times with stage I they prefer to do surgery to go for the cure. Doctors know all about this and use it all the time. It all depends on the doctor. Surgery was recommended for me with stage IIIA and I opted for SRS then chemo.#N#It's a personal choice as you can always find a doctor that will do it. Take care, Judy
