BACKGROUND: A new surgical technique now being offered at the University of Michigan Comprehensive Cancer Center in Ann Arbor is helping people with early stage lung cancer recover more quickly with less pain. Among the first 1,100 patients to receive the new surgery, mortality rates were below 1 percent, with minimal complications.

THE TECHNIQUE: The new technique is called thoracoscopic lobectomy. The surgeon makes three small incisions, each about an inch long. A camera is then inserted through a fourth incision just 1/5 of an inch long. The camera allows the surgeon to see inside the chest to perform the surgery and remove the cancerous nodule. The procedure is ideal for the early stages of lung cancer, when the nodule is smaller than two inches, has not invaded the chest wall, and has not spread to distant organs.

BENEFITS: Unlike conventional lung surgeries, very little muscle has to be cut and the rib cage does not need to be spread. As a result, patients leave the hospital in half the time than they would with conventional lung surgery, with less need for narcotic painkillers. They can even return to work in only two weeks. Traditional lung cancer surgery is called a thoractomy, in which the surgeon cuts through the muscles into the chest and spreads open the ribs to reveal the lungs. It requires a large incision over seven inches long, and recovery is slow and painful. Because the technique removes the entire lobe, and can also be used to remove a portion of the lung (called a wedge resection), it may also eliminate the need for needle biopsies or additional surgeries.

ABOUT LUNG CANCER: The lungs are sponge-like organs found in the chest cavity. When we breathe, air goes into the lung through the windpipe (trachea), which is divided into smaller branches leading to tiny air sacs called alveoli. These contain tiny blood vessels that absorb oxygen from the inhaled air into the bloodstream and release carbon dioxide. Most lung cancers start in the lining of the smaller branches, developing over several years. The cancer cells produce chemicals that cause new blood vessels to form, which feed the cells until they form a tumor. Cells can break away from the original tumor and spread to other parts of the body, a process called metastasis. About 90 percent of lung cancers develop in smokers or former smokers. Symptoms of lung cancer include coughing up blood, shortness of breath or wheezing; chest pain; repeated chest infections, asthma, or fluid around the lung; and swelling in the neck or face.
