Surgery is a treatment option in lung cancer only when the patient is healthy enough for surgery, and the:
- has been found early,
- is able to be completely removed safely, and
- has not spread within the chest or to other organs
Patients should discuss with their health care team whether surgery is the best option for them. Lung cancer surgery is a complex operation that can have serious consequences. Therefore, it should be done by a thoracic surgeon—a surgeon specially trained in operating on people with lung cancer. Patients often seek a second opinion with a thoracic surgeon when considering surgery.
What is the goal of surgery to treat lung cancer?
The goal of surgery is to remove the lung tumor with a border of healthy tissue surrounding the tumor. If there is no cancer found in the tissue surrounding the tumor, it means that the tumor was removed with clear margins.
During surgery, nearby 4in the lung and middle portion of the chest are also removed to check them for cancer, and to help determine whether further treatment is necessary.
What are the different types of surgery used in lung cancer?
The type of surgery the doctor recommends depends on the size and location of the tumor and on how well the patient’s lungs are working. If a patient’s lungs are healthy, a lobectomy is most commonly the preferred operation. Removing more of the lung tissue may provide a better chance to cure the lung cancer.
Following are descriptions of different approaches that may be used.
Lobectomy is the removal of one of the fiveof the lung. When non-small cell lung cancer (NSCLC) is detected at a very early stage, a lobectomy is the most effective type of surgery, even when the lung tumor is very small.
In a wedge resection, the surgeon removes the tumor and a small rim of normal tissue surrounding it. This is done if the surgeon is unable to remove an entire lobe of the lung. A wedge resection may also be performed if the patient has alesion. A wedge resection is only recommended for treating the smallest lung cancers (less than 2 cm in diameter) or for patients with other medical conditions that make removing the entire lobe dangerous.
A segmentectomy removes one of the small segments within the lobes of the lung that contains a cancer. The amount of lung tissue removed is between what is removed in a lobectomy and in a wedge resection. Like wedge resection, it is recommended only for treatingthat are less than 2 cm wide and for elderly patients or those with other medical conditions that make removing the entire lobe dangerous.
The surgical removal of the entire lung. This type of surgery is usually required if the tumor is very large or is close to the center of the chest.
This surgery is used for tumors that involve the large airways. The tumor and a portion of the airway are removed and the ends of the airway are rejoined so remaining lobes can be left in place. A surgeon may do this operation instead of a pneumonectomy to preserve more lung function.1,3,4
What are the different techniques used to perform lung surgery?
A thoracoscopy is a minimally invasive surgery that uses small incisions and small instruments to examine and perform operations in the inside of the chest. It is also known as video-assisted thoracic surgery, or VATS. This procedure requires a great deal of technical skill and should only be performed by a surgeon who has specific training and experience in it.
VATS to remove lung cancer is done in an operating room under general anesthesia. During the operation, a thin tube with a light and a tiny video camera on the end is placed through a small incision on the side of the chest. The view inside the chest is transmitted onto a television monitor. The surgeon can look around freely inside the chest, watching the image on the TV screen. One or two other small incisions are used for long instruments that are used to do the same operation that would be done using a thoracotomy. If a lobectomy or pneumonectomy is done, one of the incisions will be enlarged to allow the tumor and lung tissue to be removed.
Since only small incisions are needed in a VATS, there is less pain after the surgery and a more rapid recovery. Chest tubes are required for most VATS procedures, and patients typically remain in the hospital for a few days until the drainage of fluid and air subsides. Research has shown that the cure rate after a VATS is similar to surgery done with a larger incision or a thoracotomy. However, less pain, fewer complications, and shorter hospital stays have been found with VATS.3,5
A newer type of operation known as robotic-assisted surgery is being performed at some large cancer centers in the United States. In this approach, a doctor sits at a control panel, inside the operating room, using robotic arms to maneuver long surgical instruments.6 Robotic surgery requires special training and expertise. Results from robotic-assisted lung cancer operations are very similar to those with VATS.
What to expect after lung cancer surgery
Length of hospital stay
How long a person needs to stay in the hospital after surgery will depend on:
- Which type of surgery was done
- The patient's overall health before surgery
- The patient's lung function after surgery
- Post-surgical complications, if any
Depending on the type of surgery a person has and how big the incision, the patient's chest and back may be painful for several weeks or longer after surgery. The doctor can prescribe pain medicines that will help. There are some other things people can do at home to help lessen the pain (see Living Well With Lung Cancer). is another common side effect, especially of traditional thoracotomy.
One or more chest tubes are typically placed during surgery to keep the patient's chestfree of fluid, blood, and air that collect after lung surgery. The tubes will be connected to a machine that gently suctions the fluid from the chest. These tubes are left in place until the fluid and air have stopped draining. Usually this takes a few days.
A patient should expect to feel short of breath after lung surgery. The extent of this depends on how much of the lung was removed and how much pain the patient is experiencing. After a portion of a lung is removed, the remaining lung tissue can expand over time and make it easier to breathe.
A respiratory therapist will help the patient with breathing treatments after surgery. These treatments may include:
- Deep breathing exercises
- The use of a to encourage deep breathing and expand the lungs
- Medicines to help open the airways
If respiratory treatments are not prescribed, the patient should ask his or her doctor for a consultation.
What are the risks of lung cancer surgery?
Lung cancer surgery carries risks like any surgery, including:
- Blood clot
- Allergic reaction to anesthesia medications
Other risks that specifically may occur after lung surgery include:
- Failure of the lung to expand
- Injury to the lungs, heart, or blood vessels
- Persistent pain
- Pneumothorax (air or air collection in the space that separates the lung from the chest)
- Pleural effusion (fluid collection in the space around the lung in the chest)
- Pneumonia (bacterial infection in one of the remaining lobes of the lungs)1,5,6
