Treating Lung Cancer - Non-Small Cell TOPICS

Surgery for non-small cell lung cancer

Surgery to remove the cancer (often along with other treatments) may be an option for early stage non-small cell lung cancer (NSCLC). If surgery can be done, it provides the best chance to cure NSCLC. Lung cancer surgery is a complex operation that can have serious consequences, so it should be done by a surgeon who has a lot of experience operating on lung cancers.

If your doctor thinks the lung cancer can be treated with surgery, pulmonary function tests will be done beforehand to see if you would still have enough healthy lung tissue left after surgery. Other tests will check the function of your heart and other organs to be sure you’re healthy enough for surgery.

Because more advanced stage lung cancers are not helped by surgery, your doctor will also want to know if the cancer has already spread to the lymph nodes between the lungs. This can be done before surgery with mediastinoscopy or with some of the other techniques described in the section “How is non-small cell lung cancer diagnosed?

Types of lung surgery

Different operations can be used to treat (and possibly cure) non-small cell lung cancer. These operations require general anesthesia (where you are in a deep sleep) and are usually done through a surgical incision between the ribs in the side of the chest (called a thoracotomy).

  • Pneumonectomy: an entire lung is removed in this surgery.
  • Lobectomy: an entire section (lobe) of a lung is removed in this surgery.
  • Segmentectomy or wedge resection: part of a lobe is removed in this surgery.

Another type of operation, known as a sleeve resection, may be used to treat some cancers in large airways in the lungs. If you think of the large airway with a tumor as similar to the sleeve of a shirt with a stain an inch or 2 above the wrist, the sleeve resection would be like cutting across the sleeve above and below the stain and sewing the cuff back onto the shortened sleeve. A surgeon may be able to do this operation instead of a pneumonectomy to preserve more lung function.

With any of these operations, nearby lymph nodes are also removed to look for possible spread of the cancer.

The type of operation your doctor recommends depends on the size and location of the tumor and on how well your lungs are functioning. People whose lungs are healthier can withstand having more lung tissue removed. Doctors often prefer to do a more extensive operation (for example, a lobectomy instead of a segmentectomy) if a person’s lungs are healthy enough, as it may provide a better chance to cure the cancer.

When you wake up from surgery, you will have a tube (or tubes) coming out of your chest and attached to a special canister to allow excess fluid and air to drain out. The tube(s) will be removed once the fluid drainage and air leak subside. Generally, you will need to spend 5 to 7 days in the hospital after the surgery.

Video-assisted thoracic surgery: Some doctors now treat some early stage lung cancers near the outside of the lung with a procedure called video-assisted thoracic surgery (VATS), which requires smaller incisions than a thoracotomy.

During this operation, a thin, rigid tube with a tiny video camera on the end is placed through a small cut in the side of the chest to help the surgeon see inside the chest on a TV monitor. One or two other small cuts are created in the skin, and long instruments are passed through these cuts to do the same operation that would be done using an open approach (thoracotomy). One of the incisions is enlarged if a lobectomy or pneumonectomy is done to allow the specimen to be removed. Because usually only small incisions are needed, there is less pain after the surgery and a shorter hospital stay – usually 4 to 5 days.

Most experts recommend that only early stage tumors near the outside of the lung be treated this way. The cure rate after this surgery seems to be the same as with surgery done with a larger incision. But it is important that the surgeon doing this procedure is experienced, because it requires a great deal of technical skill.

Possible risks and side effects of lung surgery

Possible complications during and soon after surgery depend on the extent of the surgery and the person’s health beforehand. Serious complications can include excess bleeding, wound infections, and pneumonia. While it is rare, in some cases people may not survive the surgery, which is why surgery isn’t a good idea for everyone.

Surgery for lung cancer is a major operation, and recovering from the operation typically takes weeks to months. If the surgery is done through a thoracotomy, the surgeon must spread ribs to get to the lung, so the area near the incision will hurt for some time after surgery. Your activity will be limited for at least a month or two. People who have VATS instead of thoracotomy have less pain after surgery and tend to recover more quickly.

If your lungs are in good condition (other than the presence of the cancer) you can usually return to normal activities after some time if a lobe or even an entire lung has been removed. If you also have a non-cancerous lung disease such as emphysema or chronic bronchitis (which are common among heavy smokers), you may become short of breath with certain level of activity after surgery.

Surgery for lung cancers with limited spread to other organs

If the lung cancer has spread to the brain or adrenal gland and there is only one tumor, you may benefit from having the metastasis removed. This surgery should be considered only if the tumor in the lung can also be completely removed. Even then, not all lung cancer experts agree with this approach, especially if the tumor is in the adrenal gland.

For tumors in the brain, this is done by surgery through a hole in the skull (called a craniotomy). It should only be done if the tumor can be removed without damaging vital areas of the brain that control movement, sensation, and speech.
