Lung Cancer Treatment
Lung Cancer Treatment Options
There are different types of treatment for patients with non-small cell lung cancer ranging from lung cancer chemotherapy to lung cancer surgery as well as others.
* Six types of standard treatment are used:
o Radiation therapy
o Laser therapy
o Photodynamic therapy (PDT)
o Watchful waiting
* New types of treatment are being tested in clinical trials.
o Biologic therapy
o New combination’s
* Patients may want to think about taking part in a clinical trial.
* Patients can enter clinical trials before, during, or after starting their cancer treatment.
* Follow-up tests may be needed.
There are different types of treatment for patients with non-small cell lung cancer.
Different types of treatments are available for patients with non-small cell lung cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Six types of standard treatment are used:
Four types of surgery are used:
* Wedge resection: Surgery to remove a tumor and some of the normal tissue around it. When a slightly larger amount of tissue is taken, it is called a segmental resection.
Wedge resection of the lung; shows trachea and lungs with cancer in a lung lobe. The removed lung tissue with the cancer and small amount of healthy tissue around it is shown next to the lung lobe it was removed from.
Wedge resection of the lung. Part of the lung lobe containing the cancer and a small amount of healthy tissue around it is removed.
* Lobectomy: Surgery to remove a whole lobe (section) of the lung.
Lobectomy; drawing shows lobes of both lungs, trachea, bronchi, bronchioles, and lymph nodes. Cancer is shown in one lobe. The removed lobe is shown next to the lung from which it was removed.
Lobectomy. A lobe of the lung is removed.
* Pneumonectomy: Surgery to remove one whole lung.
Pneumonectomy; drawing shows the trachea, lymph nodes, and lungs, with cancer in one lung. The removed lung with the cancer is shown.
Pneumonectomy. The whole lung is removed.
* Sleeve resection: Surgery to remove part of the bronchus.
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.
Radiosurgery is a method of delivering radiation directly to the tumor with little damage to healthy tissue. It does not involve surgery and may be used to treat certain tumors in patients who cannot have surgery.
The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Laser therapy is a cancer treatment that uses a laser beam (a narrow beam of intense light) to kill cancer cells.
Photodynamic therapy (PDT)
Photodynamic therapy (PDT) is a cancer treatment that uses a drug and a certain type of laser light to kill cancer cells. A drug that is not active until it is exposed to light is injected into a vein. The drug collects more in cancer cells than in normal cells. Fiberoptic tubes are then used to carry the laser light to the cancer cells, where the drug becomes active and kills the cells. Photodynamic therapy causes little damage to healthy tissue. It is used mainly to treat tumors on or just under the skin or in the lining of internal organs.
Watchful waiting is closely monitoring a patient’s condition without giving any treatment until symptoms appear or change. This may be done in certain rare cases of non-small cell lung cancer.
New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.
Chemoprevention is the use of drugs, vitamins, or other substances to reduce the risk of developing cancer or to reduce the risk cancer will recur (come back).
Biologic therapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
New combinations of treatments are being studied in clinical trials.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today’s standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI’s clinical trials database.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
