There are many different types of treatment for non-small cell lung cancer. Treatment depends upon the stage of the cancer.

Surgery is the often the first line of treatment for patients with non-small cell lung cancer that has not spread beyond nearby lymph nodes. The surgeon may remove:

• One of the lobes of the lung (lobectomy)
• Only a small part of the lung (wedge or segment removal)
• The entire lung (pneumonectomy)

Some patients need chemotherapy. Chemotherapy uses drugs to kill cancer cells and stop new ones from growing.

• Chemotherapy alone is often used when the cancer has spread (stage IV).
• It may also be given before surgery or radiation to make those treatments more effective.
• It may be given after surgery (called adjuvant therapy) to kill any remaining microscopic areas of cancer.

Radiation therapy uses powerful x-rays or other forms of radiation to kill cancer cells. Radiation therapy can be used with chemotherapy if surgery is not possible.

The following treatments are mostly used to relieve symptoms caused by NSCLC:

• Laser therapy - a small beam of light burns and kills cancer cells
• Photodynamic therapy - uses a light to activate a drug in the body, which kills cancer cells

The outlook varies widely. Most often, NSCLC develops slowly and causes few or no symptoms until very late stages. However, in some cases, it can be extremely agressive and cause rapid death. The cancer may spread to other parts of the body, including the bone, liver, small intestine, and brain.

Chemotherapy has been shown to prolong the life and improve the quality of life in some patients with stage IV NSCLC.

Cure rates are related to the stage of disease and whether you are able to have surgery.

• Stage I and II cancer can be cured with surgery, sometimes in more than 50% of cases.
• Stage III tumors can be cured in some cases, but cure rates are much lower than earlier stage NSCLC
• Patients with stage IV disease are almost never cured, and the goals of therapy are to extend and improve the quality of their life.

• Spread of disease beyond the lung
• Side effects of surgery, chemotherapy, or radiation therapy
