Stage 0
At this stage do not require chemotherapy or radiotherapy. Surgery may completely remove the cancer. The type of surgery is a segmentectomy, ie the removal of a lung wedge.

Stage I
Segmentectomy is generally used for smaller tumors or for patients with worse physical condition, or lobectomy to remove the tumor.

The effectiveness of adjuvant chemotherapy, is being tested in clinical trials. Although micrometastases is useful for those that have not been identified and have not been removed by surgery.

If the tumor is at the edge of the lung tissue probably not have removed all the cancer cells, so radiation therapy is recommended.

Radiation therapy can be used as primary treatment if the patient, general condition, can not undergo surgery. The survival rate after five years in this stage is 65%.

Stage II
Used surgery: segmentectomy or lobectomy.

Radiation therapy can be used after surgery to ensure that it is not any cancer cells. It can also be used as primary therapy in those patients who can not be operated on by health problems. Chemotherapy may be used after surgery or radiotherapy.

The survival rate for patients who are in this stage of cancer is 40%.

Stage IIIA
Treatment at this stage will depend on where the tumor is located in the lung and whether lymph nodes are affected.

Chemotherapy is often used before surgery to shrink the tumor, to make it easier to complete removal.

When surgery can not be used to remove the tumor, radiation therapy. It is sometimes used brachytherapy which involves passing a laser through a bronchoscope to destroy part of the cancer within the trachea.

Survival rates range from 10% to 20%, although certain patients such as those with no cancer spread to lymph nodes have a better prognosis.

Stage IIIB
Because at this stage the cancer is widespread, surgery is not effective. Chemotherapy may be used together with radiotherapy. Or each one separately.

The survival rate is between 10% and 20% in those patients who enjoy a good health condition and may undergo a combination of both treatments. Those who can not, its index is 5%.

Stage IV
The aim of treatment at this stage is to alleviate the symptoms of the disease. It is not intended as a cure the cancer has spread to distant sites.

Chemotherapy or radiotherapy is used to reduce symptoms such as bone pain, symptoms due to nervous system, etc..
