Stage 4 lung cancer usually has a poor prognosis. Life expectancy for lung cancer is given as five-year survival rates, or how many people will be alive five years after diagnosis. Five-year survival rates for metastatic non-small cell lung cancer are 6%, while five-year survival rates for metastatic small cell lung cancer are 3%. Stage 4 lung cancer (also called metastatic lung cancer) is lung cancer that has spread (metastasized) to other parts of the body outside the lungs, such as the brain, bones, and liver. Life expectancy for lung cancer is often expressed in 5-year survival rates, that is, how many people will be alive 5 years after diagnosis. Stage 4 lung cancer usually has a poor prognosis.
One study found that depending on the stage of the metastases (spread) the average survival time following diagnosis of stage 4 lung cancer ranged from 6.3 months to 11.4 months. There are a number of factors that can impact life expectancy with stage 4 lung cancer. Factors associated with a less favorable outcome include:
What Are Symptoms of Stage 4 Lung Cancer?Early in the disease, people with lung cancer may not have symptoms. When the symptoms occur, they may include:
Symptoms of stage 4 lung cancer that has spread to other parts of the body may include:
What Is the Treatment for Stage 4 Lung Cancer?Stage 4 lung cancers are widespread and very hard to treat and cure. Any of the treatments listed below may help patients live longer, but they are unlikely to cure the disease at this late stage. Treatment for lung cancer depends on the stage, and treatments for stage 4 lung cancer may include:
QUESTIONLung cancer is a disease in which lung cells grow abnormally in an uncontrolled way.

Other serious liver complications can also lead to HE. The condition causes reduced brain function because the liver can no longer filter out toxins in the blood.
How long can you live with liver and lung metastasis?Metastasis to the bone or pleura is not imminently life threatening; however, metastasis to the liver, lung, or brain considerably reduces the patient's life expectancy. A patient with metastasis to the liver and lung has a median life expectancy of less than six months.
How long can a person live with lung and liver cancer?The relative 5-year survival rate for liver cancer that has spread to lymph nodes or other nearby tissues is 11 percent , according to the American Cancer Society. When the cancer has spread to the lungs, bones, or other organs, the relative 5-year survival rate is 2 percent .
How long can you live with metastatic small cell lung cancer?Limited stage small cell lung cancer has a median survival of 12 to 16 months, with treatment. Extensive stage small cell lung cancer has a median survival of 7 to 11 months, with treatment.
