Your long-term outcome (prognosis) depends on the type and stage of
your lung cancer. The 5-year survival rate means the percentage of people who
are still alive 5 years or longer after their cancer was discovered. It is
important to remember that these are only averages. Everyone's case is
different, and these numbers do not necessarily show what will happen to you.
The overall 5-year survival rate of 15% is low because lung cancer is often not
detected until it has reached an advanced stage.1
Non–small cell cancer survival rates
Non–small cell lung cancer generally grows and spreads more slowly
than small cell lung cancer. The survival rates decrease as the
stage of cancer involves
lymph nodes or other body organs. In
general, survival rates are as shown:2
Non-small cell lung cancer treatment and
survival rates| Stage | Treatment | Survival rate |
|---|
I | Surgery followed by
chemotherapy | 5-year, 60% to 70% |
II | Surgery followed by chemotherapy and perhaps
radiation | 5-year, 40% to 50% |
IIIA (resectable) | Surgery followed by radiation, and may have
chemotherapy before or after surgery | 5-year, 15% to 30% |
IIIA (unresectable) or IIIB | Chemotherapy with radiation at the same time, or chemotherapy
followed by radiation | 5-year, 10% to 20% |
IIIB (pleural effusion) or IV | Chemotherapy with 2 medications for 3 or 4 treatment
cycles | 8 to 10 months, 1-year, 30% to 35%, 2-year 10% to
15% |
| Surgery for lung tumor and single brain tumor | 5-year, 10% to 15% |
Recurrent non–small cell lung cancer survival
rates
Your prognosis with non–small cell lung cancer that comes back
(recurrent cancer) depends on the stage of your lung cancer when it was first
diagnosed, as well as the stage of your cancer when it recurs in the lungs.
Treatment for recurrent cancer is based on the stage of the cancer at the time
it comes back.
Small cell cancer survival rates
Small cell lung cancer is less common than non–small cell cancer
but grows very rapidly in most cases and is more likely to spread to other
organs. Small cell lung cancer is
staged as limited or extensive. Limited small cell
cancer is found only in one lung and in nearby
lymph nodes. Extensive small cell cancer has spread
(metastasized) outside of the lung to other tissues in the chest or to other
parts of the body. Only about one-third of people with small cell cancer have
limited disease at the time they are diagnosed, while two-thirds have extensive
disease.3, 4 In
general, survival rates are as shown:2
Small cell lung cancer treatment and survival
rates| Stage | Treatment | Survival rate |
|---|
Limited | Chemotherapy with radiation at the same time | 5-year: 15% to 25% |
Extensive | Chemotherapy | 5-year: up to 5% |
Recurrent small cell lung cancer survival
rates
People whose lung cancer returns after it is treated have a poor
prognosis, with most people living only 2 to 3 months after they are diagnosed
with recurrent disease.
