Survival statistics for non–small cell lung cancer
Survival statistics for non–small cell lung cancer are very general estimates and must be interpreted very carefully. Because these statistics are based on the experience of groups of people, they cannot be used to predict a particular person’s chances of survival.
There are many different ways to measure and report cancer survival statistics. Your doctor can explain the statistics for non–small cell lung cancer and what they mean to you.
Net survival
Net survival represents the probability (chance) of surviving cancer in the absence of other causes of death. It is used to give an estimate of the percentage of people who will survive cancer.
In Canada, the 5-year net survival for lung cancer is 22%. This means that, on average, about 22% of people diagnosed with lung cancer will live for at least 5 years.This net survival includes both non–small cell and small cell lung cancer, there are no separate net survival statistics for each type.
Survival varies with each stage of lung cancer. Generally, the earlier lung cancer is diagnosed and treated, the better the outcome.
Survival for non–small cell lung cancer
In Canada, survival by stage for lung cancer is reported as 5-year net survival.
| Stage | 5-year net survival |
|---|---|
| 1 | 62% |
| 2 | 39% |
| 3 | 16% |
| 4 | 3% |
| stage not known | 14% |
Questions about survival
Talk to your doctor about your prognosis. A prognosis depends on many factors, including:
- your health history
- the type of lung cancer
- the stage
- certain aspects of the cancer, such as genetic changes to the cancer cells
- the treatments chosen
- how the cancer responds to treatment
Only a doctor familiar with these factors can put all of this information together with survival statistics to arrive at a prognosis.
