Survival statistics for prostate cancer
Survival statistics for prostate cancer are very general estimates and must be interpreted very carefully. Because survival statistics are based on the experience of groups of men, they cannot be used to predict a particular man's chances of survival.
There are many different ways to measure and report cancer survival statistics. Your doctor can explain the statistics for prostate cancer and what they mean to you.
Net survival represents the probability 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 their cancer.
In Canada, the 5-year net survival for prostate cancer is 95%. This means that, on average, about 95% of men diagnosed with prostate cancer will survive for at least 5 years.
Relative survival looks at how likely people with cancer are to survive after their diagnosis compared to people in the general population who do not have cancer, but who share similar characteristics (such as age and sex).
Survival by stage
Survival varies with each stage of prostate cancer. The following factors can also affect survival for prostate cancer.
- Prostate cancer grows slowly. Many older men will die from diseases other than prostate cancer.
- Generally, the earlier prostate cancer is diagnosed and treated, the better the outcome.
- Sometimes prostate cancer is not found until it is at an advanced stage, which can make it more difficult to treat.
- Prostate cancer is very responsive to treatment.
- There are many effective treatments available for prostate cancer.
- Advanced, recurrent and hormone-resistant prostate cancers can be difficult to treat because these do not respond well to some cancer treatments.
- The grade of prostate cancer is also a strong predictor of survival.
Prostate cancer survival
|Stage||5-year relative survival|
stage I or stage II
stage III or stage IV without distant spread
stage IV with distant spread
UICC prognostic grouping of prostate cancer of the prostate is based on the stage, PSA level and the Gleason score of the prostate cancer. This is a more accurate grouping than stage grouping to assess prognosis.
Questions about survival
Talk to your doctor about your prognosis. A prognosis depends on many factors, including:
- your health history
- the type of cancer
- the stage
- certain characteristics of the cancer
- 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.
