Survival statistics for liver cancer
Survival statistics for liver 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 liver 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 liver cancer is 19%. This means that, on average, about 19% of people diagnosed with liver cancer will survive for at least 5 years.
Survival by stage
Survival varies with each stage of liver cancer. The following factors can also affect survival for liver cancer.
- Liver cancer is not often found until it is at an advanced stage, when it can no longer be removed by surgery.
- Having liver disease, such as cirrhosis, can affect survival.
- Survival by stage of liver cancer is usually reported as a median survival. Median survival is the period of time (usually months or years) after diagnosis or treatment at which half of the people with a given disease will live longer and the other half will live less than this amount of time.
There are no specific Canadian statistics available for the median survival of different stages of liver cancer. The following information comes from a variety of sources and may include statistics from other countries.
0 or A
Median 5-year survival is 40%–70%, if treated with liver resection, radiofrequency ablation, or RFA, (for tumours 2 cm or less) or liver transplant.
Median survival is 16 months. It may increase to 20 months with transarterial chemoembolization (TACE).
Median survival is 8 months. It may increase to 11 months with targeted therapy.
Median survival is 3 months.
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.
It was very important that the fundraiser be in honour of my uncle, because it’s a great way to show our support for him.
Investing to reduce cancer burden
Last year CCS funded $40 million in cancer research, thanks to our donors. Discover how you can help reduce the burden of cancer.
