Survival rates are often used by doctors as a standard way of discussing a person's prognosis (outlook). Some patients with cancer may want to know the survival statistics for people in similar situations, while others may not find the numbers helpful, or may even not want to know them.
The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed. Of course, many people live much longer than 5 years (and many are cured).
Five-year relative survival rates compare the survival of people with the cancer to the survival for people without the cancer. This is a way to take into account deaths from causes other than cancer. The 5-year relative survival rate is a better way to describe the impact of a particular type and stage of cancer on survival.
In order to get 5-year survival rates, doctors have to look at people who were treated at least 5 years ago. Improvements in treatment since then may result in a more favorable outlook for people now being diagnosed with uterine sarcoma.
