Survival statistics for parathyroid cancer

Survival statistics for parathyroid 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 parathyroid cancer and what they mean to you.

Relative survival

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).

In Canada, a separate 5-year relative survival statistic is not reported for parathyroid cancer. But the United States has reported survival statistics for parathyroid cancer. These will likely have similar outcomes as in Canada. According to US statistics, the 5-year relative survival is 93%. This means that, on average, people diagnosed with parathyroid cancer are 93% as likely to live at least 5 years after their diagnosis as people in the general population.

The 10-year US relative survival is 82%.

In other 5-year statistics for Canada, parathyroid is included in a group called other endocrine cancers. Other endocrine cancers include cancers similar to parathyroid cancer that are grouped and reported together. This statistic does not necessarily reflect the actual survival for the individual cancers within the group. The 5-year relative survival for other endocrine cancers is 63%.

Survival by stage

Survival of parathyroid cancer varies with each stage (where the cancer is in the body). There are no specific Canadian statistics available for the different stages of parathyroid cancer. The following survival statistics by stage come from the US.

Questions about survival

Talk to your doctor about your prognosis. A prognosis depends on many factors, including:

  • your health history
  • the stage
  • the calcium level in your blood and how well it is controlled
  • if the cancer can be completely removed with surgery
  • 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.
