Survival Rates for Oral Cavity and Oropharyngeal Cancer by Stage

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. If you don’t want to read about the survival statistics below for oral cavity and oropharyngeal cancer, stop reading here and skip to the next section.

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 of these people live much longer than 5 years.

Five-year relative survival rates, such as the numbers below, assume that some people will die of other causes and compares the observed survival of people with cancer with that expected for people without cancer. This is a more accurate way to describe the impact that a particular type and stage of cancer may have on survival.

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 these cancers.

Survival rates are often based on previous outcomes of large numbers of people who had the disease, but they cannot predict what will happen in any individual’s case. Many other factors may affect a person’s outlook, such as the patient’s age and health, the treatment received, and how well the cancer responds to treatment. Your doctor can tell you how the numbers below may apply to you, because they are familiar with the aspects of your particular situation.

The following survival statistics come from the National Cancer Institute’s SEER program. They are based on large numbers of patients diagnosed between 2000 and 2014. SEER doesn’t provide recent statistics by AJCC stage. Instead, cancers are divided into the summary stages:

• Local: the cancer is only in the area where it started. This includes stages I and II, as well as some stage III cancers that haven’t spread to any lymph nodes.
• Regional: the cancer has spread to nearby tissues and/or lymph nodes. This includes some stage III cancers, as well as stage IV cancers that haven’t spread to distant sites
• Distant: the cancer has spread to distant sites

Also, these statistics are based on the stage of the cancer when it was first diagnosed. They do not apply to cancers that have come back or spread, for example.
