Survival rates for esophagus cancer by stage

Survival rates are often used by doctors as a standard way of discussing a person's prognosis (outlook). Some patients 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. Whether or not you want to read about the survival statistics below for esophagus cancer is up to you.

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 longer than 5 years.

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

To get 5-year survival rates, doctors 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 esophagus cancer.

Survival rates are not readily available for each stage in the AJCC staging system for esophageal cancer. The survival rates below come from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database, and are based on patients who were diagnosed with esophageal cancer between 2001 and 2007. The SEER database does not divide survival rates by AJCC stage. Instead, this database divides cancers into 3 larger, summary stages:

• Localized means that the cancer is only growing in the esophagus. It includes AJCC stage I and some stage II tumors (such as those that are T1, T2, or T3, N0, M0). Stage 0 cancers are not included in these statistics.
• Regional means that the cancer has spread to nearby lymph nodes or tissues. This includes T4 tumors and cancers with lymph node spread (N1, N2, or N3).
• Distant means that the cancer has spread to organs or lymph nodes away from the tumor, and includes all M1 (stage IV) cancers.

These survival rates for esophageal cancer do not separate squamous cell carcinomas from adenocarcinomas, although adenocarcinomas are generally thought to have a slightly better prognosis (outlook) overall.

Survival rates are often based on previous outcomes of large numbers of people who had the disease, but they cannot predict what will happen to any particular person. Knowing the type and the stage of a person's cancer is important in estimating their outlook. But many other factors may also affect a person's outlook, such as how well the cancer responds to treatment and a person's overall health. Even when taking these other factors into account, survival rates are at best rough estimates. Your doctor can tell you how well the numbers above may apply to you.
