Survival rates tell you what portion of people with the same type and stage of cancer are still alive a certain length of time (typically 5 years) after they were diagnosed. These numbers can’t inform you how long you will live, but they might assist offer you a better understanding about how likely it is that your treatment will be successful.

What is a 5-year survival rate?

Statistics on the outlook for people with a certain type and stage of cancer are frequently given as 5-year survival rates, but many people live longer– typically a lot longer– than 5 years. The 5-year survival rate is the portion of people who live a minimum of 5 years after being identified with cancer. For instance, a 5-year survival rate of 90% implies that an approximated 90 out of 100 people who have that cancer are still alive 5 years after being detected.

Relative survival rates are a more precise way to approximate the effect of cancer on survival. These rates compare people with stomach cancer to people in the general population. For instance, if the 5-year relative survival rate for a specific type and stage of cancer is 90%, it indicates that people who have that cancer are, on average, about 90% as likely as people who do not have that cancer to live for a minimum of 5 years after being identified.

Stomach cancer survival rates, by stage

These survival rates originate from the National Cancer Database (NCDB) and were released in 2017 in the 8th edition of the AJCC Staging Manual. They are based on people detected with stomach cancer and treated with surgery in between 2004 and 2008. Survival rates for patients not treated with surgery are most likely to be lower. It is also crucial to keep in mind that these are observed survival rates. People with cancer can pass away of other things, and these rates do not take that into account.

The 5-year survival rates by stage for stomach cancer treated with surgery are as follows:

Stage 5 year
observed
survival
Stage IA 94%
Stage IB 88%
Stage IIA 82%
Stage IIB 68%
Stage IIIA 54%
Stage IIIB 36%
Stage IIIC 18%

The total 5-year relative survival rate of all people with stomach cancer in the United States has to do with 31%. The 5-year relative survival rate compares the observed survival of people with stomach cancer to that expected for people without stomach cancer. Because some people may die from other causes, this is a much better method to see the impact of cancer on survival.

This survival rate has actually enhanced gradually over the last 30 years. One reason the general survival rate is poor in the United States is that many stomach cancers are detected at an innovative rather than an early stage. The stage of the cancer has a major impact on a patient’s prognosis (outlook for survival).
