Survival rates

Survival rates can give a general idea of how people with metastatic stomach cancer have done in the past. But they cannot predict exactly what will happen to any one person.

Other factors can affect expected outcomes. These include overall health, how widely the cancer has spread and how well it responds to treatment.

For adults with distant stomach cancer, National Cancer Institute data shows the following survival rates. These rates are based on how long people are alive after their cancer is diagnosed:

Time after diagnosis Survival rate
1 year 31%
5 years 7%
10 years 5%

What you can do

Some factors that affect survival cannot be changed. These include how widely the cancer has spread and certain features of the cancer itself.

Other steps may help you manage treatment and maintain your quality of life:

  • Work with your healthcare team to understand your treatment options and whether other treatments or clinical trials may be available.
  • Tell your healthcare team about side effects and new or worsening symptoms. Managing these issues may make treatment easier to tolerate.
  • Pay attention to nutrition. Weight loss and malnutrition are common concerns in advanced cancer and can affect strength, quality of life and the ability to tolerate treatment. A dietitian with experience in cancer care can help you find ways to get enough calories, protein and nutrients.

Treatments continue to improve

Survival statistics are based on people treated in the past. It takes several years to collect survival data, so the most recent statistics may not fully reflect the effects of newer treatments.

Treatment for metastatic stomach cancer has changed in recent years. Immunotherapy and targeted medicines have expanded treatment options for some people, and research continues to look for better ways to control the disease.
