Uterine sarcoma

Survival statistics can be difficult to read, especially soon after a cancer diagnosis. These numbers describe what happened to groups of people in the past. They cannot predict exactly what will happen to you.

Your outlook depends on many things, including the type and stage of uterine sarcoma, your overall health, the treatments available to you, and how well the treatment works to kill the cancer cells. Your cancer care team can help you understand what these numbers may mean for your situation.

5-year relative survival rates

A five-year relative survival rate compares people who have uterine sarcoma with people in the general population. The U.S. data is based on people diagnosed from 2015 through 2021.

These data group cancer by how far it has spread:

• Localized. The cancer is only in the uterus.
• Regional. The cancer has spread to nearby areas.
• Distant. The cancer has spread to distant parts of the body.
• All stages combined. This includes data from all three groups.

For uterine leiomyosarcoma, five-year relative survival is:

• Localized. 61%.
• Regional. 28%.
• Distant. 13%.
• All stages combined. 38%.

For low-grade endometrial stromal sarcoma, five-year relative survival is:

• Localized: 98%.
• Regional: 88%.
• Distant: 78%.
• All stages combined: 93%.

For undifferentiated uterine sarcoma, five-year relative survival is:

• Localized: 73%.
• Regional: 38%.
• Distant: 17%.
• All stages combined: 46%.

High-grade endometrial stromal sarcoma tends to have an outlook more like undifferentiated uterine sarcoma than low-grade endometrial stromal sarcoma.

What about uterine adenosarcoma?

Uterine adenosarcoma is one type of uterine sarcoma. The U.S. data does not give a separate survival rate for adenosarcoma.

What survival rates can and can't tell you

Survival rates describe what happened to groups of people who were diagnosed and treated in the past. They can give you a general idea of what to expect, but they cannot predict exactly what will happen to you. Treatments also continue to change, so outcomes today may be different.
