Stages

Once uterine sarcoma has been diagnosed, doctors perform tests to determine the stage of the cancer. Staging is the process of determining:

  • The grade of your cancer (how abnormal the cells look and how likely the cancer is to grow and spread)

  • Whether (and how deeply) it has invaded other tissues of your uterus

  • Whether it has spread outside your uterus

Doctors use a cancer’s stage as a key factor in making treatment recommendations and estimating a patient’s chance for recovery. For uterine sarcoma, staging is typically done at the time of surgery, which means you and your health care team will probably need to wait until after surgery to make some of your treatment decisions.

The most common staging system for gynecological cancers is the International Federation of Gynecology and Obstetrics (FIGO) 2010 system. This is the system that gynecologic oncologists at Seattle Cancer Care Alliance use.

  • Stage I: Cancer is only in the uterus. It has not spread to any lymph nodes or distant parts of the body.

  • Stage II: Cancer has spread beyond the uterus but not outside the pelvic area. It has not spread to any lymph nodes or distant parts of the body.

  • Stage III: Cancer has spread to the abdomen but not to any lymph nodes or distant parts of the body; or cancer has spread to lymph nodes near the uterus but not to the bladder, rectum, or distant parts of the body.

  • Stage IV: Cancer has spread to the bladder or rectum, lymph nodes outside the pelvis, or organs outside the pelvis, such as the lungs, liver, or bones.
