What is the survival rate of leiomyosarcoma?

The five-year relative survival rate for leiomyosarcoma patients is about 63 percent for Stage I cancer confined to the uterus, and about 36 percent for Stage II and III patients, states the American Cancer Society. The rate is approximately 14 percent when the cancer has spread beyond the lymph nodes.

To determine the five-year relative survival rates, doctors compare the numbers of people who are cancer survivors with the numbers of people who have survived without the cancer. This method more effectively shows the impact of a specific type and stage of cancer on a patient's survival, since it considers causes of death other than cancer, notes the American Cancer Society.
