Long-term Outcomes for Children with Ewing Sarcoma
For children with metastatic disease, the five-year survival rate is 20 to 30 percent. Children with Ewing sarcoma that comes back after initial treatment (called "relapsed" or "recurrent" disease) have a poor prognosis.
Often, the first sign of a soft-tissue sarcoma is a painless lump or mass. Along with the lump, swelling may occur in nearby tissues. Sarcoma lumps can be confused with noncancerous masses, most commonly lipomas, which are made of fat cells, but there are some differences.
A biopsy is needed to confirm a Ewing sarcoma diagnosis. Your healthcare team uses this information to make a treatment plan.
Ewing sarcoma is a rare type of bone or soft tissue cancer that primarily affects children. With treatment, doctors can often cure the disease. A person's survival rate is also much higher if the tumor has not spread beyond where it started.
Ewing sarcoma most often occurs in children between the ages of 10 and 20. More males are affected than females. This type of cancer is uncommon in African-American, African and Chinese children.
The annual incidence of Ewing sarcoma (ES) in the United States is 2.93 per million children (2). Since 1970, the survival of patients with ES has increased substantially. Presently, the 5-year overall survival rate for localized ES is about 75% (3).
Although most lumps and bumps are not sarcomas, it is crucial to be aware of red flag signs indicating a need for further investigation, such as lumps that are growing, changing, larger than a golf ball, deep (reaching the fascia), increasing in size, painful, or recurring after removal.
Delays between tumor recognition by a patient to diagnosis were between 1 and 3 years in most cases. However, in three cases of synovial sarcoma, it took more than 10 years to reach a diagnosis, and in another case of synovial sarcoma, it took more than 5 years.
A soft tissue sarcoma lump may often be mistaken by medical practitioners for a hematoma (bad bruise), abscess (inflamed bump), pulled muscle, lipoma or something else that is benign. Sarcoma in general can be difficult to diagnose, and X-rays or a standard ultrasound does not provide a definitive diagnosis.
Common symptoms include: Bone pain that comes and goes and seems to get worse at night. Swelling in the tissue around bones. People may complain about feeling stiff or noticing it hurts when they touch some areas on their bones or next to their bones.
