Ewing's Sarcoma is a malignant round-cell bone tumor which usually occurs
in the arm or the leg. It most commonly affects individuals between the ages
of 10 and 20 years.
Symptoms
Ewing's Sarcoma appears as a tumor which can be felt if not seen, and is
usually painful to the touch. Most of these tumors develop in the bones of
the extremities, but any bone may be affected. The tumor tends to be
extensive, sometimes involving the entire shaft of a long bone. It most
commonly occurs in the bone that extends from the hip to the knee (femur) or
from the shoulder to the elbow (humerus). Sometimes it occurs in the
pelvis. Pain tends to increase with the duration of the tumor. There may be
tenderness and swelling in the area, and often intermittent pain that worsens
during the night. The skin overlying the tumor may be warm and superficial
blood vessels may be prominent. The affected individual may also develop a
fever and anemia. If untreated the tumor has a tendency to spread to the
lungs, lymph nodes or the skull.
Causes
Ewing's Sarcoma is usually inherited as an autosomal dominant trait. Human
traits, including the classic genetic diseases, are the product of the
interaction of two genes, one received from the father and one from the
mother. In dominant disorders a single copy of the disease gene (received
from either the mother or father) will be expressed "dominating" the other
normal gene and resulting in appearance of the disease. The risk of
transmitting the disorder from the affected parent to offspring is fifty
percent for each pregnancy regardless of the sex of the resulting child.
Affected Population
Ewing's Sarcoma most commonly occurs in young males between the ages of 10
and 20. There are approximately 200 different types of cancer, and bone
cancers comprise some of the rarest forms.
Related Disorders
Symptoms of the following disorders can be similar to those of Ewing's
Sarcoma. Comparisons may be useful for a differential diagnosis:
Osteosarcoma is one of the most common types of primary bone tumor. It
is highly malignant, and commonly spreads to the lungs. It is most common in
persons aged 10 to 20 years although it can occur at any age. Most tumors
are located in the knee region, but can be found in any bone. A painful mass
is the most usual symptom.
Malignant Lymphoma of the bone is a small round-cell tumor that most
frequently affects adults in their 40's and 50's. It may arise in any bone.
Pain and swelling are the most common symptoms. The cancer may spread to
other soft tissue or bone. When Malignant Lymphoma occurs in the bone
without evidence of disease elsewhere, the outlook is better than for any
other primary malignant bone tumor. A combination of radiation and
chemotherapy is standard treatment.
Chondrosarcoma is a malignant tumor of the cartilage. Depending upon the
severity of the tumor, it may grow slowly or rapidly. Rapid growing tumors
usually spread. Chondrosarcomas have the ability to seed or implant in
surrounding soft tissues. Treatment is usually by surgical removal, and care
must be given during surgery to avoid entry into the tumor and spillage of
the contents onto the soft tissues of the wound.
Osteochondroma is the most common benign (noncancerous) bone tumor. It
occurs most often in persons aged 10 to 20. An Osteochondroma may occur as a
single or multiple tumor. A strong familial tendency toward multiple
Osteochondromas may indicate a genetic predisposition to these tumors.
Therapies: Standard
Treatment of Ewing's Sarcoma consists of various combinations of surgery,
chemotherapy and radiation therapy. Approximately 50% of patients are cured
with appropriate treatment.
Therapies: Investigational
