Ewing Family of Tumors
The Ewing family of tumors represents a group of aggressive cancers that primarily affect the bones or soft tissues.
These tumors most often occur in children and young adults, commonly involving the pelvis, femur, or chest wall.
Treatment typically combines chemotherapy, surgery, and sometimes radiation therapy, aiming to eradicate disease and preserve function.
Overview And Clinical Background
Rare pediatric bone and soft tissue tumors
Ewing tumors originate from primitive neuroectodermal cells and belong to a family including classic Ewing sarcoma and Askin tumor.
They are characterized by specific chromosomal translocations involving the EWS gene.
- Origin Derived from neuroectodermal cells, often in long bones or pelvis.
- Genetic hallmark EWSR1-FLI1 fusion gene in most cases.
- Epidemiology Primarily affects adolescents and young adults, more common in males.
Symptoms, Signs And Presentation
Symptoms vary depending on tumor location but often mimic benign conditions.
Persistent pain and swelling are key clues.
- Bone pain Persistent, deep pain, often worse at night or with activity.
- Swelling or mass Localised swelling, warmth, or palpable lump.
- Systemic signs Fever, fatigue, or weight loss in advanced disease.
Diagnosis Methods And Investigations
Imaging and biopsy confirmation
Diagnosis involves imaging to define extent and biopsy to confirm histology and genetics.
Staging scans assess for lung or bone metastases.
- X-ray and MRI Shows bone destruction with soft tissue extension.
- Biopsy Confirms diagnosis and identifies EWS translocation.
- Staging CT chest and bone scan to check metastatic spread.
Treatment Options And Surgical Techniques
Treatment is multimodal, combining chemotherapy, surgery, and radiation therapy.
The goal is cure with limb preservation when possible.
- Chemotherapy Used before and after surgery to shrink and eliminate microscopic disease.
- Surgery Wide local resection with limb-sparing techniques when feasible.
- Radiation therapy For unresectable or margin-positive tumors.
Recovery, Risks And Prognosis
Prognosis depends on stage and response to therapy.
Localized disease has high survival rates with modern protocols; metastatic disease remains challenging but treatable.
