Sarcoma

Sarcoma is a rare type of cancer that develops in the body's bones or soft tissues, including muscles, fat, nerves, blood vessels, and connective tissues. In children, the most common types are Osteosarcoma, Ewing Sarcoma, and Rhabdomyosarcoma. Early diagnosis and specialized multidisciplinary care are essential for achieving the best possible outcomes.

Common signs and symptoms of Sarcoma include:

• Persistent pain in a bone or soft tissue
• Swelling or a noticeable lump
• Limited movement of a joint or limb
• Bone fractures with minimal injury
• Fatigue or weakness
• Fever
• Unexplained weight loss
• Difficulty walking or limping
• Pain that worsens at night or during activity

The exact cause of Sarcoma is not fully understood. It develops when genetic mutations cause bone or soft tissue cells to grow uncontrollably. Most childhood sarcomas occur without a known cause, although certain inherited genetic conditions may increase the risk.

Factors that may increase the risk of developing Sarcoma include:

• Certain inherited genetic syndromes
• Previous radiation therapy
• Rare inherited cancer predisposition disorders
• Rapid bone growth during adolescence (especially Osteosarcoma)
• Family history of certain cancers

Most children diagnosed with Sarcoma have no identifiable risk factors.

Diagnosis involves a combination of clinical evaluation, imaging, and laboratory investigations.

Common diagnostic tests include:

• Physical examination
• X-rays
• Ultrasound (for soft tissue masses)
• MRI Scan
• CT Scan
• PET-CT Scan
• Bone Scan (when indicated)
• Biopsy
• Blood tests
• Genetic and molecular testing

Treatment depends on the type, location, stage, and biological characteristics of the Sarcoma.

Treatment options may include:

• Surgery to remove the tumor
• Chemotherapy
• Radiation therapy
• Limb-salvage surgery (when possible)
• Targeted therapy (selected cases)
• Precision medicine based on molecular profiling
• Rehabilitation and long-term follow-up care

Every child receives an individualized treatment plan developed by a multidisciplinary pediatric oncology team.

The prognosis for children with Sarcoma depends on the type of Sarcoma, tumor size, location, stage at diagnosis, and response to treatment. Advances in surgery, chemotherapy, radiation therapy, and precision medicine have significantly improved survival rates, allowing many children to achieve long-term remission and maintain a good quality of life.
