Sarcoma

Bone sarcomas

Osteosarcoma

• Most common type of bone cancer in children and teenagers
• Typically develops in areas of rapid bone growth such as arms and legs
• Peak occurrence during teenage growth spurts
• Common locations: knee, upper arm, and hip bones

Ewing’s sarcoma

• An aggressive bone cancer that can also develop in soft tissues
• Often affects the pelvis, chest wall and long bones
• Most common in teenagers aged 12-18
• May present with persistent pain and swelling

Soft tissue sarcomas

Rhabdomyosarcoma

• Most common soft tissue sarcoma in children under 10
• Originates in the muscle tissue
• Can occur anywhere in the body
• Often found in the head and neck region, bladder, or arms and legs

Liposarcoma

• Develops from fat cells
• More common in adults but can affect young people
• Usually occurs in limbs or abdomen
• May present as a painless, growing mass

Treatment typically involves a combination of

Surgery

• Primary treatment for most sarcomas
• Aims to remove the tumour and surrounding margin of healthy tissue
• May include limb-sparing techniques or reconstruction

Chemotherapy

• Often used before surgery (neoadjuvant) to shrink tumours
• Given after surgery (adjuvant) to kill remaining cancer cells
• Protocols vary by sarcoma type and stage

Radiation therapy

• May be used before or after surgery
• Helps control local tumour growth
• Precisely targeted to protect healthy tissue
• Sometimes used instead of surgery in sensitive locations

Sarcomas pose unique challenges for healthcare providers and patients

Early detection difficulties

• Rarity makes diagnosis challenging and clinical expertise may not be readily available
• Symptoms may mimic other conditions

Aggressive growth

• Sarcomas often grow quickly, this can complicate treatment planning and impact prognosis

Complex treatment planning

• Each subtype requires a different approach, coordinated multidisciplinary care is needed

Treatment resistance

• Some sarcomas don’t respond well to standard treatments
• Research for new therapies is critical

Limited data

• Historically there has been a lack of comprehensive registries for clinicians and scientists
• Limited understanding of incidence and prevalence

Seek immediate medical attention if your child develops

• Persistent pain in bones or muscles, especially pain that wakes them at night, doesn’t improve with rest or gets progressively worse
• Unexplained swelling or lumps, particularly if they grow in size, are firm to touch, appear deep under the skin

Other warning signs

• Night sweats or fever
• Unexplained weight loss
• Unusual fatigue
• Bone fractures without significant injury
