Chondrosarcomas in children and adolescents

Area of Science:

• Orthopedic Oncology
• Pediatric Bone Tumors
• Skeletal Radiology

Background:

• Chondrosarcomas in children and adolescents are rare, comprising less than 5% of all chondrosarcomas.
• Extremity chondrosarcomas in young patients are infrequently studied, with the pelvis and proximal femur being common sites.

Purpose of the Study:

• To review the diagnosis, treatment, and prognosis of chondrosarcomas in pediatric and adolescent populations.
• To highlight the importance of multidisciplinary collaboration in managing these rare bone tumors.

Main Methods:

• Review of existing literature on pediatric chondrosarcomas.
• Discussion of diagnostic challenges and the role of multidisciplinary teams.
• Analysis of treatment principles, including surgical excision and potential role of chemotherapy.

Main Results:

• Treatment principles for pediatric chondrosarcomas mirror adult management, with surgical resection being the cornerstone.
• Selected low-grade (Grade I) extremity chondrosarcomas may be managed with intralesional curettage.
• Chondrosarcomas are generally chemoresistant and radioresistant, except possibly mesenchymal subtypes.

Conclusions:

• Outcomes for chondrosarcomas in young patients are comparable to those in adults.
• Adequacy of surgical resection is the most critical factor influencing prognosis and recurrence rates.
• Multidisciplinary evaluation is essential for accurate diagnosis and optimal management of pediatric chondrosarcomas.
