Question
How to diagnose and treat pediatric osteosarcoma?
Answer
Patients should undergo surgical exploration and pathological examination to confirm the condition. Possible diagnoses include proliferative osteitis, osteomyelitis, fibrous dysplasia, bone metastasis tumors, and primary osteosarcoma. Differential diagnosis should be conducted and a treatment plan should be determined as early as possible. The surgical process may include the removal of the left thigh femur lesion, sterilization, and fixation with bone grafting and steel plates. Patients should have regular follow-ups after treatment, and attention should be paid to rest and nutrition to reduce the chance of recurrence.
