1. Pain
Initially intermittent and dull, later progressing to persistent aching pain; nocturnal worsening is a characteristic feature.
2. Mass
A firm mass at the affected site that progressively enlarges, with indistinct borders; overlying skin temperature may be increased.
3. Functional impairment
Restricted joint motion, muscle atrophy and weakness, limping, and reduced weight-bearing capacity.
4. Pathological fracture
Fracture occurring after minimal trauma or without clear injury, often with poor healing and accelerated tumor dissemination.
5. Systemic symptoms
In advanced disease, weight loss, fatigue, anemia, and low-grade fever may occur; pulmonary metastases can cause cough and chest pain.
6. Neurovascular compression
Nerve compression may cause radiating pain or sensory changes, while vascular compression can lead to distal edema.
7. Elevated alkaline phosphatase
Increased serum ALP may serve as an adjunct marker for treatment response assessment and disease monitoring.
8. Symptoms related to distant metastasis
Pulmonary metastasis is most common (cough, dyspnea), while bone metastasis may cause multifocal bone pain.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that osteosarcoma is highly malignant and predominantly affects adolescents, causing severe pain, a mass, and functional impairment, with metastatic spread in advanced stages. Early symptom recognition and timely standardized management are essential. Multimodal therapy centered on surgery is the cornerstone, and minimally invasive techniques provide additional options. Scientific awareness and proactive management are key factors.
