1. Clinical presentation assessment
Progressively worsening pain, nocturnal pain, a firm fixed mass, and increased local skin temperature over the lesion.
2. Imaging — plain radiography (X-ray)
Shows osteolytic destruction, periosteal reaction (Codman triangle), and a soft-tissue mass, serving as an initial screening tool.
3. Imaging — CT scan
Clearly delineates the extent of cortical destruction and mineralization; chest CT is essential for detecting pulmonary metastases.
4. Imaging — MRI
The best modality for assessing local extent, including intramedullary spread, soft-tissue involvement, and relationships to neurovascular structures.
5. Imaging — bone scintigraphy
Whole-body bone scan identifies multifocal skeletal involvement and osseous metastases, supporting staging evaluation.
6. Pathological examination
The gold standard. Core needle or open biopsy demonstrates malignant cells directly producing osteoid matrix.
7. Laboratory tests
Elevated ALP and LDH can serve as adjunct indicators for treatment response assessment and follow-up monitoring.
8. Molecular biological testing
Analysis of molecular markers and genomic alterations enables more precise classification and may identify potential therapeutic targets.
9. Daily self-monitoring for osteosarcoma
Attention to nocturnal bone pain, a local mass, and range of motion; monthly self-checking for asymmetry and prompt medical evaluation when abnormalities arise.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that osteosarcoma is highly malignant and predominantly affects adolescents, potentially causing severe pain, fractures, and metastasis; early and standardized diagnostic work-up is essential. Diagnosis should integrate clinical features, imaging, and biopsy-based pathology, and MDT-based collaboration can improve diagnostic accuracy. Early diagnosis followed by timely treatment can significantly improve prognosis.
