Diagnostic strategy for bone and soft-tissue tumors

Area of Science:

• Orthopaedic Oncology
• Diagnostic Imaging
• Musculoskeletal Pathology

Background:

• Effective bone tumor diagnosis requires accurate differential diagnosis based on clinical data and plain radiographs.
• Classification into non-progressive benign, progressive benign, primary malignant, or metastatic bone tumors is essential for guiding diagnostic strategy.
• Clinical assessment and imaging interpretation are foundational for appropriate patient management.

Purpose of the Study:

• To outline a diagnostic strategy for bone tumors based on initial clinical and radiographic evaluation.
• To define criteria for referral to an orthopaedic oncologist, minimizing unnecessary diagnostic procedures.
• To emphasize the importance of prompt referral for suspected malignant or aggressive bone lesions.

Main Methods:

• Clinical information gathering and interpretation of plain radiographs.
• Differential diagnosis categorization of bone tumors.
• Criteria-based referral pathway to orthopaedic oncology.

Main Results:

• A diagnostic strategy hinges on classifying bone tumors into four categories: non-progressive benign, progressive benign, primary malignant, or metastatic.
• Referral to an orthopaedic oncologist is indicated for suspected malignant or aggressive benign bone tumors without further diagnostic tests or biopsy.
• Soft-tissue masses ≥5 cm, particularly those deep to fascia, have a high probability of malignancy and warrant direct referral.

Conclusions:

• The initial diagnostic approach for bone tumors should focus on clinical and radiographic assessment for accurate classification.
• Prompt referral to specialized orthopaedic oncology care is critical for patients with suspected aggressive or malignant bone tumors or large soft-tissue masses.
• Avoiding premature diagnostic interventions like biopsies can streamline care and improve outcomes for bone tumor patients.
