Summary
Skeletal metastases, common in elderly patients from prostate or breast cancer, require multimodal imaging for diagnosis. An algorithm is proposed to guide detection and diagnosis in symptomatic and asymptomatic patients.
Area of Science:
- Oncology
- Radiology
- Diagnostic Imaging
Background:
- Skeletal metastases are the most common malignant bone tumors, primarily affecting adults and the elderly.
- Prostate and breast cancers are the leading causes in men and women, respectively.
- Common metastatic sites include the spine and pelvis, often presenting as lytic lesions.
Purpose of the Study:
- To propose an algorithm for the detection and diagnosis of skeletal metastases.
- To differentiate diagnostic approaches for symptomatic versus asymptomatic oncologic patients.
- To evaluate the efficacy of various diagnostic imaging modalities.
Main Methods:
- Multimodal diagnostic imaging including bone scintigraphy, radiography, computed tomography (CT), and magnetic resonance imaging (MRI).
- Development of a diagnostic algorithm tailored to patient symptoms and initial imaging findings.
- Consideration of bone biopsy for histo-morphological diagnosis when imaging is inconclusive.
Main Results:
- Bone scintigraphy is the initial choice for asymptomatic patients but lacks specificity.
- Radiography and CT are used for symptomatic patients or positive scans, with CT excelling in evaluating the spine and pelvis.
- MRI is crucial before biopsy to differentiate bone marrow components, particularly for spine metastases.
Conclusions:
- No single imaging modality is adequate for diagnosing skeletal metastases; a multimodal approach is essential.
- An integrated diagnostic algorithm can optimize the screening, management, and follow-up of patients.
- Multidisciplinary cooperation is vital for accurate diagnosis and patient care.
