Summary
Computed tomography (CT) and lymphangiography (LAG) show similar diagnostic accuracy for cancer staging. However, CT offers superior specificity, while LAG is more sensitive for early-stage tumors.
Area of Science:
- Radiology
- Oncology
- Diagnostic Imaging
Context:
- The study addresses the declining use of lymphangiography (LAG) in radiological staging.
- It compares LAG with computed tomography (CT) and lymphadenectomy histology.
Purpose:
- To evaluate the relevance of LAG as a radiological staging method.
- To correlate LAG findings with CT and histological results.
Summary:
- Diagnostic accuracy of LAG and CT is comparable (71.4% vs. 70.6%).
- CT demonstrates higher specificity (88.2%) than LAG (58.8%).
- LAG shows superior sensitivity (63.2%) for early-stage tumors compared to CT (52.6%).
Impact:
- LAG is not recommended for intrapelvic urological and gynecological tumors.
- LAG remains indicated for specific seminoma and Hodgkin's lymphoma stages.
- Future LAG use should be limited to specialized oncological centers.
