Key result
CT identification of focal nodular/water density was highly sensitive (97.8%) but had low specificity (51.5%) for differentiating dedifferentiated from well-differentiated liposarcoma.
Why the study?
Can computed tomography (CT) accurately differentiate between well-differentiated and dedifferentiated retroperitoneal liposarcoma?
Population
78 patients with retroperitoneal liposarcoma who underwent surgery at the University of Texas M. D. Anderson…
Comparison
Computed tomography scan interpretation vs Final histopathologic diagnosis (gold standard)
Design
Cohort, radiologist who was blinded to the final histopathologic diagnosis

CT lacks specificity to rule in dedifferentiated liposarcoma; supports biopsy confirmation and leaves open prospective validation of imaging markers.

Can computed tomography (CT) accurately differentiate between well-differentiated and dedifferentiated retroperitoneal liposarcoma?
CT features can accurately identify well-differentiated retroperitoneal liposarcoma, but CT-guided biopsy is needed to confirm dedifferentiated subtypes due to low specificity of focal nodular/water density markers.
Lahat et al. (2009) conducted an observational in Retroperitoneal liposarcoma (RPLS) (n=78). Computed tomography (CT) scan vs. Final histopathologic diagnosis was evaluated on Differentiation between well differentiated and dedifferentiated RPLS. CT identification of focal nodular/water density was highly sensitive (97.8%) but had low specificity (51.5%) for differentiating dedifferentiated from well-differentiated liposarcoma.
