Evaluating the Prognostic Significance of the Coefficient of Variation in Metabolic Heterogeneity from Baseline 18F-FDG PET/CT in Newly Diagnosed Diffuse Large B-Cell Lymphoma
To investigate the prognostic value of the coefficient of variation (COV) in metabolic heterogeneity assessed by baseline 18F-FDG PET/CT in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).
Key Findings:
Increased metabolic heterogeneity, as measured by COV, was associated with poorer progression-free survival (PFS) and overall survival (OS) in DLBCL patients.
COV provided additional prognostic information beyond traditional FDG uptake metrics.
Interpretation:
The coefficient of variation in metabolic heterogeneity from baseline 18F-FDG PET/CT may serve as a valuable prognostic indicator for DLBCL patients, potentially guiding treatment decisions.
Limitations:
Retrospective design may introduce selection bias.
Limited generalizability due to single-center study.
Variability in imaging protocols and interpretation.
Conclusion:
COV in metabolic heterogeneity is a promising prognostic marker for DLBCL, warranting further investigation in larger, multicenter studies.
