Prognostic Value of Preradiotherapy 18F-FDG PET/CT Volumetrics in Limited-Stage Small-Cell Lung Cancer
Positron Emission Tomography Computed Tomography
Small Cell Lung Carcinoma
This is the largest reported series to date evaluating the prognostic value of baseline PET metrics in LS-SCLC. Neither SUVmax nor other analyzed PET metrics demonstrated significant correlation with OS or LRF. MTV was correlated with DF and DFS, but this association was no longer significant after adjustment for other clinical factors. This analysis suggests that pretreatment PET scans, even with the use of advanced metrics, do not have independent prognostic value for outcomes in LS-SCLC patients after CRT.
