Secondary endpoints were used to evaluate the prognostic value of GLCM-entropy for OS and PFS, the correlation between GLCM-entropy and PD-L1 tumor proportion score (TPS) status, metabolic tumor volume (MTV), standard uptake value (SUV), total lesion glycolysis (TLG), and GLRLM-short run emphasis (SRE) measured using PET/CT. Here, CD274 is linked to neoplasm.
