abstract = {Background: Positron emission tomography (PET) parameters for a combination of the primary tumor and suspicious metastatic lymph nodes (SMLNs) appear to be more potential than those for the primary tumor alone for evaluating tumor recurrence in locally advanced cervical carcinoma (LACC), while the optimal threshold has not been determined. This study investigated the optimal PET parameters and percentage of SUVmax (%SUVmax) thresholds for tumor recurrence evaluation, and the relationship with hematological parameters in patients with LACC treated with concurrent chemoradiotherapy (CCRT).
Methods: Eighty-nine patients with advanced squamous cell cervical carcinoma (SCCC) scheduled for CCRT underwent pretreatment whole body PET/CT scans. We analyzed PET parameters including maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of the primary tumor (SUVmax-P, MTV-P, TLG-P) and the combination of the primary tumor and SMLNs (SUVmax-C, MTV-C, TLG-C). The association between PET parameters with different %SUVmax threshold and recurrence-free survival (RFS), and the correlations between PET parameters and hematological parameters including squamous cell carcinoma antigen (SCC-ag), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and hemoglobin (Hb) were evaluated.
Results: The optimal threshold for evaluating tumor recurrence was 50%SUVmax, and the optimal PET parameter was MTV-C with the 50%SUVmax threshold (MTV-C50%) (c-index =0.752). Multivariate analysis indicated that MTV-C50% [hazard ratio (HR), 1.065; P},
