To investigate the relationship between pretreatment systemic immune inflammatory response index (SII), systemic inflammatory response index (SIRI), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and lymph node metastasis in patients with papillary thyroid carcinoma (PTC).Methods: A retrospective analysis was performed on 547 PTC patients treated in Meizhou People’s Hospital from January 2018 to December 2021. Clinicopathological data were collected, including gender, age, Hashimoto’s thyroiditis, maximum tumor diameter, extra-membrane infiltration, disease stage, BRAF V600E mutation, pretreatment inflammatory index levels, and lymph node metastasis. The optimal cutoff values of SII, SIRI, NLR, PLR and LMR were calculated by receiver operating characteristic (ROC) curve, and the relationship between inflammatory indexes and other clinicopathological features and lymph node metastasis was analyzed.Results: There were 303 (55.4%) PTC patients with lymph node metastasis. The levels of SII, SIRI, NLR, and PLR in patients with lymph node metastasis were significantly higher than those in patients without lymph node metastasis, while the levels of LMR were significantly lower than those in patients without lymph node metastasis (all p 0.6). The results of regression logistic analysis showed that age 1cm (OR: 2.681, 95% CI: 1.819– 3.952, p 1cm, BRAF V600E mutation, SII positive, and NLR positive were independent risk factors for lymph node metastasis in PTC.Keywords: papillary thyroid carcinoma, lymph node metastasis, systemic immune inflammatory response index, systemic inflammatory response index, neutrophil-to-lymphocyte ratio
