Introduction Papillary thyroid cancer (PTC) is the most common thyroid cancer. Metastases from PTC most commonly involve the cervical lymph nodes (CLNs). The incidence of CLN metastases (CLNM) is reported between 30 and 80% (1, 2) . Some studies

Introduction In the United States and several other countries, the incidence of papillary thyroid cancer (PTC) has significantly increased in recent decades ( 1 ). PTC is now the second most commonly diagnosed malignancy among US Latinas ( 2

To date, no research evaluating the predictive capabilities of soluble programmed cell death-ligand 1 (sPD-L1) in thyroid cancer patients has been performed. We aimed to investigate the prognostic significance of sPD-L1 expression in papillary thyroid cancer (PTC) and to evaluate the association between sPD-L1 levels with tumoural PD-L1 expression and patient outcomes. Pre-treatment levels of serum and plasma sPD-L1 were measured by ELISA in 101 PTC patients. Tissue microarrays were stained with an anti-PD-L1 antibody, clone SP263 (Ventana). The median serum sPD-L1 concentration in PTC patients was significantly higher compared to healthy controls (P = 0.028). An increased incidence of extrathyroidal extension was significantly associated with an elevated serum sPD-L1 level (P = 0.015). Patients with high serum sPD-L1 levels had significantly shorter median disease-free survival (DFS) as compared to those with low sPD-L1 levels (P = 0.011). Following multivariate analysis, serum sPD-L1 was the only statistically significant predictor for DFS. Patients with both positive serum and tumoural PD-L1 expression had a significantly shorter DFS than those in any other subgroup (P = 0.007). Our study is the first to confirm that sPD-L1 concentration is significantly associated with patient outcome in PTC. Soluble PD-L1 may provide clinicians with a non-invasive biomarker that can lessen dependence on tissue biopsies and diagnose aggressive thyroid cancers at a more treatable stage.

Introduction Papillary thyroid cancer (PTC) is a common endocrine malignancy, accounting for approximately 90% of all thyroid cancers. There are several histological variants of PTC, with conventional PTC constituting the majority of cases ( 1
