Abstract

:Immune-related adverse events (irAEs) are often seen during Immune-checkpoint inhibitors (ICIs) treatment of various malignancies. Endocrine irAEs including thyroid dysfunctions are the most common irAEs, but their biomarkers remain unclear. In order to identify individuals who are susceptible to thyroid irAE for earlier diagnosis and appropriate follow-up, the current study is aimed to investigate biomarkers of thyroid irAE. Herein, patients with advanced malignant diseases who received ICIs treatment were prospectively studied. Clinical and laboratory examination, thyroid function and autoantibodies were evaluated at baseline, and every 4 weeks after first treatment with ICIs. Cytokines/chemokines were measured at baseline and at 4 weeks. In vivo effects of ICIs on experimental autoimmune thyroiditis were evaluated. Twenty-six patients with malignant diseases who received ICIs treatment were enrolled in the study. Patients were divided into 2 groups; those who developed thyroid irAE, and those without irAEs. Comparing the two groups, early increase (≤ 4 weeks) in serum thyroglobulin (Tg) levels and thyroid autoantibodies was seen in thyroid irAE (P < 0.05). Notably, higher levels of serum IL-1β, IL-2, and GM-CSF at baseline, and early decrease of IL-8, G-CSF, and MCP-1 were significantly associated in the development of thyroid irAE (P<0.05). In vivo effects of anti-PD-1 antibody on deterioration of mice experimental thyroiditis were seen. In conclusion, early change in Tg, thyroid autoimmunity, and cytokine levels might indicate development of thyroid irAE. Pre-existing thyroid autoimmunity might be involved with the development of thyroid irAE. Potential application of these factors as surrogate biomarkers for tumor therapy was indicated.

METHODS:OBJECTIVES:To assess the prevalence of Hashimoto thyroiditis (HT) in primary thyroid lymphoma (PTL) and whether it differs between mucosa-associated lymphoid tissue (MALT) lymphoma and diffuse large B-cell lymphoma (DLBCL). METHODS:Electronic databases were searched for studies assessing HT prevalence in PTL, based on antithyroid antibodies, clinical history, or pathology. Pooled prevalence of HT and its association with histotype (MALT or DLBCL) were calculated. RESULTS:Thirty-eight studies with 1,346 PTLs were included. Pooled prevalence results were 78.9% (any HT evidence), 65.3% (antithyroid antibodies), 41.7% (clinical history), and 64% (pathology). HT prevalence was significantly higher in MALT lymphoma than in DLBCL (P = .007) and in mixed DLBCL/MALT than in pure DLBCL (P = .002). CONCLUSIONS:Overall, 78.9% of patients with PTL have any HT evidence, but only half of these had been clinically followed. The difference in HT prevalence suggests that a subset of DLBCL may not derive from MALT lymphoma.

METHODS:Background Whether chronic lymphocytic thyroiditis (CLT) influences the risk of development and the progression of papillary thyroid cancer (PTC) remains uncertain. We investigated the effects of CLT on the clinicopathologic features and prognosis of PTC. Methods Two thousand nine hundred twenty-eight consecutive patients with PTC treated between 2009 and 2017 were divided into two groups: one with chronic lymphocytic thyroiditis and one without; 1174 (40%) of the patients had coincident CLT. Results In univariate analysis, CLT correlated positively with small tumor size, frequent extrathyroidal extension, multifocal diseases, and p53 but negatively with central lymph node (LN) metastasis and BRAF mutation. In multivariate analysis, CLT was associated with extrathyroidal extension and multifocal disease; however, it was not a prognostic factor for recurrence even though it was associated with two aggressive factors. Compared with patients with PTC alone, there were more retrieved central LNs in the PTC + CLT group, and these patients also underwent more invasive diagnostic tests such as fine needle aspiration cytology and frozen biopsy of LN. Conclusions The CLT patients with PTC had better behavior features and prognoses than did those with PTC alone despite frequent multifocality and extrathyroidal extension. However, precaution may be necessary to avoid performing invasive diagnostic procedures for lateral LN metastasis and to manage the patients appropriately.

METHODS::PTPN2 is one of the members of the protein Tyrosine Phosphatases (PTPs) family. To explore the promotive effect of upregulated PTPN2 induced by inflammatory response or oxidative stress on the progression of thyroid cancer. PTPN2 level in thyroid cancer tissues and cell lines was detected. Kaplan-Meier method was applied for evaluating the prognostic value of PTPN2 in thyroid cancer patients. After stimulation of inflammatory response (treatment of IFN-γ and TNF-α), or oxidative stress (treatment of H2O2), protein level of PTPN2 in K1 cells was measured by Western blot. Regulatory effects of PTPN2 on EdU-positive staining and Ki-67 positive cell ratio in K1 cells either with H2O2 stimulation or not were determined. PTPN2 was upregulated in thyroid cancer tissues and cell lines. Its level was higher in metastatic thyroid cancer patients than those of non-metastatic ones. High level of PTPN2 predicted worse prognosis of thyroid cancer. Treatment of either IFN-γ or TNF-α upregulated protein level of PTPN2 in K1 cells. Meanwhile, H2O2 stimulation upregulated PTPN2, which was reversed by NAC administration. With the stimulation of increased doses of H2O2, EdU-positive staining and Ki-67 positive cell ratio were dose-dependently elevated. Silence of PTPN2 attenuated proliferative ability and Ki-67 expression in K1 cells either with H2O2 stimulation or not. Inflammatory response or oxidative stress induces upregulation of PTPN2, thus promoting the progression of thyroid cancer.
