A Disintegrin And Metalloproteinase

AbstractObjective:A disintegrin and metalloproteinase domain containing protein 33 (also known as ADAM-33) is a member of a matrix metalloproteinase family which mediates extracellular matrix remodelling and changes in cellular adhesion. This study aimed to evaluate expression of this protein in laryngeal squamous cell carcinoma, and to determine its correlation with patients' clinicopathological characteristics.Subjects and methods:Forty paraffin blocks of laryngeal carcinoma underwent immunohistochemical staining to detect “a disintegrin and metalloproteinase-33” expression. Case records were reviewed to determine patient characteristics.Results:All epithelial, vascular and stromal staining scores were significantly increased in tumour tissue compared with controls (p < 0.001). However, patients' clinical characteristics at the time of diagnosis, and their disease extent, did not correlate significantly with the immunohistochemical staining scores.Conclusion:This study suggests that increased expression of “a disintegrin and metalloproteinase-33” may play a role in the pathogenesis of laryngeal carcinoma.

Objectives: Treatment effects in patients with laryngeal squamous cell carcinoma may vary significantly even among those with the same TNM stage. Routine preoperative blood and coagulation tests are economical and easily available hematological indicators. This study aimed to investigate the clinical predictive significance of pretreatment evaluation of plasma fibrinogen (FIB) level, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) in patients with laryngeal carcinoma. Methods: Clinicopathological and demographic data from 203 patients who underwent surgery for laryngeal carcinoma were collected and analyzed. The optimal cutoff values for FIB, NLR, and PLR were determined using receiver operating characteristic curve analysis. Univariate and multivariate Cox regression analyses were used to study the relationship between blood markers and patient survival. Results: The optimal cutoff values for FIB, NLR, and PLR were 3.05 g/L, 2.41, and 110.94, respectively. Preoperative hyperfibrinemia (FIB >3.05 g/L) was an independent prognostic factor for overall survival (OS) and disease-free survival in patients with laryngeal carcinoma. An NLR >2.41 was associated with reduced OS in patients with laryngeal carcinoma, while PLR >110.94 had no effect on prognosis in these patients. Conclusions: Fibrinogen and NLR were valuable markers in predicting survival in patients with laryngeal carcinoma and may be used to inform clinicians in designing individual treatment strategies.

Abstract Background Laryngeal squamous cell carcinoma (LSCC) is considered to be a common malignancy of the head and neck with poor prognosis for its late diagnosis, metastasis and recurrence. Growing evidence demonstrates that the dysregulation of miR-29c-3p (microRNA-29c-3p) plays an important role in various tumor processes. Our study investigates the expression of miR-29c-3p in LSCC and analyzes the correlation of its dysregulation with clinicopathologic parameters and prognosis. Methods The expression of hsa-miR-29c-3p in LSCC tissues and the adjacent normal laryngeal tissues was detected in 96 LSCC formalin-fixed paraffin-embedded tissues by quantitative real-time PCR (qRT-PCR). The SPSS statistical software package (17.0) was used to analyze the associations between miR-29c-3p expressions and various clinicopathological characteristics. The overall survival (OS) was analyzed by the Kaplan-Meier method and log-rank test, and we analyzed the independent factor of prognosis by Cox proportional hazard analysis. Results A downregulation of miR-29c-3p expression in LSCC was significantly correlated with smoking index, tumor size, tumor site, differentiation, T classification, TNM stage, and lymph node metastasis (P < 0.05), but there was no correlation with age and alcohol consumption (P > 0.05). In the multivariate survival analysis, low miR-29c-3p expression was associated with shorter overall survival (P < 0.05). Furthermore, miR-29c expression was an independent prognostic factor for laryngeal cancer patients. Conclusions MiR-29c-3p has different expression levels at different stages of tumor progression, suggesting that miR-29c-3p may be a promising biomarker for evaluating the progression of LSCC and the prognosis of patients with LSCC. MiR-29c-3p can also be a novel molecular target for anti-laryngeal cancer therapy.

Background. Tumor budding is a promising prognostic indicator in several cancers especially in colorectal cancer. However, only few studies have been conducted to assess and validate its prognostic value in laryngeal squamous cell carcinoma; none of which used pancytokeratin immunohistochemistry. In view of the modest results of treatment of laryngeal squamous cell carcinoma, the need of new prognostic indicators becomes of paramount importance. Aim of the Study. We aim to evaluate tumor budding in laryngeal squamous cell carcinoma, by haematoxylin and eosin, as well as by pancytokeratin immunohistochemistry. Material and Methods. A retrospective study on 118 cases of laryngeal squamous cell carcinoma from archives of Pathology Lab of Ain Shams University Specialized Hospital and Ain Shams University Hospitals from January 2014 to January 2017. The ENT and histopathology reports were reviewed to determine clinicopathologic data of the patients. Results. Tumor budding shows high statistically significant relations ( p = 0.0001 for each) with important clinicopathological parameters of laryngeal carcinoma (site, grade, tumor stage, lymph node stage, lymph node extracapsular invasion, and vascular invasion). The extent of tumor budding correlated with overall survival, local recurrence disease free, and distant metastasis disease free ( p = 0.001 for each). Multivariate analysis showed tumor budding to be an independent prognostic factor affecting progression-free survival. There was a moderate agreement between H&E and IHC by pancytokeratin as regards detection of budding among study cases ( kappa = 0.593 ). Conclusions. Tumor budding was correlated with poor prognostic clinicopathologic indicators in laryngeal squamous cell carcinoma. It is recommended to use pancytokeratin immunohistochemistry to evaluate tumor budding in laryngeal squamous cell carcinoma especially in confusing cases.

Objective. To investigate the possible mechanisms of oxymatrine’s role in anti laryngeal squamous cell carcinoma.Methods. We examined the effects of oxymatrine on the proliferation, cell cycle phase distribution, apoptosis, and the protein and mRNA expression levels ofHPV16E7gene in laryngeal carcinoma Hep-2 cells in vitro. TheHPV16E7siRNA inhibition was also done to confirm the effect of downregulatingHPV16E7on the proliferation in Hep-2 cells.Results. Oxymatrine significantly inhibited the growth and proliferation of Hep-2 cells in a dose-dependence and time-dependence manner. Oxymatrine blocked Hep-2 cells in G0/G1 phase, resulting in an obvious accumulation of G0/G1 phase cells while decreasing S phase cells. Oxymatrine induced apoptosis of Hep-2 cells, whose apoptotic rate amounted to about 42% after treatment with 7 mg/mL oxymatrine for 72 h. Oxymatrine also downregulated the expression ofHPV16E7gene, as determined by the western blotting and reverse transcription-polymerase chain reaction analysis. Knockdown ofHPV16E7effectively inhibited the proliferation of Hep-2 cells.Conclusions. Oxymatrine inhibits the proliferation and induces apoptosis of laryngeal carcinoma Hep-2 cells, which might be mediated by a significant cell cycle arrest in G0/G1 phase and downregulation ofHPV16E7gene. Oxymatrine is considered to be a likely preventive and curative candidate for laryngeal cancer.

Abstract Background: Laryngeal squamous cell carcinoma (LSCC) is a heterogeneous disease. In clinical practice, patients with similar clinicopathological characteristics often show different outcomes. This study evaluated the levels of primary LSCC intratumoral infiltrating lymphocytes (iTILs), tumor-infiltrating lymphocyte volume (TILV), frontier tumor-infiltrating lymphocytes (fTILs), and their relations to the patient's clinical outcome. Materials and methods: According to the 2017 study of the International TILs Working Group, hematoxyline and eosin-stained slides from 412 patients were evaluated for their morphology of tumor immune infiltration status.Results: Kaplan-Meier analysis showed that high levels of iTILs, TILV, and fTILs were significantly correlated with OS (all P<0.05). Cox regression model analysis showed that high levels of iTILs, TILV, and fTILs were independently associated with better OS (all P<0.05). Conclusion: Local inflammatory markers in patients with laryngeal squamous cell carcinoma, especially the levels of iTILs, TILV, and fTILs, are reliable prognostic factors.
