Expression of miR-373 and its predicted target genes E-cadherin and CD44 in patients with laryngeal squamous cell carcinoma.

Expression of miR-373 and its predicted target genes E-cadherin and CD44 in patients with laryngeal squamous cell carcinoma. Cell Mol Biol (Noisy-le-grand). 2017 Dec 30;63(12):29-33 Authors: Timirci-Kahraman Ö, Verim A, Farooqi AA, Turan S, Özkan-Küçük NE, Yaylim İ Abstract Laryngeal squamous cell carcinoma (LSCC) is a genomically complex disease that is difficult to target, and efforts have been made to identify new treatment strategies and   molecular markers that might stratify patients and individualize options for treatment. miR-373 has diametrically opposed roles in different stages and types of cancers. miR-373 has been suggested to quantitatively control E-cadherin and CD44 expression. We studied the expression of miR-373, E-cadherin and CD44 in laryngeal squamous cell carcinoma and evaluated the association between the disease and clinical characteristics of patients. Tumor tissues were collected from 24 laryngeal cancer patients. Adjacent normal tissue samples were also obtained as controls. After RNA isolation, we assessed the miR-373, E-cadherin and CD44 levels. As endogenous controls, we used the small RNA U6 and GAPDH TaqMan® to normalize the levels of expression of miR-373, E-cadherin and CD44. The fold change in the expression of the genes in larynx tumor and control tissues was calculated using the 2-ΔΔCT method. miR-373 was significantly upregulated in seventeen tumor samples compared...

ConclusionFine needle aspiration cytology should be done in cutaneous nodules associated with head and neck cancers to rule out malignancy, even if it clinically appears to be benign in nature.

Conclusions: SCC-Ag moderately correlates with tumor volume in head and neck cancer patients, with statistical significance. We suggest that using tumor volume, rather than a one-dimensional measurement such as tumor size, to analyze correlation with SCC-Ag offers a more accurate means of cancer prognosis.ORL

Publication date: Available online 3 August 2018Source: Seminars in Cancer BiologyAuthor(s): Jason Y.K. Chan, Gooi Zhen, Nishant AgrawalAbstractHead and neck squamous cell carcinoma (HNSCC) represents the most common type of head and neck cancer worldwide. However, despite advances in cancer care globally there has been little progress in HNSCC, with survival remaining static and slightly worse in laryngeal squamous cell carcinoma with 5 year survivals remaining at ∼50%. Conventional analysis of tissue through cytopathology or histopathology are the mainstay of diagnosis. Furthermore there are no useful biomarke...

CONCLUSIONS: Selective SPECT/CT-guided ENI results in significant dose reductions to various organs-at-risk and corresponding NTCP values, and will subsequently reduce the incidence and severity of different troublesome radiation-related toxicities and improve quality-of-life.

Despite great enthusiasm towards immunotherapy, reliable biomarkers are still lacking. The importance of subsets based on human papillomavirus (HPV) status is supported by a growing body of evidence. However, role of other possible subgroups such as anatomic localization of primary tumor remains controversial. Our objective was to investigate immune cell infiltrate and checkpoint inhibitor proteins in above-mentioned head and neck cancer subsets. Archival tumor samples of 106 laryngeal, oropharyngeal, and hypopharyngeal cancer patients were stained with PD-L1, PD-L2, PD-1, and CTLA-4 antibodies. Proportion of tumor-infiltr...

The objective of this study was to evaluate the expression of epithelial cadherin and β-catenin in patients with laryngeal tumor. A retrospective study of 52 patients with glottic or supraglottic squamous cell carcinoma was conducted and evaluated according to the tumor site, histological differentiation, TNM stage, survival analysis and compared with the immunohistochemical expression of epithelial cadherin and β-catenin. We observed statistically significant association between the epithelial cadherin expression reduction and supraglottic localization of the lesion, the presence of cervical metastasis, poorly d...

Almeida JD Abstract Heavy metals intoxication is known to be risk factors for various diseases, including cancer. These metals may be presented in food and soil as well as in leaf and tobacco smoke. The aim of this study was to correlate the exposure to heavy metals stemming from tobacco and head and neck squamous cell carcinoma carcinogenesis. Analysis of lead, copper, manganese, arsenic, chromium, and cadmium by atomic absorption spectrophotometry was performed in whole blood samples from 91 patients: 68 smokers with oral cavity, pharynx, or laryngeal cancer; 8 non-smokers with oral or larynx cancer; and 15 non...
