MRI features of different types of sinonasan rhabdomyosarcomas: a series of eleven cases.

Objective: To retrospectively analyze magnetic resonance imaging (MRI) features of various pathological subtypes of sinonasal rhabdomyosarcoma (RMS) and explore correlations between imaging features and pathological subtypes.

Methods: In total, 11 cases with embryonal, alveolar or pleomorphic sinonasal RMSs, confirmed by surgical pathology, were selected. Their characteristics and distinctive imaging features were analysed, and the correlation between pathology and imaging features was explored.

Six-gene signature for predicting survival in patients with head and neck squamous cell carcinoma.

The prognosis of head and neck squamous cell carcinoma (HNSCC) patients remains poor. High-throughput sequencing data have laid a solid foundation for identifying genes related to cancer prognosis, but a gene marker is needed to predict clinical outcomes in HNSCC. In our study, we downloaded RNA Seq, single nucleotide polymorphism, copy number variation, and clinical follow-up data from TCGA.

A Prognostic 5-lncRNA Expression Signature for Head and Neck Squamous Cell Carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is a common malignant cancer that accounts for 5-10% of all cancers. This study aimed to identify essential genes associated with the prognosis of HNSCC and construct a powerful prognostic model for the risk assessment of HNSCC. RNAseq expression profile data for the patients with HNSCC were obtained from the TCGA database (GEO).

MiR-98 inhibits malignant progression via targeting MTDH in squamous cell carcinoma of the head and neck.

Purpose: MicroRNAs function through regulating specific target mRNA expression and then participate in the development and progression of diverse human cancers. MiR-98 shows aberrant expression and dysfunction in tumors. However, its clinical significance and exact role in squamous cell carcinoma of the head and neck (SCCHN) remain elusive.

Elevated expression of Derlin-1 associates with unfavorable survival time of squamous cell carcinoma of the head and neck and promotes its malignance.

Derlin-1 is over-expressed to function as an oncoprotein in breast, lung and colon cancers. However, the implications of Derlin-1 involved in squamous cell carcinoma of the head and neck (SCCHN) remain unknown. This study aims to investigate the effects of Derlin-1 expression on SCCHN tissues and cells.

An individual drug-therapy and genetic testing report of temporal bone verrucous carcinoma.

Objective: To investigate the pathology and pathogenesis of and treatment methods for temporal bone verrucous carcinoma.

Materials And Methods: A single-patient report of verrucous carcinoma on the left external auditory canal is presented and analyzed along with all cases of temporal bone verrucous carcinoma that have been documented in the English literature.

Results: Most of the patients with verrucous carcinoma of the temporal bone have histories of surgery, trauma, or infection, and verrucous carcinomas are sensitive to antimicrotubule chemotherapeutic medicines.

[EGCG regulates TGF-β1-induced epithelial mesenchymal transition in squamous cell carcinoma of head and neck].

Objective: To study the effect and molecular mechanism of epigallocatechin-3-gallate (EGCG) on epithelial-mesenchymal transition (EMT) in vitro induced by human recombinant TGF-β1 protein in squamous cell carcinoma of the head and neck.

Methods: EMT morphological changes of Tu686 cells were observed after sequential treatment of 5 ng/ml TGF-β1 and 20 µmol/L EGCG. Tu686 cells were collected after the treatment of 5 ng/ml TGF-β1 for 24 h and EGCG with different concentrations (0, 10, 20, 30 µmol/L) for another 24 h or 20 µmol/L EGCG treatment for different time phase (6, 12, 24 h).

Increased expression of Rab coupling protein in squamous cell carcinoma of the head and neck and its clinical significance.

The role of Rab coupling protein (RCP) has not been previously investigated in squamous cell carcinoma of the head and neck (SCCHN). The aim of this study was to explore RCP protein expression and its clinicopathological significance in SCCHN. RCP protein expression in 95 SCCHN samples, 18 vocal nodule epithelia and 16 leukoplakia epithelia samples was analyzed by immunohistochemistry and correlated with clinicopathological parameters and patient outcome.

Analysis of transcriptional factors and regulation networks in laryngeal squamous cell carcinoma patients with lymph node metastasis.

The present study was to identify and quantitate differentially expressed proteins in laryngeal squamous cell carcinoma (LSCC) tissues with or without lymph node metastasis and to explore transcriptional factors and regulation networks associated with the process. Tissue specimens were taken from 20 patients with LSCC, including 10 cases of LSCC without metastasis LSCC (N0) and 10 cases of LSCC with metastasis LSCC (Nx). Among the 643 unique proteins identified by using iTRAQ labeling and quantitative proteomic technology, 389 proteins showed an abundance change in LSCC (Nx) as compared to LSCC (N0).

Bone morphogenetic protein-4-induced epithelial-mesenchymal transition and invasiveness through Smad1-mediated signal pathway in squamous cell carcinoma of the head and neck.

Background And Aims: Bone morphogenetic proteins (BMPs) have recently been shown to be involved in the genesis and progression of a wide variety of carcinomas. The present study was undertaken to estimate the effect of BMP-4 on squamous cell carcinoma of the head and neck (SCCHN) in tissue and cell levels.

Methods: In this study, immunohistochemistry, Western blotting and RT-PCR were utilized to detect the expression of BMP-4, Smad1 and phosphorylated Smad1 in SCCHN tissues or SCCHN cell lines.
