Note: An invasive epithelial neoplasm with varying degrees of squamous differentiation that arises from the following anatomic sites: the oral cavity, particularly oral soft tissues including the gingival and alveolar mucosa, floor of the mouth, tongue, soft and hard palates, tonsils and oropharynx. Oral squamous cell carcinomas (SCC) have a propensity to early and extensive lymph node metastases.
A 66-year-old female patient was admitted to our department with a large tumor of the tongue measuring 10 cm in diameter. The tumor occupied nearly the entire oral cavity and showed exophytic and ulcerative areas. Histological analysis revealed a low grade squamous cell carcinoma (SCC) of the tongue. Bilateral enlarged cervical lymphatic masses were also present. The extent of the tumor infiltr...
TRPM2, one member of the transient receptor potential (TRP) protein super-family, is a Ca2+-permeable channel that is activated by oxidative stress and confers susceptibility to cell death. In the human tongue specimens of carcinoma and the tongue carcinoma SCC cell lines, we observed the enhanced expression of TRPM2. By means of the whole-cell electrophysiological recording, the ADPR-induced c...
PURPOSE Amplification at chromosome 3q26.3 is a common and crucial event in head and neck squamous cell carcinoma (HNSCC), impacting significantly on tumor progression and clinical outcome. Two novel oncogenes, namely squamous cell carcinoma (SCC)-related oncogene (SCCRO) and PIK3CA (gene encoding phosphatidylinositol-3 kinase catalytic alpha-polypeptide), have been identified as targets of 3q2...
PURPOSE Overexpression of E2F-1 is associated with increased invasiveness in head and neck squamous cell carcinoma cell lines in vitro, but its significance in vivo is unknown. This study sought to determine the relationship between E2F-1 and retinoblastoma protein (pRb) expression and disease outcome in squamous cell carcinoma (SCC) of the anterior tongue. EXPERIMENTAL DESIGN pRb and E2F-1 p...
OBJECTIVE The purpose of this study was to investigate the incidence of squamous cell carcinoma (SCC) of the anterior two thirds of the tongue in a population living in central and southern Portugal, all treated at Instituto Português de Oncologia de Lisboa, Francisco Gentil (IPOLFG). STUDY DESIGN This study was a retrospective review of all patients who had a histo- pathological diagnosis of...
We compared the changes in global gene expression between an early stage (the termination of the carcinogen treatment and prior to the appearance of frank tumors) and a late stage (frank squamous cell carcinoma (SCC)) of tongue carcinogenesis induced by the carcinogen 4-nitroquinoline 1-oxide (4-NQO) in a mouse model of human oral cavity and esophageal squamous cell carcinoma. Gene ontology and...
OBJECTIVES Phosphorylated (activated) STAT3 (pSTAT3) is a regulator of numerous genes that play an essential part in the onset, development and progression of cancer; it is involved in cell proliferation and preventing apoptosis, and in invasion, angiogenesis, and the evasion of immune surveillance. This study aimed mainly to investigate the potential prognostic role of pSTAT3 expression in ora...
BACKGROUND New treatment models are needed for the management of advanced stage head and neck carcinomas (HNSCC). Vinflunine is a novel vinca alkaloid which has shown remarkable improvement in efficiency and reduced side-effects in both in vitro and in vivo studies. Better locoregional control and prevention of distant metastasis in advanced HNSCC would be welcome and, with this new efficient c...
