Oxidative stress is known to play a pivotal role in the development of oral squamous cell carcinoma (OSCC). We have demonstrated that activation of the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway has chemopreventive effects against oxidative stress-associated OSCC. However, Nrf2 have dual roles in cancer development; while it prevents carcinogenesis of normal cells, hyperactive Nrf2 also promotes the survival of cancer cells. This study is aimed to understand the function of Nrf2 in regulating cellular behaviors of OSCC cells, and the potential mechanisms through which Nrf2 facilitates OSCC...

Despite improvement in preoperative imaging, surgical technique, and adjuvant therapy, the prognosis of patients with tongue squamous cell carcinoma (SCC) is still unsatisfactory. The mammalian target of rapamycin (mTOR) play a key role in the regulation of tumor cell proliferation and survival. However, the significance of mTOR on the prognosis of tongue SCC remains largely undefined. In the present study, immunohistochemistry was performed to evaluate the expression of phosphorylated mTOR (p-mTOR) in 160 surgically resected tongue SCC, and correlated with survival...

H19 is involved in tumor metastasis and associated with tumor progression. Enhancer of zest homolog 2 (EZH2) is overexpressed in multiple cancer types and correlates with tumor proliferation, epithelial-mesenchymal transition, and poor prognosis. However, the interaction between H19 and EZH2 to promote tongue squamous cell carcinoma (TSCC) progression remains largely uncharacterized. Insitu hybridization and quantitative reverse-transcription PCR (qRT-PCR) were performed to measure H19 expression in primary TSCC and adjacent normal tissues and cell lines...

Human papillomavirus (HPV) 16 is the most common high-risk HPV type identified in oropharyngeal and cervical neoplasia. Recently, HPV-associated oral epithelial dysplasia with specific histopathologic features and demographics similar to HPV-oropharyngeal carcinoma has been identified. The objective of this study was to evaluate histopathologically all cases of HPV-oral epithelial dysplasia seen in one center and identify HPV types in a subset of cases. Cases with specific histopathology for HPV-oral epithelial dysplasia that were positive both by immunohistochemical studies for p16 and by in situ hybridization for high-risk types of HPV were further analyzed using QIAamp DNA Tissue Kits (Qiagen, Hilden, Germany)...

OBJECTIVES: Conditional relative survival (CRS) describes the survival chance of patients who have already survived for a certain period of time after diagnosis and treatment of cancer. Thus, CRS can complement the conventional 5-year relative survival, which does not consider the time patients have survived after their diagnosis. This study aimed to assess the 5-year CRS among Korean patients with oral cancer and the related risk factors. MATERIALS AND METHODS: We identified 15,329 oral cavity cancer cases with a diagnosis between 1993 and 2013 in the Korea Central Cancer Registry...

Spindle cell carcinoma (SpCC), which predominantly arises in the oral, pharyngeal and laryngeal mucosal tissues, is composed of a mixture of squamous and sarcomatoid components. The present study describes the case of a 62-year-old woman with SpCC recurrence 4 years after an initial surgery to remove a well-differentiated primary squamous cell carcinoma (SCC) of the tongue. The recurrent tumor was spherical and located deep within the tongue tissue, which differs from the typical manifestation of ulcerated masses of the mucosa...

Head and neck squamous cell carcinoma is one of the most common cancers with a 50% 5-year survival rate. Understanding the mechanisms that control development, progression, and spreading of the tumor to distal sites is of paramount importance to develop effective therapies. Here, we describe a minimally invasive procedure, which enables performing intravital microscopy of the mouse tongue in models for oral cancer and provides structural and dynamic information of the tumors at cellular and subcellular level...

INTRODUCTION: Persistent infection of human papillomavirus is known to cause cervical intraepithelial neoplasia or cancer in the cervix uteri and other HPV-associated cancers in different localization. Based on epidemiological and biological data, principally the high risk HPV is responsible for development of cervical these cancers. However, we have no information about the frequently distribution of different HPV types and what is the correlation between the HPV types and cytological diagnosis in cervical intraepithelial neoplasia (CIN)...

Pyruvate kinase M2 (PKM2) has been verified to correlate with the prognosis of many types of cancer. However, its role in the development and metastasis of tongue squamous cell carcinoma (TSCC) remains unclear. The immunohistochemistry (IHC) results confirmed that PKM2 is overexpressed in patients with TSCC. PKM2 up-regulation was related to lymph node metastasis and associated with reduced overall survival. According to the microarray analysis and Western blots, PKM2 expression was up-regulated in TSCC cells with enhanced metastatic potential...

Squamous cell carcinomas (SCCs) are common oronasal tumors in nonhuman primates. In this study, 11 cases of oronasal SCC in François' langurs ( Trachypithecus francoisi ) are described. Five initial cases were discovered on review of the North American François' langur studbook, with a potential familial pattern observed. The studbook was used to identify related individuals, and records were requested for review. Six additional cases were documented, and samples from all cases were submitted for microscopic review, as well as polymerase chain reaction (PCR), immunohistochemistry (IHC), and in situ hybridization (ISH), for generic papillomaviruses and PCR for herpesviruses because either virus may cause SCC in humans and other nonhuman primates...

INTRODUCTION: Recent evidence suggests that the local renin-angiotensin system has been implicated in various malignancies. The mitochondrial assembly receptor is a newly identified receptor for angiotensin peptides, angiotensin-(1-7), and has an important role in the renin-angiotensin system. However, the role of the mitochondrial assembly receptor in the prognosis of cancer patients remains unclear. The aim of this study was to evaluate the significance of mitochondrial assembly receptor signaling in the prognosis of oral tongue squamous cell carcinoma...

BACKGROUND/AIM: Total glossectomy without laryngectomy for large tongue carcinomas still remains controversial, as these defects may go along with dramatic effects on respiration, speech and swallowing. As a consequence, these procedures significantly impact quality of life. Therefore, larger case series are rare. Nevertheless, with the development of free tissue transfer, functional reconstruction has become increasingly popular and encouraging results are reported in the literature...

Embelin is an active ingredient of traditional herbal remedies for cancer and other diseases. Recently, it has been suggested that autophagy may play an important role in cancer therapy. However, little data are available regarding the role of autophagy in oral cancers. Therefore, we conducted this study to examine whether Embelin modulates autophagy in Ca9-22. Our results showed that Embelin had anticancer activity against the Ca9-22 human tongue squamous cell, and we observed that autophagic vacuoles were formed by MDC and AO...

INTRODUCTION: The cervical lymph node metastasis (CM) is one of the most important prognostic factors for oral squamous cell carcinoma. Although the frequency and distribution of CM for tongue carcinoma (TC) are well documented in the literature, there is only little data on metastasis patterns depending on the location of the cancer within the tongue. MATERIALS AND METHODS: In a retrospective study all patients with a T1-T2 TC who were treated between 1997 and 2013 were analysed regarding epidemiological data, risk factors, and tumour parameters such as exact localization, CM...

Surgical accesses for the facial skeleton are based on the concept of modular osteotomies. Various techniques and combination of osteotomies facilitate access to the most inaccessible tumors of craniomaxillofacial region. Most appropriate surgical access is determined by considering size, location, extension of the tumor, and experience of the surgical team. These are primarily used for tumors in the nasopharynx or the skull base. The aim of this paper is to review surgical accesses that aid in removal of inaccessible tumors of craniomaxillofacial region with series of cases operated in the Department of Oral and Maxillofacial Surgery, Armed Forces Medical College, Pune, India, between July 2008 and June 2010...
