PURPOSE: The constitutive activation of the Ras-MEK-ERK signaling pathway in oral cavity squamous cell carcinoma (OSCC) has been found to be tightly controlled at multiple levels under physiological conditions. RASA1 and SPRED1 are two important negative regulators of this pathway, but the exact regulating mechanism remains unclear. In this study, we aimed to explore the potential regulating mechanisms involved in the Ras-MEK-ERK signaling pathway in OSCC. MATERIALS AND METHODS: MicroRNA (miRNA) expression was detected by quantitative reverse-transcription polymerase chain reaction...

BACKGROUND: The skin and soft tissues of the face and neck have a rich plexus of dermal-subdermal vessels, which creates the possibility of raising a fasciocutaneous flap based on this vascular supply. A turned in fasciocutaneous island flap (TIFCIF) from an adjacent area of the defect can provide a simple substitute to many complex reconstructive procedures. MATERIALS AND METHODS: Fifteen patients underwent wide excision for oral cancer and upper neck dissection, maintaining bone framework, between August 2010 and June 2014...

Oral squamous cell carcinoma (OSCC) is the most prevalent neoplasia of oral cavity worldwide and prognosis remains unchanged in decades. Recently, different authors reported that head and neck squamous cell carcinomas have a subpopulation of tumor initiating cells that apparently correspond to cancer stem cells (CSC) and are also responsible for tumor growth and metastasis. The purpose of the present study was to investigate the microscopic and phenotypic characteristics of OSCC tumors induced after orthotopic xenoimplantation of SCC9(WT) cell line and CSC-enriched subpopulation isolated from SCC9 cell line based on high expression of the putative CSC marker CD44...

INTRODUCTION: Oral Submucous Fibrosis (OSMF) is a premalignant condition with potential malignant behaviour characterized by juxta-epithelial fibrosis of the oral cavity. In the process of collagen synthesis, iron gets utilized, by the hydroxylation of proline and lysine, leading to decreased serum iron levels. The trace element like iron is receiving much attention in the detection of oral cancer and precancerous condition like OSMF as it was found to be significantly altered in these conditions...

BACKGROUND: Head and neck cancer (HNC) patients are often challenged by treatment induced dysphagia and trismus. Traditionally, rehabilitation is initiated when loss of function has already occurred. There is increasing evidence that it is of benefit to patients to initiate an early rehabilitation process before and during treatment. HNC patients have a unique set of functional challenges such as pre- and post-treatment dysphagia, pain and weight loss. The aim of the trial is to investigate the effects of swallowing and mouth-opening exercises combined with progressive resistance training (PRT) during radiotherapy...

Resveratrol is known to be an effective chemo-preventive phytochemical against multiple tumor cells. However, the increasing drug resistance avoids the cancer treatment in oral cavity cancer. In this study, we investigated the oral antitumor activity of resveratrol and its mechanism in cisplatin-resistant human oral cancer CAR cells. Our results demonstrated that resveratrol had an extremely low toxicity in normal oral cells and provoked autophagic cell death to form acidic vesicular organelles (AVOs) and autophagic vacuoles in CAR cells by acridine orange (AO) and monodansylcadaverine (MDC) staining...

BACKGROUND: A wealth of clinical data exists in clinical documents in the form of electronic health records (EHRs). This data can be used for developing knowledge-based recommendation systems that can assist clinicians in clinical decision making and education. One of the big hurdles in developing such systems is the lack of automated mechanisms for knowledge acquisition to enable and educate clinicians in informed decision making. MATERIALS AND METHODS: An automated knowledge acquisition methodology with a comprehensible knowledge model for cancer treatment (CKM-CT) is proposed...

Oral mucositis can result in significant dysphagia, and is the most common dose-limiting acute toxicity in head and neck cancer patients receiving chemoradiotherapy. There is a critical need to determine the cellular and molecular mechanisms that underlie radiotherapy-associated discomfort in patients with mucositis. The objective was to induce oral mucositis in mice, using a clinical linear accelerator, and to quantify resultant discomfort, and characterize peripheral sensitization. A clinical linear accelerator was used to deliver ionizing radiation to the oral cavity of mice...

BACKGROUND: While the role of the gut microbiome in inflammation and colorectal cancers has received much recent attention, there are few data to support an association between the oral microbiome and head and neck squamous cell carcinomas. Prior investigations have been limited to comparisons of microbiota obtained from surface swabs of the oral cavity. This study aims to identify microbiomic differences in paired tumor and non-tumor tissue samples in a large group of 121 patients with head and neck squamous cell carcinomas and correlate these differences with clinical-pathologic features...

Background Head and neck is one of the most prevalent site for cancers along with lungs, cervix, breast and stomach. Hospital based cancer registries required for effective evaluation of diagnosis and management of cancer is inadequate in Nepal. Cancer registry system established by WHO is acquired by seven major hospitals in our country. However, data from tertiary health care centres like ours remain undocumented. Objective The objective of this study is to perform retrospective analysis of clinicohistopathological types of head and neck lesions which were eventually diagnosed as cancer in Dhulikel Hospital, a tertiary health care centre of Central East Nepal...

Corporal mechanisms attributed to cancer, such as oxidative stress or the action of cytochrome P450 enzymes, seem to be responsible of the generation of a variety of volatile organic compounds (VOCs) that could be used as non-invasive diagnosis biomarkers. The present work presents an attempt of using VOCs from exhaled breath and oral cavity air as biomarkers for oral squamous cell carcinoma (OSCC) patients. 52 breath samples were collected (3 L Tedlar bags) from 26 OSCC patients and 26 cancer-free controls...

BACKGROUND: Oral squamous cell carcinoma (OSCC) is the most common malignant tumour of the oral cavity. Detection of OSCC is currently based on clinical oral examination combined with histopathological evaluation of a biopsy sample. Direct contact between saliva and the oral cancer makes measurement of salivary metalloproteinase-9 (MMP-9) an attractive alternative. MATERIAL AND METHODS: In total, 30 OSCC patients and 30 healthy controls were included in this prospective study...

OBJECTIVE: Surgical margin status is an important prognostic factor in oral squamous cell carcinoma. The primary aim of the surgeon is to achieve a microscopically complete surgical resection during initial surgery. As there are no definite guidelines, a few surgeons use frozen section (FS) for margin assessment whereas others use gross examination (GE). STUDY DESIGN: This is a retrospective analysis of prospectively collected data from the electronic medical records of 435 oral cavity cancer patients...

The patient journey with head and neck cancer (HNC) is particularly challenging given the physical and functional impact of the cancer and treatment. The ability to perform activities of daily living can be severely compromised and have a profound impact on psychosocial well-being. These complex and long-lasting effects can affect patient quality of life for months to years and the literature shows that information for HNC patients is often insufficient. This observational cross-sectional study utilized survey methodology to investigate the informational needs of HNC patients and the preferred modalities for delivery...

Tonsillar metastases are absolutely rare. Small cell lung cancer (SCLC) is known to be the most frequent histological type of tonsillar metastases, however the way of tumor cells spreading to tonsil remains controversial. We described a case report of 76-year-old man with SCLC and tonsillar metastases, to highlight the importance of oral cavity evaluation as a part of a clinical exam and to show the rare tumor cells spreading.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is the most frequently occurring malignant tumour in the oral cavity. OSCC arises because of multiple genetic alterations. Cell cycle aberrations and aneuploidy are reportedly among the main characteristics of cancer cells and are associated with aggressive growth and poor prognosis. METHODS: The study sample included 47 non-metastasised and 39 metastasised primary OSCC, with matched positive cervical lymph nodes and 17 normal oral mucosa samples...

A 76-year-old woman was referred to our hospital because of an abdominal tumor in September 2009. An irregularly shaped large tumor was detected in the right subcostal abdominal cavity on computed tomography, and was diagnosed as advanced gallbladder cancer without distant metastasis following further examination. We then performed a laparotomy. The tumor had invaded directly into the descending portion of the duodenum and transverse colon. We performed a curative resection of the tumor macroscopically. Pathological findings were moderately differentiated tubular adenocarcinoma derived from gallbladder cancer(T3N0M0, Stage III )...
