The Holistic Review on Occurrence, Biology, Diagnosis, and Treatment of Oral Squamous Cell Carcinoma

Cureus

A prevalent head and neck cancer type is oral squamous cell carcinoma (OSCC). It is widespread and associated with a high death rate of around 50% in some regions of the world. We discuss the likelihood of developing OSCC and the impact of age in this review. Prior to examining the vast array of diagnostic indicators, a brief explanation of the biology of the disease is addressed. Finally, the therapeutic strategies for OSCC are listed. The complete literature for this study was compiled by searching Google Scholar and PubMed using the terms "OSCC," "oral squamous cell carcinoma," "diagnosis of OSCC," "oral cancer," and "biomarkers and OSCC." The research finds that OSCC has several critical parameters with a lot of room for additional in-depth study.

Advances and applications of oral cancer basic research

Oral Oncology, 2011

Oral cancer Squamous cell carcinoma Molecular biology Cancer research Advances and applications s u m m a r y Cancer of the oral cavity accounts for almost 3% of cancer cases in the world. The incidence varies widely reflecting geographic differences in exposure to risk factors. The recent rise in younger age groups and females seen in many countries is of particular concern. Treatment and management of complications, locoregional recurrence and further primary tumors result in high morbidity and mortality especially when the disease is advanced stage at initial diagnosis. Progress in cancer research has provided abundant new knowledge about cellular processes and molecular biology underlying oral carcinogenesis and tumor progression. The present review attempts to summarize the current most widely-used research approaches and their application in the prevention, diagnosis, effective treatment, and improved outcome of oral cancer.

Oral squamous cell carcinoma: diagnostic markers and prognostic indicators

2016

OSCC is the most frequent malignant tumour of the oral cavity, accounting for more than 90% of malignant tumours of this anatomic region and it often arises from precursor lesions. Aside from tobacco and alcohol consumption, further determinants have been considered to increase the risk of OSCC development, such as micronutrient deficiencies, chronic traumatism, poor oral hygiene and viruses. Recurrence, survival and conversely, mortality depends on numerous and different biological, histological, macroscopic and microscopic factors that have been investigated in order to define causes, to help diagnosis and to refine appropriate treatments that perfectly fit with the different features of OSCCs. For this purpose, during the last decades, the improvement of scientific technologies and molecular analyses have allowed to investigate markers and genetic and epigenetic factors, in order to clarify their responsibilities related to early diagnosis and OSCC progression and prognosis in or...

Oral squamous cell carcinoma, novel methods for early diagnosis and treatment

Modern Medical Laboratory Journal

Oral squamous cell carcinoma (OSCC) represents the most common oral cavity cancer worldwide, being among the 10 most frequent cancers of all types. Only around 50% of patients survive longer than 5 years in view of currently applied medical procedures of diagnosis and treatment. The delay in diagnosis accounts for the shortening of survival despite advances in treatment protocols. The poor prognosis as well as high occurrence rate exerts a burden on both patients and clinicians. Cancer biomarkers may possibly present cancer profiles of different patients and foreseeing each upcoming therapy response and the subsequent outcomes. Identification of the most fundamental biomarkers in OSCC may lead us to precise detection, which can give rise to earlier diagnosis, more effective treatment options, and more patient oriented prognostic decisions, alleviating the current situation regarding the failure in effectual OSCC management. In this review, we have outlined the molecular biomarkers for early diagnosis of OSCC and suggested inhibitors through which metastasis and its molecular pathways could potentially be inhibited.

Histological and molecular aspects of oral squamous cell carcinoma (Review)

2014

Oral squamous cell carcinoma (OSCC) represents 95% of all forms of head and neck cancer, and over the last decade its incidence has increased by 50%. Oral carcinogenesis is a multistage process, which simultaneously involves precancerous lesions, invasion and metastasis. Degradation of the cell cycle and the proliferation of malignant cells results in the loss of control mechanisms that ensure the normal function of tissues. The aim of the current review is to present the histopathological features of OSCC, including potentially malignant changes, the international classification of tumors, the tumor invasion front and tumor biomarkers (Ki-67, p53, homeobox genes and collagen type IV), as well as the tumor microenvironment and function of cancer-associated fibroblasts in the most common type of oral cancer that is encountered by dental surgeons. In OSCC, associations have been identified between the proliferation, basal lamina degradation and connective tissue modulation. Therefore, the comparison of these factors with the survival time of OSCC patients from the histopathological diagnosis is of interest

Prevention and Treatment of Oral Squamous Cell Carcinoma-A Mini Review

2022

Head and neck cancer, oral cancer, treatment, cigarette Oral squamous cell carcinoma (OSCC) is increasing day by day in its incidence and prevalence globally while its etiology differs in different parts of the world. Its risk factors, causative agents vary with regions and males are found to be dominating in using cigarettes, alcohol and gutka products, because of its easily availability and access to males in all places whereas females are more conscious about their health and esthetic value. This may be one of the reasons, which may be responsible for a high male-to-female ratio. This mini-review sheds lights on the treatment and preventive strategies available for the management of OSCC.

Squamous cell carcinoma of the oral cavity: clinical and pathological aspects

2013

Oral cavity cancer is a public health problem as the sixth leading cause of cancer worldwide. Most tumor lesions are detected in stage III and IV, leading to a poor prognosis, five-year survival rate ranging between 10% and 40%. Oral cancer etiology is multifactorial, known still incomplete. The main etiopathogenic factors are exposure to cigarette smoke and alcohol consumption. We conducted a retrospective study of oral cavity tumors hospitalized in 2008-2012 in Oral and Maxillofacial Surgery Clinic of the Emergency County Hospital of Craiova, Romania. Of 143 tumors of the oral cavity, 125 were malignant, and of these, 115 (92%) were represented by squamous cell carcinoma. Tumor lesions were more common in males (69%), patients from rural areas (64%) and those over 50-year-old (87.71%).

Pathogenesis of oral squamous cell carcinoma- An update

IP innovative publication pvt. ltd, 2019

Abstract Oral cancer is the sixth most common malignancy in the world. Oral cancer is of major concern in Southeast Asia primarily because of the deleterious habits such as smoking, betel nut chewing and alcohol consumption. Despite recent advances in cancer diagnoses and therapies, the survival rate of oral cancer patients has remained at a dismal 50% in the last few decades. This paper is an overview of the various etiological agents and risk factors implicated in the development of oral cancer. Keywords: Tobacco, Alcohol, Squamous cell carcinoma, Risk factors.
