Abstract
AIMS Oral squamous cell carcinoma (OSCC), a most frequent type of head-and-neck cancer, is becoming more common and posing a substantial health risk. Using a network biology strategy, this study intended to find and investigate critical genes associated with OSCC. MATERIALS AND METHODS The extended protein-protein interaction networks for differentially expressed genes related to smoking and nonsmoking conditions of OSCC were constructed and visualized using Cytoscape software. The hub genes/proteins were determined based on degree and betweenness centrality measures and then evaluated and validated for expression using the Gene Expression Profiling Interactive Analysis 2 (GEPIA2), and their relationship to the sensitivity of small molecules was discovered utilizing the Gene Set Cancer Analysis (GSCA) web server. RESULTS A total of 596 differentially expressed genes were screened, and four genes, interleukin (IL)-6, JUN, tumor necrosis factor (TNF), and vascular endothelial growth factor A (VEGFA), were identified as hub proteins, and their expression and overall survival in head-and-neck cancers were further investigated using GEPIA2. TNF and VEGFA gene expressions were considerably greater in cancers when compared to normal samples, while JUN and IL-6 gene expressions were not statistically significant. Further, these hub proteins are found to have a substantial favorable correlation with overall survival of head-and-neck cancer patients. Finally, GSCA was used to predict gene-specific potential drugs that act on these molecules by combining mRNA expression and drug sensitivity data from the Genomics of Drug Sensitivity in Cancer and the Cancer Therapeutics Response Portal. CONCLUSIONS The hub genes/proteins identified in this study could help researchers better understand the molecular processes involved in the progression and metastasis of oral cancer in smokers.

Abstract
Background As the progressive trends in the field of immunotherapy, it is very favourable to reconsider the role played by B lymphocytes in the tumor microenvironment. Both the protumorogenic and antitumorogenic responses have to be evaluated to formulate an effective immunotherapeutic protocol. Aim and objective The study was primarily conducted to assess the qualitative expression of B lymphocytes in pretumorogenic (oral epithelial dysplasia) and tumorogenic environment (oral squamous cell carcinoma). The differential immunohistochemical staining of CD 20 immune marker was assessed in about 60 cases that included 30 cases of oral epithelial dysplasia and 30 cases of oral squamous cell carcinoma. Results The study found significant correlation between CD 20 IHC immune expression and histopathological diagnosis along with significant correlation between the subject's age group and histopathological diagnosis. Conclusion Modulating the immune response in a precancerous state can be highly beneficial in implementing better immunotherapeutic strategies to treat or prevent malignancy at an early stage.

Abstract
OBJECTIVES Oral cancer is the ninth most common cancer worldwide and a leading cause of cancer-related death. Oral squamous cell carcinoma (OSCC) accounts for 90% of all oral cancers. Autophagy is a conserved essential catabolic process related to OSCC. The aim of this study was to elucidate diagnostic and prognostic autophagy-related biomarkers in OSCC. METHODS The OSCC gene expression data set was obtained from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) between the OSCC samples and adjacent healthy tissues were identified by R software. The Human Autophagy Database was screened, which revealed 222 autophagy-related genes. The autophagy-related DEGs were identified. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were applied. Protein-protein interaction network analysis was performed in the STRING database. cytoHubba in the Cytoscape software was applied to determine the top 10 hub genes. The data set of patients with OSCC from The Cancer Genome Atlas (TCGA) was used to evaluate the prognostic value of the 10 hub genes. The association between prognosis-related hub genes and immune infiltrates was explored. RESULTS Twenty-seven autophagy-related DEGs were identified. The top 10 hub genes were CCL2, CDKN2A, CTSB, CTSD, CXCR4, ITGA6, MAP1LC3A, MAPK3, PARP1, and RAB11A. ITGA6 was identified as the most efficient biomarker. Receiver operating characteristic curve analysis indicated that ITGA6 had the highest diagnostic accuracy for OSCC (area under the curve = 0.925). ITGA6 expression was significantly related to immune infiltrates. CONCLUSIONS The autophagy-related gene ITGA6 might be an efficient diagnostic and prognostic biomarker in OSCC.

Abstract
BACKGROUND Ulcerative colitis is a chronic inflammatory disease with apparent extraintestinal manifestations, including in the oral cavity. Oral epithelial dysplasia, an exclusive histopathological diagnosis that is used to predict malignant transformation, has never been reported with ulcerative colitis. Herein, we report a case with ulcerative colitis that was diagnosed via extraintestinal manifestations of oral epithelial dysplasia and aphthous ulceration. CASE PRESENTATION A 52-year-old male suffering from ulcerative colitis came to our hospital complaining of pain on his tongue with a history of 1 week. Clinical examination revealed multiple painful oval ulcers on the ventral surfaces of the tongue. Histopathological examination indicated ulcerative lesion and mild dysplasia in the adjacent epithelium. Direct immunofluorescence demonstrated negative staining along the junction of the epithelium and lamina propria. Immunohistochemical staining with Ki-67, p16, p53 and podoplanin was used to rule out the reactive cellular atypia to inflammation and ulceration of the mucosa. A diagnosis of aphthous ulceration and oral epithelial dysplasia was made. The patient was treated with mouthwash (composed of lidocaine, gentamicin and dexamethasone) and triamcinolone acetonide oral ointment. Oral ulceration healed after one week of treatment. At the 12-month follow-up, minor scarring was observed on the right ventral surface of the tongue, and the patient felt no discomfort in the oral mucosa. CONCLUSION Oral epithelial dysplasia might also occur in patients with ulcerative colitis despite the low incidence, which should broaden the understanding of oral manifestations of ulcerative colitis.

Abstract
OBJECTIVES Oral squamous cell carcinomas (OSCCs) are often diagnosed late. This study aimed to determine how frequently oral epithelial dysplasia (OED) transforms to OSCC and to identify histological features that could influence the rate of malignant transformation. MATERIALS AND METHODS The study was a retrospective analysis of OED over 29 years at the Institute of Dentistry, University of Turku, Finland. OEDs with co-existing carcinomas were excluded from the data (5.8%). OED patients who developed carcinoma were identified from the Finnish Cancer Registry database. RESULTS Altogether 681 OED patients had a mean age of 59.0 years, and the male:female ratio was 0.67. Of all OED samples, 21.8% were on the tongue, followed by lining mucosa (21.3%), lip (5.3%), and masticatory mucosa (4.85%). In addition, 46.7% had no location cited. The prevalence of mild dysplasia was 62.4%, moderate dysplasia 29.1%, and severe dysplasia 3.2%. Of the patients, 94.7% had an additional histological diagnosis alongside OED. Candidiasis, lichenoid inflammation, and ulcer were found in 18.2%, 0.0%, and 22.7% of severe dysplasias, in 12.1%, 12.2%, and 22.7% of moderate dysplasias, and in 6.6%, 12.2%, and 15.8% of mild dysplasias, respectively. An additional histopathological diagnosis did not increase the risk for OED to transform to OSCC. In a mean time of 5.2 (range 0.7-29.0) years, 7.5% of OED patients developed OSCC. CONCLUSIONS Location on the tongue and the more severe OED grades increased the risk of malignant transformation of OED. These patients may benefit from an intensified follow-up schedule to ensure early diagnosis of OSCC.

Abstract
BACKGROUND AND AIM Oxidative stress leads to a compensatory increase in levels of serum ceruloplasmin in patients with such imbalances. Greater than normal serum ceruloplasmin levels are noticed in numerous cancers including the leukemias and Hodgkin's lymphoma. The purpose of the present study was to estimate and evaluate the efficacy of serum ceruloplasmin levels as a potential biomarker in the early detection of oral potentially malignant epithelial lesions (PMELs) including leukoplakia, oral submucous fibrosis (OSMF), and oral squamous cell carcinoma (OSCC) patients. MATERIALS AND METHODS The present observational study was conducted over a period of 2 years wherein 100 subjects aged between 18 to 60 years were divided into four groups with Group A consisting of 25 healthy controls, Group B and C with 25 patients each, clinically diagnosed with oral leukoplakia and OSMF and Group D with 25 patients clinically diagnosed and histopathologically proven OSCC. The patients were subjected to incisional biopsy after routine hematological investigation while the same sera samples were used for analysis of serum ceruloplasmin levels. STATISTICAL ANALYSIS USED Comparison of serum ceruloplasmin levels between the groups was performed using one way analysis of variance (one way ANOVA) test while P < 0.05 was considered statistically significant. RESULTS The mean serum ceruloplasmin levels were found to be 43.19 ± 1.90mg/dl in subjects of group A, 47.68 ± 1.51mg/dl in group B, 47.74 ± 1.45mg/dl in group C and 47.73 ± 0.74mg/dl in group D. Using one-way ANOVA, statistically significant variations were found in the values of mean serum ceruloplasmin levels in subjects of the four groups (F-value = 59.58, P = 0.0001). CONCLUSIONS The observations of the present study revealed that serum ceruloplasmin levels were found to be raised in all 3 study groups including oral leukoplakia, OSMF and OSCC as compared to the controls while the results were found to be statistically significant.

Abstract
The prognosis of patients with oral squamous carcinoma (OSCC) largely depends on the stage at diagnosis, the 5-year survival rate being approximately 30% for advanced tumors. Early diagnosis, including the detection of lesions at risk for malignant transformation, is crucial for limiting the need for extensive surgery and for improving disease-free survival. Saliva has gained popularity as a readily available source of biomarkers (including cytokines) useful for diagnosing specific oral and systemic conditions. Particularly, the close interaction between oral dysplastic/neoplastic cells and saliva makes such fluid an ideal candidate for the development of non-invasive and highly accurate diagnostic tests. The present review has been designed to answer the question: "Is there evidence to support the role of specific salivary cytokines in the diagnosis of OSCC?" We retrieved 27 observational studies satisfying the inclusion and exclusion criteria. Among the most frequent cytokines investigated as candidates for OSCC biomarkers, IL-6, IL-8, TNF-α are present at higher concentration in the saliva of OSCC patients than in healthy controls and may therefore serve as basis for the development of rapid tests for early diagnosis of oral cancer.

Abstract
The global burden of oral cancer rests on India's shoulders. Distant metastasis and extensive loco-regional spread result in a dismal 5-year prognosis. Tobacco chewing is the leading etiological factor. A lack of education among the masses combined with an inundated cancer care system account for high morbidity and mortality rates. The SARS-CoV-2 shows tropism for the oral mucosa. This viral tropism is thought to get augmented in oral cancer because of the upregulation of oral mucosal receptors and enzymes which enhance viral attachment and entry. The COVID-19 disease has caused a heavy blow to the cancer care sector in India because of paucity of COVID-19 centred health care regulations. This review highlights the need for the prompt creation of a national health policy which would prioritize and allow for the resumption of oral onco-surgical in light of COVID-19 pandemic.
