OBJECTIVE: To evaluate serum levels of interleukin (IL)-1, IL-6, IL-8, IL-10, soluble IL-2 receptor (sIL-2R), squamous cell carcinoma antigen (SCCA), tissue polypeptide-specific antigen (TPS) and vascular endothelial growth factor (VEGF) in patients with potentially malignant disorders (PMD), oral squamous cell carcinoma (OSCC), or status-post (SP) OSCC. SUBJECTS AND METHODS: Blood was collected from 47 patients, either controls or diagnosed with PMD, OSCC, or SPOSCC. Levels of cytokines and tumor marker were evaluated by ELISAs. Normal levels were based on previous studies and pathology determined by chi-square and Fisher's exact tests. P ≤ 0.05 was considered statistically significant. RESULTS: Above normal levels of SCCA were found for OSCC and dysplasia patients (33.3% and 11.1%, respectively) and high range of normal (upper 20% of the normal range) for lichen planus, SPOSCC, and dysplasia patients (6.67%, 33.3%, and 22.2%, respectively), differences that approached statistical significance (P = 0.055). No differences were found between groups for other tested markers. A progression was seen for SCCA from high range of normal in SPOSCC to a mixture of high normal and elevated in dysplasia to elevated in active OSCC, suggesting that SCCA may be correlated with cancer progression. CONCLUSION: Higher levels of serum SCCA may serve as a marker for dysplasia and progression to oral carcinogenesis.
The research examined the salivary concentrations of various biomarkers, such as OAZ1, SAT, S100P, IL-1β, and IL-8 aiming to detect early-stage oral squamous cell carcinoma (OSCC). These biomarkers show potential as indicators for detecting both pre-cancerous and cancerous states within the oral cavity. Analyzing these specific molecules in saliva could help clinicians enhance diagnostic accuracy and refine early detection methods for OSCC. The research encompassed a cohort of nine OSCC patients, ten with oral submucous fibrosis (OSF), eleven individuals with oral lichen planus (OLP), and ten healthy controls. The study focused on assessing the expression levels of key biomarkers—IL 1β, IL-8, SAT, S100P, and OAZ1 mRNA—in extracellular RNA extracted from saliva samples. This evaluation was conducted using real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) with sequence-specific primers. Additionally, receiver operating characteristic curve (ROC) curve analysis was employed to gauge the efficacy of these biomarkers in detecting OSCC. Based on the results we observe, when these five biomarkers are used together, they give a 90% predictive probability for patients with OLP, an 80% predictive probability for OSF, and an impressive 100% predictive probability for patients with OSCC (AUC = 1.000, p = 0.000). This study demonstrates the efficacy of salivary transcriptome diagnostics in detecting OSCC. This novel clinical technique has the potential to be a powerful, efficient, and reliable tool for early detection of cancer. Salivary transcriptomes can be further analyzed to evaluate their effectiveness in other important illness contexts and for regular health monitoring

The main purpose of this article is to develop a new and reliable saliva-based clinical diagnostic method for the early detection of oral squamous cell carcinoma (OSCC). This study used an immunoproteomic approach which allowed the detection of immunogenic host proteins in patients' samples using pooled human antibodies. In an attempt to investigate potential biomarkers of OSCC, two-dimensional electrophoresis (2-DE) followed by immunoblotting of saliva from patients and controls were compared. The protein spots of interest were analyzed using 2-DE image analyzer and subsequently subjected to MALDI-TOF/TOF and then matched against NCBI database. The result showed that four protein clusters, namely Human Pancreatic Alpha-amylase (HPA), Human Salivary Amylase (sAA), keratin-10 (K-10), and Ga Module Complexed with Human Serum Albumin (GA-HSA), had exhibited immunoreactivity in western blot. The results are suggestive of the potential use of the differentially expressed saliva protein as tumor biomarkers for the detection of OSCC. However, further studies are recommended to validate this finding.

Background: Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity and oral lichen planus (OLP) is considered a premalignant disease. Objectives: This study aims at comparing the salivary levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), and cancer antigen 125 (CA125) among cases with OSCC, OLP, and healthy persons. Methods: In this case-control study, salivary markers were evaluated in 55 cases (15 patients with OSCC, 20 patients with OLP, and 20 healthy persons); non-stimulated saliva samples were collected from the patients and saliva markers were measured by the enzyme-linked immunosorbent assay (ELISA) method. The data were analyzed, using SPSS 21 software and ANOVA test and P < 0.05 was regarded as significant. Results: Salivary LDH and CA125 levels were significantly higher in OSCC and OLP patients compared to the control group (P < 0.05). Salivary CRP levels were significantly higher in OSCC patients compared to OLP patients...

Objectives: The early detection of oral cancer improves patient outcomes. However, despite our growing knowledge of oral cancers, patients often present with advanced disease. The development of simple screening methods is desirable to provide an alternative to screening examinations by specialists. Thus, we developed a method of oral cancer detection among exfoliated oral mucosal cells, and we evaluated the feasibility of implementing an oral cancer screening test that is examiner independent. Material and methods: The study population consisted of 185 subjects: 89 with oral cancer, 18 with oral leukoplakia, and 78 controls. We used real-time polymerase chain reaction (PCR) to detect the biomarkers serpin peptidase inhibitor B3 (SCCA1), interleukin 15 (IL-15), and thrombomodulin (THBD). Results: The sensitivities for the detection of oral cancer and oral leukoplakia were 72.0% (77/107) with SCCA1, 75.7% (81/107) with IL-15, and 56.1% (60/107) with THBD, and the specificities were 73.1% (57/ 78) with SCCA1, 64.1% (50/78) with IL-15, and 78.2% (61/78) with THBD. Analysis of the sensitivity according to tumor size revealed that sensitivity was lower for large tumors. When analyzing the sensitivity according to the clinical growth pattern, the sensitivity was observed to be low for endophytic tumors. Conclusion: We developed an oral cancer screening test based on real-time PCR analysis of SCCA1 that is examiner independent, and the sensitivity and specificity were approximately 70%; therefore, we concluded that the performance of this method using a single biomarker was suboptimal.

Early detection and easier follow-up of oral squamous cell carcinoma (OSCC) would significantly improve the morbidity and mortality associated with it. With newer technologies, it has become possible to validate cancer biomarkers in saliva with high sensitivity and specificity. There is however a need to further validate these biomarkers in cohorts of different ethnic groups. Our objective was to validate previously evaluated salivary biomarkers in Indian population. The study enrolled 117 patients. These were grouped into subcatergories of 31 early (TNMstage I-II) and 27 late-stage OSCC (TNM stage III-IV), 30 PMOD and 29 post-treatment patients. There were 42 control subjects. We evaluated 3 protein markers, IL-1β, IL-8 and LGALS3BP using ELISA, from unstimulated saliva samples. Statistical analysis was done to calculate p-value, ROC, AUC, sensitivity, and specificity. Protein markers IL-1β and IL-8 were significantly elevated (p

Evaluation of squamous cell carcinoma antigen 1 expression in oral squamous cell carcinoma (tumor cells and peritumoral T-lymphocytes) and verrucous carcinoma and comparison with normal oral mucosa Background: Squamous cell carcinoma antigen (SCCA) is used as a prognostic marker for recurrence of squamous cell carcinoma in various sites, including head and neck. Studies suggest that its high serum levels are correlated to some clinical features, such as nodal metastasis. However, it is still unknown if high SCCA in patients with SCCA tissue expression in tumor cells are related to peripheral T-lymphocytes. Therefore, we did this study to evaluate SCCA expression in squamous cell carcinoma and verrucous carcinoma and to compare it with normal oral mucosa, also investigating the correlation between serum-based and tissue-based antigen levels. Methodology: In this study, the immunohistochemistry (IHC) technique was used to determine the SCCA1 expression pattern in 81 specimens divided into 3 groups, including oral squamous cell carcinoma, verrucous carcinoma, and normal oral mucosa. Serum-based and tissue-based antigen levels of 20 oral squamous cell carcinoma cases were compared by the western blot assay. SCCA expression was also evaluated and compared in both tumor cells and peripheral T-lymphocytes by the immunofluorescence assay. Results: Our results showed that the SCCA levels in SCC specimens were significantly lower than in verrucous carcinoma and normal and hyperplastic oral mucosa specimens. We found no correlation between the IHC expression of SCCA and serum levels. SCCA was well expressed in both tumor cells and peripheral T-lymphocytes. Conclusion: Decreasing SCCA in SCC specimens suggested that SCC tumor cells may affect more than the serum levels of SCCA in some patients. In addition, expression of SCCA in peripheral T-lymphocytes showed that both tumor cells and T-lymphocytes may cause serum SCCA.
Salivary IgA and Total Protein in Human Subjects with Oral Lichen Planus and Squamous Cell Carcinoma
West Indian Medical Journal, 2016
Purpose: The purpose of this study was to compare salivary immunoglobulin A (IgA) and total protein (TP) in patients suffering from oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC), against healthy control. Methods: In a case-control study, 20 patients with OSCC, 30 patients suffering from OLP and 50 non-involved subjects were enrolled. The mean stimulated and unstimulated saliva IgA and TP levels were assayed by the Biuret method and immunoturbidometry respectively. Statistical analysis of the ANOVA was performed. Results: The mean concentration of stimulated and unstimulated saliva IgA and TP were significantly higher in both OLP and OSCC patients compared to control. Additionally TP, but not IgA, was higher in patients with OSCC compared with OLP patients d more salivary TP than OLP patients. Conclusion: Results suggest that salivary TP but not IgA is higher in OSCC patients than OLP patients.

Oral squamous cell carcinoma (OSCC) is the most common type of head and neck cancer. The 5-year survival rate has remained below 50% over the last two decades, and new tools for early diagnosis are needed. Saliva has been used for diagnosis of several systemic diseases, and its use for diagnosis of OSCC has been sought extensively. Among the many salivary analytes for diagnosis of OSCC, accumulating evidences indicate the possibility of using salivary cytokines. Overproduction of proinflammatory, proangiogenic cytokines by OSCC cells has been reported, and their role in tumor progression and angiogenesis is well established. However, many inflammatory conditions and immunological diseases could affect the levels of cytokines in serum and saliva. This article has reviewed publications in this matter, and some strengths and weaknesses have been pointed out. Conclusively, large-scale investigations are required for validation of the use of salivary cytokines for diagnosis of OSCC, with consideration to the influential role of periodontal inflammation in their levels.
