Background: Oral squamous cell carcinoma (OSCC) is a life-threatening disease. It could be preceded by oral potentially malignant disorders (OPMDs). It was confirmed that chronic inflammation can promote carcinogenesis. Cytokines play a crucial role in this process. The aim of the study was to evaluate interleukin-1alpha (IL-1α), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF-α) in tissue specimens and saliva of patients with OSCC and OPMDs. Methods: Cytokines were evaluated in 60 tissue specimens of pathological lesions (OSCCs or OPMDs) and in 7 controls (normal oral mucosa, NOM) by immunohistochemistry and in saliva of 45 patients with OSCC or OPMDs and 9 controls (healthy volunteers) by enzyme-linked immunosorbent assays. Results: Immunohistochemical analysis revealed significantly higher expression of IL-8 in OSCC specimens and TNF-α in OSCCs and OPMDs with dysplasia as compared to NOM. Moreover, expression of TNF-α was significantly higher in o...

Objective: This investigation was conducted to measure the levels of serum and salivary YKL- 40 and IL-8 in patients suffering from OLP and OSCC to assess their potential role as biomarkers of oral cancer. Methods: Forty five subjects with age ranging from 30 to 70 years were distributed into 3 groups; 15 patients having atrophic and/or erosive OLP, 15 patients suffering from OSCC and 15 systemically healthy control individuals.YKL-40 and IL-8 were identified in serum and saliva samples utilizing enzyme-linked immunosorbent assays. Results: Serum YKL-40 and salivary levels of YKL-40 and IL-8 in patients with OSCC and OLP were significantly higher than the healthy control group. In order to differentiate patients having OLP from those suffering from OSCC, our study utilized the analysis of the receiver operating curve (ROC) which showed an AUC of 0.878, 0.789, 0.789 and 0.7 for serum YKL-40, salivary YKL-40, serum IL-8, and salivary IL-8, respectively. Serum YKL-40 had the highest di...

Background and Aim: Oral cancer is one of the most common cancers of the head and neck. Considering the high prevalence and mortality percentage of oral cancer and the significant advances in immunology and identification of different cytokines, the aim of the present study was to compare the concentration of IL8 in saliva of patients with oral squamous cell carcinoma (OSCC) and healthy subjects. Methods and Materials: In this case-control study, 20 individuals with a definite histopathology diagnosis of OSCC were selected as the case group and 20 healthy subjects were selected as the control group. The two groups were matched according to age, gender, cigarette smoking and alcohol consumption, medication consumption, periodontal disease (average CAL in first molars) and absence of systemic diseases. 5 ml of unstimulated whole saliva sample was collected with spitting method from each subject and the concentrations of salivary IL-8 were compared between the two groups. Linear regression and t-test were used for statistical analysis. Results: The concentration of IL-8 equaled 741.82±122.81 pg/ml in the case group and 341.25±83.52 pg/ml in the control group and t-test showed that the concentration of IL-8 in patients with OSCC is higher than that in the control subjects and this difference is significant. (p=0.049) According to regression equation, IL-8 has a significant correlation with tumor size index (T). (p=0.011) Conclusion: The results of this study showed that the concentrations of salivary IL-8 were significantly different between the patients with OSCC and healthy subjects (p=0.049) and the concentration of IL-8 has a significant correlation with tumor size (T).
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

Introduction: Lichen planus (LP) is a relatively common chronic mucocutaneous disease that affects the skin and mucous membranes, including oral mucosa. The etiology of the disease is unknown. Some evidence suggests that the immune system and inflammation may play a role in the formation and progression of lichen planus. Some authorities believe that LP is a precancerous condition. The purpose of this study was to investigate the serum levels of the inflammatory cytokines CRP, IL-1, IL-6, and TNF-in patients with oral lichen planus and oral squamous cell carcinoma (OSCC), as well as to assess the relationship between these cytokine levels and clinical symptoms. Methods: A total of 75 subjects, with 25 in each group of oral lichen planus, healthy control, and oral squamous cell carcinoma, participated in this cross-sectional study. Serum levels of IL-1α, TNF-α, IL-6, and CRP were determined and compared. In comparison to the healthy control group, the lichen planus and oral squamous cell carcinoma groups had higher levels of CRP, IL-1α, IL-6, and TNF-α. Results: We discovered that the mean mRNA and protein levels of CRP, IL-1α, IL-6, and TNF-α were significantly higher in the blood and tissue of lichen planus and OSCC patients than in normal controls. Conclusion: Higher levels of CRP, IL-1α, IL-6, and TNF-α may be linked to OLP and oral carcinogenesis. More research with larger groups is required.
Salivary IL-8, IL-6 and TNF-α as Potential Diagnostic Biomarkers for Oral Cancer
Diagnostics, 2017
Saliva has been useful as a liquid biopsy for the diagnosis of various oral or systemic diseases, and oral squamous cell carcinoma (OSCC) is no exception. While its early detection and prevention is important, salivary cytokines expression, specifically of Interleukin-8 (IL-8), Interleukin-6 (IL-6) and Tumor necrosis factor (TNF-α), does contribute to the pathogenesis of cancer and these cytokines serve as potential biomarkers. Their excessive production plays a role in cancer progression and establishment of angiogenesis. However, other inflammatory or immunological conditions may affect the levels of cytokines in saliva. This article reviews the expression of levels of specific cytokines i.e., IL-8, IL-6 and TNF-α, their signaling pathways in the development of oral cancer, and how they are essential for the diagnosis of OSCC and updates related to it. Apart from serum, the saliva-based test can be a cost-effective tool in the follow-up and diagnosis of OSCC. Moreover, large-scale investigations are still needed for the validation of salivary cytokines.

Since morbidity and mortality rates due to oral cavity and oropharyngeal squamous cell carcinoma (OSCC) have improved little in the past 30 years, early detection or prevention of this disease is likely to be most effective. Using laser-capture microdissection, we have identified the expression of 2 cellular genes that are uniquely associated with OSCC: interleukin (IL) 6 and IL-8. These cytokines may contribute to the pathogenesis of this disease, and have been linked with increased tumor growth and metastasis.

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.
Possible role for interleukins as biomarkers for mortality and recurrence in oral cancer
The International journal of biological markers, 2015
Salivary and serum levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) have previously been studied in oral cancer with conflicting results. We designed a controlled study to assess the correlation between pretreatment salivary and serum levels of IL-6 and IL-8, and all-cause survival and cancer recurrence in oral cancer patients. Fifty-two oral cancer patients and 52 healthy control cases were selected. In univariate analysis, salivary IL-6 and IL-8 seemed to be more expressed in cases (p<0.001 and p = 0.010, respectively). Multivariate analysis showed that higher pretreatment saliva IL-6 levels were significantly associated with better survival (hazard ratio [HR] = 8.62; 95% confidence interval [95% CI], 1.21-62.50; p = 0.031). To date, this is the largest prospective controlled study that has analyzed the pretreatment salivary and serum levels of IL-6 and IL-8 in oral cancer patients, suggesting salivary IL-6 as a possible prognostic biomarker. But further validation in a ...

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
