[PMID: 38204964 PMCID: PMC10776379 DOI: 10.1016/j.jdsr.2023.10.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 09/21/2023] [Accepted: 10/26/2023] [Indexed: 01/12/2024] Open
Abstract
Oral cancer became a very common condition. WHO estimates that there are 4 cases of lip and oral cavity cancer for every 100,000 people worldwide. The early diagnosis of cancers is currently a top focus in the health sector. Recent systematic reviews and meta-analyses have identified promising biomarkers for early detection in several original research investigations. However, it is still unclear the quality of these evidence and which biomarker performs the best in terms of early detection. Therefore, the objective was, to map the methodological and reporting quality of available oral squamous cell carcinoma (OSCC) or head/neck squamous cell carcinoma (HNSCC) systematic reviews and meta-analysis. Secondly, to evaluate diagnostic accuracy of salivary biomarkers for common craniofacial cancers and to compare the diagnostic value of different salivary biomarkers. PubMed, Scopus, Web of Science, Embase and Cochrane Library electronic databases were used to map the methodological and reporting quality of the systematic reviews and meta-analysis conducted on the HNSCC, OSCC using the AMSTAR-2 checklist. The inclusion criteria were systematic reviews and meta-analysis published in the topic of HNSCC and OSCC biomarkers. Exclusion criteria were no animal studies; original primary studies, due to limitation of competency in other languages articles with language other than English were excluded. The sensitivity and specificity were calculated for salivary biomarkers and ranked according to network meta-analysis principles. A total of N = 5893 patients were included from four meta-analysis studies. All together, these included n = 37 primary studies. n = 94 biomarkers were pooled from these four meta-analyses and categorised into the stages at which they were detected (I-IV). In OSCC, Chemerin and MMP-9 displayed the highest sensitivity, registering 0.94 (95% CI 0.78, 1.00) and a balanced accuracy of 0.93. Phytosphingosine closely followed, with a sensitivity of 0.91 (95% CI 0.68, 0.99) and a balanced accuracy of 0.87. For HNSCC, the top three biomarkers are Actin, IL-1β Singleplex, and IL-8 ELISA. Actin leads with a sensitivity of 0.91 (95% CI 0.68-0.99), a specificity of 0.67, and an overall accuracy of 0.79. Subsequently, IL-1β Singleplex exhibits a sensitivity of 0.62 (95% CI 0.30-0.88), a specificity of 0.89, and an accuracy of 0.75, followed by IL-8 ELISA with a sensitivity of 0.81 (95% CI 0.54-0.97), a specificity of 0.59, and an accuracy of 0.70. In conclusion, there was highest sensitivity for MMP-9 and chemerin salivary biomarkers. There is need of further more studies to identify biomarkers for HNSCC and OSCC.

Abstract
Objectives The poor prognosis of oral squamous cell carcinoma (OSCC) is vastly due to late diagnosis. The oral submucosal fibrosis (OSMF) is often unnoticed pathology linked with high risk of malignancy. Recently, we demonstrated that the clinicopathological alterations in OSMF and OSCC patients were correlated with cancer stem cell (CSCs) markers (CD133 and CD44). However, the parallel alterations of interleukin-1 beta (IL-1β) with CSCs expression are largely unexplored. Thus, we aimed to investigate the relationship between IL-1β alterations and CSC marker expression in both OSMF and OSCC situations. Materials and Methods A total of 135 people have signed up for the study. There were sixty each in OSMF and OSCC groups, as well as 15 healthy controls. Levels of serum IL-1β were examined by ELISA. Immunohistochemistry (IHC) was used to examine the expression of CD133 and CD44. For evaluating differential CSCs expression, IHC scoring (0-4) was utilized. Results The IHC results showed maximum subjects in the OSMF and OSCC displaying CD44 and CD133 positivity, although the extent of expression in terms of IHC scoring found variable. CD133 and CD44-positive subjects showed increased levels of IL-1β in the OSMF and OSCC group. Nevertheless, the enhancement of IL-1β is more pronounced in the OSCC cases. Further, we observed a direct link of IL-1β levels with IHC scoring. Multivariate regression analysis demonstrated a significant role for CD44 and CD133 positivity in the increase of IL-1β levels. Conclusion We concluded that concurrent simultaneous changes in CSC biomarkers and IL-1β may help with early detection of OSMF and OSCC conditions.

Pazhani J, Chanthu K, Jayaraman S, Varun BR. Evaluation of salivary MMP-9 in oral squamous cell carcinoma and oral leukoplakia using ELISA. J Oral Maxillofac Pathol 2023; 27:649-654. [PMID: 38304520 PMCID: PMC10829443 DOI: 10.4103/jomfp.jomfp_426_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 10/21/2023] [Accepted: 11/08/2023] [Indexed: 02/03/2024] Open
Abstract
Background Cancer of the lip and the oral cavity is collectively the sixth most common malignancy worldwide, out of which 90% are oral squamous cell carcinomas (OSCCs). Oral cancer survival rates depend mainly upon the stage in which it is diagnosed. Successful early detection would eventually increase the survival rate. OSCCs may be preceded by potentially malignant disorders (PMDs) that are characterised by visible clinical changes in the oral mucosa. Correct diagnosis and timely treatment of PMDs may help prevent malignant transformation in oral lesions. Oral leukoplakia (OL) is the best known potentially malignant disorder of the oral mucosa with a malignant transformation rate of about 3% to 33%. Tumour markers in saliva have emerged as a new diagnostic tool in the early detection of oral cancer. Matrix metalloproteinase 9 (MMP-9) is a gelatinase which plays an important role in tumourogenisis. The present study was done to evaluate the salivary levels of MMP-9 in OSCC and oral leukoplakia patients using enzyme-linked immunosorbent assay (ELISA). Materials and Methods The study was conducted among 102 subjects, which included 34 OSCC patients (group I), 34 OL patients (group II), and 34 healthy subjects (group III). Unstimulated saliva was collected by the passive drooling method from all the study subjects during the study period, centrifuged, and stored at -80°C. The salivary MMP-9 was estimated in mg/ml using the sandwich ELISA technique. The data were analysed using a statistical software package, EZR. One-way analysis of variance was used for the comparison of salivary MMP-9 levels in OSCC, OL, and normal oral mucosa. Scheffe's multiple comparison was carried out to compare salivary MMP-9 levels among the different histological grades of OSCC and oral epithelial dysplasia. For all statistical interpretations, P ≤ 0.0 was considered the threshold for statistical significance. Results and Conclusion The mean salivary MMP-9 level in OSCC, OL, and normal oral mucosa was 50.9 ± 5.7 ng/ml, 31.6 ± 6 ng/ml, and 16.2 ± 4.8 ng/ml, respectively. Patients with OSCC had significantly higher levels of salivary MMP-9 when compared to OL and normal mucosa. Higher levels of salivary MMP-9 were observed in poorly differentiated OSCC when compared to well and moderately differentiated OSCCs. The salivary MMP-9 was higher in severe oral epithelial dysplasia when compared to mild and moderate oral epithelial dysplasias. As malignant transformation rates are higher in patients with severe oral epithelial dysplasia when compared to mild and moderate oral epithelial dysplasia, salivary MMP-9 could be considered as a surrogate marker of malignant transformation.

Abstract
This study aimed to investigate the role of a panel of salivary cytokines as biomarkers for early detection oral squamous cell carcinoma (OSCC), comparing their levels among healthy individuals, patients with oral leukoplakia (OL), and malignant lesions. Cytokine profiling analysis performed in a minimally invasive sample was correlated with clinicopathological variables in our patient cohorts. Unstimulated saliva was obtained from subjects with OSCC at early (n = 33) and advanced (n = 33) disease, OL with homogeneous (n = 33) and proliferative verrucous (n = 33) clinical presentations, and healthy controls (n = 25). Salivary IL-1α, IL-6, IL-8, IP-10, MCP-1, TNF-α, HCC-1, and PF-4 levels were analyzed by a sensitive bead-based multiplex immunoassay. Mean levels of IL-6, IL-8, TNF-α, HCC-1, MCP-1, and PF-4 differed significantly between OSCC, OL, and control saliva (p < 0.05). We found notably higher IL-6 and TNF-α in advanced compared to early OSCC stages. The area under the curve (AUC) for OSCC vs. control was greater than 0.8 for IL-6, IL-8, TNF-α, and HCC-1, and greater than 0.7 for PF-4. The presence of neck metastases (NM) was associated with increased IL-6 and TNF-α levels. Our findings suggest that salivary IL-6, IL-8, TNF-α, HCC-1, and PF-4 may discriminate between OSCC, OL, and healthy controls. IL-6 and TNF-α may indicate OSCC progression, being distinctive in the presence of NM.

Abstract
Osteopontin (OPN), a multifunctional phosphoglycoprotein also presents in saliva, plays a crucial role in tumour progression, inflammation and mucosal protection. Mucosal barrier injury due to high-dose conditioning regimen administered during autologous and allogeneic peripheral stem cell transplantation (APSCT) has neither efficient therapy nor established biomarkers. Our aim was to assess the biomarker role of OPN during APSCT, with primary focus on oral mucositis (OM). Serum and salivary OPN levels were determined by ELISA in 10 patients during APSCT at four stages of transplantation (day -3/-7, 0, +7, +14), and in 23 respective healthy controls. Results: There was a negative correlation between both salivary and serum OPN levels and grade of OM severity during APSCT (r = -0.791, p = 0.019; r = -0.973, p = 0.001). Salivary OPN increased at days +7 (p = 0.011) and +14 (p = 0.034) compared to controls. Among patients, it was higher at day +14 compared to the time of admission (day -3/-7) (p = 0.039) and transplantation (day 0) (p = 0.011). Serum OPN remained elevated at all four stages of transplantation compared to controls (p = 0.013, p = 0.02, p = 0.011, p = 0.028). During APSCT elevated salivary OPN is a potential non-invasive biomarker of oral mucositis whereas the importance of high serum OPN warrants further studies.

Abstract
BACKGROUND Oral cancer (OC) is usually diagnosed at advanced clinical stages due to its asymptomatic nature and absence of pathognomonic signs in its early development phase. Delayed diagnosis is one of the major causes of OC treatment failure and poor prognosis. Development of alternative diagnostic approaches are imperative for improving early detection and therapeutic success rates. Salivary cytokines (SC) have been studied as potential diagnostic biomarkers for OC and may represent a potential tool for improvement of its early detection. METHODS In this systematic review and meta-analysis we identified SC studied as OC biomarkers by systematically reviewing the PubMed and Cochrane Library databases using the terms: "oral cancer", "cytokine", and "saliva", and also combined with "interleukin" or "interferon". Only case-control studies that measured SC by ELISA from treatment naïve patients were included in the qualitative review. For the meta-analysis were included all comparable studies that provided enough data (sample size, mean and standard deviation or standard error of the mean) for SC levels in OC patients, non-cancer controls and patients with oral potentially malignant disorders (OPMD), including leukoplakia. Comparisons with patients with oral lichen planus (OLP) and gingivitis were included in the qualitative analysis. RESULTS A total of 28 articles (from 2004 to 2018) were included in the systematic review, describing 10 different SC, being IL-8 and IL-6 the most studied ones. SC levels were consistently higher among OC patients when compared to healthy controls and to patients with OPMD, OLP and gingivitis. Meta-analysis including 23 eligible studies showed that IL-8, IL-6, TNF-α, IL-1β and IL-10 salivary levels were significantly higher in OC patients compared to controls; and that IL-8, IL-6, TNF-α and IL-1β salivary levels were also higher in OC patients compared to individuals with OPMD. When compared to healthy controls, OPMD patients showed significantly higher IL-6 and TNF-α salivary levels. CONCLUSIONS Our analyses showed that the salivary levels of some cytokines are consistently different among OC, OPMD and healthy patients, indicating that these SC may represent potential diagnostic biomarkers for OC and OPMD. Despite of that, SC levels were highly variable among studies, suggesting that further technical improvement and standardization for SC measurement by ELISA is needed in order to successfully translate these biomarkers to the clinical practice.

Abstract
Statins are a class of lipid‐lowering drugs that have recently been used in drug repositioning in the treatment of human cancer. However, the underlying mechanism of statin‐induced cancer cell death has not been clearly defined. In the present study, we evaluated the anticancer effect of pitavastatin on oral squamous cell carcinoma (OSCC), SCC15 and SCC4 cells and found that FOXO3a might be a direct target in pitavastatin‐induced cancer cell death. Our data revealed that pitavastatin selectively suppressed cell viability and induced intrinsic apoptosis in a FOXO3a‐dependent manner in SCC15 cells while no effect was observed in SCC4 cells. Notably, treatment with pitavastatin in SCC15 cells induced the nuclear translocation of FOXO3a via dual regulation of two upstream kinases, AMPK and Akt, resulting in the up‐regulation of PUMA, a transcriptional target gene of FOXO3a. Furthermore, our data revealed that FOXO3a‐mediated PUMA induction plays a role in pitavastatin‐induced intrinsic apoptosis in SCC15 cells. Taken together, our findings suggest that pitavastatin activates the FOXO3a/PUMA apoptotic axis by regulation of nuclear translocation of FOXO3a via Akt/FOXO3a or AMPK/FOXO3a signalling. Therefore, these findings might help to elucidate the underlying mechanism of the anticancer effects of pitavastatin on OSCC.

Abstract
Background Head and Neck cancer (HNC) is the sixth most common cancer in the world. The 5-year survival rate depends on early diagnosis and appropriate therapy. Typically, late diagnosis requires not only surgical intervention, but also radiotherapy treatment combined or not with chemotherapy. Ionizing radiation is known to increase the expression of a number of cytokines involved in inflammation, wound healing and toxicity areas. Salivary cytokines have promising features to be used as biomarkers for disease screening and outcome prediction in this malignancy. The aim of this article is to analyze the role of salivary inflammatory response elements in HNC patients treated with radiotherapy, their modulation and association with the treatment outcome. Material and Methods A bibliographical search was performed on Pubmed, Cochrane and Embase using the following keywords: cytokines, saliva, head and neck cancer, radiotherapy. The cut-off point for the research were scientific papers published over the last 10 years. After a two-step selection process, 15 articles were identified and subjected to review. Results Radiotherapy treatment was shown to influence a number of salivary cytokines. A trend towards a growth of IL-1β, IL-6, IL-8, MCP-1, and TNF-α levels was observed and it correlated with the irradiation dose. Conclusions The analysis of salivary cytokines could be a useful biomarker for predicting radiotherapy outcome in HNC. However, large-scale investigations are required to validate the use of these cytokines in predicting and diagnosing HNC, as well as evaluating the response to the treatment. Key words:Cytokines, saliva, head and neck cancer, radiotherapy.

Abstract
Background: Oral cancer is one of the life threatening disease which requires an availability of a biomarker for its early detection and also for effective treatment strategies. The current study is done to evaluate the efficacy of one such biomarker i.e. TNF- α as an indicator for oral precancer and oral cancer. Objectives: To evaluate the efficacy of Tumour necrosis factor - alpha (TNF)-α as a salivary biomarker in histopathologically diagnosed cases of oral leukoplakia and Oral squamous cell carcinoma. To correlate the levels of TNF- α with varying histologic grading in Oral Squamous Cell Carcinoma and dysplasia grading in Oral leukoplakia or Hyperkeratosis. Materials and Methods: The study group included 90 subjects that were divided into three groups. OSCC (n=30), leukoplakia (n=30) and controls (n=30). Cases were selected based on inclusion and exclusion criteria of the study. Salivary samples were then collected from all three groups. Salivary levels of TNF-α were estimated using Enzyme Linked Immunosorbent Assay (ELISA). The data on concentration gradients obtained were subjected to appropriate statistical analysis. Results: The results of the present study demonstrated higher levels of salivary TNF-α in individuals with OSCC compared to leukoplakia and healthy control subjects with a high level of statistical significance. ROC curve analysis along with diagnostic parameter calculation also revealed that salivary TNF-α to be a better medium for detecting OSCC. There is also an increase in the salivary TNF-α levels with increase in the histological grade of differentiation in OSCC as well as leukoplakia. Conclusion: The present study concludes that salivary TNF – α can be used as a prognostic biomarker of OSCC. In view of the elevated levels of TNF – α in saliva of individuals with severe dysplasia, it can also be used to monitor the malignant transformation to leukoplakia to OSCC.

Abstract
The aim of this research was to investigate the value of autofluorescence imaging of oral cancer across different stages of tumor growth, to assist in detecting tumors. A xenograft mouse model was created with human oral squamous cell carcinoma cell line HSC-3 being subcutaneously inoculated into nude mice. Tumor imaging was performed with an autofluorescence imaging method (Illumiscan®) using the luminance ratio, which was defined as the luminance of the tumor site over the luminance of normal skin tissue normalized to a value of 1.0. This luminance ratio was continuously observed postinoculation. Tumor and normal skin tissues were harvested, and differences in the concentrations of flavin adenine dinucleotide and nicotinamide adenine dinucleotide were examined. The luminance ratio of the tumor sites was 0.85 ± 0.05, and there was no significant change in the ratio over time, even if the tumor proliferated and expanded. Furthermore, flavin adenine dinucleotide and nicotinamide adenine dinucleotide were significantly lower in tumor tissue than in normal skin tissue. A luminance ratio under 0.90 indicates a high possibility of tumor, irrespective of the tumor growth stage. However, this cutoff value was determined using a xenograft mouse model and therefore requires further validation before being used in clinical diagnosis.

Abstract
OBJECTIVE This study investigated the relationship between the concentration of anti-heat shock protein (HSP) 60 antibody in resting saliva and the severity of Behçet's disease (BD). METHOD Sixty-five patients diagnosed with BD at Tokyo Medical and Dental University Hospital were enrolled in this study. Based on clinical severity scores, patients were categorized as having mild, moderate, or severe BD. Periodontal status was evaluated with the Community Periodontal Index (CPI), and anti-HSP60 antibody concentrations in resting saliva were measured with an enzyme-linked immunosorbent assay. RESULTS The mean antibody concentration in patients in the moderate group was significantly higher than concentrations in the mild and severe groups. No significant difference was found between the mild and severe groups. Gingival inflammation, identified with the CPI, was associated with a higher antibody concentration. The antibody concentration in patients who had stomatitis for more than 2 weeks was significantly higher than in those with stomatitis for less than 2 weeks. The antibody concentration in patients who had taken colchicine was significantly lower than that in subjects who had not. CONCLUSION These results suggest that the concentration of anti-HSP60 antibody in resting saliva may be effective as a non-invasive indicator for the diagnosis (screening) and prognostication of BD.

Abstract
OBJECTIVE Approximately one-third of advanced head and neck squamous cell carcinomas (HNSCCs) recur within 2 years of treatment. Due to ease of collection, saliva is of interest to monitor changes that correlate with treatment. Previously this was a challenge due to xerostomia after conventional radiation. The emergence of gland-sparing radiation has made it possible to collect saliva post-treatment. This study investigated changes in cytokines in saliva pre- and post-treatment to provide foundational knowledge for future studies exploring the use of saliva to monitor treatment response. STUDY DESIGN Pre- and post-treatment saliva was evaluated for 8 cytokines by multiplex assay and enzyme-linked immunosorbent assay. RESULTS In oropharyngeal HNSCC, secretion of epidermal growth factor (EGF), GROα (Growth-regulated protein alpha), interleukin (IL)-1α, IL-β, IL-6, IL-8, tumor necrosis factor-α, and vascular endothelial growth factor increased significantly post-treatment. In additional patients, significant increases of GR-α and IL-6 were validated, but EGF showed no change. CONCLUSIONS The uniqueness of this study is its comparison of salivary cytokines from HNSCC patients pre- and post-treatment.

Abstract
Vaccination, designed to trigger a protective immune response against infection, is a trigger for mild inflammatory responses. Vaccination studies can address the question of inflammation initiation, levels, and resolution as well as its regulation for respective studied pathogens. Such studies largely based on analyzing the blood components including specific antibodies and cytokines were usually constrained by number of participants and volume of collected blood sample. Hence, blood-based studies may not be able to cover the full dynamic range of inflammation responses induced by vaccination. In this review, the potential of using saliva in addition to blood for studying the kinetics of inflammatory response studies was assessed. Saliva sampling is noninvasive and has a great potential to be used for studies aimed at analysing the magnitude, time course, and variance in immune responses, including inflammation after vaccination. Based on a literature survey of inflammatory biomarkers that can be determined in saliva and an analysis of how these biomarkers could help to understand the mechanisms and dynamics of immune reactivity and inflammation, we propose that the saliva-based approach might have potential to add substantial value to clinical studies, particularly in vulnerable populations such as infants, toddlers, and ill individuals.

Abstract
Chronic inflammation is associated with cancer development. C-reactive protein (CRP), an acute phase protein synthesized primarily in the liver, is a marker for inflammation and for the progression of many cancers. We compared serum and salivary CRP levels in 20 normal individuals, 20 patients with oral premalignant lesions and 20 patients with oral squamous cell carcinoma (OSCC) to assess its efficacy as a prognostic indicator for OSCC. Saliva and blood samples were obtained and evaluated for CRP levels. Mean CRP levels were higher in patients with oral premalignant lesions compared to controls. CRP levels in OSCC patients were elevated and were associated with advanced tumor stages.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is one of the top ten tumors threatening human health. Oral cancer overexpressed 1 (ORAOV1) identified within chromosomal region 11q13, one of the most frequently amplified regions in OSCC, has been suggested as a novel candidate oncogene in OSCC, regulating cell cycle, apoptosis, and angiogenesis. In this study, we investigated the role of ORAOV1 in OSCC-induced angiogenesis in vitro. METHODS EA.hy926 human endothelial cells were co-cultured with OSCC cells (HSC-3 and SCC-25) transfected with ORAOV1-specific shRNA to downregulate ORAOV1 expression, and analyzed for proliferation, migration, invasion, and tube formation by specific assays. RESULTS EA.hy926 endothelial cells co-cultured with ORAOV1-deficient OSCC cells exhibited significantly lower proliferation, migration, and invasion, as well as the activity in tube formation compared to that in the control cells. CONCLUSIONS Our results show, for the first time, that ORAOV1 expressed by OSCC cells promotes tube formation by endothelial cells, indicating its involvement in OSCC angiogenesis. Considering the importance of neovascularization in tumor development and metastasis, these findings suggest that targeting ORAOV1 may be a potential therapeutic strategy against OSCC.

Abstract
OBJECTIVE Sequential postoperative salivary interleukin-6 (IL-6) concentrations were examined in patients with oral squamous cell carcinoma (OSCC) who had early or late locoregional recurrences or those who did not. STUDY DESIGN Twenty-seven consecutive patients with OSCC were originally included in the study. All patients underwent radical surgery. Four saliva samples were collected before (periods I and II) and after (periods III and IV) surgery, and IL-6 concentrations were measured. RESULTS Although postoperative (period III: at the time of discharge) salivary IL-6 level was significantly higher in patients with early locoregional recurrence (P = .02) than in those without, no such relationships were observed for preoperative IL-6 concentrations (periods I and II). Postoperative (period IV: 24 months after surgery) IL-6 level was significantly higher in patients with late locoregional recurrence (P = .03) than in those without, but no such relationships were observed for IL-6 concentrations in periods I, II, and III. CONCLUSIONS Sequential postoperative salivary IL-6 concentration may be a useful marker for diagnosis of early and late locoregional recurrence in OSCC.

Abstract
Background Oral squamous cell carcinoma (OSCC) constitutes 3 percent of all cancers with predominant occurrence in middle aged and elderly males. Tumour recurrence worsens disease prognosis and decreases quality of life in patients with OSCC. Proinflammatory cytokines such as interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-α) have been suggested to play a certain role in variety of tumours. The aim of this study was to investigate the relationship of pretreatment serum IL-6 and TNF-α levels on tumour recurrence in patients with OSCC in order to identify potential biomarkers for the early detection of disease recurrence. Material and Methods The patients with newly diagnosed OSCC were treated and followed from the first visit from November 2006 until January 2008. Serum IL-6 and TNF-α concentrations were measured. The records of the patients were re-examined in July 2012 and data were recorded about cancer characteristics and tumour recurrence. Disease free survival was analyzed by Kaplan-Meier survival curves, log rank test and Cox proportional hazards regression. Results Serum IL-6 was shown as an independent risk factor for tumour recurrence. Conclusions Pretreatment serum IL-6 concentration may be a useful biomarker for identification of OSCC patients with increased risk of the disease recurrence. Key words:
Serum IL-6, serum TNF-α, oral cancer, recurrence.

Abstract
BACKGROUND Salivary and serum levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) have previously been studied in oral cancer with conflicting results. METHODS 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. RESULTS 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). CONCLUSIONS 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 larger sample is still necessary.
