“…Salivary screening is currently the best choice as the primary screening test for highrisk cases of OSCC because the collection procedure is noninvasive and low cost [21,22]. Several studies have demonstrated the feasibility of using salivay miRNAs and long noncoding RNAs (lncRNAs) as potential biomarkers of OSCC [23,24].…”

Background/Aims: Recent studies have demonstrated that circular RNAs (circRNAs) can serve as potential molecular markers for disease diagnosis. However, little is known about their diagnostic potential for oral squamous cell carcinoma (OSCC). This study aimed to determine the expression of circRNAs in the saliva of OSCC patients to identify novel biomarkers for OSCC screening. Methods: Microarray screening of circRNA was performed to identify differentially expressed circRNAs in saliva from 3 OSCC patients compared with 3 healthy controls. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to validate the results, and the association between these confirmed salivary circRNAs and clinicopathological features was analyzed using the chi-squared test. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic value of the circRNAs identified. Preoperative expression and postoperative expression (1 month after the surgery) of hsa_circ_0001874 and hsa_circ_0001971 was also determined. Results: Our results indicated 12 upregulated and 20 downregulated circRNAs in the saliva from the OSCC patients compared with that from the healthy controls. Among the differentially expressed circRNAs, hsa_circ_0001874, hsa_circ_0001971, and hsa_circ_0008068 were upregulated and hsa_circ_0000140, hsa_circ_0002632, and hsa_circ_0008792 were downregulated in the OSCC group versus the healthy group. Clinical data indicated that salivary hsa_circ_0001874 was correlated with TNM stage (P=0.006) and tumor grade (P=0.023) and that hsa_circ_0001971 was correlated with TNM stage (P=0.019). The combination of hsa_circ_0001874 and hsa_circ_0001971 showed an area under the ROC curve of 0.922 (95% confidence interval, 0.883-0.961; P< 0.001). The risk score based on the combination of hsa_circ_0001874 and hsa_circ_0001971 also discriminated patients with OSCC from patients with oral leukoplakia (P< 0.001). Moreover, the expression levels of salivary hsa_circ_0001874 and hsa_circ_0001971 were clearly decreased in the postoperative samples compared with preoperative samples (P< 0.001). Conclusions: This is the first study to demonstrate the potential of salivary hsa_circ_0001874 and hsa_circ_0001971 as biomarkers for the diagnosis of OSCC.

“…Future research should aim to establish saliva as a diagnostic fluid for primary screening and monitoring of disease progression in oral cancer cases due to its easy accessibility. Further benefits are that the salivary collection procedure is non-invasive, can be undertaken at low cost and without involvement of skilled personnel (47).…”

Lipid peroxidation induced by reactiveoxygen species (ROS) is involved in the pathogenesis of malignancy. Overall, lipid peroxidation levels are indicated by malondialdehyde (MDA), which is the most frequently used biomarker to detect oxidative changes. Antioxidant defense systems such as glutathione (GSH) limit cell injury induced by ROS. Therefore, MDA and GSH can be used to monitor oxidative stress (OS). Hence, this study aimed to evaluate and compare both salivary and serum levels of MDA and GSH in oral leukoplakia and oral squamous cell carcinoma (OSCC) patients, and healthy controls. The study included 100 subjects comprising 30 apparently healthy controls, 30 patients with oral leukoplakia and 40 clinically and histologically diagnosed patients with OSCC. Saliva and blood samples were obtained and evaluated for MDA and GSH. The study revealed enhanced MDA levels in saliva and serum in oral leukoplakia and OSCC patients as compared to controls. On the other hand, significant decreases were seen in serum and salivary GSH levels in oral leukoplakia and OSCC patients as compared to controls. Augmentation of OS in blood and saliva is reflected by increase in MDA and decrease in GSH levels, indicating that tumor processes cause an imbalance of oxidant-antioxidant status in cell structures.(J Oral Sci 56, 135-142, 2014)

Altered secretion of saliva and its changed composition in patients undergoing chemotherapy often results in oral mucosa pathologies. The aim of this study was to assess the impact of oral hygiene and the concentration of calcium, phosphate and magnesium ions in the saliva on developing oral mucositis in children with acute lymphoblastic leukaemia (ALL) during anticancer therapy. The study included 78 children, aged from 2 to 18 yrs suffering from ALL on anticancer therapy. The results of biochemical scores found that the concentrations of calcium, phosphate and magnesium ions in the saliva of children with ALL were affected. Oral hygiene condition and lower concentrations of selected biomarkers in the saliva in children with ALL during chemotherapy may affect the intensity of the pathological changes in the oral mucosa.In the group of children examined unstimulated saliva was collected in the morning two hours after a meal to determine the concentration of calcium, phosphorus and magnesium ions. The samples of collected saliva were centrifuged for 15 min at 5,000 rot/min. The centrifuged saliva samples were frozen at -80°C, until the time of biochemical scores.The concentration of calcium ions was determined by the colorimetric method of Arsenazo III at neutral pH, the complex was read at 660nm wavelength with the use of reagent kit Konelab™ CALCIUM, Thermo Electron Corporation.The concentration of phosphorus ions was determined calorimetrically by the direct method without deproteinization by measuring UV absorption of the resulting phosphorus-molybdenum complex formed in the acidic environment/absorption at 340 nm wavelength is proportional to the concentration of phosphate ions in the material tested. The measurement was done using reagent kit Phosphorus UV BioMerieux.The concentrations of magnesium ions were determined by colorimetric method without deproteinization, using calmagite as chromogen and the reagent kit Mg-Kit, BioMérieux.Microelements were determined on a biochemical analyzer Konelab Kone Pro.The results were analyzed statistically. The measurable parameters were presented as mean, Median, minimum and maximum values and standard deviation. Mann-Whitney U test was used to compare 2 independent groups, Spearman's Rank Order Correlation test was used to analyze the relationship between two quantitative parameters;
