Background: Head and neck squamous cell carcinoma (HNSCC) is an aggressive epithelial malignancy and is the most common neoplasm arising in the upper aerodigestive tract. Earlier studies have shown that salivary levels of interleukin (IL)-6 were significantly higher in patients with oral squamous cell carcinoma (OSCC) when compared to healthy individuals. They were considered as useful biomarkers for early OSCC development. Albumin levels in the saliva were shown to be elevated in medically compromised patients with poor general condition and performance status. Aim: The purpose of this preliminary research is to investigate the role of IL-6 and albumin levels in the saliva as a marker for the early diagnosis and progression of OSCC. Materials and Methods: This cross-sectional study was conducted from December 2014 to May 2015. Sixty individuals were included and two groups (with 30 individuals each) were formed – Group 1: Healthy individuals and Group 2: Patients with OSCC. IL-6 and albumin levels in the saliva were measured using commercially available kits and were compared between the two groups using Mann–Whitney U test. P value of less than 0.05 was regarded to be statistically significant. Results: Mean value of IL-6 in Group 1 (healthy) was 15.06 [standard deviation (SD) is 4.42] and in Group 2 (OSCC) was 192.15 (SD is 82.76). On comparing the two mean values, it was seen that there was a significant rise in the salivary IL-6 levels in the OSCC group when compared to the healthy group. The mean value of albumin in Group 1 (healthy) was 0.28 (SD is 0.19) and in Group 2 (OSCC) was 0.82 (SD is 0.41). On comparing the two mean values, it was seen that there was a significant rise in the salivary levels of albumin in OSCC patients when compared to the healthy group. Conclusion: This study shows that IL-6 and albumin levels in the saliva can be used as useful biomarkers for OSCC.
