Sažetak
Background: Oral squamous cell carcinoma (OC) is one of the ten most frequent cancers in the world, with a 5-year survival rate between 30- 60%. Melatonin (MLT) has anti-oxidant, anti- inflammatory and immunomodulating properties and is considered to contribute in protecting the oral cavity from tissue damage caused by endogenic and exogenic factors. Squamous cell carcinoma antigen (SCCA) has been recognized as a potential serum marker for various squamous cell carcinomas and other diseases. However, most of the studies on serum SCCA and OC have not distinguished SCCA1 and SCCA2, due to their similar chemical structure. It is important to mention that the two molecules play different roles in the organism. Aim of the proposed study is to determine salivary MLT and SCCA1 concentrations in patients with OC. Method: Unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) was sampled from 29 patients with OC (21 male, 8 female) and 29 age and sex matched healthy subjects (22 male, 7 female). Only patients with histologically diagnosed oral squamous cell carcinoma were included in the study. Sandwich human SCCA1 ELISA kits (My BioSource, San Diego, USA) and Melatonin direct saliva ELISA kits (IBL International GmbH, Hamburg, Germany) were used. This research has been funded by the Croatian Science Foundation (IP-09-2014-9376). Results: Melatonin UWS levels were higher in the OC than in the control group (p=0.045 ; median OC: 2.18 pg/mL(95% CI:1.37- 2.88), median control group: 0.84 pg/mL(95% CI: 0.50-1.71)). SCCA1 levels were higher in the OC group both in WUS (p=0.030 ; median OC: 244, 26 pg/mL(95% CI:133, 00 to 513, 27), median control group: 2pg/mL(95% CI: 2, 00-321, 47)) and WSS (p=0.014 ; median OC: 478, 03 pg/mL(95% CI:125, 16-618, 74), median control group: 2, 00(95% CI:2, 00- 207, 46)). Conclusion: Salivary MLT and SCCA1 could serve as satisfactory biomarkers for OC. To our knowledge, MLT and SCCA1 have not yet been measured in the saliva of OC patients.
