Background: A comparative cross-sectional study involving oral cancer patients and healthy individuals wasdesigned to investigate associations between retinol, -tocopherol and -carotene with the risk of oral cancer.Materials and Methods: This study included a total of 240 matched cases and controls where subjects wereselected from the Malaysian Oral Cancer Database and Tissue Bank System (MOCDTBS). Retinol, -tocopheroland -carotene levels and intake were examined by high-performance liquid chromatography (HPLC) and foodfrequency questionnaire (FFQ) respectively. Results: It was found that results from the two methods applied didnot correlate, so that further analysis was done using the HPLC method utilising blood serum. Serum levels ofretinol and -tocopherol among cases (0.177±0.081, 1.649±1.670g/ml) were significantly lower than in controls(0.264±0.137, 3.225±2.054g/ml) (p<0.005). Although serum level of -carotene among cases (0.106±0.159 g/ml)were lower compared to controls (0.134±0.131g/ml), statistical significance was not observed. Logistic regressionanalysis showed that high serum level of retinol (OR=0.501, 95% CI=0.254-0.992, p<0.05) and -tocopherol(OR=0.184, 95% CI=0.091-0.370, p<0.05) was significantly related to lower risk of oral cancer, whereas norelationship was observed between -carotene and oral cancer risk. Conclusions: High serum levels of retinoland -tocopherol confer protection against oral cancer risk.
