Introduction: Oral Squamous Cell Carcinoma (OSCC) is a common malignancy involving head and neck. Identifying the markers of molecular levels or biochemical markers involving the various metabolic reactions associated with the initiation and biological behavior of individual tumors are very important in diagnosis and prognosis. Aim: To measure and compare the levels of serum Homocysteine (Hcy) and serum folate in OSCC patients, smoking group and healthy subjects and also to assess the clinical utility of serum Hcy as a potential tumor marker in OSCC. Materials and Methods: The study group comprised of 60 subjects, of whom 30 were classified as OSCC cases (GROUP I) and 15 were classified as smokers without OSCC (GROUP II). The control group included 15 healthy individuals without smoking habit (Group III). Hcy was measured with High Performance Liquid Chromatography (HPLC). Folate estimation was done by Chemiluminiscence Immuno Assay (CLIA). Comparison of mean Hcy and folate values among the groups was done using ANOVA with Post-Hoc Games Howell test. Gender was compared using Chi-square test. Comparison of mean age was using ANOVA with Post-Hoc Tukey’s test. Results: The mean serum folate level in OSCC patients was 5.34ng/mL, 7.68ng/mL in smoking group and 10.99ng/mL in control group. There was a significant difference in the mean serum folate levels among the three study groups (p<0.001). The mean serum Hcy in OSCC patients was 23.58µmol/L, 17.46µmol/L, in smoking group and 10.76µmol/l in controls. There was a significant difference in the mean serum Hcy levels among the three study groups (p<0.001). Conclusion: The present study found an interesting association with serum Hcy and folate levels in OSCC which could be useful as a biochemical “Tumor Marker” and thereby providing insights into the onset and progression of the disease.
