Background: Risk factors such as chronic use of tobacco, smoking and alcohol consumption of individual’s lifestyle may possibly influence the significant role in the etiopathogenesis of precancerous lesions (PL) and Conditions (PC) and lead to oral cancer. Previous studies have revealed that genetic factors have contributed to a remarkable extent in the development of this chronic disease. Limited studies have confirmed that ABO blood groups remain reportedly possible genetic factor to the specific disease such as oral malignant. In this context, we have reported that individuals in a particular blood group are more prone to develop lesions and certain types of cancer. This has thrown a light to take up an effort to conduct this present study.

Materials and methods: The present study covering 105 patients and grouped into three subjects with 35 participants in each. a) oral squamous cell carcinoma b) oral leukoplakia and c) submucous fibrosis. Gender and age group impact was also made to understand the interaction between the focused sample groups. A separate control was gathered from a same geographical population composed of gender-matched healthy volunteers. Slide agglutination was employed for blood grouping and results were tabulated for statistical analysis.

Results: Blood group “A” exhibited a significant relationship between oral squamous cell carcinoma patient and odd ratio shown 1.74 times higher risk of developing oral cancer. Gender different and habit stimulation have increased the risk. A significant relationship was observed between ABO blood group and oral leukoplakia and oral submucous fibrosis.

Conclusion: Study inferred that blood group “A” is found to be at the high risk in developing oral malignant syndrome due to its susceptibility, whereas oral precancer is hypothesized that individual habits are the host risk factor and transformed to carcinoma by interacting genetic factors to act upon ABO blood group.
