Role of haematological parameters in oral potentially malignant disorders and oral squamous cell carcinoma-A comparative study

ABSTRACT

Context Oral squamous cell carcinoma (OSCC) is one of the most common cancers in human population and has a multifactorial aetiology. It is often preceded by oral potentially Malignant Disorders (OPMDs). Studies have shown that OSCC and OPMDs cause significant variations in various haematological parameters. Aim and objectives To assess the role of haematological parameters like haemoglobin, erythrocyte sedimentation rate, red blood cell count, white blood cell count and differential leukocyte count in OPMDs and OSCC and also to compare these parameters among OPMDs, OSCC and controls. Materials and methods Study comprises 30 diagnosed cases each of OPMDs and OSCC and 10 normal healthy age and sex-related individuals. Blood sample was collected from the patients and was evaluated for various haematological parameters by Sahli's acid haematin method, Westergren method and Coulter Counter ZF-6. Results There was a statistically significant difference in haemoglobin, red blood cell count, erythrocyte sedimentation rate, differential leukocyte count between OSCC, OPMDs and controls. Conclusion In the present study, haematological parameters were significantly altered in OPMDs and OSCC, and these variations may be useful in the prediction of malignant transformation and prognosis.
