Background: Oral squamous cell carcinoma (OSCC) is a significant public health problem in India, accounting to 30% of all cancers with a worrying rise in incidence and related mortality. Invasive tumor front (ITF) of OSCC has been an area of histopathologic research interest, where parameters like tumor budding (TB), mode of invasion (MOI) and lymphocytic host response (LHR) are being evaluated extensively. Objectives: The aim is to study and evaluate the possible association of ITF histological parameters such as TB, LHR and MOI with known clinicopathological prognostic factors in cases of OSCC. Subjects and Methods: We reviewed and analyzed 69 cases of OSCC for routine clinicopathological parameters, TB, MOI and LHR for any significant correlation (P < 0.05 by Chi-square test) with each other and with outcome in cases where follow-up was available. Results: TB correlated significantly with histological grade, worst pattern of invasion (WPOI), Lymphnodal involvement (LNI), Lymphovascular invasion (LVI), Perineural invasion (PNI) and age; MOI correlated with WPOI, LNI, LVI and PNI; and LHR significantly correlated with WPOI, PNI, Tumor size (pT) and outcome. TB showed a strong correlation with MOI (P < 0.001) and LHR; and no significant association was noted between LHR and MOI. Among all the clinicopathological parameters, depth of invasion, pT, WPOI, PNI and LHR showed significant correlation with outcome. Conclusion: TB, MOI and LHR showed good correlation with established parameters and as they are easy and helps in prognostication, they should be included in routine histopathological reporting guidelines.
