Background: The American Joint committee on Cancer in their 8th edition staging manual regarded perineural invasion as one of the most important prognostic factors for Lip and Oral Cavity Squamous Cell Carcinoma, it also incorporated tumor depth of invasion in defining tumor size category in the new staging system. This study was conducted to evaluate the frequency of perineural invasion in oral squamous cell carcinoma and the effect of approaching tumor depth in this process. Materials and Methods: fifty-four formalin fixed paraffin embedded tissue blocks of radical resections of Oral Squamous Cell Carcinoma were cut and stained with Hematoxylin and Eosin stain, then evaluated for perineural invasion, with estimation of tumor depth of invasion for each case. Results: Perineural invasion was found in twenty-two cases of the study sample. The diameter of the largest nerve bundle that showed perineural invasion was found to have a positive significant correlation with tumor depth of invasion (p=0.025). Perineural invasion status in terms of (present, absent) showed a significant difference with patients’ age (p=0.037), also showed a significant association with tumor site (p=0.004), however, this association was non-significant in regard to tumor grade and stage (p=0.848, p=0.520) respectively. Conclusion: The attacking potential of preceding tumor depth and those cancers affecting young individuals may be reflected by the presence of neural infiltration by tumor cells. Tongue resected tumors should be carefully inspected for this deceptive biological process.

Abstract Oral squamous cell carcinoma(OSCC) involving tongue and buccoalveolar complex(BAC) behaves differently. Clinical features of the two subsites and their influence on pathological factors remain least analysed. Patients are divided into two groups i.e, tongue cancer and BAC cancer group, and various clinical parameters were compared. Among 474 patients 232 had tongue cancer and 242 had BAC cancer. 30% of patients with OSCC were asymptomatic at presentation except for the ulcer. Compared to tongue cancers, lesions confined to BAC presents at an advanced stage(p=0.006). Multivariate analysis showed that dysphagia in tongue cancer(p=0.020) and external swelling or lesion in BAC cancers(p=0.002) were significant predictors of an advanced stage of disease. On histopathology perineural invasion was significantly associated tongue(p=0.008) and BAC cancers(P=0.015). Among tongue cancers, those with pain and referred otalgia had a statistically significantly high depth of invasion(DOI), compared to those without pain (DOI – no pain 6.9mm, pain 9.9mm and referred otalgia 11.4mm). There is a delay in clinical presentation of OSCC. Among tongue cancers, clinical history of pain was significantly associated with depth of invasion and perineural invasion, the significance of which needs to be prospectively analysed. Clinical history in OSCC can be used as predicting factors for various pathological characters, which is subsite specific.

AbstractThe systemic inflammatory response is known to be associated with poor outcomes in patients with various types of cancer. The C-reactive protein (CRP)/albumin (Alb) ratio (CAR) has been reported as a novel inflammation-based prognostic marker. We have evaluated the prognostic value of inflammatory markers for patients with oral squamous cell carcinoma (OSCC). The study population included 205 patients treated with OSCC between 2013 and 2018. The primary predictor variable was the inflammatory markers. The primary outcome variable was overall survival (OS). Univariate and multivariate analyses were performed using a Cox proportional hazards model to identify independent prognostic factors. The CAR had the highest area under the curve (AUC) values compared with other markers in the receiver operating characteristic (ROC) curve analysis. The cutoff value for CAR was 0.032 (AUC 0.693, P < 0.001). There was a significant difference in OS when patients were stratified according to CAR, with 79.1% for CAR < 0.032 and 35% for CAR ≥ 0.032 (P < 0.001). Cox multivariate analysis identified independent predictive factors for OS: age (hazard ratio [HR] 2.155, 95% confidence interval [CI] 1.262–3.682; P = 0.005), stage (HR 3.031, 95% CI 1.576–5.827; P = 0.001), and CAR (HR 2.859, 95% CI 1.667–4.904; P < 0.001). CAR (≥ 0.032 vs. < 0.032) is a good prognostic marker in patients with OSCC in terms of age and stage.
