Objective. Oral squamous cell carcinoma (OSCC) has a remarkable incidence over the world and a fairly strenuous prognosis, encouraging further research on the prognostic factors and new techniques for diagnosis that might modify disease outcome. Data Sources. A web-based search for all types of articles published was initiated using Medline/Pub Med, with the key words such as oral cancer, prognostic factors of oral cancer, diagnostic method of oral cancer, and imaging techniques for diagnosis of oral cancer. The search was restricted to articles published in English, with no publication date restriction (last update April, 2013). Review Methods. In this paper, I approach the factors of prognosis of OSCC and the new advances in diagnostic technologies as well. I also reviewed available studies of the tissue fluorescence spectroscopy and other noninvasive diagnostic aids for OSCC. Results. The outcome is greatly influenced by the stage of the disease (especially TNM). Prognosis also depends or varies with tumour primary site, nodal involvement, tumour thickness, and the status of the surgical margins. Conclusion. Tumour diameter is not the most accurate when compared to tumour thickness or depth of invasion, which can be related directly to prognosis. There is a wide agreement on using ultrasound guided fine needle aspiration biopsies in the evaluation of lymph node metastasis.

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.

Introduction: “Oral squamous cell carcinoma (OSCC)” is a major health issue in India, the incidence of OSCC is 3-7 times more in developing countries than developed countries. OSCC is the ‘3rd most common cancer’ in India followed by “cervical and breast cancer”. One side  of OSCC that  has not much explore is the ‘microinvasive squamous cell carcinoma’ which is an early stage neoplasm  without infiltration in the deeper tissues. There is no particular definition of “microinvasive oral squamous cell carcinoma (MIOSCC)” There are no specific guideline are present to categories the “microinvasive squamous cell carcinoma (MIOSCC)”. Most of the time the infiltrating neoplastic cells are masked under the background of the inflammatory cell infiltrate present connective tissue stroma. So this study is humble attempt to recognized and measured depth of invasion of infiltrative neoplastic cells to categories MIOSCC and to find better management protocol for it Aim: This study aims to: Measure p53 immunoexpression  in “microinvasive oral squamous cell carcinoma, evaluate the depth of invasion in MIOSCC  in H & E stained section, and correlate the  p53 immunoexpression with  the depth of tumor in it. Methodology: The  25 cases of  “microinvasive oral squamous cell carcinoma” will be selected  and 10 cases of “normal oral mucosa (NOM)” will be   obtained from “gingiva and vestibular mucosa” as controls  after extraction of impacted teeth. “The depth of tumor”  will  be measured from the “basement membrane or in areas of basement membrane loss, from an imaginary line reconstructing the basement membrane from the adjacent epithelium to the deepest point of invasion in connective tissue” by  Leica DMLB2 research microscope with Leica Q-win standard software (Switzerland). Results: The results  show that   the depth of invasion in MIOSCC, will be  categorized the lesion and give the better guidelines for histological grading and treatment protocol for MIOSCC Conclusion: There are no definite guidelines for histological grading and final treatment protocol for MIOSCC. The assessments of depth of tumor through p53 immunoexpression may be one of the criteria for grading in MIOSCC. Thus the correlation of p53 immunoexpression with the depth of tumor in MIOSCC helps to determine the treatment modalities of MIOSCC.

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.
