Abstract Aim To conduct a clinicopathological review of oral squamous cell carcinoma (SCC) and to analyze it with respect to gender, age at diagnosis, clinical presentation, lesion location, and histological grading. Methods and Materials Information on the clinicopathological characteristics of SCC was obtained from pathology reports of 342 cases. Results The male to female ratio was 1:1 and the incidence increased with age. Among the patients 4.7% were younger than 40 years and males were predominant in this subgroup. The alveolar ridge and gingiva were the most commonly affected sites (50%). The majority of the SCC cases presented as ulcers or masses. Swelling and/or pain were the first signs and/ or symptoms in most patients (52.6%). The age at diagnosis in relation to the site of occurrence varied. Conventional SCC was the most common subtype (88%). Well-differentiated SCC was the most common histological grading (78.6%). Conclusion In the present study, the incidence of SCC was age-related and showed equal gender distribution. Clinical Significance Routine examination of the oral cavity by dental practitioners and other health care providers aids in the early detection of premalignant and malignant oral disease. Dentists can play a significant role in disseminating information regarding oral cancer. Citation Jainkittivong A, Swasdison S, Thangpisityotin M, Lnaglais RP.

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 Aim The aim of the study was to evaluate the proliferative index (PI) at their invasive front of oral cancer and their association with Bryne's grades of oral squamous cell carcinoma (OSCC) and compare the PI with lymph node metastasis, site of involvement, and habits. Materials and methods The Ki-67 antigen expression was immunohistochemically evaluated in a total of 102 cases that included the histopathologically diagnosed archival specimens of OSCCs. They were subdivided by Bryne's histopathological grading into grade I (40 cases), grade II (32 cases), and grade III (30 cases). The nucleus with brown stain was considered positive. Cells were counted under 400× magnification. The proliferative activity thus determined was then expressed as a percentage of Ki-67 labeling index (Ki-67 LI) positive cells. Results A stepwise increase in the mean Ki-67 LI was found from grade I to III squamous cell carcinoma, thus correlating with the histological grading. In addition, there was a higher PI seen in cases associated with metastatic lymph node, which concords with the higher biologic aggressiveness and poor prognosis of the lesion. Conclusion The present study shows a definitive correlation of Ki-67 antigen with the Bryne's histological grading, all the parameters of Bryne's grading for OSCC and lymph node status of the patient proving its association as an effective tool to grade the tumors and finally read the prognosis of the tumor. Clinical significance Cell proliferation is regarded as one of the most important biologic mechanisms in oncogenesis. The role of cell proliferation in tumor progression has been inferred in studies concerned with human cancer by comparing the PI of normal tissue, preneoplastic and neoplastic lesions. The Ki-67 antigen-labeled cells can prove to be an effective aid to grade the tumors. It might be possible to standardize and objectify tumor grading among pathology laboratories.
