Oral Squamous Cell Carcinoma: A Clinicopathological Study of 342 Thai Cases

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.

Squamous cell carcinoma characterized by poor prognosis due to aggressive tumor growth and dissemination high rate of tumor cell . age ranged of patient case included in the study 40-62 years and mean age 55±99. The sex distribution male/female ratio 1:1. Male case 15 and female 15 of the present study The results of clinical forums showed in the current study was endophytic 10(33.3%) in the same time Exophytic were presented in 20 cases (76.7%). Regarding distribution of the tumors site, the preponderance of them 19 cases 73.3% were located alveolar mucosa, followed by in the tongue 11 cases(36.7%) Tumor stage was analyzed and recorded in Oral squamous cell carcinoma included cases, the preponderance of them were Stage II 11 cases 36.7% followed by stage III 10 cases 33.3% , 9 cases 30.0% were stage I. While Concerning tumor grade, majority of them 15 cases 50% had grade II moderately differentiated SCC, while 11 cases 36.7% had grade III poorly differentiated SCC and 4 cases 13.3% had grade I well differentiated SCC Positive TGF-β3 immunostaining was detected as cell with staining brown color, all tissues sections included show Positive expression based on IHC teqnique. Positive Transforming Growth Factor TGF-β3 Immuno staining was found in all case results and display that 4 samples with percentage 13.3% expressed strong positive 87.67 ± 1.45 expression , 11cases 36.7% showed 51.33 ±0.88 positive expression moderate at the same time 15 samples 50.0% showed positive weak expression.
