Development of a new therapeutic approach to improve the prognosis of high grade invasion of oral squamous cell carcinoma is needed. To elucidate the effect of a fibroblast inhibitor (tranilast), we investigated the proliferation and metastasis of oral squamous cell carcinoma in a mouse model. The effect of tranilast on tumour growth, lymph node metastases, microvessel density, and the prolifer...
The preventive effects of the dietary administration of brown rice and rice bran fermented with Aspergillus oryzae (FBRA) on oral carcinogenesis induced by 4-nitroquinoline 1-oxide (4-NQO) were investigated in male F344 rats. At 7 weeks of age, the animals were given 20 ppm 4-NQO in their drinking water for 8 weeks to induce tongue neoplasms. Groups of rats were fed diets containing 5 or 10% FB...
Two primary tumours, squamous cell carcinoma of the tongue and multiple bronchioloalveolar carcinomas, were diagnosed in a Virginia opossum (Didelphis virginiana). Two oral masses were located in the right ventrolateral surface of the tongue, near the frenulum, and the lungs contained multiple, widely distributed, nodular masses. Microscopically, the oral masses were composed of invasive cords ...
BACKGROUND There are controversies on the benefits of elective neck dissection (END) for oral tongue carcinoma. METHOD This is a prospective randomized study of elective selective I, II, III neck dissection versus observation for N0 neck of stage I to II oral tongue carcinoma. There were 35 patients on the observation arm and 36 patients on the END arm. The main outcome assessment parameters ...
Background and Aim: Angiogenesis plays a central role for development and progression of malignant tumors.It is considered as an important factor for predicting of malignant tumor's behavior such as metastasis to lymph nodes and other clinicopathologic factors. However , it is still a controversial factor especially in oral squamous cell carcinoma.The aim of this study was to evaluate the corre...
BACKGROUND The incidence of oral cancers varies from one country to another, which can be clarified by the difference in the distribution of the risk factors and the possible etiologies. Tongue is a main segment of oral cavity and malignant lesions of this region accounts for nearly 30% of all oral cancers. OBJECTIVES In the present study, we evaluated the pattern of tongue cancer in Iranian ...
BACKGROUND We previously reported the utility of preoperative nuclear morphometry for evaluating risk for cervical lymph node metastases in tongue squamous cell carcinoma. The risk for lymph node metastasis in oral squamous cell carcinoma, however, is known to differ depending on the anatomical site of the primary tumor, such as the tongue, gingiva, mouth floor, and buccal mucosa. In this study...
BACKGROUND AND AIM: Epidemiological studies have established a wide variation in the prevalence of oral lesions in different population. Officially oral mucosa diseases can occur in 25-50% of cases, depending on the population to which the survey was conducted. We examined the relationship between oral mucosal lesions, tongue pH level, gingivitis, oral hygiene, and oral health behaviors in stud...
BACKGROUND & OBJECTIVE Patients with advanced squamous cell carcinoma (SCC) of the oral tongue have poor prognosis. This study was to analyze the most important factors affecting the prognosis of the patients with advanced (stage III and IV) SCC of the oral tongue. METHODS Complete clinical and follow-up data of 229 patients with pathologically confirmed advanced SCC of the oral tongue, initi...
Oral cancer is considered a great threat to public health. Tongue cancer accounts for nearly 30% of all oral cancers and usually seen in 50 to 60 year old men. Oropharyngeal cancers account for 3% of all cancers in Iran; as reported in 2003. The present study was designed to assess the epidemiologic and clinicopathologic characteristics of tongue cancer patients in two Tehran's referral univers...
