OBJECTIVE To determine the frequency of submandibular gland involvement in early oral cavity tumors. STUDY DESIGN Observational study. PLACE AND DURATION OF STUDY ENT Department, CMH, Rawalpindi, from January 2008 to December 2011. METHODOLOGY Data of 110 oral cavity tumors operated over 2008 - 2011 was retrieved from ENT OPD, tumor registry in AFIP and from Head and Neck Oncology Forum R...

Metastatic tumors account for 1% of all oral malignancies. Metastasis to jaw bones is common, particularly in the mandible, rare in the oral soft tissues, and account for only 0.1% of oral malignancies. The majority of metastatic cases (70%) reported in the literature have primary tumors located in the lung, breast, kidney, and colon. Metastasis is a biological complex process that involves det...

Cancer is a complex disease that involves the accumulation of both genetic and epigenetic alterations of numerous genes. Data in the Genetic Alterations in Cancer database for gene mutations and allelic loss [loss of heterozygosity (LOH)] in human tumors (e.g. lung, oral, esophagus, stomach and colon/rectum) were reviewed. Results for the genes and pathways implicated in tumor development at th...

Oral cancer is characterized by high morbidity and mortality with a predisposition to metastasize to different tissues, including lung, liver, and bone. Despite progress in the understanding of mutational profiles and deregulated pathways in oral cancer, patient survival has not significantly improved over the past decades. Therefore, there is a need to establish in vivo models that recapitulat...

Many types of cancers develop in the oral and maxillofacial region. Squamous cell carcinoma is the most common cancer and constitutes over 90 percent of these tumors. Malignant transformation is a genetic process, which later makes a phenotyping change at the cellular level. Some cancers such as oral squamous cell carcinomas (OSCCs) develop from pre-malignant lesions and conditions. Despite adv...
