Epithelial Tumors and EBV

EBV is also related to a series of epithelial malignan-cies.[9] Of these, nasopharyngeal carcinoma (NPC) is the most prevalent tumor in Southeast Asia and is endemic in Southern China and Hong Kong (9 per 100,000), in Northern Africa, and among the Inuits. According to the differentiation of the tumor tissue, NPC is classified into three subtypes: ''squamous,'' ''nonkeratinizing,'' and ''undifferentiated'' NPC. The undifferentiated type of NPC is virtually always associated with EBV. Besides EBV, both the genetic background and diet are cofactors for the development of NPC.

Tumors of the glandular epithelium of the stomach, the salivary gland, the lung, and the thymus are other EBV-related lymphoepithelial tumors. EBV can be detected in 75-100% of the rare lymphoepithelioma-like gastric carcinomas and in approximately 27-35% of gastric stump carcinomas. In addition, EBV is detected in 2-16% of gastric adenocarcinomas.

Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
