Clinical value of serum Epstein-Barr virus DNA assay in the diagnosis of nasopharyngeal carcinoma.

Serum Epstein-Barr virus DNA has been approved for diagnosing nasopharyngeal carcinoma (NPC). The goal of this meta-analysis was to evaluate the clinical value of the serum Epstein-Barr virus DNA in the diagnosis of NPC. The PubMed, Embase, Web of Knowledge, Chinese Wanfang Med Online, and National Knowledge Infrastructure (CNKI) databases were searched to identify suitable studies.

[Correlation between the expression of HER-2/neu, nm23 protein and local invasion and lymph node metastasis of human LSCC].

Objective: To explore the relationship between the expressions of HER-2/neu, nm23 protein and local invasion and lymp node metastasis of LSCC.

Method: The expression of HER-2/neu, nm23 protein was detected by immunohistochemical technique in 56 patients with human LSCC.

Result: The positive expression rate of HER-2/neu protein in LSCC was not correlated with histological grade (P > 0.
