The positive rate of MTA1 expression was significantly higher in NPC and metastatic lymph node tissues than chronic nasopharyngitis tissues, and the expression level of MTA1 mRNA correlated positively with lymph node metastasis, tumor recurrence and death; however, the prognostic significance of MTA1 was not investigated [24]. The gene discussed is MTA1; the disease is metastatic malignant neoplasm in the lymph nodes.
