RESUMEN
OBJECTIVE@#The aim of this study is to investigate the expression and clinical significance of 6-phosphofructo-1-kinase in nasopharyngeal carcinoma biopsy samples.@*METHOD@#Sixty-one biopsy samples were detected, including 41 tissues samples from patients with nasopharyngeal carcinoma and 20 tissues samples from patients with chronic nasopharyngitis as control group. 6-phosphofructo 1 kinase mRNA expression was detected by RTPCR.@*RESULT@#It was observed that the expression levels of 6 phosphofructo-1-kinase mRNA in nasopharyngeal carcinoma tissues were higher than in the chronic inflammatory tissues. And the expression levels in patients with lymph node metastasis were higher than without lymph nod metastasis.@*CONCLUSION@#6-phosphofructo-1-kinase may be a marker in occurrence and metastasis of nasopharyngeal carcinoma.
