Relationship between Neck Lymph Nodes Biopsy and Prognosis in Nasopharyngeal Cancer

Objective To reasearch the influence of neck lymph node biopsy on the prognosis for NPC. Methods The data of 39 cases with NPC diagnosed by neck lymph node biopsy and nasopharyngeal biopsy and of 39 cases by nasopharyngeal biopsy were reviewed to compare the rate of distant metastasis,neck receurrence and 3 year survial rates. Results The rates of distant metastasis were 53.8%(21/39) in neck lymph node biospy group,compared to 25.6%(10/39) in nasopharymgeal biospy group ( P=0.0074 );the rates of neck recurr...
