ABSTRACT

Objective:To study the relation among nm23-H 1 expression,DNA contents and lymph node metastases of head and neck squamous cell carcinoma(HNSCC).Methods:Fresh specimens from 30 previously untreated patients with HNSCC were examined for the determination of nm23-H 1 expression with immunohistochemistry, Aneuploid and S-phase fraction(SPF) with flow cytometry(FCM).The association among these parameters with lymph node metastases was studied.Results: nm23-H 1 expression was found in 18 cases (60%).and aneuploid in 20 (66.7%).Correlation was found between lymph node metastasis and nm23-H 1 protein expression (P
