Abstract:
Objective:To study the direction of cervical node extracapsular spread(ECS)of oral squamous cell carcinoma(OSCC). Methods:57 cases of OSCC were treated by combined radical operation.The relationship between ECS and T stage,tumor thick-ness,differentiation degree of OSCC,lymph node size and the ECS direction in each lymph node level were statistically analysed. Results:ECS was found in 30 of the 57 cases,and in 78 of the 174 metastasis positive lymph nodes.29 ECS nodes in levelⅠ,the frequency of the shallow side was 26,the deep side 13(P=0.000 3).But the difference in other levels was not statistically signifi-cant(P>0.05).It was not statistically significant between the incidence of ECS and T stage;it was statistically significant between the incidence of ECS and tumor thickness(P<0.05),tumor differentiation degree(P<0.05)and the lymph node size(P<0.01). Conclusion:ECS of OSCC on the shallow side is more than that in the deep side of lymph nodes in levelⅠ.ECS is positively corre-lated with the tumor thickness of OSCC,metastasied lymph node size;negatively related to the differentiation degree of OSCC.
