Clinical study of oral squamous cell carcinoma with clinically lymph node-negative / 实用口腔医学杂志

ABSTRACT

Objective:To investigate the clinical and pathological factors of metastasis in patients with oral squamous cell carcinoma (OSCC)and clinical lymph node-negative(cN0).Methods:85 patients of OSCC with cN0 treated in 2008-07 -2013-07 were inves-tigated retrospectively.Results:In the 85 patients 24(28.34%)showed occult metastasis.Patient's gender,lesion location had no im-pact to metastasis(P >0.05),the patient's age,tumor size,growth pattern and histopathologic grade showed significant influence on the metastasis of OSCC(P <0.05).Conclusion:The greater tumor volume,lower differentiation degree and young age are the factors of higher occult lymph node metastasis.Selective neck dissection treatments of OSCC is recommended.
