Abstract:
Objective To investigate the number and level of occult neck lymphatic metastasis for squamous cell carcinoma of tongue in clinical stage Ⅰ / Ⅱ,and the relationship between cell differentiation and occult neck lymphatic metastasis.Methods A total of 101 cases diagnosed preoperatively as having squamous cell carcinoma of tongue in clinical stage Ⅰ / Ⅱ (cT1/T2N0M0) between January 2005 and April 2015 were analysed retrospectively.Whether presence of occult neck lymphatic metastasis in these cases was studied.Results Occult neck lymphatic metastases were found in 22 (21.78％) of 101 cases,10 men and 12 women,with an age range of 22 to 83 years.There was not statistically significant association between tumor size or cell differentiation and occult neck lymphatic metastasis (P ＞ 0.05).The metastasis occurred most commonly in level Ⅱ,followed by levels Ⅰ,Ⅲ and Ⅳ.There was no lymph node metastasis in Level Ⅴ.There were total 20 cases with occult neck lymphatic metastasis in at least one of level Ⅰ,Ⅱ,Ⅲ (90.9％),One of these case was skipping metastasis in level Ⅲ (4.6％).Conclusion The early tongue cancer has a high rate of occult lymph metastasis,which occurs commonly in levels Ⅱ,Ⅰ and Ⅲ,but there is not significant association between the metastasis and tumor size or cell differentiation.
