Preliminary Study On The Partial Glossectomy Of CT1N0M0Squamous Cell Carcinoma Of Tongue

Objective:This report analyzes the results of the treatment when patients are allocated to observation of the neck, to evaluate the clinical effect of partial glossectomy of early tongue carcinoma,and provide clinical treatment the rational scheme.Materials and methods:We reviewed52patients who are allocated to observation of the neck,treatmented by central south university the second xiangya hospital,between2007-2011.Results:Metastatic squmous cell carcinomaof tongue was identified in10of52patients.there was1local recurrence,and1recurred in tongue and metastasized to neck.The rate of occult cervical node metastases in52patients was21.6%.The most common region with metastases was level I-III.The rate of occult cervical lymph node metastases was statistically correlated with the depth of invasion,pathology location(p<0.05). While age,sex,pathological grade and precancerosis had no significant correlation with occult cervical lymph node metastases.Conclusion:1.The rate of local recurrences in eT1N0M0patients was3.8%,and the rate of occult cervical lymph node metastases was21.6%. Occult cervical lymph node metastases was statistically signifycantly correlated with the tumor sites. The most common regions with cervical lymph node in cT1N0M0patients with squamous cell carcinoma of the tongue were levels Ⅰ-Ⅲ.2.Occult cervical lymph node metastases was statistically significantly correlated with the depth of invasion.3.It’s meaningful to perform only partial glossectomy in patients of early tongue squamous cell carcinoma.
