Abstract:
OBJECTIVE To observe the submucosal infiltrating extent of laryngeal carcinoma tissue by different location,different T staging and external appearance and to analyze the impact of laryngeal carcinoma submucosal infiltrating extent on surgical margin.METHODS Forty-three laryngeal en bloc specimens coming from 43 cases with laryngeal carcinoma were vertically cut-down along tumor long axis,and were slivered into sections by which laryngeal carcinoma submucosal infiltrating distance was measured under microscope.Laryngeal carcinoma latent submucosal infiltrating extent was compared among different location,different T staging and external appearance.RESULTS Basing on tumor external appearance and infiltrating extent,laryngeal carcinoma was classified into three types:exogenic type,ulcerating infiltrating type and mixed infiltrating type.Of 43 specimens,the three types were 10,8 and 25 cases respectively.There was a significant difference in submucosal infiltrating extent between T1～T2 and T3～T4 laryngeal carcinoma.There was also significant difference in submucosal infiltrating extent between exogenic type and ulcerating infiltrating type or mixed infiltrating type.CONCLUSION The submucosal infiltrating extent of laryngeal carcinoma tissue plays an important role in the surgical margin. As laryngeal carcinoma T stage developing,tumor submucosal infiltrating extent is becoming more extensive.Laryngeal carcinoma submucosal infiltrating extents in ulcerating infiltrating and mixed infiltrating type are more extensive than that in exogenic type.The partial laryngectomy should be prudent to be performed in cases with local advanced ulcerating infiltrating and mixed infiltrating laryngeal carcinoma.
