目前,临床上诊治喉癌的难点仍在于术前无法确定喉癌在粘膜下生长传播的真正范围,只能凭临床诊察及手术所见作估计,经术后连续切片的病理学检验,临床分期不正确率高达55%(国外资料报告为40%),原因在于临床医生对喉癌在粘膜下广泛浸润估计不足。近年来,我们对喉癌术后标本做了大块连续切片观察,从喉癌传播的病理学研究探讨了喉内“屏障”的作用,为手术者
At present, the difficulty in clinical diagnosis and treatment of laryngeal cancer still lies in the fact that the true extent of submucosal growth and propagation of laryngeal cancer cannot be determined before surgery. It can only be estimated by clinical examinations and surgical findings. Pathological examination of consecutive slices after staging, clinical staging The inaccuracy rate is as high as 55% (foreign data reported as 40%), because the clinician underestimates the extensive submucosal infiltration of laryngeal cancer. In recent years, we have performed continuous section observations on laryngeal cancer specimens, and explored the role of “barriers” in the laryngeal stenosis from the pathological study of the spread of laryngeal cancer.
