[Histopathological study of surgical resection margins of laryngeal carcinoma].
64 specimens of laryngeal carcinoma were studied by using the step-serial whole organ section and histopathologic examination of the region around tumor. We discussed the situation of lesions spreading from tumor to resection margins, the survival rate of different types of resection margins, the common position of positive resection margins and the correlative factors of positive resection margins combining with histopathology, clinical expression and follow-up results. We concluded that resection margins more than 5 mm far from visible tumor is suitable.
