[Transglottic carcinoma: a histopathological study of 64 cases].

Sixty-four cases of the transglottic carcinoma treated with surgical operations at our hospital were reviewed. The anatomical sites and the serial sections of the tumour specimens were observed. It indicated that 42 cases were proved to be supraglottic carcinomas; 7 glottic; 5 subglottic. Ten cases had no definite primary sites. There was no T1 lesion and only one pT2 lesion. 98.4% of the specimens showed pT3-pT4. 75% specimens lesions greater than or equal to 2 cm. Thus we suggest that the so called transglottic carcinoma should be regarded as an advanced lesion of the laryngeal cancers. The advanced cancers can spread into the paraglottic space and invade the laryngeal frame-works as a special pathological features. The paper also discussed the primary site of the transglottic lesion. We think that it is reasonable to classify the laryngeal cancers into supraglottic, glottic and subglottic categories. The idea to classify tumours that originate in the ventricle into an independent type, i.e. transglottic carcinoma, will wait for further discussions.
