[Preliminary study on the correlation factors of cervical lymphatic metastasis of glottic carcinoma].
OBJECTIVE
To investigate the incidence of occult nodal in glottic carcinoma and access the correlation between the cervical lymph nodes metastases and originals of tumor.


METHODS
A retrospective review was made on 452 patients from January 1983 to May 1998. 413 patients were male and 39 were female. The age ranged from 42 to 79 years with a mean of 59.3 years.


RESULTS
The incidence of occult nodal in glottic carcinoma was low (3.54%), and 0.29% in early stage (T1-T2), 13.39% in late stage (T3-T4), respectively. The number of metastasis lymph nodes was 7 in level II (43.75%), 7 in level III (43.75%) and 2 in level IV (12.5%).


CONCLUSIONS
According to the multivariate analysis, none of the factors such as histopathologic differentiation and invasion of peripheral tissue significantly affect on cervical metastases. The incidence of cervical lymph nodes metastases in glottic carcinoma is low. Selective neck resection should not be undertaken even for the advanced stage that don't exist metastases.
