OBJECTIVE: To investigate the risk factors in the prediction of cervical lymph node metastases and the cervical lymph node prognostic factors in supraglottic laryngeal carcinoma.
METHOD: A retrospective study was carried out to review the histopathological data from 55 supraglottic laryngeal carcinoma patients. The relationship between histopathological parameters and cervical lymph node metastases were evaluated by means of a univariate chi2 test and multivariate stepwise logistic regression model. And the Cox regression model was used to define possible pathological parameters of cervical lymph node affecting survival including N staging, presence of cervical lymph node metastases and extracapsular nodal spread, size and number of positive neck nodes, and levels of positive neck nodes.
RESULT: In a univariate analysis, it was confirmed that the following variables correlated to cervical lymph node metastases, i.e., depth of primary tumor infiltration, size and histological grade of primary tumor. In a multivariate analysis, the most significant risk factors for cervical lymph node metastases were the size and histological grade of primary tumor. The overall 5-year survival rate of patients with supraglottic laryngeal carcinoma was 52.7%. In a Cox regression analysis, N staging, size of positive neck nodes, presence of cervical lymph node metastasis and extracapsular nodal spread were found to be related to the prognosis of supraglottic laryngeal carcinoma.
CONCLUSION: Cervical lymph node metastasis is one of the most significant prognostic factors of supraglottic laryngeal carcinoma. The identification of patients at risk for cervical lymph node metastasis and the management of the neck by coping with pathological factors of neck node affecting survival are crucial steps to improve the effect of supraglottic laryngeal carcinoma treatment.
