Investigation of recurrence risk in laryngeal cancer following laser surgery.

BACKGROUND: The general prognostic factors in larynx tumors are believed to be tumor stage, anatomical location, histological differentiation and the presence of neck metastasis. Effects of tumor invasion to sub-regions of larynx (anterior commissure, ventricle, subglottic space) and over-expression of p53, c-erb-B2 and Ki67 detected immunohistochemically on development of recurrence in patients were investigated in this study.

METHODS: Twenty patients (Group 1) in whom recurrence had developed and 20 others (Group 2) without recurrence during follow-up were included in this study.

RESULTS: Both the anterior commissure and ventricle involvements were found to be more frequent in patients with recurrence. But statistically significant difference was detected with only ventricular involvement (p=0.025). After Immunohistochemical evaluation none of the 3 immunohistochemical parameters were found to be higher in the recurrence group and not any of them showed a statistically significant difference between two groups.

CONCLUSION: Only ventricle involvement may be a predictor factor for recurrence.
