Abstract

We investigated 107 patients who underwent total laryngectomies as treatments for T3 or T4 supraglottic carcinomas. The relationship between the clinicopathologic findings and distant metastases were examined. In postoperative follow-up, distant metastases were found in 19 patients without any evidence of locoregional recurrence. Other results were as follows : 1) There was no statistically significant correlation between varying TN categories and distant metastases. 2) There was no statistically significant correlation between the groups of carcinoma extension into the preepiglottic space. 3) In the analysis of paraglottic space (PGS) invasion, distant metastasis appeared in 15 of the 44 cases (32%) within the PGS invasion positive group and 4 of the 63 cases (6%) among the PGS invasion negative group. There was a statistically significant difference between the groups (p<1%). 4) Either an extension to the preepiglottic space or extra-capsular spread of the metastatic lymphnode resulted in 18 of 19 (95%) patients developing distant metastasis.
