[Analysis of negative cordectomy specimens using CO2 laser for T1 glottic cancer].

OBJECTIVE

This study determined presence or absence of residual cancer in the surgical specimen and analyzed outcomes.

METHOD: A retrospective study of 57 patients with glottic carcinoma (7 Tis, 47 T1a, and 3 T1b) treated from January 2000 to February 2010. All histological slides from the 57 patients were re-examined under the light microscope by the pathologist and the surgeon. We performed multiple biopsies and intraoperative biopsy as a diagnostic procedure.

RESULT: There were 5, 4, 41, 3, and 4 types I to V cordectomies, respectively. 6 negative cordectomies (10.5%) were reported.

CONCLUSION

The endoscopic treatment of T1 glottic cancer should be as conservative as possible. This assures resection of all the malignant tissue and preserves the maximum amount of healthy tissue.
