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.
