Management and Oncologic Outcomes of Close and Positive Margins after Transoral CO₂ Laser Microsurgery for Early Glottic Carcinoma.

ABSTRACT:

Background

The present study analyzed the impact of margin status on local control and survival, and the management of close/positive margins after transoral CO₂ laser microsurgery for early glottic carcinoma.

Methods

351 patients (328 males, 23 females, mean age 65.6 years) underwent surgery. We identified the following margin statuses: negative, close superficial (CS), close deep (CD), positive single superficial (SS), positive multiple superficial (MS), and positive deep (DEEP).

Results

A total of 286 patients (81.5%) had negative margins, 23 (6.5%) had close margins (8 CS, 15 CD) and 42 (12%) had positive margins (16 SS, 9 MS, 17 DEEP). Among the 65 patients with close/positive margins, 44 patients underwent enlargement, 6 radiotherapy and 15 follow-up.
