[CO2 laser surgery for the treatment of vocal cord carcinomas in early stages (T1 T2)].
BACKGROUND
The standard treatment for patients with early vocal cord carcinoma has been radiotherapy. In recent years, encouraging results with CO2 laser surgery has changed our treatment strategy in selective cases. During the past four years at the Rabin Medical Center we have treated patients with carcinoma of the vocal cord using CO2 laser surgery.


OBJECTIVE
We conducted a retrospective study to investigate the results of the Head and Neck Surgery department with CO2 laser treatment for squamous cell carcinoma of the vocal cord during early stages (T1, T2) without radiotherapy.


METHODS
Twenty one patients with carcinoma of the vocal cords in early stages were treated with CO2 laser. Nineteen patients suffered from stage T1 carcinoma located in one vocal cord, three of these patients suffered from involvement of the anterior commissure and one patient also had involvement with the anterior part of the second vocal cord. Two patients with carcinoma in stage T2, one with involvement of the ventricular band and one with limited movement of the vocal cord. The follow-up period for the patients ranged from one month to four years.


RESULTS
Only one patient in stage T1 developed local recurrence after half a year, no patients died during the follow-up.


CONCLUSIONS
Careful patient selection with endoscopic staging also during the biopsy, removal of the carcinoma in free border, strict follow-up and stroboscopic examination are essential to secure good results in the treatment of CO2 laser for early stages of vocal cord carcinoma.
