There is continuing controversy surrounding the most effective treatment
of glottic carcinoma involving the anterior commissure (AC). Surgery has
been the preferred method of treatment, since studies previously indicated
early tumor invasion of the thyroid cartilage at the AC, thereby assuming
less curability by radiotherapy (RT). Subsequent laryngeal anatomic studies
and refinement of RT techniques have brought into question the ineffectiveness
of curative irradiation. A retrospective review of 174 patients with early-stage
glottic carcinoma treated with standard fractionation curative RT revealed
34 patients with TI and T2 lesions involving the AC. Allowing for a follow-up
of at least 3 years, we observed only a 12% (4 of 34 patients) local recurrence
rate after RT alone, with excellent voice quality and no major complications
related to the irradiation. The 4 local recurrences were controlled by
total laryngectomy, although 2 patients developed distant metastatic disease.
Radiotherapy represents an effective method of treating T1 squamous cell
carcinoma of the glottis with AC involvement. The small number of T2 glottic
carcinomas in this study prevents a meaningful conclusion concerning treatment
of these lesions.
