Primary surgical treatment of T3 glottic carcinoma: long-term results and decision-making aspects.

OBJECTIVES/HYPOTHESIS: The aim of this study was to assess the efficacy of primary surgical treatment in the management of T3 glottic carcinomas.

STUDY

DESIGN

Retrospective clinical study.

METHODS

A retrospective evaluation of the records for all patients treated with primary surgery for T3 glottic carcinomas at a tertiary referral center between 1980 and 2005 was carried out. Data for the 5-year disease-specific survival (DSS) were assessed, as well as local control rates in relation to vocal cord immobility, N classification, choice of surgical modality, and adjuvant therapy. Patients who underwent partial laryngectomy were also evaluated in relation to organ preservation and the rate of permanent tracheotomies.

RESULTS

The 5-year DSS in the 120 patients was 78.3%. Positive neck disease was shown to be a significant negative prognostic factor. Organ preservation was achieved in 90.1% of the patients who underwent partial laryngectomy and in 50% of the overall patient group. The occult metastasis rate was 14%.

CONCLUSIONS

Primary surgical treatment is an effective modality against T3 glottic carcinomas. Partial laryngectomy is a reliable method in carefully selected cases. Low complication rates can be expected.
