| Abstract;Eight patients with recurrent glottic rT1 carcinoma after radiotherapy were treated with a laser via laryngomicrosurgery. T classification at radiotherapy was one case of T1a, three cases of T1b, three cases of T2, and one unknown case. The period between radiotherapy and recurrence was 7 months to 7 years (mean 25 months). T classification at recurrence was five cases of rT1a and three cases of rT1b. Laser surgery was performed under general anesthesia, and the recurrent tumor was vaporized and excised by laser irradiation. The tumor was controlled by laser surgery in five of eight cases, and no recurrence occurred for between 19 and 97 months (mean 4 years). In the other three cases, total laryngectomy was required due to residual tumor after laser surgery, and one patient died of neck metastasis. The larynx preservation rate was 63% (5/8), and the survival rate was 88% (7/8). A frontoneck subcutaneous abcess occurred in one case as a complication of laser surgery, and it disappeared with medication treatment. No other complications were noted. We concluded that glottic rT1 carcinoma after radiotherapy is an indication for laser surgery. (author abst.) |
