Treatment Results of Early Laryngeal Carcinoma

On 147 patients with early laryngeal cancer undertaken surgery or radiation therapy at Seoul National University Hospital from January 1987 through December 1994, retrospective analysis with reviewing the medical record was performed. The number of recurred cases was twenty six. The recurrence rate was higher in the cases with radiation therapy than in those with surgical therapy. And the recurrence rate was remarkable in the cases with T2 in supraglottic cancer and in those with T1 in glottic cancer. Of the patients undertaken surgery, recurrence rate was higher in the patients with laser operation than in those with other procedures. It was, however, lower in the patients with laryngofissure with cordectomy than in those with other surgical techniques. The overall three year disease free survival rate was 72 % in early laryngeal carcinoma.
