[A clinical study of 213 patients with laryngeal cancer]

We retrospectively analyzed 213 patients--197 men and 14 women aged 40 to 87 years--with laryngeal cancer treated at our department from September 1986 to December 1997. The male to female ratio was about 12:1. Cases included 120 glottic (56.3%), 90 supraglottic (42.3%), and 3 subglottic (1.4%). Radiotherapy for early cases and surgery, mainly total laryngectomy for T3 and T4 were conducted first. The 5-year cause-specific survival by site was 97.6% glottic and 77.5% supraglottic. The five-year survival was 88.6% overall. Local control was 83.8% in glottic T1a and 84.6% in glottic T1b. The 3-year preservation of the larynx was 89.1% in glottic T1a and 92.3% in glottic T1b. Distant metastases were observed in 14 cases, mostly to the lung, bones, and liver. At high risk for distant metastasis were those with supraglottic T3-T4, N1, N2b, or pN2c.
