To clarify laryngeal cancer practices, we followed up 95 cases—92 men and 3 women with a mean age of 66.3 years between 1990 and 2003.
Supraglottic cancer was found in 26.3% (25 cases), glottic cancer in 71.6% (68), and subglottic cancer in 2.1% (2). Based on International Union Against Cancer “tumor/node/metastasis” (UICC TNM) classification, a difference exists in glottic and supraglottic distribution. Of glottic cases, 39 (57.4%) were stage I, 8 (11.8%) stage II, 10 (14.7%) stage III, and 11 (16.2%) stage IV. Of supraglottic cases, 2 (8%) were stage I, 2 (8%) stage II, 4 (16%) stage III, and 17 (68%) stage IV. Cervical lymph node metastasis was detected in 8.8% of glottic cases and 76.0% of supraglottic cases.
Overall 5-year cumulative crude survival was 74.5% and cause-specific survival 85.7%. For glottis cases, 5-year cumulative crude survival was 83.6% and cause-specific survival 92.5%. For supraglottic cases, they were 56.0% and 73.5%. For stages I-IV, 5-year cause-specific survival was 100%, 87.5%, 78.6%, and 80.0% for glottic cases and 50.0%, 50.0%, 75.0%, and 79.3% for supraglottic cases.
