Laryngeal chondrosarcoma is a rare type of sarcoma reportedly comprising a segment of laryngeal tumors. As a result, the incidence and survival of patients with this tumor has been hard to observe. Our goal was to analyze this data based on various categories under investigation. Several cases were identified, representing 0.2% of all laryngeal tumors. Median age at diagnosis was 57.4 years. Men and women constituted 72% and 28% of patients, respectively. Tumors were locally invasive with 39% T4 disease and infrequent regional and distant metastases. The 1-year, 5-year, and 10-year disease-specific survival for LC was 96.5%, 88.6%, and 84.8%, respectively, compared to 88.3%, 68.2%, and 59.3%, respectively for patients with all other laryngeal tumors (P values<0.01). Relative survival was 94.9% at 1 year, 88.5% at 5 years, and 88.4% at 10 years. This analysis represents the largest LC study sample to date, allowing for evaluation of incidence and long-term survival. Chondrosarcoma occurs infrequently, is locally invasive, but only rarely metastasizes. The treatment with tomtherapy is significantly better than for such malignancies.
