Seven cases of delayed airway stenosis after radiotherapy for early staged head and neck cancers during 1989 and 1999 were evaluated (aged 54-77yrs, 6 male and a female). The cases included five glottic laryngeal cancers (T1a, T1b, and three T2), a subglottic laryngeal cancer, and an unknown origin, but strongly suspected laryngeal cancer, with neck metastasis. Radio injury was found from 3 months to 47 months after radiotherapy. 60Co for radiotherapy was used in all seven cases, although 60Co radionuclide was changed to Liniac in 1997. The total dose was 60Gy for 3 cases, and 70Gy for 4 cases. Tracheostomy was performed in 3 cases due to bilateral vocal cord impairment. Background, treatment, and response to radiotherapy were compared to those of 90 patients of a control group with early staged laryngeal cancer who did not fail radiation injury during the same period. As a result, radionuclide (60Co), total dose, cervical surgery, antiinflammatory drugs, laryngeal edema during radiotherapy were risk factors. The intensity and the period of mucositis by radiotherapy was important for indicating delayed airway stenosis.
