title: Laryngeal carcinoma: five-year survival and patterns of failure in 202 consecutive patients treated with primary or post-operative radiotherapy in Hong Kong.
abstract: OBJECTIVE
  We aimed to conduct a retrospective analysis of patients treated with radiotherapy for laryngeal carcinoma at a single institution.
  
  
  METHODS
  We analysed data from 202 consecutive patients treated with primary or post-operative radiotherapy for laryngeal carcinoma over a 10-year period.
  
  
  RESULTS
  Sixty-nine patients had a T1, 65 a T2, 39 a T3 and 29 a T4 lesion. Forty-one patients were node-positive. The clinical stage was I in 67 patients, II in 53, III in 36 and IV in 46. Primary radiotherapy was given to 152 patients. The median follow up was 60 months. The five-year overall local control rate was 86 per cent, the ultimate local control rate was 93 per cent, the five-year regional control rate was 96 per cent, the five-year relapse-free survival rate was 82 per cent and the five-year overall survival rate was 69 per cent.
  
  
  CONCLUSIONS
  Patients with laryngeal carcinoma treated with primary or post-operative radiotherapy had a five-year overall survival rate of 69 per cent.
