Patients and Methods: Sixty-three consecutive patients, treated with definitive RT between 1999 and 2005, were retrospectively analyzed. All patients had histologically proven squamous cell carcinomas of the larynx. The median age was 62 years (range 43-83 years). Follow-up ranged from 22 days to 68 months (median 32 months). Results: The LRC rates at 2 and 5 years were 70% and 48%. The 2- and 5-year OS rates were 65% and 40%. No statistically significant relationship was found between World Health Organization performance status score (WHO PS) and age (p = .21), tumour site (p = .42), overall stage (p = .11), T stage (p = .19), and N stage (p = .69). Multivariate analyses showed that a WHO PS score >= 2 (p < .0001) and RT treatment time >= 50 days (p = .0172) significantly decreased LRC. Moreover, a WHO PS score >= 2 (p < .0001), RT treatment time >= 50 days (p = .0138), and RT dose < 66 Gy (p = .04) were significantly negative prognostic factors on OS. Conclusion: Definitive RT, in patients with early- and more advanced-stage squamous cell carcinoma of the larynx, is an important treatment option. It is clear that patients with good pretreatment PS would get better results from definitive RT.en10.2310/7070.2008.OA0173info:eu-repo/semantics/closedAccessCarcinomaLarynxPerformance StatusPrognostic FactorsRadiotherapyArticle376799806Q4WOS:0002074635000202-s2.0-6434912367819128707Q1
