Although definitive chemoradiation (CRT) has been used for locally advanced laryngeal cancer for more than 2 decades, studies focusing on CRT failures in advanced laryngeal cancer are scarce. In this study, we aimed to determine the failure patterns and the survival outcomes in the patients who had recurrence after concurrent CRT for laryngeal cancer. Clinical records of the patients who had definitive concurrent CRT for laryngeal cancer between 2001 and 2014 at a tertiary referral center were reviewed. The end points of the study were 1-, 2-, and 3-year overall survival (OS) and disease-specific survival (DSS). In our results, there were 48 failures and the mean time period from the first diagnosis of disease to the diagnosis of recurrence was 18.0 months (range 2-72; standard deviation: 15.6). The most common recurrence pattern was local recurrence in 21 (47.9%) patients followed by regional recurrence in 11 (22.9%) patients. The 1 and 3 years OS rates were 41.7%, and 19.2% for the entire cohort, and 64.5%, and 29.7% for the patients who had not systemic recurrence at presentation of recurrence, respectively. The 1 and 3 years DSS rates were 43.5%, and 20.0% for the entire cohort, and 69.0%, and 31.8% for the patients who had not systemic recurrence at presentation of recurrence, respectively. All patients who had systemic recurrence initially (n = 13) died within 9 months (median = 4 months, range: 1-9 months). This study reveals that survival outcomes are unfavorable in the CRT failures and careful patient selection is critical to minimize failures. In the presence of systemic recurrence, disease course is aggressive.
