In the last decades, the treatment schemes for patients with locally advanced laryngeal cancer have changed significantly. These changes may have an impact in the survival of these patients. Our objective is to review the treatments administered to patients with locally advanced larynx tumors during a period of 30 years in our institution and to evaluate the prognostic impact of the changes in treatment protocols. Retrospective analysis of a cohort of 830 consecutive patients with T3 or T4 laryngeal carcinomas diagnosed and treated between 1985 and 2014 with a minimum follow-up of 1.5 years. During the study period, we witnessed a reduction in surgery as the initial treatment, as well as a substitution of induction chemotherapy by chemoradiotherapy as an organ preservation strategy. For patients with T3 tumors, there were no differences in cancer-specific survival by type of treatment, while patients with T4 tumors treated surgically showed significantly better survival than those treated with preservation strategies. Patients treated in the last decade (2005–2014) showed worse cancer-specific survival than those treated in the previous decade (1995–2004). The multivariate analysis showed significant differences in cancer-specific survival for larger tumors, positive nodal extension, and treatment with radiotherapy alone. The main changes in the management of advanced laryngeal carcinomas are the implementation of organ preservation strategies that reduce the use of surgery and the progressive of chemoradiotherapy as a standard treatment. These changes may have had a negative impact in survival of these patients.
