Preservación de órgano en pacientes con tumores avanzados de laringe. Resultados de la quimioterapia de inducción versus quimio-radioterapia en la práctica clínica real

Abstract

Introduction and objectivesA high percentage of patients with locally advanced larynx carcinomas are candidates for inclusion in organ preservation protocols. The objective of this study is to compare the results of two schemes of preservation, induction chemotherapy versus chemoradiotherapy, in patients with locally advanced larynx carcinomas in the context of actual clinical practice. MethodsOur retrospective study included 157 patients with locally advanced tumours of the larynx (T3-T4) treated with induction chemotherapy (n = 121) or chemoradiotherapy (n = 36). ResultsFrom 121 patients who began treatment with induction chemotherapy, 6 died due to toxicity, 37 were treated with surgery, and 78 completed the preservation scheme; 36 patients received treatment with chemoradiotherapy. There were no significant differences in 5-year disease-specific survival between both treatments: 68.9% in induction chemotherapy versus 75.7% in chemoradiotherapy (p = 0.259). In 45.9% of patients the laryngeal function was preserved. Patients treated with chemoradiotherapy had a tendency to have better 5-year laryngeal dysfunction-free survival than patients treated with induction chemotherapy (55.6% versus 44.8%, p = 0.079). ConclusionPatients included in a protocol of organ preservation achieved a 5-year laryngeal dysfunction-free survival of 45.9%. There were no significant differences in disease-specific survival among patients treated with induction chemotherapy or chemoradiotherapy.
