BACKGROUND: To identify clinicoradiological factors that determine functional outcomes in laryngopharyngeal cancers treated with chemoradiotherapy.
METHODS: One hundred patients of locally advanced laryngopharyngeal cancers who were treated with chemoradiotherapy were accrued in this prospective study. The coprimary endpoint of the study was local control (LC) and functional larynx preservation survival (FLPS).
RESULTS: The median follow-up was 39 months. Thirty-nine patients had a local failure of which 17 underwent a salvage laryngectomy. A dysfunctional larynx with clinic-radiologically disease was seen in only 1 patient. Factors significant for LC were thyroid cartilage erosion/lysis and cricoarytenoid joint involvement. Within the T4a subset, patients with exolaryngeal disease through the soft tissue framework had significantly better LC and FLPS than those with cartilage erosion/lysis.
CONCLUSIONS: Patients with limited exolaryngeal disease through the soft-tissue framework can be considered for functional organ preservation, while those with thyroid cartilage involvement and cricoarytenoid joint involvement are not suitable.
