Organ preservation in ORL oncology: myth or reality. The case for laryngeal preservation

摘要

The conservation of a functional larynx is an important goal in the various attempts to improve the treatment of locally-advanced pharyngo-laryngeal cancers. Several axes have been followed: conservative surgery (subtotal laryngectomy), exclusive irradiation (with conventional or non-conventional fractionation), initial chemotherapy (followed by surgery or irradiation) or concomitant chemotherapy-radiotherapy. The numerous studies, including some major randomised trials, dealing with the issue of larynx preservation are reviewed in the present article. A critical comparison of their results and its integration in a consistent approach are difficult, especially because the different options are aimed at different patients. Total laryngectomy and its psychological and social consequences can be avoided in a significant number of patients, although the long term functional outcome is poorly known and the choice of the optimal treatment modality is largely dependent on the expertise and experience of the medical team.
