[Larynx preservation: nonsurgical approaches].
The question of larynx preservation is central in the management of patients with a carcinoma of the larynx or hypopharynx, especially to preserve the main functions of the larynx. In early stages (T1-earlyT2) Larynx preservation can generally be obtained with partial surgery or radiotherapy. Some other approaches such as exclusive chemotherapy require further investigations. In locally advanced and infiltrating larynx/hypopharynx carcinomas, (advancedT2-T3), several ways have been used to preserve the larynx including exclusive radiotherapy which can be improved by modified fractionation and acceleration. The efficacy of radiotherapy can be also markedly increased by adding concomitant cisplatin based chemotherapy, as reported recently in a large randomized trial. An alternative approach consisted in using induction chemotherapy (cisplatin-5FU) and followed by a local treatment adapted to the response to chemotherapy. The combined analysis of 3 such randomized trials (GETTEC, Veteran et EORTC) showed that this approach has to be used with caution, and could be safer in good responders to induction chemotherapy. Finally, larynx preservation is generally not proposed in patients with deeply infiltrating tumors and or tumor invading the cartilage or soft tissue in the neck (T4).
