VoiceS: Voice Quality After Transoral CO2-Laser Surgery Versus Single Vocal Cord Irradiation for Larynx Cancer

The following planning aim will be pursued: full coverage of the PTV with at least 95% of the prescribed dose and a maximum (0.03 cc) PTV dose of \<107%: 16 x 3.63 = 58.08 Gy in 5 fractions per week using 5 to 9 static IMRT or VMAT.

"The TLM has to be performed using a CO2 laser, coupled to an operative microscope, at 4-8W in ultrapulse mode. The type of cordectomy performed must be mentioned using the following classification according the classification of the European Laryngological Society.~The type of resection chosen should provide complete removal of the primary lesion with negative margins.~Surgery will generally be performed within 3 weeks after randomization and not more than 6 weeks after panendoscopy.~The extent of the cordectomy must include a complete anterior, posterior, inferior and supero-lateral mucosal and deep soft tissue margin."
