Radiotherapy plays an essential role in the function-preserving treatment of elderly patients with laryngeal cancer. Regarding early glottic cancer (GC), accelerated fractionated radiotherapy (Ax) is believed to be a useful treatment option for GC because of its convenience in reducing the treatment time, cost, and labor. In JCOG 0701, Ax showed comparable efficacy and safety to standard fractionated radiotherapy. In addition, real-world data and evidence from clinical research have also shown promising findings concerning Ax for GC. Regarding radiation techniques for advanced laryngeal cancer, intensity-modulated radiation therapy (IMRT) is very useful for reducing late toxicity, especially for concurrent chemoradiotherapy (CCRT). Less-invasive treatment using IMRT is now being evaluated in many on-going trials, and the JCOG1912 trial has just started to assess the non-inferiority in less-invasive treatment in CCRT using IMRT for locally advanced head and neck cancer. We herein report the results of our organized prospective observation study for patients using radiotherapy with cetuximab in the JROSG12-2 trial. I sincerely appreciate the opportunity to introduce our findings at the 33 rd annual meeting of the Japan Laryngological Association.

When the larynx is removed due to laryngeal or pharyngeal cancer, the vocal cords are permanently lost. An electric larynx (EL) is used as a communication device for patients after total laryngectomy. Laryngectomized patients have been using an EL as a means of communication for some time. However, the EL has a drawback in that it requires one hand to be used when speaking and can only produce a limited range of mechanical sounds (60 to 200 Hz). Furthermore, the appearance and main specifications of the device have hardly changed since it was first introduced. To solve these problems, we developed a new electric EL (hands-free EL) that reproduces realistic speech in a hands-free manner. This is the first report on the status of the development of this EL. In the development of our hands-free EL, we aimed to generate sounds close to those of natural voices for both men and women and to create a stylish hands-free design. With the hands-free EL, two different types of vibrators were used to produce a wide frequency range stably. In addition, the frequency of the vibrations was kept closer to that of a natural voice than with a conventional EL. Furthermore, the transducer was designed to be a wearable device that could be fixed to the holder, making it hands-free and thereby eliminating the problem of having a busy hand when speaking.
