According to the results of a study conducted in Italy and published in the Archives of Otolaryngology – Head & Neck Surgery, selected patients with glottic cancer recurrence after radiation therapy can be safely and effectively treated with endoscopic carbon dioxide laser surgery.
The glottis is the middle part of the larynx where the vocal cords are located. Early-stage glottic cancer may be treated with radiation therapy or surgery.
Recurrent glottic cancer refers to glottic cancer that has returned following treatment. When glottic cancer recurs locally (in the area of the initial cancer) after radiation therapy, treatment of the recurrence often involves surgery.
Endoscopic laser surgery is a minimally invasive technique in which a scope is passed through the mouth and into the throat, and a laser is used to remove the cancer.
To assess endoscope laser treatment of glottic cancer recurrence, researchers in Italy conducted a study among 37 patients whose initial glottic cancer had been treated with radiation therapy. The study was restricted to patients with recurrences that were confined to the vocal cords or who had less than 5 mm of extension into the supraglottis or subglottis.
The researchers conclude that for selected patients with glottic cancer recurrence after radiation therapy, endoscopic laser surgery is safe and effective and allows for laryngeal preservation in a high proportion of cases. The researchers note, however, that women may have a high risk of laryngeal stenosis with the procedure.
