KTP-LasersA recent study from Massachusetts General Hospital published in the December edition of the Annals of Otology, Rhinology, and & Laryngology confirmed that the KTP (green light) laser is effective in treating small to midsize cancers of the voicebox. The researchers looked at 117 patients and found 96% of patients were disease free and still living with their larynx 4.5 years after treatment. When looking specifically at small size tumors, they found 96% (79/82) had no recurrence at 3 years. Moderate size tumors also had good results showing 80% (28/35) were recurrence free. Laser therapy is an effective tool when treating voicebox cancers and should be considered as alternative to radiation for early glottic cancer.
