放疗能保存发音机能而治愈喉癌。现在不仅Ⅰ～Ⅱ期,而且Ⅲ～Ⅳ期喉癌也有用放疗治愈的。对T_1,T_2N_0M_9的声门癌首选放疗,出现复发时再行手术。因颈淋巴转移的危险性低,只照射喉部即可。用线型加速器照射T_1时,照射野为5×5cm,用~(60)CO照射野为6×6cm。照射T_2时照射野应再向周围扩大1cm。总量为60～66Gy,每次照射量为1.8～2.0Gy。90％的T_1可只用放疗治愈。余下的复发者中,90～95％可再行喉半/全切术进行补救。声带可动的T_2中,80～85％可只用放疗治愈,且保存发音机能。若有复发,可再行手术(同T_1)。
Radiotherapy can save voice function and cure laryngeal cancer. Not only stage I-II, but stage III-IV laryngeal cancer is curable with radiotherapy. For T_1, T_2N_0M_9 glottic cancer, radiotherapy is the first choice, and reoperation occurs when recurrence occurs. Due to the low risk of cervical lymph node metastasis, only the throat can be irradiated. When a linear accelerator is used to irradiate T_1, the radiation field is 5×5 cm, and the radiation field is 6×6 cm with a (60)CO. When irradiated with T_2, the irradiation field should be further expanded by 1 cm around. The total amount is 60 to 66 Gy, and the amount of irradiation is 1.8 to 2.0 Gy. 90% of T_1 can only be cured with radiotherapy. Among the remaining relapsers, 90-95% can be treated with laryngeal hemisection/total resection. In the movable vocal cords T_2, 80 to 85% can be cured only by radiotherapy, and the pronunciation function is preserved. If there is recurrence, surgery can be performed again (with T_1).
