喉癌的放射治疗是怎样的 鲁萍 山西省肿瘤医院 放射治疗治疗喉癌疗效较好，尤其是早期声门癌。经过及时正确的放射治疗，其疗效基本与手术疗效相似，五年生存率在90%左右，且病人能保存发音功能，这对于工作和生活是非常重要的。由于声带癌多因音哑而发现较早，加之声带癌血运差，不易淋巴结转移，故声带癌治疗一般首先以放射治疗为主，万一复发亦还有手术机会。对于声门上区癌，因症状不明显而发现较晚，有的患者已出现颈部淋巴结转移，单纯性的手术治疗创伤大，功能损坏明显，全喉切除常不被患者所接受。如果采用综合性治疗是最佳选择，可先放疗使肿瘤明显缩小再行手术。这样可缩小手术范围，减少功能障碍也可获得较好疗效。如果有颈部转移者也可采用手术后放疗，其疗效亦较为满意。喉癌放疗的适应症范围较广：患者一般情况好，无明显呼吸困难者，最好为早期为主。中晚期患者以采用放疗加手术或术后加放疗，均会取得较好疗效。 What is radiotherapy for laryngeal cancer Radiotherapy is effective in the treatment of laryngeal cancer, Especially early glottic cancer. After timely and correct radiotherapy, Its curative effect is basically similar to that of surgery, The five-year survival rate is about 90%, And the patient can save the voice function, This is very important for work and life. Because vocal cord cancer is often found earlier because of hoarseness, In addition, the blood circulation of vocal cord cancer is poor, Lymph node metastasis is not easy, Therefore, the treatment of vocal cord cancer is mainly radiotherapy, In case of recurrence, there is also an opportunity for surgery. For supraglottic cancer, The symptoms are not obvious, so they are found later, Some patients have cervical lymph node metastasis, Simple operation is very traumatic, Obvious function damage, Total laryngectomy is often not accepted by patients. If comprehensive treatment is the best choice, The tumor can be reduced obviously by radiotherapy before operation. This reduces the scope of the operation, Reducing dysfunction can also achieve better results. If there is cervical metastasis, postoperative radiotherapy can also be used, The curative effect was also satisfactory. The indications of radiotherapy for laryngeal cancer are wide: patients are generally in good condition, No obvious dyspnea, It is better to focus on the early stage. In the middle and late stage, radiotherapy plus surgery or postoperative radiotherapy were used, All of them will get better effect.
