下咽癌放疗后的生存率是多少 任淑惠 山西省肿瘤医院

下咽癌放疗后的生存率是多少 任淑惠 山西省肿瘤医院 下咽癌是发生于下咽部位的一种恶性肿瘤，下咽部位特殊相对不敏感的部位，因此下咽早期肿瘤不易被发现，初次就诊的患者大多以中晚期居多，因此总体治疗疗效较差。下咽癌的治疗效果与临床分期和治疗模式密切相关，早期的下咽癌，即1、2期下咽癌根治性放疗的五年生存率是50％－60％；晚期下咽癌3、4期的患者，无论是手术，还是单纯放疗总体疗效都不理想。单纯手术的5年生存率是30％－40％，而单纯放疗的5年生存率只有10％－20％。对晚期3、4期的患者，一般要用放疗加化疗或靶向治疗的综合治疗，相对疗效较好。中科院肿瘤医院做的一项小样品研究发现术前同期放化疗加手术或术前放疗加手术综合治疗患者5年生存率都有所提高，手术保喉几率也有提高，病人的生活质量也有提高。 What is the survival rate of hypopharyngeal cancer after radiotherapy Hypopharyngeal cancer is a kind of malignant tumor in the hypopharyngeal region, The hypopharyngeal region is particularly insensitive, Therefore, early hypopharyngeal tumors are not easy to be found, Most of the first visit patients were in the middle and late stage, Therefore, the overall treatment effect is poor. The therapeutic effect of hypopharyngeal cancer is closely related to clinical stage and treatment mode, Early hypopharyngeal cancer, The 5-year survival rate of radical radiotherapy for stage 1 and 2 hypopharyngeal cancer was 50% - 60%; Patients with advanced hypopharyngeal carcinoma stage 3 and 4, Whether it's surgery, The overall effect of radiotherapy alone is not ideal. The 5-year survival rate of simple operation was 30% - 40%, The 5-year survival rate of radiotherapy alone was only 10% - 20%. For patients with advanced stage 3 and 4, Generally, radiotherapy plus chemotherapy or targeted therapy should be used, The relative curative effect is better. A small sample study conducted by the Cancer Hospital of the Chinese Academy of Sciences found that the 5-year survival rate of patients who received preoperative radiotherapy and chemotherapy plus surgery or preoperative radiotherapy plus surgery combined therapy was improved, The chance of laryngeal preservation also increased, The quality of life of patients has also improved.
