下咽癌危及病人生命,恶性程度高,发展迅速,早期转移,生物学特性恶劣。早期无症状,部位隐蔽,难以发现,就诊时多为晚期,不论采取何种方法治疗效果都不满意,3、5年生存率低,预后不良。因此,下咽癌的治疗是一棘手难题。虽然下咽癌手术至今已有120年历史,由于术后缺少理想的咽食管修复方法,下咽癌的治疗一直沿用放疗。但放疗的效果不理想,5年生存率仅为10%左右。随着各种
Hypopharyngeal cancer endanger the lives of patients, high degree of malignancy, rapid development, early transfer, poor biological characteristics. Early asymptomatic, hidden parts, difficult to find, mostly late treatment, regardless of the method of treatment are not satisfied with the effect of 3, 5-year survival rate is low, the prognosis is poor. Therefore, the treatment of hypopharyngeal cancer is a tricky problem. Although hypopharyngeal cancer surgery has been 120 years of history, due to the lack of postoperative ideal pharyngoesophageal repair, the treatment of hypopharyngeal cancer has been followed radiotherapy. However, the effect of radiotherapy is not satisfactory, 5-year survival rate was only about 10%. With all kinds
