本文通过对242例咽上-中部恶性肿瘤的治疗观察,分析并研究了其远期疗效(5年存活率)的评价标准。患者中计咽上部恶性肿瘤116例,咽中部者126例,平均年龄51.6±2.8岁,男女比为1.78∶1。第Ⅱ、Ⅲ、Ⅳ期患者分别占9.9、52.9和37.2%。本部恶性肿瘤的疗效与肿瘤及患者机体的生物学特性及治疗方法恰当与否有关,前者包括性别、年龄、机体中毒程度、病程、肿瘤生长方式和速度、其浸润扩散及转移特点等;后者由其近及远期疗效判定。临床分析发现:女性患者预后比男性好,五年存活率分别为45.9±4.8%和29.8±4.0%,原因可能与女性本身的生物学特性及她们与易导致咽粘膜瘀血和慢性刺激的烟酒等接触机会较少有关。远期疗效较好者中大多属21～30岁和31～ This article analyzes and studies the long-term efficacy (5-year survival rate) evaluation criteria of 242 cases of suprahopal-middle malignant tumors. In the patient, 116 cases of upper pharyngeal malignancy and 126 cases of central pharynx were counted, and the average age was 51.6±2.8 years. The male to female ratio was 1.78:1. Patients with stage II, III, and IV accounted for 9.9, 52.9, and 37.2%, respectively. The efficacy of the Department of Malignant Tumor is related to the tumor and the patient’s biological characteristics and treatment methods. The former includes gender, age, degree of body poisoning, disease course, tumor growth pattern and speed, infiltration, diffusion and metastasis characteristics; Judging by its near and long-term efficacy. Clinical analysis found that female patients had a better prognosis than males, and the five-year survival rates were 45.9±4.8% and 29.8±4.0%, respectively, which may be due to the biological characteristics of females and their association with cigarettes that easily cause pharyngeal mucosal bleeding and chronic irritation. Wine and other contact opportunities are less relevant. Most of the long-term curative patients are 21 to 30 years old and 31 to
