目的:提高早期诊治原发性输尿管癌水平。方法:对1973～1996年经手术及病理证实的50例原发性输尿管癌进行回顾性分析。结果:46例获得随访,随访时间6个月～10年,总的5年生存率为54.3%,根治性与保守性手术术后5年生存率分别为55.2%和52.9%;根治性手术后的膀胱癌发生率(24.1%)低于保守性手术(41.2%)。结论:原发性输尿管癌的预后主要取决于肿瘤的分期、分级,进一步提高早期诊治水平是提高患者生存率的关键
Objective: To improve the early diagnosis and treatment of primary ureteral cancer. Methods: A retrospective analysis of 50 cases of primary ureteral carcinoma confirmed by operation and pathology from 1973 to 1996 was performed. Results: 46 patients were followed up for 6 months to 10 years, the overall 5-year survival rate was 54.3%. The 5-year survival rates after radical surgery and conservative surgery were 55.2% and 52.9% respectively. After radical surgery The incidence of bladder cancer (24.1%) was lower than that of conservative surgery (41.2%). Conclusion: The prognosis of primary ureteral carcinoma mainly depends on the staging and grading of the tumor, and further improving the early diagnosis and treatment is the key to improve the survival rate of patients
