因膀胱癌的总发病率很低,目前尚不能普遍实行膀胱癌的常规筛选,研究人员使用前列腺、肺、结肠直肠和卵巢癌试验(PLCO)和国家肺癌筛选试验(NLST)来识别高危患者,希望从中能够获得益处。方法:从PLCO和NLST选取相关资料以测定其膀胱癌风险,并按其性别、种族来源和吸烟(Nicotinkomsus)进行分类,使用2χ检验比较其发病率。结果:154 898例PLCO中发现膀胱癌1 430例,53 173例NLST中发现膀胱癌439例,其中Ⅲ/Ⅳ级膀胱癌分别占
Because of the low overall incidence of bladder cancer, routine screening for bladder cancer is not currently practiced. The researchers identified high-risk patients using the Prostate, Lung, Colorectal and Ovarian Cancer Trial (PLCO) and National Lung Screening Screening Test (NLST) Hope to benefit from it. METHODS: Relevant data were selected from PLCO and NLST to determine the risk of bladder cancer, categorized according to their sex, ethnic origin, and smoking (Nicotinkomsus), and their incidence was compared using a 2χ test. RESULTS: Of the 154 898 PLCO cases, 1 430 were found in bladder cancer and 439 were found in 53 173 cases of NLST. Among them, grade Ⅲ / Ⅳ bladder cancer accounted for
