在膀胱癌的危险因素中,吸烟的危险性最大。1961年以来,许多报告认为每日吸2盒烟以上者患癌的危险性是不吸烟者的7倍,但迄今尚未有关于吸烟与初发肿瘤的异型性、浸润深度及复发之间关系的报告。本报告是由一名医生就经他治疗过的100名膀胱癌患者,吸烟对异型性、浸润深度及复发的影响进行的概括。观察时间为6个月～25年(平均4.3年),年龄为15～92岁(平均64岁)。73例吸烟,27例不吸烟。
Among the risk factors of bladder cancer, smoking is the most dangerous. Since 1961, many reports suggest that patients who smoke more than 2 cigarettes a day risk 7 times more cancer than non-smokers, but so far no studies have been conducted on the relationship between smoking and the incidence of atypia, depth of invasion and relapse report. This is a summary of the effects of smoking on atypia, depth of invasion, and relapse in a group of 100 bladder cancer patients treated by a doctor. The observation time ranged from 6 months to 25 years (mean 4.3 years), and the age ranged from 15 to 92 years (mean, 64 years). 73 cases of smoking, 27 cases of non-smoking.
