50年泌尿男生殖系肿瘤发病和构成情况的变迁

的　探讨我国泌尿男生殖系肿瘤 5 0年发病情况的变迁。　方法　以北京大学泌尿外科研究所建所前后 5 0年间各时期泌尿男生殖系各器官肿瘤所占比例的变化为依据 ,对各种肿瘤发病情况进行评估。　结果　 195 1～ 2 0 0 0年间泌尿外科住院病人 2 85 2 1例 ,其中肿瘤 73 3 5例。前后2 5年泌尿男生殖系肿瘤住院病人分别占住院病人的 19.5 %和 2 8.2 %。 80年代后肾肿瘤、前列腺癌所占比例呈直线上升趋势 ,肾肿瘤从 10 .4 %上升至 2 8.7% ,前列腺癌从 3 .3 %上升至 13 .4 %。 (可能和诊断技术进步、人口老龄化和环境变化有关 ,前列腺癌和脂肪摄入量增加关系密切。)肾肿瘤及前列腺癌比例大幅上升。　结论　我国 2 0年的经济发展对泌尿男生殖系肿瘤的构成产生了巨大影响

Changing status of genitourinary cancer in recent 50 years

Objective As economy in China growing fast, it will in turn bring changes on the status of genitourinary cancer inpatients. Methods A survey has been made of urological inpatients from January 1951 to December 2000 in the Institute of Urology of Peking University to find the changing status of genitourinary cancer in the recent 50 years. Results From January 1951 to December 2000, there were 28 521 urological inpatients. The cancer patient in the first and second 25 years constituted 19.5% and 28.2% respectively. Since 1970s renal cancer and prostate cancer increased dramatically from 10.4% to 28.7% and 3.3% to 13.4% respectively. Conclusions The introduction of new diagnostic techniques, the expansion of the aged population and a high fat diet are considered to be responsible for this change.
