Changing constituents of genitourinary cancer in recent 50 years in Beijing
1Institute of Urology, Peking University, Beijing 100034.
Objective:
To assess the changes in constituents of genitourinary cancer inpatients in Beijing following the growing economy of China.
Methods:
Urological inpatients treated from January 1951 to December 2000 at the Institute of Urology, Peking University were studied retrospectively.
Results:
In the period of about 50 years 28 474 urological inpatients were reviewed. Cancer patients in 1951-1965 and 1966-2000 comprised 19.5% and 28.2%, respectively [corrected]. Since the 1970s the incidence rates of renal cancer and prostate cancer increased dramatically from 10.4% to 28.7% and from 3.3% to 13.4%, respectively.
Conclusion:
The introduction of new diagnostic instruments, the expansion of the aged population and a high fat diet are considered to be responsible for the change of constituents of genitourinary cancer inpatients.
