The incidence of cancer is sharply increasing. Cancer is a leading cause of death as well as a significant burden on society. The incidence of urological cancer has shown a higher than average increase and will become an important concern in the future. Therefore, an overall and accurate understanding of the incidence of urological cancer is essential. In this study, which was based on the Korea National Cancer Incidence Database, annual incident cases, age-standardized incidence rates, annual percentage change (APC), and distribution by age group were examined in kidney, bladder, and prostate cancers, respectively. From 1999 to 2011, the total number of each type of urological cancer was as follows: kidney cancer (32,600 cases, 25.5%), bladder cancer (37,950 cases, 29.7%), and prostate cancer (57,332 cases, 44.8%). The age-standardized incidence rates of prostate cancer showed a significant increase with an APC of 12.3% in males. Kidney cancer gradually increased with an APC of 6.0% for both sexes and became the second most frequent urological cancer after 2008. Bladder cancer showed no significant change with an APC of -0.2% for both sexes and has decreased slightly since 2007. The distribution of kidney cancer according to age showed two peaks in the 50- to 54-year-old and 65- to 69-year-old age groups. Bladder and prostate cancers occurred mostly in the 70- to 74-year-old age group. The proportions of male to female were 2.5:1 in kidney cancer and 5.6:1 in bladder cancer. We have summarized the incidence trends of kidney, bladder, and prostate cancers and have provided useful information for screening and management of these cancers in the future.

OBJECTIVETo assess the changes in constituents of genitourinary cancer inpatients in Beijing following the growing economy of China.

METHODSUrological inpatients treated from January 1951 to December 2000 at the Institute of Urology, Peking University were studied retrospectively.

RESULTSIn 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.

CONCLUSIONThe 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.

A nation-wide study was performed to estimate the incidence of bladder, kidney, renal pelvis and ureter, prostate, testicular and other genitourinary cancer among Koreans in Korea using medical records of the inpatients of the beneficiaries of the Korea Medical Insurance Corporation (KMIC) from Jan. 1, 1989 to Dec. 31, 1989. The crude incidence rate of bladder cancer (ICD-9 188) is estimated to be 4.43 and 0.98 per 100,000 in males and females, respectively. Around 1,093 new cases of bladder cancer (895 male and 198 female) are estimated to occur in a year. The adjusted rate for the world population is 7.76 in males and 1.19 in females which is similar to that of Japanese in Osaka and Chinese in Shanghai, but lower than in American whites and blacks. The crude incidence of kidney, renal pelvis and ureteral cancer (ICD-9 189) is estimated to be 1.61 and 0.87 in males and females, respectively. Around 507 new cases of kidney, renal pelvis and ureteral cancer (332 male and 175 female) are estimated to occur in a year. The adjusted rate for the world population is 2.69 in males and 1.04 in females. In the prostate (ICD-9 185), the crude incidence rate of cancer is estimated to be 1.36. Around 274 new cases of prostate cancer are occurring in a year. The adjusted rate for the world population is 2.98 which is similar to the Chinese rate. The incidence of genitourinary cancer continuously increases with age.
