Abstract

Purpose
Cancer is a disease with high social costs, and policymaking through accurate statistics is very important. This study presents the national cancer statistics on the incidence of urological cancers in the Republic of Korea over 22 years, from 1999 to 2020.
Materials and Methods
Through the Korean Statistical Information Service, data on the incidence of urological cancers by sex and age in each year was obtained. For each urological cancer, the number of cases, crude incidence rate (CIR), and age-standardized incidence rate (ASR) were calculated, and the statistical trends were confirmed by joinpoint regression analysis.
Results
Urological cancers, which have increased ASR over 22 years, are as follows: prostate cancer (average annual percent change [AAPC]=6.72%, p-trend<0.05), testicular cancer (AAPC=5.26%, p-trend<0.05), ureter cancer (AAPC=4.16%, p-trend<0.05), kidney cancer (AAPC=4.14%, p-trend<0.05), renal pelvis cancer (AAPC=3.86%, p-trend<0.05), and total urological cancer (AAPC=4.37%, p-trend<0.05). Urological cancers, which has decreased ASR over 22 years, are as follows: penile cancer (AAPC= -2.93%, p-trend<0.05) and bladder cancer (AAPC=-0.31%, p-trend<0.05).
Conclusions
It was confirmed that the ASR of all urological cancers increased for 22 years, except for bladder and penile cancer. With the aging of the population, the CIR increased for all urological cancers. This study will serve as basic data for future research and policy decisions.
