Malignancy
NO
Combining individual data on screening for prostate cancer and cancer registry including prognostic survey in Gunma Prefecture, and subsequently investigating relationship between screening history and risk of death due to prostate cancer.
Efficacy
Case control study in Isesaki city (old Isesaki city; original community before municipal merger) and in Gunma prefecture excluding Isesaki city.
Investigating relationship between PSA-based screening history and death due to prostate cancer (estimating odds ratio) in men aged below 85 years old (the age of having life expectancy of 7 years or longer) Candidates for influencing factor on screening histories are followings;
1) Population-based PSA screening history before cancer detection: none vs. present
2) Diagnostic opportunity (data from MN report): screening vs. outpatient clinic due to having any urinary symptoms
3) Population-based PSA screening history within 2 years before cancer detection: none vs. present
4) Population-based PSA screening history within 5 years before cancer detection: none vs. present
5) Population-based PSA screening history within 5 years before cancer detection: none or only once vs. present more than once
<1> Case control study in Isesaki city (old Isesaki city; original community before municipal merger) and in Gunma prefecture excluding Isesaki city.
Investigating relationship between PSA-based screening history and death due to prostate cancer in men dead at the age below 85 years old in Isesaki city (old Isesaki city) and in Gunma prefecture excluding Isesaki city. Candidates for influencing factor on screening histories are followings;
Population-based PSA screening history within 10 years before cancer detection:
1) none vs. present
2) none or only once vs. present more than once
3) none, once, twice vs. present more than twice
Investigating above indicated primary and secondary outcomes in men dead due to prostate cancer at the age below 80 years old or 75 years old
<2> Retrospective cohort study: Estimating cumulative risk of detecting prostate cancer in the late clinical stage and death due to prostate cancer stratified by baseline PSA (0.0-1.0/1.1-2.0/2.1-3.0/3.1-4.0/4.1-10.0/10.1-20.0/20.1-50.0/50.1 or higher) and the age (50-54/55-59/60-64/65-69/70-74/75-79 years old)
<3> Etiological study
1) Time series study: Estimating relationship of annual percent change (APC) in age standardized incidence of prostate cancer (1992-2015), age standardized incidence of metastatic prostate cancer (1992-2015) and age standardized mortality of prostate cancer (1992-2020) with exposure rate of PSA screening until 2019, stratified by municipality and the year of initiation of population-based screening
2) Regional correlation study: Grouping municipalities according to exposure rate of PSA screening between the year of initiation of PSA screening and 2019, and subsequently investigating relationship between exposure rate of PSA screening and APC in age standardized incidence of prostate cancer (1992-2015), age standardized incidence of metastatic prostate cancer (1992-2015) and age standardized mortality of prostate cancer (1992-2020)
Observational
20 | years-old | <= |
Not applicable |
Male
1) Men aged above 20 years old and participating population-based screening for prostate cancer in Gunma Prefecture* between April 1992 and March 2020. *municipalities where Gunma Health Foundation have gotten entrusted population-based screening
2) Men aged above 20 years old and participating population-based screening for prostate cancer in old Isesaki city between April 2002 and March 2020.
3) Men diagnosed with prostate cancer and registered in Gunma Prefecture Cancer Registry between January 1992 and December 2015 from the municipalities where Gunma Health Foundation or Isesaki prostate cancer screening committee have conducted population-based screening
1) All inhabitants living in the municipalities decided not to participate in the present study (clarified the intention of opt-out for the present study)
2) All individuals who clarified the intention of opt-out for the present study (excluding data for the case-control study and the retrospective cohort study)
3) All individuals who died or could not clarify their own intention and whom direct relatives clarified the intention of opt-out for the present study (excluding data for the case-control study and the retrospective cohort study)
4) Men whom physicians or researchers recommended to exclude from the present study.

The analysis will be done by using the coupled databases of screening, cancer registration and information of prognosis, which were numbered without reference to individual informations, in both "Gunma University Center Mathematics and Data Science" and "Department of Urology, Gunma University Graduate School of Medicine".
Registrations in the databases are followings:
1) Individual number
2) Screening : hometown, age at the screening, PSA, history of complete examination, history of prostate biopsy, result of screening
3) Cancer registration : entries recorded in MN report
4) Information of prognosis : survival confirmation date, date of death due to prostate cancer, date of death due to other causes
