Abstract:
Objective To explore the differences between community-based population-wide early screening combined with two-way referral model and the traditional opportunistic screening model for early diagnosis of early-stage prostate cancer.Methods From August 2022 to April 2024,12815high-risk elderly males within the Fifth People's Hospital of Shanghai,Fudan University healthcare al-liance underwent population-wide prostate-specific antigen(PSA)screening across five community health centers.Among them,1005 cases with PSA＞4.0ng/ml were identified and referred via a two-way referral model to the Fifth People's Hospital of Shanghai,Fudan University for further evaluation.Prostate biopsies were performed on 445 eligible patients who consented(mean age was 65.6±6.8 years),and clinical data were collected as the community-based population-wide early screening combined with two-way referral mod-el group(Group A).During the same period,4600high-risk elderly males with lower urinary tract symptoms underwent opportunistic PSA screening at the Fifth People's Hospital of Shanghai,Fudan University identifying 700 cases with abnormal PSA levels.Biopsies were performed on 270 eligible patients who consented(mean age was 64.8±6.4 years),and clinical data were collected as the traditional op-portunistic screening model group(Group B).Baseline characteristics,positive rate of prostate cancer,clinical stages,and pathological grades were compared between the two groups.Results There were no statistically significant differences in age,PSA levels,family his-tory,body mass index(BMI),marital status and education level between the groups.There were 160 positive cases in Group A,the pos-itive rate was 35.9％,while there were 90 positive cases in Group B,the positive rate was 33.3％,with no significant statistical differ-ence(P=0.652).In Group A,100 cases(62.5％of diagnosed cases)were classified as clinical stage ≤T2N0M0,compared to 35 ca-ses(38.9％)in Group B,showing a significant statistical difference(P=0.023).Group A had 105 cases(65.6％of diagnosed cases)with International Society of Urological Pathology(ISUP)grade ≤3,while Group B had 30 cases(33.3％),showing a significant statis-tical difference(P=0.002).Conclusion Community-based population-wide early screening combined with two-way referral model showed no difference in the positive rate of prostate cancer compared to traditional opportunistic screening but exhibited advantages in diag-nosing early-stage prostate cancer.Wider adoption of this model may improve the current status of delayed staging and poor prognosis a-mong prostate cancer patients in China.
