Prostatic cancer: some epidemiological features.

A S Donn, C S Muir

    Bulletin Du Cancer
    |January 1, 1985
    PubMed
    Summary

    Prostate cancer is common in older men, with varying rates globally. Latent prostate cancer is more common than clinical cases and its progression factors require further research.

    Area of Science:

    • Oncology
    • Epidemiology
    • Urology

    Background:

    • Prostate cancer is a frequent malignancy in aging males, with significant geographic and ethnic variations in incidence.
    • Latent (microscopic) prostate cancer is far more prevalent than clinically diagnosed disease and shows similar prevalence across diverse populations.
    • Current understanding of the relationships between tumor development, latency, and progression remains limited.

    Purpose of the Study:

    • To review the epidemiology of prostate cancer, highlighting disparities in incidence and mortality.
    • To discuss the concept of latent prostate cancer as a distinct entity for future research.
    • To explore potential etiological factors and propose avenues for future research into prostate cancer progression.

    Main Methods:

    • Review of existing epidemiological data on prostate cancer incidence and mortality.
    • Analysis of prevalence data for latent versus clinical prostate cancer.
    • Discussion of implicated etiological factors including hormonal, dietary, and genetic influences.

    Main Results:

    • Prostate cancer incidence and mortality are increasing globally, particularly in previously low-risk populations.
    • Latent prostate cancer prevalence is consistent across countries, unlike overt disease.
    • High-fat diets are a potential risk factor, possibly through hormonal mechanisms, but evidence requires further investigation.

    Conclusions:

    • Further research is needed to understand the progression from latent to invasive prostate cancer.
    • Studies focusing on populations like US Black and White men could elucidate risk factors.
    • Prevention strategies are not feasible with current knowledge; aetiopathogenesis requires deeper inquiry.
