    Area of Science:

    • Oncology
    • Public Health

    Background:

    • Colorectal carcinoma screening programs aim to detect cancer early.
    • Germany introduced free routine screening for colorectal carcinoma, including digital rectal examination (1971) and fecal occult blood testing (1977).

    Purpose of the Study:

    • To evaluate the impact of free routine colorectal cancer screening on diagnostic indicators.

    Main Methods:

    • Analysis of diagnostic data from a single hospital following the implementation of screening programs.
    • Comparison of colorectal carcinoma diagnoses before and after the introduction of screening.

    Main Results:

    • A 30% increase in the diagnosis of Dukes' stage A (early-stage) colorectal carcinomas.
    • Reduction in the average time from symptom onset to diagnosis, from 5 months to 3.8 months.

  • A 10% decrease in the proportion of inoperable colorectal carcinomas.

    • Conclusions:

    • Routine colorectal cancer screening significantly improves early detection rates.
    • Screening implementation has shortened diagnostic intervals and reduced the incidence of advanced-stage disease.
