Colon and rectal carcinoma: spatial distribution and detection.

D D Maglinte, K J Keller, R E Miller

    Summary

    Digital rectal exams and sigmoidoscopy miss many colon cancers. A 20-year study shows increasing cecal cancers, highlighting the need for full colon evaluation. Barium pneumocolon is recommended for high-risk patients.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Diagnostic Imaging

    Background:

    • Traditional screening methods like digital rectal examination and sigmoidoscopy have limitations in detecting colon cancers.
    • Recent studies question the efficacy of these methods, suggesting a significant number of colorectal cancers are missed.

    Purpose of the Study:

    • To analyze the changing distribution of colorectal carcinoma sites over a 20-year period.
    • To evaluate the effectiveness of current screening methods in detecting cancers across the entire colon.

    Main Methods:

    • Analysis of 2,298 cases of colorectal carcinoma diagnosed over two decades.
    • Examination of cancer incidence and location, including rectum, sigmoid, cecum, ascending, and transverse colon.

    Main Results:

    • The rectum (34%) and sigmoid colon (25%) were the most common cancer sites.
    • A notable increase in cecal cancer incidence and a decrease in rectal cancer incidence were observed over 20 years.
    • Cancers in the cecum, ascending, and transverse colon (34% of lesions) are beyond the reach of flexible sigmoidoscopy.

    Conclusions:

    • The changing distribution of colon cancer sites necessitates improved screening techniques.
    • Barium pneumocolon examination is suggested as a valuable tool for screening high-risk patients due to its ability to evaluate the entire colon.
