Second-look laparotomy based on CEA elevations in colorectal cancer

F F Attiyeh, M W Stearns

    Cancer
    |May 1, 1981
    PubMed
    Summary

    Second-look laparotomy aids in detecting recurrent colorectal cancer after initial surgery. Elevated Carcinoembryonic Antigen (CEA) levels are key indicators for this procedure, improving detection rates.

    Area of Science:

    • Oncology
    • Surgical Oncology
    • Gastroenterology

    Background:

    • Colorectal adenocarcinoma recurrence can be asymptomatic.
    • Carcinoembryonic Antigen (CEA) is a tumor marker used in colorectal cancer management.
    • Early detection of recurrence is crucial for patient outcomes.

    Purpose of the Study:

    • To evaluate the efficacy of second-look laparotomy in patients with elevated CEA levels after curative resection for colorectal adenocarcinoma.
    • To determine the correlation between CEA levels, time to surgery, and rate of elevation with the detection of recurrent disease and resectability.

    Main Methods:

    • Retrospective analysis of 32 patients undergoing second-look laparotomy due to significant CEA elevation post-resection.
    • CEA levels, time delay to surgery, and rate of CEA increase were recorded.
    • Surgical findings and patient outcomes were documented.

    Main Results:

    • Recurrent disease was found in 89% of patients (33/37 laparotomies).
    • Resectability rate was 43% (16/37), with lower CEA levels, shorter delays, and slower elevation rates correlating with better resectability.
    • Survival outcomes included 8 patients alive and well, 10 alive with disease, and 14 dead of disease.

    Conclusions:

    • Elevated CEA levels are a significant indicator for selecting patients for second-look laparotomy in colorectal adenocarcinoma.
    • The procedure can detect recurrent disease, and resectability is influenced by CEA kinetics.
    • Further follow-up is needed to confirm the impact on long-term survival.
