CT in advanced gastric carcinoma: is exploratory laparotomy avoidable?

J Triller, R Roder, A Stafford

    European Journal of Radiology
    |August 1, 1986
    PubMed
    Summary

    Computed tomography (CT) accurately stages advanced gastric carcinoma, but exploratory laparotomy remains crucial for assessing operability. CT can help avoid surgery in specific cases with clear evidence of metastasis.

    Area of Science:

    • Oncology
    • Radiology
    • Gastroenterology

    Background:

    • Advanced gastric carcinoma presents challenges in staging and resectability assessment.
    • Accurate pre-operative evaluation is critical for treatment planning and patient outcomes.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of computed tomography (CT) in staging advanced gastric carcinoma.
    • To assess the reliability of CT in determining tumor resectability.

    Main Methods:

    • Retrospective analysis of CT scans from 40 patients with advanced gastric carcinoma.
    • Comparison of CT findings with pathological staging (pTNM classification) and surgical outcomes.
    • Evaluation of CT's accuracy in T, N, and M categories, overall staging, and resectability estimation.

    Main Results:

    • CT demonstrated high accuracy in T (90%) and M (80%) categories, and overall staging (72.5%).
    • Accuracy for the N category was lower (52.5%).
    • CT correctly estimated resectability in 80% of cases.

    Conclusions:

    • CT is a valuable tool for staging and assessing resectability in advanced gastric carcinoma.
    • Exploratory laparotomy is generally essential for definitive operability assessment.
    • CT findings may allow avoidance of laparotomy in select cases with extensive tumor infiltration or distant metastases.
