    Summary

    Computed tomography (CT) accurately stages 82% of renal cell carcinoma cases, outperforming angiography. CT excels at identifying tumor spread to surrounding spaces and lymph nodes, aiding in cancer staging.

    Area of Science:

    • Radiology
    • Oncology
    • Urology

    Background:

    • Renal cell carcinoma (RCC) staging is crucial for treatment planning.
    • Accurate staging requires detailed assessment of tumor extent and metastasis.
    • Limitations exist in current staging methods for detecting subtle tumor invasion.

    Purpose of the Study:

    • To compare the accuracy of computed tomography (CT) staging against histopathologic staging in renal cell carcinoma (RCC).
    • To evaluate CT's effectiveness in detecting tumor infiltration and lymph node involvement in RCC patients.

    Main Methods:

    • Retrospective analysis of 68 patients with renal cell carcinoma.
    • Comparison of computed tomography (CT) staging with histopathologic findings.
    • Utilized Robson's staging classification scheme for evaluation.

    Main Results:

    • Computed tomography (CT) correctly classified tumor stages in 82% of cases.
    • CT demonstrated superiority over angiography in detecting peri- and pararenal space infiltration.
    • CT effectively identified lymph node metastases, outperforming angiography.

    Conclusions:

    • Computed tomography (CT) is a valuable tool for staging renal cell carcinoma (RCC).
    • CT offers improved detection of tumor invasion and metastasis compared to angiography.
    • Further refinement may be needed for CT to accurately assess tumor extension into the renal vein near the hilus.
