    Pelvic lymph node dissection in prostate cancer patients revealed that 24% of those thought to have no cancer spread actually had positive lymph nodes. This highlights the importance of accurate staging for effective prostate cancer treatment.

    Area of Science:

    • Urology
    • Oncology
    • Surgical Pathology

    Background:

    • Accurate staging is crucial for effective prostate cancer management.
    • Clinical assessment of lymph node status can be unreliable.
    • Pelvic lymph node dissection (PLND) provides definitive pathologic staging.

    Purpose of the Study:

    • To compare clinical staging with pathologic staging based on pelvic lymph node dissection in prostate cancer patients.
    • To determine the incidence of occult lymph node metastasis in clinically node-negative patients.

    Main Methods:

    • Retrospective analysis of 105 prostate cancer patients who underwent pelvic lymph node dissection.
    • Comparison of clinical assessment of nodal status with histopathologic findings.
    • Statistical analysis to determine the discrepancy between clinical and pathologic staging.

    Main Results:

    • Twenty-four percent (24%) of patients clinically presumed to be node-negative were found to have positive lymph node involvement upon pathologic examination.
    • This indicates a significant rate of understaging based on clinical evaluation alone.

    Conclusions:

    • Clinical staging underestimates lymph node involvement in a substantial proportion of prostate cancer patients.
    • Pathologic confirmation via pelvic lymph node dissection is essential for accurate staging and treatment planning in prostate cancer.
