    This study analyzed false-positive and false-negative neck nodes in head and neck squamous cell carcinoma (SCC). Results show T-stage is unrelated, but primary site and tumor differentiation impact node assessment accuracy.

    Area of Science:

    • Oncology
    • Head and Neck Surgery
    • Pathology

    Background:

    • Accurate assessment of neck node metastasis is critical for head and neck squamous cell carcinoma (SCC) management.
    • False-positive and false-negative findings in clinical neck node examination can lead to overtreatment or undertreatment.

    Purpose of the Study:

    • To determine the incidence of false-positive and false-negative neck nodes in patients with head and neck SCC.
    • To define the relationship between these false findings and primary tumor characteristics (site, T-stage, histologic grade).

    Main Methods:

    • Retrospective review of clinical and pathological records.
    • Analysis of 255 patients with head and neck SCC undergoing 266 radical neck dissections.

    Main Results:

    Related Experiment Videos

    • No significant relationship was found between primary tumor T-stage and the incidence of false-positive or false-negative neck nodes.
    • The benefit of elective neck dissection appears highest for oropharyngeal SCC and lowest for supraglottic SCC.
    • A lower incidence of false-negative neck nodes was observed in well-differentiated primary lesions.

    Conclusions:

    • Primary tumor T-stage does not predict false-positive or false-negative neck node findings in head and neck SCC.
    • Primary site and histologic grade are important factors influencing the accuracy of clinical neck node assessment.
    • These findings support tailored approaches to elective neck dissection based on primary tumor characteristics.
