Large-needle thyroid biopsy: still necessary.

T A Broughan, C B Esselstyn

    Summary
    This summary is machine-generated.

    Fine-needle aspiration alone may miss thyroid cancers. Combining fine-needle aspiration with large-needle biopsy improves detection rates for follicular neoplasms and thyroid carcinoma.

    Area of Science:

    • Endocrinology
    • Surgical Pathology
    • Oncology

    Background:

    • Fine-needle aspiration (FNA) and large-needle biopsy (LNB) are diagnostic tools for nodular thyroid disease.
    • FNA allows 87% of patients to avoid surgery.
    • Concerns exist regarding FNA's ability to detect follicular neoplasms.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of FNA compared to LNB in identifying follicular neoplasms.
    • To determine if FNA alone is sufficient for diagnosing thyroid cancer.

    Main Methods:

    • Retrospective review of 46 patients undergoing FNA, LNB, and thyroidectomy.
    • Analysis of preoperative biopsy results and postoperative pathology findings.
    • Comparison of malignancy detection rates between FNA and LNB.

    Main Results:

    • Seventeen patients were diagnosed with thyroid carcinoma.
    • All 17 carcinoma cases had hypercellular LNB results.
    • Only nine of these 17 patients had FNA results suspicious of malignancy (p = 0.0078).

    Conclusions:

    • FNA alone is insufficient for detecting a significant number of thyroid cancers.
    • Concomitant use of LNB with FNA is crucial for accurate diagnosis of thyroid neoplasms.
    • LNB improves the detection of thyroid carcinoma missed by FNA.
