    Summary

    X-ray guided percutaneous fine-needle biopsies using the Nordenström cannula achieved a 74% positive rate for malignant lesions. Negative biopsies require further investigation to rule out false negatives in cancer diagnosis.

    Area of Science:

    • Radiology
    • Oncology
    • Pathology

    Background:

    • Percutaneous fine-needle biopsy is a key diagnostic tool.
    • Accurate interpretation of biopsy results is crucial for patient management.

    Purpose of the Study:

    • To evaluate the efficacy of X-ray guided percutaneous fine-needle biopsies using the Nordenström cannula.
    • To assess the diagnostic accuracy and clinical utility of this method over extended follow-up.

    Main Methods:

    • 100 patients underwent X-ray guided percutaneous fine-needle biopsies.
    • The Nordenström cannula was utilized for all procedures.
    • Clinical follow-up ranged from 14 to 30 months.

    Main Results:

    • A 74% positive rate for malignant lesions was achieved.
    • Histologically negative biopsies were further analyzed.
    • Extended follow-up provided crucial data for interpreting negative results.

    Conclusions:

    • X-ray guided fine-needle biopsy with the Nordenström cannula is effective in diagnosing malignant lesions.
    • Negative biopsy results should be treated with caution and confirmed with further investigations due to potential false negatives.
