Radioguided occult breast lesion localization using radiopharmaceuticals is a safe and effective method for precisely locating non-palpable breast abnormalities. This technique ensures accurate surgical removal of suspicious lesions, aiding in timely diagnosis and treatment.

Area of Science:

  • Nuclear medicine
  • Radiopharmacology
  • Breast imaging

Background:

  • Accurate localization of occult breast lesions is crucial for effective diagnosis and treatment.
  • Non-palpable lesions detected mammographically pose challenges for surgical excision.

Purpose of the Study:

  • To evaluate the efficacy of radiopharmaceutical methods for precise localization of occult breast lesions.
  • To assess the safety and patient tolerance of radioguided localization techniques.

Main Methods:

  • Sixty-one patients with mammographically detected non-palpable breast lesions underwent localization using technetium-99m-labeled human serum albumin macroaggregates (99mTc-MAA).
  • Radiotracer injection was guided by stereotactic mammography or ultrasonography, with scintigraphic verification.

  • Intraoperative localization utilized a gammaprobe, and specimen radiography confirmed microcalcification removal.

    • Main Results:

    • Successful radiotracer placement was achieved in 95.2% (60/63) of cases.
    • Sixty-one lesions were completely excised, with pathological examination revealing 47.6% breast cancers and 52.4% benign findings.
    • The method demonstrated high accuracy in guiding surgical removal of occult breast lesions.

    Conclusions:

    • Radioguided occult breast lesion localization using radiopharmaceuticals is a simple, safe, and well-tolerated procedure.
    • This technique facilitates accurate and complete excision of non-palpable breast abnormalities.
    • It represents a valuable tool in the management of breast cancer diagnosis and treatment.
