Fine-wire localization (FWL) biopsy is a valuable tool for diagnosing nonpalpable breast cancers, with a 40.6% positive finding rate. This diagnostic method aids in the early detection of breast cancer in women with abnormal mammographic findings.

Area of Science:

  • Radiology
  • Oncology
  • Surgical Pathology

Background:

  • Abnormal mammographic findings necessitate accurate diagnostic procedures.
  • Nonpalpable breast lesions require specialized techniques for biopsy.
  • Fine-wire localization (FWL) biopsy is an established method for targeting such lesions.

Purpose of the Study:

  • To evaluate the predictive value of fine-wire localization (FWL) biopsy.
  • To determine the diagnostic accuracy of FWL biopsy for nonpalpable breast abnormalities.

Main Methods:

  • A retrospective chart review was conducted.
  • Data from 239 FWL biopsies performed between 1991 and 1992 were analyzed.
  • Patient demographics and mammographic findings were correlated with biopsy results.

Main Results:

  • Malignant lesions were identified in 40.6% of the 239 biopsies.
  • Spiculated masses had the highest malignancy rate (90%).
  • Other mammographic findings like masses and microcalcifications also showed significant malignancy rates.

Conclusions:

  • The 40.6% positive finding rate confirms FWL biopsy's utility.
  • FWL biopsy is a valuable tool for diagnosing nonpalpable breast cancers.
  • This technique aids in the accurate diagnosis of suspicious mammographic findings.
