  Purpose

RATIONALE: Biopsy is the removal of cells or tissue for examination under a microscope. It is not yet known which type of breast biopsy is more effective for diagnosing breast lesions.

PURPOSE: Randomized diagnostic trial to compare the effectiveness of two different types of biopsy in patients who have breast lesions that cannot be felt upon examination.

Primary Outcome Measures:
  • Tissue Loss Rates for Each Arm [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Compare the effect of low dose radioactive seed localized breast biopsy versus needle localized breast biopsy on tissue loss in patients with nonpalpable breast lesions.

  • Operative Time Rates in Each Group [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Compare the effect of low dose radioactive seed localized breast biopsy versus needle localized breast biopsy on operative time in patients with nonpalpable breast lesions.


Secondary Outcome Measures:
  • Number of Participants with Adverse Events for Each Group [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]
    Review of adverse events utilizing Common Toxicity Criteria (CTC) V3.

Arms Assigned Interventions
Active Comparator: I: Radioactive Seed Localized Breast Biopsy
Arm I: Patients undergo radiographic placement of a radioactive seed (either iodine I 125 or palladium Pd 103) into the suspicious lesion. Patients then undergo surgery to remove the lesion along with the seed and a small margin of surrounding breast tissue followed 3 months later by a postoperative mammogram.
Procedure: Low dose radioactive seed followed by surgery and mammogram
either iodine I 125 or palladium Pd 103
Active Comparator: Arm II: Needle Localized Breast Biopsy
Arm II: Patients undergo a needle localized breast biopsy with a specimen x-ray.
Procedure: Needle localized breast biopsy with specimen x-ray

Detailed Description:

OBJECTIVES: I. Compare the effect of low dose radioactive seed localized breast biopsy versus needle localized breast biopsy on operative time and tissue loss in patients with nonpalpable breast lesions. II. Compare the cost effectiveness of these diagnostic methods in these patients. III. Demonstrate that radioactive seed localization allows for elimination of specimen x-ray in these patients. IV. Demonstrate that radioactive seeds may be placed safely for 1-7 days prior to surgical removal in these patients.

OUTLINE: This is a randomized study. Patients are randomized to one of two diagnostic arms. Arm I: Patients undergo radiographic placement of a radioactive seed (either iodine I 125 or palladium Pd 103) into the suspicious lesion. Patients then undergo surgery to remove the lesion along with the seed and a small margin of surrounding breast tissue followed 3 months later by a postoperative mammogram. Arm II: Patients undergo a needle localized breast biopsy with a specimen x-ray.
