Drill needle biopsy for breast cancer
The Japanese Journal of Surgery
|May 1, 1985
Summary
Electric drill needle biopsy accurately diagnosed early breast carcinoma in 90.4% of initial biopsies. This minimally invasive technique is effective for detecting small breast tumors, including those 10 mm or less.
Area of Science:
- Oncology
- Radiology
- Surgical Pathology
Background:
- Accurate and timely diagnosis of breast masses is crucial for effective treatment.
- Minimally invasive biopsy techniques are preferred for patient comfort and reduced complications.
Purpose of the Study:
- To evaluate the diagnostic accuracy and efficacy of electric drill needle biopsy for suspicious breast masses.
- To assess the suitability of this method for detecting early-stage breast carcinoma.
Main Methods:
- A retrospective analysis of 437 patients undergoing electric drill needle biopsy for breast masses between 1977 and 1983.
- Detailed review of biopsy results, including initial and subsequent procedures, and correlation with final diagnoses.
Main Results:
- The initial biopsy correctly diagnosed primary breast carcinoma in 90.4% of 104 patients.
- Of the 104 carcinomas, 59.6% were less than 2 cm, and 16.3% were 10 mm or less.
- The method demonstrated high accuracy for nodules < 2 cm, including those ≤ 10 mm.
Conclusions:
- Electric drill needle biopsy is an accurate and easily performed method for diagnosing suspicious breast masses.
- This technique is particularly suitable for detecting early breast carcinoma in outpatient or screening settings.
