비촉진 유방병변에 대한 세침국소화화 조직생검의 후향적 분석 = A Retrospective Analysis of Needle Localization and Biopsy of Non-palpable Lesions in the Breast

다국어 초록 (Multilingual Abstract)

The more frequent use of screening mammography, along with improved equipment and technique, is today resulting in an increasing detection rate for suspicious non palpable lesion and thus and an increasing need for needle localizations and biopsies.
From August 1992 to December 1994, 56 needle hookwire guided biopsies were performed at our institution for non palpable mammographically detected abnormalitites.
Patients ranged in age from 27 to 71 years(a mean of 45.8 years(
Of the total, 8(14.3%) were found to be malignant.
Fithy percent of maliganat lesions were carcinoma in situ and 50 percent were invasive carcinoma.
The chance of a biopsy containing a malignant lesion was 16.7 percent if the biopsy was done because of a microcacification on mammography, 6.3 percent for mass densities and 25 percent if both were present.
Benign pathological lesions were proved in 48 cases (85.7%). The most common benign lesion was fibrocystic disease.
Specimen roentgenography was done in all cases.
Minot complication of needle hookwire insertion occured in one patient who had a hematoma requiring evacation .
Two patients experienced faintness, dizziness and syncope during needle localization.
The morbidtity and mortality rates for biopsy of the breast were nil.
