The breast mass is one of the most common complaints in the breast disease. The diagnostic methods of the breast mass are history, physical examination, mammography, ultrasonography, CT, and MRI. In order to determine whether it is malignant or
benign
histologic diagnosis is necessary. The exact nonoperative tissue biopsy, which can reduce unnecessary operation in benign disease and be helpful in the planing of the treatment in malignancy, is indispensable to the patients of the breast
disease.
In
the nonoperative tissue biopsy, FNA(23-21G), Tru-cut needle biopsy(14G), needle core biopsy with a spring-loaded devices like the Biopty-cut needle biopsy(18G, 14G) were used commonly. The Biopty cut biopsy has an advantage of an easy handle for
one
hand, while the other hand can settle the movable breast mass. That is the very reason why we can use it on a hard and small mass, and it is very helpful to reduce complications such as hematoma. We reviewed our experience to compare the efficacy
of the
FNA, Tru-cut, and Biopty-cut with 140 cases from Jan. 1993 to Jun. 1995 at Kwangju Christian Hospital. Among 140 breast tissue biopsy, FNA were 127cases, Tru-cut were 71cases, Biopty-cut were 49cases In 127cases of FNA, 74(58.3%0 were benign,
36(28.3%)
were suspicious of malignancy, false negative were 17cases(13.4%), 4 of 17 were unsatisfactory specimen, sensitivity was 67.9%, accuracy was 86.6%. In 71cases of Tru-cut, 33(46.5%) were benign, 35(49.3%) were malignancy, false negative were
3(4.2%)
: 1
of 3 case was unsatisfactory specimen, sensitivity was 92.1%, accuracy was 95.8%). In 49 cases of Biopty-cut, 29 cases were benign, 19 were malignancy. False negative was 1 case(2.0%). sensitivity was 95.0%. accuracy was 98.0%. According to the
above
study, it was free from major complication such as excessive bleeding or infection, but some slight pain and congestion were noted in Tru-cut and Biopty-cut biopsy.
In conclusion, the proper use of Biopty-cut biopsy can be regarded as a good method of nonoperative tissue diagnosis which can be avoided by unnecessary operative diagnosis; with a higher diagnostic accuracy, sampling success rate, a better
quality
of
specimen, little complication, easy of performance. The histologic type and cancer prognostic factor could be obtained that couldn't be known in FNA.
