CONTEXT:
Fine-needle aspiration biopsy of the breast has been used as a diagnostic step in the investigation of palpable breast lesions in the Department of Surgery at Jose R. Reyes Memorial Medical Center (JRRMMC) for more than a decade.
OBJECTIVE:
The purpose of this study is to evaluate the accuracy of fine needle aspiration with histologic correlation by the Department of Pathology.
STUDY DESIGN: Retrospective Study
STUDY SETTING: Department of Surgery, JRRMMC
MANEUVERS:
This was performed using results of FNAB from January to December 2004. All women who had had FNAB with histopathologic confirmation of the diagnosis were included. Fine-needle aspirations were interpreted as malignant or benign. Histopathologic diagnosis includes incisional, excisional, and mastectomy specimens.
RESULTS:
A total of 38 cases fulfilled the criteria. There were 28 (73.7%) malignant fine needle aspiration diagnoses, with 15 (39.5%) false negative cases. The test is 46.4% sensitive, 100% specific, 100% positive predictive value and 40% negative predictive value.
CONCLUSION:
Fine needle aspiration biopsy (FNAB) done at JRRMMC from January to December 2004 is a less sensitive and less accurate, but highly specific method of assessing palpable breast mass. In the hands of an experienced aspirator and with initial assessment done by the cytopathologist, lower rates of false negative diagnosis can be achieved.
