| Introduction: It is very important for internal quality control of medical centers to evaluate the diagnostic accuracy of frozen sections, because this diagnostic method forms the basis of patient treatment. This study aimed to determine the accuracy of frozen section in the diagnosis of breast lump.
Materials and Methods: In Be’sat and Imam Reza hospital lab more than 25 cases per year are received for frozen section. Totally, 59 consecutive frozen sections of breast lumps were examined from 2008-2013 and were considered for analysis. Frozen section diagnosis given in breast biopsies performed in 5 years was evaluated against the final pathology report of permanent sections.
Results: Age of patients ranged between 23 and 80 years (mean age 50.4 years). In 56 cases (98.24%), there was no difference between the frozen section diagnosis and final diagnosis. One case was false negative (1.69%). No false positive diagnosis was noted. In two cases (3.4%) frozen section diagnosis were deferred to permanent sections. The diagnostic accuracy of frozen section was 98.24%. The sensitivity, specificity, positive predictive value and negative predictive value were 97.61%, 100%, 100%, and 93.75%, respectively.
Conclusion: High accuracy of the frozen-section diagnosis in the breast lumps was confirmed in our study. |
