ZNAČAJ DIGITALNE STEREOTAKSIJSKE BIOPSIJE U KORELACIJI SA PATOHISTOLOŠKIM POSTOPERATIVNIM NALAZIMA

Aim : This research was conducted with the aim of analyzing the accuracy and diagnostic value of digital stereotactic breast biopsy compared to the postoperative histopathological findings. Methods : A retrospective-prospective study was carried out over a period of 10 months, involving 30 female patients who underwent stereotactic breast biopsy. Data were collected on BI-RADS status, histopathological findings after stereotactic breast biopsy and after surgical excision, basic demographic and relevant medical history data. The patients were divided according to the degree of malignancy into three groups: patients with benign, patients with suspicious and patients with malignant pathohistological findings. The BIS and RIS systems were used for data collection, and the data were statistically analyzed using STATISTICA for Windows. Results : All patients had a radiological finding of BI-RADS 3 or higher. Histopathological results after stereotactic biopsy showed benign findings in 17 patients (B1 and B2), borderline malignant changes were present in 4 patients (B3), one patient had a lesion suspicious for malignancy (B4), and 8 had confirmed malignant lesions (B5). Out of the total 30 patients, 13 underwent surgical treatment. Postoperative histopathological findings in 4 patients showed benign changes, 6 patients had an invasive form of carcinoma, including 5 with invasive NST breast carcinoma and one characterized as invasive ductal breast carcinoma, while three patients had Ductal Carcinoma In Situ (DCIS). A correlation test was performed between the estimated degree of malignancy from the pathohistological findings after stereotaxic biopsy and after surgical operation. Spearman's ρ test showed a significant correlation between the two methods (p < 0.001). Conclusion : The results of histopathological analysis of samples obtained through the stereotactic biopsy method largely correlate with the postoperative histopathological diagnosis in patients who underwent surgical treatment.
