Accuracy of Digital Mammogram with High Frequency Ultrasonography in Diagnostic Cases BIRADS Categories 4 and 5 in Ratchaburi Hospital
Keywords:
BIRADS, breast cancer, mammogram, ultrasoundAbstract
Objective: The aims were to determine the accuracy of mammographic report according to the BIRADS categories 4 and 5 in Ratchaburi Hospital and evaluate cancer detection rate per 1,000 patients.
Methods: In this descriptive retrospective study, diagnostic mammograms with ultrasonograms performed in 13,981 women during January 2015 - December 2019 were analyzed. Statistics using program SPSS version 21, percentage of positive predictive value (biopsy performed, PPV3) and cancer detection rate were calculated.
Results: There were 1,008 patients with diagnosis BIRADS categories 4 and 5. Of all 475 patients were histologically confirmed cases of breast cancer. The PPV of the present study BI-RADS 4 was 27.3 %, BIRADS 5 was 90.2% and PPV3 in BIRADS 4 and 5 was 59.1%. The most common histological diagnosis of malignancy was invasive ductal carcinoma. Cancer detection rate (CDR) in diagnostic cases was 33.97 per 1,000 patients.
Conclusion: The BI-RADS reporting in Ratchaburi Hospital has the same accuracy as other institutions and is successful in predicting the chance of malignancy. However, preoperative tissue biopsy for histopathologic diagnosis is necessary before definitive treatment.
