بررسی ارزش تشخیص نمونه برداری سوزنی ضایعات پستان با کمک روش های تصویربرداری

The evaluate the diagnostic value of image guided Fine Needle Aspiration (FNA) in breast lesions, the cytologic results of 401 patients were studied. All patients had either unpalpable masses or lesions who were hardly possible to localize by palpation and FNA was performed by single radiologist under ultrasound guide in all cases. The cytologic results were divided into four categories (inconclusive, benign, suspicious and malignant. Pathologic results were also divided into two categories (benign, malignant) and additional statistical analysis was conducted to find te cut-off point between benign and malignant cytologic results. Following cytologic results were obtained: 7.98 percent inconclusive, 67.83 percent benign, 10.97 percent suspicious, 13.22 percent malignant. Of the patients undergone breast operation after image guided FNA, the surgical pathology of 128 cases were found. In this study the sensitivity, specificity and accuracy of image guided FNA were calculated as 94.34 percent, 82.67 percent and 87.5 percent respectively. Person's coefficient analysis revealed significant correlations between FNA diagnosis and surgical pathology (P<0.001, r=0.66). Thus, image guided FNA of breast lesions can be a reliable substitute for the excisional biopsy breast operation in many patients.
