초록
유방종괴의 감별진단을 위해 탈륨스캔을 시행하여 다음과 같은 결과를 얻었다. 1) 유방암 11예 중 10예에서 양성소견을 보였다(sensitivity 90.9%). 2) 위음성 1예는 화학요법을 받았던 환자로 종괴의 크기는 직경 1cm이하였다. 3) 병리조직학적으로 양성인 17예와 추적관찰상 악성을 의심할 수 없었던 3예 등 20예 중 17예에서 탈륨섭취가 없었다(specificity 85% ) 4) 섬유낭성 질환(fibrocystic disease)13예 중 3예에서 위양성 소견을 보였으며 섬유선종(fibroadenoma)3예와 1예의 엽상낭육종(cystosarcoma phyllodes)에서는 섭취를 보이지 않았다. 5) 이상의 결과 악성과 양성 감별의 정확도는 87.1%로써 유방종괴의 감별진단에 탈륨 스캔이 한 방법이 되리라 생각된다.
The purpose of this study is to evaluate thallium scanning as a potential test in differentiating malignant from benign lesions of breast. Thirty-one female patients underwent thallium scan of the breast. After intravenous injection of 74-111 MBq(2-3 mCi)of thallium-201, anterior and lateral images were obtained. We compared thallium scans with pathological results. Of 11 patients with breat cancers, 10 cases(90.9%) were detected using thallium scan. Thallium scan obtained in one patient who had breast cancer but received several cycles of chemotherapy did not show thallium uptake. The smallest detectable cancer was 1.5cm in diameter. In contrast, there is no thallium accumulation in breasts of 17 of 20 patients with benign disease(85%). Three cases of 13 fibrocystic disease show thallium uptake in their breast. In conclusion, thallium scan is an effective test in differentiating benign from malignant lesion.
