摘要

乳癌是台灣婦女死於癌症的主要原因之一。本篇即舉出平均年齡為37歲的46例，以評估X光針刺定位檢查，用於偵測臨床上為隱匿性乳房病灶的效應。乳房攝影的發現，包括微小鈣化點併／或腫塊顯影。被定位的病灶中，其病例數以微絲鈣化點佔最多(76.1%)，以微小鈣化點合併腫塊顯影佔最少(78.4%)，惡性病灶以腺管內癌佔最多(88.9%)，而有一例則為腺管原位癌(11.1%)。總括而言，癌症占16.7%，與國外報告一致。我們的結論是X光針刺定位檢查，對於定位摸不到的乳房隱匿性病灶，是一項有效的檢查。

Breast cancer is still one of the major causes of cancer deaths for women in Taiwan. To assess the validity of mammographic needle localization in detecting clinically occult breast tumors, we performed needle localization procedures on 46 cases, and the mean age of the patients was 37 years. The mammographic findings included microcalcifications and/or mass density. The localized lesion was most frequently microcalcification (76.1%) and least frequently mass density with microcalcifications (10.9%). The most common pathological findings for benign lesions was fibrocystic change (78.4%) and intraductal carcinoma (88.9%) for malignant tumors. There was also one case of ductal carcinoma in situ (11.1%). Overall, the incidence of positive biopsies for cancer was 19.6%, which was similar to that in other countries. We conclude that the needle localization is a valid procedure for localizing non-palpable occult breast lesions.
