摘要
用CA15I－3RIA测定了41例术前乳腺肿瘤和113例乳腺癌术后患者的血清。其中，术前25例为乳腺癌，其灵敏度为20．0％，特异性为93．7％；59例诊断为乳腺癌术后复发者，灵敏度为71．2％。50例诊断为骨转移者，灵敏度为78．0％．结果表明：由于CA15－3对早期乳腺癌的灵敏度较低，不适于作乳腺癌普查。但是，它对于乳腺癌术后复发、转移，尤其是对骨等脏器的转移具有较高的诊断价值。
Serum CA15-3 levels of 41 pre-operative patients with breast tumor and 113post-operative patients with breast cancer were meassured by radioimmunoassay.The sensitivity and specificity were 20%, 93.7%, and 71.2%, respectively. In 50patients with bone metastasis, the sensitivity was 78.0%. It appears that due to itslow sensitivity for early diagnosis, CA15-3 RIA has little use for screening in generalpopulation to detect primary breast cancer in early stage but is benefical fordetecting its metastasis and recurrence.
