乳腺癌的预后与其病期有关,但有些早期病例在短期内出现发展,为此作者利用CA15—3测定作前瞻性研究.爱尔兰Galway医院外科自1986年起对乳腺癌病人术前均作血浆CA15—3测定,术后1月,以后第1年每3个月、第2年每6个月和由此每年复查一次、在573例病人中,168例系Ⅰ期,其肿瘤<2 cm,腋淋巴结阴性.均作乳腺或肿块切除,清除腋淋巴结,并加用放疗,CA15—3用放免法测定,正常值上限为30u/mL. The prognosis of breast cancer is related to its stage of disease, but some early cases develop in the short term. Therefore, the authors used the CA15-3 assay as a prospective study. Galway Hospital of Ireland has performed plasma CA15 preoperatively for patients with breast cancer since 1986. - 3 determinations, 1 month after surgery, every 3 months after the first year, every 6 months during the 2nd year, and review once a year thereafter. In 573 patients, 168 cases were of stage I and their tumors were < 2 cm. Axillary lymph node negative. All for breast or lumpectomy, removal of axillary lymph nodes, plus radiotherapy, CA15-3 radioimmunoassay determination, the upper limit of normal value is 30u/mL.
