乳头溢液肿瘤标志物检测在乳腺癌早期诊断中的应用

目的探讨乳头溢液肿瘤标志物癌抗原相关蛋白153（CA153）和癌胚抗原（CEA）检测在乳腺癌早期诊断中的价值。方法对153例乳头溢液患者按疾病类型分为良性病变组91例（均为乳腺良性病变患者）和乳腺癌组62例（均为乳腺癌患者），同时选取同期正常分娩的产妇40例为对照组，应用电化学发光法检测各组乳头溢液和血清CA153、CEA水平。结果乳腺癌组乳头溢液CA153、CEA明显高于良性病变组和对照组（CA153：t=28．949、33．844；CEA：t=19．773、16．623，均P〈0．01），乳头溢液肿瘤标志物阳性检出率明显高于血清阳性检出率（均P〈0．05）。结论乳腺癌患者乳头溢液肿瘤标志物CA153、CEA阳性检出率高于血清阳性检出率，对早期诊断乳腺癌具有重要价值。

Application of tumor markers in nipple discharge in early diagnosis of breast carcinoma

Objective To study the clinical value of nipple discharge detection in the early diagnosis of breast cancer,CA153 ,CEA levels were measured both in nipple discharge and serum. Methods 153 consecutive patients with nipple discharge in Rizhao hospital were studied,among them there were 91 cases with breast cancer and 62 cases with benign disease. The nipple discharged and serum from the 153 cases with nipple discharged were collected and CA153, CEA levels were measured with electrochemiluminescence method. Results The CA153, CEA levels of nipple discharge in breast cancer were significantly higher than the control group(CA153:t =28.949,33.844;CEA:t = 19.773,16.623, all P ＜ 0.01). The positive rate of CA153, CEA in nipple discharge were significantly higher than in the serum (P ＜ 0.05). Conclusion The positive rate of CA153, CEA in nipple discharge were significantly higher than in the serum. The detection of CA153 ,CEA had important value in the early diagnosis of breast cancer.
