A new tumour marker, mucin-like carcinoma-associated antigen (MCA), was evaluated in 176 breast cancer patients classified either as free of tumour (NED, n = 141) or as having metastases (PD, n = 35). During the 5 year follow-up, 842 measurements of MCA and 363 measurements of CA 15-3 were done. MCA levels were significantly increased in the PD group (P = 0.0001) but not in the NED group. The sensitivities of the MCA and the CA 15-3 assays were 84% and 78% and the specificities were 81% and 78%, respectively. The negative predictive value of 97% for MCA was significantly higher (P = 0.0001) than the 88% for CA 15-3. Thus the MCA enzyme immunoassay is at least equivalent to the CA 15-3 test and is recommended in the assessment of metastatic spread or tumour recurrence in breast cancer patients.
一种新的肿瘤标志物——黏蛋白样癌相关抗原(MCA),在176例乳腺癌患者中进行了评估,这些患者分为无肿瘤(NED,n = 141)或有转移(PD,n = 35)两类。在5年随访期间,进行了842次MCA测量和363次CA 15 - 3测量。PD组MCA水平显著升高(P = 0.0001),而NED组未升高。MCA和CA 15 - 3检测的敏感性分别为84%和78%,特异性分别为81%和78%。MCA的阴性预测值为97%,显著高于CA 15 - 3的88%(P = 0.0001)。因此,MCA酶免疫测定至少与CA 15 - 3检测相当,推荐用于评估乳腺癌患者的转移扩散或肿瘤复发。
