摘要
目的研究血清组织多肽特异性抗原(TPS)在乳腺癌患者血清中的表达水平及其对乳腺癌的临床应用价值。方法采用酶联免疫吸附法(ELISA)测定30例健康体检者、40例乳腺良性病变患者和90例乳腺癌患者的血清TPS和CA153水平。结果乳腺癌患者的血清TPS和CA153水平及检测阳性率均明显高于乳腺良性疾病和正常对照组(P<0.01)。TPS和CA153阳性率和浓度均随着临床分期的进展而升高,而TPS在临床期也有高水平表达。TPS对乳腺癌骨转移最为敏感,远处淋巴结的乳腺癌患者水平最高(P<0.05)。乳腺癌患者治疗有效后血清TPS和CA153水平均明显下降(P<0.05),尤其以TPS下降幅度较为显著(P<0.05)。结论TPS是诊断乳腺癌的一项敏感性强的肿瘤标志物,尤其是骨转移患者,对乳腺癌诊断、病情判断和疗效评价等均有重要价值。
Objective To investigate the expression of serum tissue polypeptide-specific antigen (TPS) in breast cancer patients and its clinical value in such cases. Methods Altogether 160 subjects (90 patients with breast cancer, 40 with benign breast lesions, and 30 healthy subjects) were enrolled in this study. The serum TPS and CA153 levels were measured by ELISA in all the subjects. Results The levels and positivity rate of serum TPS and CA153 in breast cancer group were significantly higher than those in the normal subjects group and benign lesion group (P<0.01), and became even higher as the malignancy progressed. High serum TPS level was detected in the cancer patients in stage Ⅰ. Serum TPS level was the most sensitive to bone metastasis of the maligancy, but its highest levels occurred in cases of lymphoid node metastasis (P<0.05). In patients who responded favorably to the treatment, serum TPS and CA153 levels were significantly reduced (P<0.05), but the reduction in TPS levels tended to be more obvious (P<0.05). Conclusion Serum TPS can be used as a very useful and sensitive tumor marker in the diagnosis of breast cancer, especially in case of bone metastasis, and may be of great value in clinical decision-making and assessment of therapeutic effect.
