联合检测suPAR、SccAg在宫颈癌中的意义

Significance of Combined Detection of suPAR and SccAg in Patients with Cervical Carcinoma

  • 摘要: 目的探讨suPAR、SccAg在宫颈癌中的变化及监测意义。方法采用ELISA方法测定57例宫颈鳞癌患者血清中suPAR、SccAg值,以30例子宫肌瘤的正常宫颈做对照。结果宫颈癌患者治疗前血清中suPAR、SccAg测定值明显高于正常宫颈的血清测定值(P<0.01),宫颈癌Ⅰ~Ⅱ期血清suPAR、SccAg测定值明显低于Ⅲ~Ⅳ期者,淋巴结无转移者明显低于有转移者(P<0.01),治疗后无复发者明显低于复发者(P<0.01),而治疗后复发、术中残留对其影响不显著(P>0.05)。在宫颈癌中,suPAR、SccAg表达的阳性率分别为75.64%、61.69%。结论suPAR、SccAg在宫颈癌呈高表达,提示其可能是宫颈癌发生发展中的特征之一,有待成为术后监测、术后随访及是否追加放疗的参考指标,为判断预后、评估治疗提供帮助。

     

    Abstract: Exploring sensitive tumor markers for cervical carcinoma which can be used for correct treatment and prediction of prognosis. Methods A quantitative enzyme-linked immunosorbent assay (ELISA) was used to measure the concentrations of suPAR and SccAg from the sera of 57 patients with cervical carcinoma. The sera of 30 patients with leiomyoma were used as control. The t test, the analysis of variance and the multivariated analysis were used as statistical analysis. Results The mean level of suPAR in patients with cervical carcinoma was significantly higher than those with leiomyoma (P<0.01).The mean levels of suPAR and SccAg were significantly higher in patients with stage Ⅲ~Ⅳ than in patients with stageⅠ~Ⅱ (P<0.01). The mean levels of suPAR and SccAg in patients with non-residual tumor, in patients with negative pelvic lymph nodes and in patients whose tumor did not relapse with in six months after treatment were significantly lower than those in patients with residual tumor, positive pelvic lymph nodes and in patients whose tumor had relapsed, respectively (P<0.01). The mean SccAg level was not significantly influenced by post-treatment recurrence and residual tumor during operation (P>0.05). The positive rate of their expression in cervical carcinoma were 75.64% and 63.98%, respectively. Conclusion The high expression of suPAR and SccAg may indicate that they can be one of the characters for cervical carcinoma. SuPAR and SccAg can be used both as prognosis indicators and for post-operative radiotherapy in cervical carcinoma.
