  • Effect of MultiSlice Spiral Computer Tomography Combined with Serum Amyloid A Protein on Preoperative Rectal Cancer Staging

    摘要:目的: 探讨64排多层螺旋CT(MSCT)和血清淀粉样蛋白A(serum amyloid A protein, SAA)联合术前评估直肠癌在肿瘤分期诊断中的作用。 方法 :纳入经根治术治疗的直肠癌患者通过MSCT扫描进行评估,同时取患者静脉血测量术前SAA水平,行MSCT分期与MSCT和SAA联合分期以比较二者的诊断价值。 结果 :本研究纳入患者121例。MSCT检测T分期的准确度为851%。在评估淋巴结转移方面,MSCT和SAA联合分期的准确度为760%,明显高于MSCT分期(595%, 〖WTBX〗P lt;0001)。MSCT正确判断所有远处转移。同单一的MSCT检测相比,MSCT和SAA联合评估能显著的提高术前TNM分期的准确率(785% vs. 636%,〖WTBX〗P =0011)。 结论 :MSCT联合SAA检测比单一的MSCT检测显著提高了直肠癌术前肿瘤分期和淋巴结转移方面的准确度。这种新的术前评估方法的为肿瘤进展评估和术前治疗决策提供了更加可靠的信息。Abstract: Objective: To determine the role of combinative assessment of 64 multislice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) in preoperative rectal cancer staging. Methods : Enrolled consecutive rectal cancer patients undergoing curative surgery were evaluated by MSCT scan. Meanwhile venous blood specimens were taken to measure preoperative SAA concentration. Both MSCT staging and MSCT plus SAA staging were performed to compare with each other. Results : The study population consisted of 121 patients. The accuracy of T staging was 851% for MSCT. The accuracy in evaluating lymph nodes metastases was 760% for MSCT plus SAA compared with 595% for MSCT alone (〖WTBX〗P lt;0001). All the distant metastases were correctly detected by MSCT. The method combining MSCT with SAA led to significant improvement on preoperative TNM staging compared with MSCT alone (785% vs. 636%, 〖WTBX〗P =0011). Conclusion : MSCT plus SAA showed greater accuracy than MSCT alone in rectal cancer staging and lymph node metastases. This novel strategy of preoperative evaluation appears to provide more accurate information on tumor progression and preoperative therapy decisionmaking.
