目的:探讨64排多层螺旋CT(MSCT)联合血清淀粉样蛋白A(SAA)在结肠癌术前分期中的临床应用价值。方法:110例结肠癌患者,随机分为A组(55例)和B组(55例),A组术前行MSCT和SAA联合评估,B组只进行MSCT评估,比较术前分期与术后病理分期。结果:实际纳入病例99例,A组49例,B组50例,2组基线情况一致。A组的术前T、N、M及TNM分期的准确度分别为81.6%、79.6%、100%及77.6%;而B组准确度分别为82.0%、60.0%、98.0%及62.0%。两组在N分期之间的差异有统计学意义,χ2=4.498,P=0.034。结论:MSCT和SAA联合术前分期评估结肠癌患者的策略可以提高术前分期的准确性。
Objective: To investigate the clinical value of multi-slice spiral CT (MSCT) combined with serum amyloid A (SAA) in the preoperative staging of colon cancer. Methods: One hundred and ten patients with colon cancer were randomly divided into group A (55 cases) and group B (55 cases). Group A was preoperatively evaluated by MSCT and SAA. Group B was evaluated by MSCT only. Preoperative staging and postoperative Pathological staging. Results: The actual inclusion of 99 cases, A group of 49 cases, B group of 50 cases, two groups of the same baseline. The accuracy of preoperative T, N, M and TNM staging in group A were 81.6%, 79.6%, 100% and 77.6%, respectively. The accuracy of group B was 82.0%, 60.0%, 98.0% and 62.0%, respectively. The difference between the two groups in the N staging was statistically significant, χ2 = 4.498, P = 0.034. Conclusion: The preoperative staging accuracy of MSCT and SAA combined with preoperative staging in patients with colon cancer can be improved.
