目的分析螺旋CT、MRI及血清VEGF-C水平联合检测在直肠癌术前分期中的应用价值。方法收集2012年2月-2015年3月就诊的直肠癌患者137例,并对所有患者术前分别进行螺旋CT、MRI、血清VEGF-C水平检测,并将螺旋CT、MRI、血清VEGF-C水平检测对结肠癌术前分期情况与术后病理结果进行比较。结果随着病理分期增高,血清VEGF-C水平升高,各病理分期之间血清VEGF-C水平差异有统计学意义(P<0.05),三者联合检测的诊断正确率高于单独使用螺旋CT或MRI检测,差异均有统计学意义(P<0.05)。结论联合应用螺旋CT、MRI、血清VEGF-C水平检测可提高直肠癌术前分期诊断准确率。
Objective To analyze the value of combined detection of spiral CT, MRI and serum VEGF-C in the preoperative staging of rectal cancer. Methods A total of 137 patients with rectal cancer were collected from February 2012 to March 2015. Spiral CT, MRI and serum VEGF-C levels were measured in all patients. Spiral CT, MRI, serum VEGF-C The level of colon cancer patients with preoperative staging and postoperative pathological results were compared. Results The level of serum VEGF-C increased with the increase of pathological stage, and the difference of serum VEGF-C level between different pathological stages was statistically significant (P <0.05). The diagnostic accuracy of combined detection of the three was higher than that of single spiral CT Or MRI, the differences were statistically significant (P <0.05). Conclusion The combined application of spiral CT, MRI, serum VEGF-C levels can improve the preoperative staging accuracy of rectal cancer.
