摘要
目的探讨直肠癌CT血管成像(CTA)分型与临床分期、淋巴结转移的相关性。方法选取2018年3月至2020年6月间宝鸡市中心医院收治的60例直肠癌患者,均给予CTA检查并进行CTA分型,判定患者的临床分期、淋巴结转移并进行相关性分析。结果60例患者中,CTA分型为A型22例,B型18例,C型9例,D型11例。CTA A型与B型患者多为临床Ⅰ期,C型与D型患者多为临床Ⅲ期,差异均有统计学意义(均P<0.05)。CTA A型、B型、C型和D型患者的淋巴结转移率分别为9.1%、16.7%、66.7%和72.7%,差异有统计学意义(P<0.05)。Spearman分析显示,CTA分型与临床分期和淋巴结转移都存在相关性,差异均有统计学意义(均P<0.05)。结论直肠癌CTA分型能反映患者的临床分期与淋巴结转移情况,可直观显示肠系膜下动脉及其分支走行,具有很好的临床应用价值。
Objective To explore and study the correlation between classification of rectal cancer on CT angiography(CTA)and clinical staging and lymph node metastasis.Methods From March 2018 to June 2020,60 patients with rectal cancer were selected at Baoji Central Hospital.CTA examination was performed on all patients for classification of rectal cancer,and the clinical stage and lymph node metastasis were assessed and correlation analysis was conducted.Results On CTA,22 patients had type A rectal cancer,18 patients had type B rectal cancer,9 patients had type C rectal cancer,and 11 patients had type D rectal cancer.Type A and type B rectal cancer were mostly clinical stageⅠ,and type C and D rectal cancer were mostly clinical stageⅢand the difference were statistically significant(all P<0.05).The lymph node metastasis rate was 9.1%,16.7%,66.7%,and 72.7%,respectively in patients with type A,type B,type C and type D rectal cancer on CTA(all P<0.05).Spearman analysis showed that classi-fication of rectal cancer on CTA were associated with clinical staging and lymph node metastasis of rectal cancer(P<0.05).Conclusion The classification of rectal cancer on CTA can reflect the patient's clini-cal staging and lymph node metastasis,and can directly display the anatomical course of the rectal inferior mesenteric artery and its branches,which has significant clinical application value.
