多層螺旋CT對進展期胃癌Lauren分型的價值研究
發(fā)布時間:2020-10-28 07:38
目的:評估多層螺旋CT(Multi slice computed tomography,MSCT)對進展期胃癌Lauren分型的應用價值。方法:回顧性分析114例經(jīng)手術(shù)病理證實的進展期胃癌的MSCT影像學表現(xiàn),以Lauren分型標準分為腸型胃癌和彌漫型胃癌兩組,比較兩組進展期胃癌的腫瘤厚度、長徑、門脈期CT值、強化方式、腫瘤表面有無潰瘍情況、淋巴結(jié)分期。結(jié)果:腸型和彌漫型胃癌分別為50例和64例,兩組厚度分別為(18.42±7.40)mm和(17.17±5.14)mm,差異無統(tǒng)計學意義(t=1.07,P=0.29);長徑分別為(50.70±17.29)mm和(60.82±23.33)mm;門脈期CT值(黏液腺癌除外)分別為(75.75±15.81)HU和(85.80±18.17)HU;強化方式:(均勻∶不均勻=27∶23和21∶43);表面情況:(平坦∶潰瘍=13∶37和32∶32);以上差異均有統(tǒng)計學意義,分別為(t=-2.57,P=0.01),(t=-3.05,P=0.00),(χ~2=5.17,P=0.02),(χ~2=6.77,P=0.01);淋巴結(jié)分期與病理對照符合率分別為84.00%與81.25%。結(jié)論:MSCT對進展期胃癌的Lauren分型有較大價值,兩型進展期胃癌在腫瘤長徑、門脈期CT值(黏液腺癌除外)、強化方式及腫瘤表面有無潰瘍方面均有較大差異,CT對胃癌淋巴結(jié)分期有較高符合率。
