Abstract Objective: To investigate the value of multi-slice computed tomography(MSCT) in Lauren classification of advanced gastric carcinoma. Methods: MSCT imaging findings of 114 patients with advanced gastric cancer proved by operation or gastroscopy biopsy were analyzed retrospectively. All cases were divided into two groups, intestinal-type(IT) and diffuse-type (DT), according to Lauren classification standard. The thickness, long diameters, CT values of portal venous phase, enhancement patterns and surface of the tumor were compared between the two groups. Results: A total of 50 and 64 cases were found in IT and DT gastric carcinoma. The thickness of two groups were (18.42±7.40) mm and (17.17±5.14) mm, the difference was not statistically significant(t=1.07, P=0.29). The long diameters were (50.70±17.29) mm and (60.82±23.33) mm, CT values in portal venous phase(except mucinous adenocarcinoma)(75.75±15.81) HU and (85.80±18.17) HU, enhancement types(homogeneous:inhomogeneous)=(27:23) and (21:43), surface condition of the tumor(flat:ulcer)=(13:37) and (32:32), the differences were statistically significant, respectively(t=-2.57, P=0.01), (t=-3.05, P=0.00), (χ2=5.17, P=0.02), (χ2=6.77, P=0.01). The coincidence rates of lymph node staging and pathological contrast were 84.00% and 81.25% respectively. Conclusion: MSCT has important value in Lauren classification of advanced gastric carcinoma. There are significant differences in the long diameters, CT values in portal venous phase(except mucinous adenocarcinoma), enhancement types and surface characteristics between IT and DT gastric tumor. CT has high coincidence rate with lymph node staging in gastric cancer.
